Mp3 playback battery life /w headphones
Does anyone know if the mp3 playback time changes if your using a set of headphones, or is the 24 hours assuming you are using headphones?
The playback time would vary based on any number of factors:
Temperature, volume, other operations, how long the screen is on, how many times you change the volume, eq settings, if airplane mode is on or off, any calls, e-mails, push on or push off, how often to fetch mail, screen brightness, 3g on or off, wi-fi on or off, location service on or off,etc.
The 24 hours is based on a specific situation and is not likely to be reproduced with normal use.
Just use it and see what you get.

Pick up metal objects with zen micro headphones? battery life with firmware 1.02
hey all
just purchased my zen micro couple days ago.
the package we got here in downunder is satifying. included were the wired remote and also the stand/case with belt clip. these were the only reasons that made me choose this over the ipod mini.
this has not occurred to me until tonight, but the headphones seems to act as magnets and were stuck to each other as the phones were dangling
i never noticed this happening with other phones
also the battery life of my zen was horrendous. its lasted 5 hrs with eq and smart volume on. the zen was on hold the whole time as the actions were controlled by the wired remote.
this was with the firmware that was shipped with the player .0.03 i believe
have just updated the firmware now, and will be testing the battery life to see if the problem is rectified.
if not, then an exhange for an ipod is inevitable.Yep, SV is a battery killer, around a 50% drop in life has been meaured and the effect is known to be pretty negligible.
And as others have said, them headphones have magnets in, like pretty much any speaker -
Does using bluetooth headphones dramatically decrease battery life in ipod 5
I have a 64gb version of the Itouch 5 and recently started using jaybird brand bluetooth headphhones. At first everything worked fine but now the battery inthe Ipod only lasts 4 hours even when niot using it. Has there been any known issues with this?
Yes, and no. The headphones aren't sucking the battery out of your 5th Generation iTouch. USING BLUETOOTH, will. Its like running a game on your iPod for a while. It will drain the battery more quickly than with just listening to music. So running apps, bluetooth, etc, WILL shorten your battery life.
HOW TO FIX IT:
When you are not using the headphones, turn the bluetooth off through the general settings in your itouch. Then, while you aren't running the headphones, it won't suck the battery life out. When you use the headphones, turn bluetooth back on. Leaving bluetooth on is still leaving the iPod in bluetooth mode, which is running down the battery because it takes extra charge to run bluetooth. Hope this helps! -
Using mp3 (for example 92 kbps) instead of wma (28 kbps) does improve battery life?
JK23 wrote:For NiMH batteries, the self discharge depends greatly on the temperature. At around 70F it is only around % a day, but at around 00F it is around 3% a day. Those numbers are after the initial first day drop. The first day drop isn't 5%, but might be 5-8% or so.
this coincides pretty closely to what i've read also. recharable batteries do self-discharge faster then other batteries but it's not 5% in the first day. they discharge like % per day. regular alkaline batteries discharge at like 3-5% per year. Li-ion discharge slower then NiCd, etc.
Here are some interesting reads.

How long can you play mp3's/maximum battery life?
What is the average battery life for a 30 gig, early 5th generation Ipod video? I'm asking as I get about 5 hours using Apples instructions for maximum battery life.
Usually, the battery life for the original Fifth Generation iPods was approximately 12-15 hours, I think, although I'm not perfectly sure about that estimate.
Anyways, about 5 horus is not normal for your iPod, and I woulkd suggest that you send your iPod in for service (if it is still under warranty).
To arrange an iPod service request, see here: Placing an iPod service request

Message Edited by hippon2 on 0-8-200707:36 PMok, I will tkae that under consideration. Now I have another battery issue, after fully charging the MP3 player I noticed that the battery life drain rather quickly while it is off. I lost 9% of it's charge from taking it off the charger at midnight and then plugging it into the usb port of my computer the next morning at 10:00am. The clock is turned off so it should not be doing anything for those 0 hours.

Please give me your battery life experiences
Hi there,
Just got my first Nano. I love the unit itself. The sound far surpasses my expectations and its the first jukebox MP3 I love.. but..
the battery life is just dreadful for me. I'm getting about 5 hours or so, thats with brightness down, backlight at 2 seconds, and I'm only taking it off hold to change albums or pause! Is this common? If not I will get an exchange, if it is I will just send it back. Disappointing because otherwise it's great!I've also had poor battery life until now.
I tried to switch off certain settings I chose when first configuring the Nano.
Specifically, I diselected EQ, cross fade and sound check, all in Settings/ Playback.
I also dimed down brightnes a bit, so it's about a third now (I had it in 50% before).
I last charged the nano on monday night and I charged it again on wednesday night when it still marked about 10% of the battery charge. So, I had about 48 hours of music and video, not continously of course.
In total, I must have played like 3 hours of video (games) while listening to music.
When I had those mentioned playback settings on, the battery would drain in less than 24 hours, so I can tell now how much power they (and probably other settings as well) take from the battery.
I'm much more satisfied with my purchase now, but I was seriously considering selling the nano and buying either a Classic or a Touch.
I hope this help other people having short battery life to improve the performance of their nanos. Let us all know how you do. -
Creative Zen X-Fi Battery Life
I just got a new Creative Zen X-Fi 32GB player a couple of weeks ago. One of the selling points for me was the stated 36 hours of audio playback time. However, on my first two charges, I have only gotten about 2 hours of battery life, with usage as follows: no X-FI, no Wi-Fi, player locked about 90% of the time so that screen is turned off, a litle bit of usage with the headphones on and volume set at or 2, and the rest of the usage with volume set at 0 to 2 and using either the external speaker or with the player hooked up to an FM transmitter in my car.
What are others experiencing? Any tips on getting the claimed 36 hours? Is that possible only with all usage with the headphones and the volume set very low?brubenking wrote:

player locked about 90% of the time so that screen is turned off, This will get you the longest runtime. External speaker & playing video will really use up the battery. -
Gingerbread OTA and battery life issue
I received the Gingerbread OTA update. I am still working through testing everything to see if the phone is now the way it should be, but I keep stumbling on 1 issue with the battery life.
Yes my battery is now over a year old of occasional use.
When I first got the gingerbread update I had 100% battery and applied the update.
That day I got over 9 hours straight of MP3 playback over Bluetooth using the stock music player.
I charged the battery to full that night and left it on the charger overnight.
The next day I got 4 hours straight of MP3 playback over Bluetooth using the stock music player.
I charged it up 100% at work and proceeded to get another 4 hours straight.
Since that day I have never seen the 8 hours again.
One interesting note is that in the 4 hour increments the music player will stop when the battery hits the orange low warning. I can switch over to streaming music videos and play for another hour till the battery fully dies.
I have tried to recondition the battery using some information I found.
I have factory reset the phone and updated stock apps only.
I have factory reset the phone and never logged into the market place to keep apps from auto updating.
I have noticed on my factory resets things are different. It wants to erase the SD card. You can do the factory reset without erasing the SD card. I am not sure exactly what the difference is there and why the default is to erase the SD card. Sadly both factory reset are not behaving as the previous one did. Normally after the factory reset the setup wizard would start and help you activate your phone. It seems the new default is to not run that process or I got a bad update on my phone.
I have also noticed as a user here suggested that after the phone reaches 100% charge, even though it is plugged in, the phone seems to switch over to using battery mode draining the battery and never topping it back up since it still plugged in.
Shouldn't a year old battery last longer? Shouldn't I be able to stream music for longer than 9 hours? I don't have the screen on, all interaction is through the Bluetooth headset, doesn't mater if email is on with push mode or totally off and not even activated, no calling, no text messages, and just solely trying to listen music like a mp3 player.
Suggestions?
Is your Samsung Fascinate Gingerbread OTA doing the same things?A master reset definetly did not solve the issue for me.
On my last and most recent reset I noticed it did execute the setup wizard like it had done prior to gingerbread. This time I did not configure anything on the phone and just left it sit. I never opened the market either. About an hour later i got tired of no phone and started the wizard on my own so that the phone was at least activated. I did not configure any additinal email accounts just the standard single google account for my phone withthe gmail program.
I charge the battery to 100% with the phone on
Unplug the ac charger from the phone
ask the phone to power down
wait another 2 minutes after the screen goes black and the buttons are no longer lit
plug in the ac charger and it will top up the battery to a full 100% and not the OS 100% that it thinks it should be
Most nights i just leave it off charging to that last 100% since i have seen problems with trickle charging after it reaches 100% int he OS and then starts using the battery the rest of the night!
Next morning unplug the AC charger and ask the phone to boot
I got 8-9 hours playing mp3s streamed over bluetooth, 1 text message in and 1 text message out, but no phone calls and no other activity on the phone. Not bad but i feel it should do better!
I actived 3 exchange email accounts in push mode. I had heard push mode was supposed to be the best battery saver. Well with the included email (not gmail) app my battery went down in less than 4 hours! Today i have forced the email to manual mode instead of push for peak and off peak times. I will see if i get 8-9 hours again.
The rest of the phone is all factory defaults, boring, and pretty much useless. So much for a smart phone being smart and handy. Guess i need to buy about 3 batteries to get through a day and find a way to charge them as i run around throughout the day without ac or a way to charge. -
Difference in battery life between MDR-ZX550BN and BTN200?
I am looking to buy either the MDR-ZX500BN or the BTN200. There are, however, some information that I can not seem to find or get confirmed anywhere. Therfore I hope that it can be sorted out here.
The differences that I can find (correct me if I am wrong) with the newer MDR-ZX500BN are:
- Texture (material?) on the earcups and hinges have switched (metalic and platic)
- Noice canellation (90%)
- Minor changes in button layout (button for anwsering calls)
- 10 grams heavier.
Another thing I noticed is how it claims a battery life that support up to 25 hours of music playback, while the older BTN200 calims 40 hours!
At first I wash shocked at the Idea that Sony would cap their own product like that (only 62,5% of the previous model's capacity).
I personally do not care for the nocie cancelling feature that much and would rather have the extra battery life (especially if that feature reduces the capacity as much as it has done in this case).
Then I thought it made more sense when I read that the 25 hours is measured when noice cancellation is ON.
Though, I can not find any information on how long the battery lasts when the nocie cancellation is OFF.
Some of the questions that this raises:
- These models look quite similar and the older BTN200 seems to be going out of stock soon, but the names are not very similar at all. So is MDR-ZX550BN really a successor to BTN200?
- Are there any minor or major differences, other than the ones that I listed before?
Last and certainly my main question:
- How long is the expected (up to) battery life on the MDR-ZX500BN when the nocie cancellation is OFF?Never mind.
I found it.
However, It says nothing about it on Sony's dedicated website for my country (Sweden).
I found it on the US website.
It can handle up to 29 hours of music playback with the noice cancellation OFF...
That is still less than 75% of the older and much cheaper BTN200.
Sony... this is not good.
While 29 hours is still quite good. The much higher price (effectively the double in stores, here in Sweden) and extra (even if it is minimal) weight, just won't cut it when your older version is way better.
I have not tried the noice cancelling feature on this particular model. But a lot of reviews says that is the weakest noice cancelling that they have experienced and that it is quite useless.
What the older BTN200 had going for it, was low weight, low price and the most astonishingly superior battery life. If something that makes a more universal impact on society, like an electric generator, was engineered to be as efficient as the BTN200 is among bluetooth headphones, I bet Sony would win the Nobel prize.
The successor MDR-ZX550BN has managed to be worse on all these points, is just generic and hardly worth the price it has.
I have decided that I will buy two (maybe more) BTN200 for the price of one MDR-ZX550BN. So that I may have a some spare ones, just in case Sony does not improve on upcoming versions.
If someone who reads this has any power to influence Sony's decisions on future models. Please make them realize this! -
Solved!
Go to Solution.IMPORTANT Notes while charging your Reader device:
It is recommended to charge the Reader using the supplied AC Adapter. When using the AC adapter to charge your Reader device, the lightning bolt symbol that appears next to the battery icon [FIG. 1] on the display of your Reader device is an indication that it is connected to AC power and is charging the battery properly. If the lightning bolt symbol is not present, double check the AC Adapter to ensure that your Reader device is properly connected. This symbol does not appear while charging via a USB connection.
If you charge via a USB connection and leave your Reader Digital Book connected to the computer to charge and the computer goes into sleep/hibernation, charging will stop and the red charge indicator on the Reader will turn off. If left connected, your battery may begin to discharge. To avoid this, turn off any sleep/hibernation settings while charging or set your sleep or hibernation settings to come on after your Reader Digital Book has been charged and then disconnect it from the computer once charging has completed.
It will take approximately 4 hours to achieve a full charge with a computer. It will take approximately 2 hours to achieve a full charge with the optional AC Adapter.
If your Reader Digital Book is left connected to a powered USB hub while the computer is shut down, your battery may begin to discharge. Disconnect your Reader from the hub when the computer is not powered on.
Always verify that your Reader is fully charged by disconnecting it from the computer and checking the battery indicator. The battery indicator will display 4 black bars when it is fully charged
On a full charge, the battery has the capability of up to 7,500 continuous page turns. Actual battery life will vary based on usage patterns, settings and battery conditions. When the Reader is turned on, off, or a page is marked, battery power is used, thus lowering the expected battery life.
NOTE: When storing the Reader for a long period of time, use the Device Shutdown feature in the Advanced settings menu. After using Device Shutdown, it may take approximately 30 seconds for the Reader to start the next time the Reader is turned on.
Playing audio will reduce the battery life. If you did not start audio play back intentionally, confirm audio is not playing. You will not hear playback unless headphones are connected. Audio playback will continue until it is stopped by turning it off from the Now Playing menu. To see if audio is playing, press the HOME button and then press the OPTION button. If Now Playing is displayed in the dialogue box that appears, tap Now Playing and this will take you to the song that is playing. Press the Pause button to stop playback of that song and then press the HOME button.
NOTES:
Due to the nature of the E Ink electronic display technology, the LCD can retain an image without having power. Turning the page is the only time power is consumed. If the Reader's power is drained, the LCD will retain the last image that was displayed, thus making it appear like the Reader is frozen and in some instances it will not have enough power to perform other operations such as turning on or off.
Battery life can be affected by operating temperatures below 41 degrees F, lack of use, or if the battery has not been given enough time to fully charge.
As with any battery, if the Reader is stored for an extended period of time, the battery will discharge on it's own. Therefore, it may be necessary to charge the battery prior to use.
If the Reader has not been used for an extended period of time, repeatedly charging and discharging will improve the efficiency of the battery.
If the battery life still seems short, the battery may need to be replaced. -
How is your battery life? (on new ZEN on
Well, after the firmware update I thought I'd give it a try and see how long it would last.Last time I did this I got 22 hours, with the first update, the sd card one. This time it ran for 28 hours! With volume 5/25, when I did my last test with 22 hours, I only had it at 5/25 volume.No EQ, no smart?volume, no bass boost etc...And most of my music is 96 kps wma or 28 kps mp3 with a few 92 kps mp3s I've downloaded recently. Then while I'm doing?the test, I'm looking at the Zen page to see how they got battery life(sometimes they say half volume at 28 kps mp3 etc) and I noticed they upped it to 30 hours life instead of 25!Now I don't feel so special. :P?So, I just want to know how much juice you get out of your ZEN?And say if you use eq, volume level, bass boost, kps, etc
Hi guys, you will not keep your player on all day long, so you will not get those?playback durations in normal daily use... i tried all the f/w and now i?use my zen?with the .03.04 f/w and it gives me about 4-5 hours (EQ on, Bass Boost and Smart Volume off and i browse the player much)... yesterday, after an approximately 3 days of daily use (4-5 hrs/day) it got down to the final bar... This is better?than the new f/w?s?for me because when I turn it off with the new f/w s it drains quickly because of the hot standby mode... if you have any solutions for this issue (except leaving it turned on ) i will update my f/w too... coz i can not use my SD card as well as i want to especially while watching video...

What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...
Please don't post your questions, usage screenshots, or claims that it worked or not for you or anything here except PROCEDURES/DEBUG STEPS/SOLUTIONS or improvements to the procedures already listed here. Try to use point form and to be as concise and clear as possible. Hope all this helps.
Thank you and good luck!
General info and specs
First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
http://www.apple.com/batteries/iphone.html
http://www.apple.com/batteries/
... you didn't read it? loll Always remember this i.e. the definition of "usage":
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
Optimize your settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
Standby time: Up to 200 hours (0.5% per hour drain)
Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
Video playback: Up to 10 hours (10% per hour drain)
Audio playback: Up to 40 hours (2.5% per hour drain)
So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.
Apple's test methodology for claiming the specs:

Procedures
davidch tips (reset+full discharge recharge):
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (tilll it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!
ram130's variant of davidch i.e. additional steps:
Now using davidch original steps and attaching the tweaks I made to get me more usage. As shown on page 29.
Go through these steps to address the battery after updating to iOS 5.0.1:

2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (till it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the infrared is off after the reboot).
7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
* I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
buxbuster tips(wifi sync, iCloud):
These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
Workaround number 1. Deselect wifi-sync in iTunes and press sync.
If that doesn't work try :
Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
rolandomerida tips - i.e. buxbuster and additional steps:
Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
This is what I did:
1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
4.Turn Wi-Fi on.
5. Add the iCloud account again.
That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place

Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
As for 4S battery life. Try doing this,
1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
2. Settings>Notification>Calendar ... turn off the Notification Centre.
3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
Try these 3 steps first... if it still drains a lot, try the following,
4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ... tap backup to iCloud from your iPhone. It will take a while if the file is huge.
Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
Once it's all done restored. Turn off your iPhone,.. and turn it on again.
Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
Good luck. Let us know if it works for you.
W. Raider tips (Sirii):
Bottom line for me of things that helped battery life are:
1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
Hope this is helpful!

jmm514 remarks (Twitter):
I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
tmksnyder comments (notifications, corrupt data in iCloud):
For me, I found my iphone on wifi mysteriously connecting to my mac. I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud. The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x). Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone. It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification). I also found that iCloud control panel on OSX would error if I tried to delete the file. I fixed it by removing the App and doing a hard reset which stopped the sync. I probably could have turned off iCloud document sync in the phone but didn't think of that. My battery life has greatly improved while at home on wifi. I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery. It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage. My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby. I was amazed. Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event. I could drop my percentage by 5-10% in a matter of minutes when doing updates. I think a lot of our problems are background processes, associated with iCloud, notification, and apps. More features means more battery. I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden. It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks that occur for the service on an os level not an app level. This minimizes the load so there arent a bunch of apps all runing and constantly checking. The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone. No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed. If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery. I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message. On nights I get no notifications, I see a 3 or 4 percent drop. On nights with a number of notifications, i have seen up to a 10 percent drop. Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain). For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info. I think it has a good overview of how the notifications work.Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable.
Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent. If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)

The original solution still represents a high level of success for users having any battery issues.
Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
Make sure your device can run iOS 5.0.1 and is not altered.
Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
Reset the device doing a hard reset and software reset.
Let battery drain and then charge for the full cycle, which is 24 hours.
I think you will find you will get the battery usage that APPLE has stated for the device.
Best of luck, stay safe and thanks -
Does new 30 GB iPod have longer battery life than original 5th gen 30
The claim from Apple is that the new 30 GB iPod has a brighter screen and that the battery life during video playback is 3.5 hours. The original 5th generation 30 GB ipod only claimed to have 2 hour battery life during video playback. Does anyone know if the new 30 GB iPod actually has a better battery or a more efficieant screen than the original or if these claims are only a result of the new iPod bios (version 1.2) which gives you a brightness control. Is a new 30 GB iPod better than a original 5th gen 30 GB iPod which has been updated to v 1.2?
AMD64 Windows XP Pro 5th Gen 60 GB iPod VideoLet me first not say Ha ha but The fourth Gen photo people said the same thing about when the fifth gen came out and we all complained. Also now that gapless playback has come out we all complained. So all I have to say is that at least you got the quick letter thing when you scroll and the games as well as gapless where we got nothing. I have owned an Ipod since the first gen and let me say I am supprised that apple even gave you guys some update. For all of your complaining, get in line.

Battery life and downloading iTunes
Hello Everyone:
I am once again having more problems with my iPad since updating with the IOS 8.3 system. I will discuss that in another forum. I am also having ENDLESS problems with my latest ipod Shuffle device. This is the 5th iPod shuffle I have had to buy in the past 2 years all because of the same issues. No matter that Apple is at fault with device defects, they still make me buy replacement devices. Plus, the earphones that come with the iPod shuffle are worthless, in that I use my iPod shuffle for running and the earphones are to large to stay in the ears while running so in addition to the $50 for the shuffle device and hundreds of dollars for the iTunes songs, I've had to buy extra headphones that stay in the ears while running. I have approximately 200 songs purchased from iTunes as well as numerous purchased software applicatioms from the Apple store. If I didn't already have so much invested in these items, I would stop buying Apple products. Every one of the five iPod shuffle devices I have purchased in the last two years, they burn out the battery after 40 or so recharges. After 6 or 7 recharges of a new iPod shuffle, it gives less and less battery time. I just bought this latest iPod shuffle a couple of months ago and even though I recharged it all night long, the next day after only playing it for 10 minutes the alert voice came on to warn me that my device battery was low and needed to be recharged. The last device I bought just two months before the latest one, I accidentally bumped it on the ground, hardly anything, but it dented it and would no longer play stereo, but Apple said I had to buy another one. (I fear what Apple will be tell everyone when the least little defect happens with the new Apple watch!) There is clearly a defect in the Apple ITunes program or in the shuffle manufacturing factory that encodes these shuffle devices to start recharging less and less an amount of time with a recharge. This has to be the case because this has happened with, not just one or two iPod shuffles, but with FIVE devices I have purchased in the past two years. I like using the iPod shuffle when I run because it is so small. However, this constant, constant, constant defect in the recharging and expense to buy new ones because the battery life is run down to 15-20 minutes, is tiresome and not worth it anymore. When this first started happening, I COULD NOT BELIEVE IT when I went to the Apple Store and was told that replacement batteries were $50, the same price as the device itself. I feel this is a total scam by Apple to force people to buy more devices as customers are burdened with all the music they have already purchased so they have to have a workable device to play the music. I have repeatesly had problems with Apple accessories which I have had to replace because they break down in a short period of time, like recharge cords, Apple changes the model forcing customers to buy new rechargers because the old ones don't work with the new device, the iPad covers tear and wear out and have to be replaced after six months, on and on. NOW, also, since updating to the IOS 8.3, my songs do not upload into my shuffle afted purchasing them from iTunes. I went to play my shuffle and the four new songs I purchased didn't even transfer from my iTunes account. This happened a couple of weeks ago too and I had to have a Apple support staff take me through a re-install of iTunes just to get music that wasn't even showing up in my purchased songs even though I had emails proving I had made the purchases. I simply want what any customer expects: the goods and services I have paid for and not having to spend hours and hours searching for solutions to company caused defects. It's not right!bootlegged songs really make no difference on battery life.
the apple "genuis's" told me this too. I figure it's a complete falsification.
the only thing that i could figure why they could always say that without getting sued or something, is that constant change in the filetype may cause some battery lag. if you feel like it you can go to select all the songs that aren't the most common type in your library and convert to that format. and it might help a little. It won't make much of a difference.
and contrary to the other person you probably should have posted in the ipod forum.
you should probably do a battery test yourself.
1. bring up to full charge
2. turn off EQ, backlight, and shuffle
3. put contrast right in the middle.
4. turn on repeat
5. leave it playing continuously somewhere and check it every hour or so to see if it has run out.
this will give you a good idea of how well the battery works.
