Battery Life/3G Speed - Getting Better

For the first week of having my 3G, I was very close to taking it back. I did the reset to get my phone up to date on the last build for the 2.o software. I love the software and the connectivity to our Exchange server. Works flawlessly, and amazingly fast even when 3G is off.
Here is what I did for the battery...
WIFI when I need it
3G when I need it
Turned Push off for my mobile me accounts, because I dont really need PUSH for those and Exchange works with out the push on
Turned off SHOW traffic on the maps and the GPS, unless I need them
I use my phone so much that for the first 7 days, I was charging 2x a day. I was getting pretty concerned as I was charging my 2G iPhone every day, but it usually had .5 to 2/3 life left after a full day. Today, as I type this, on a slow day I have used the phone about 3.5 hours, mostly music, web, email and a few calls. I have 70% of my charge left after the 3.5 hours and 12 plus hours of standby.
The true test will be tomorrow, when I get to work and add the heavy phone use.
As for the 3g, I have been using the iphone speed test and have found that while the 3G speed is not as blazing as I thought, when I switch between 2G and 3G, the speed is at least twice as fast if not more. What I did not realize before is that my 2G was just slow as heck. I have had as much as 5 bars in Chicago, near Ohare, Austin downtown, Houston Galleria Area. I have tested 2G vs. 3G in each location and each time it has been 2xs as fast.
Anyhow, more battery studies coming this week, with music play time.

Try running powercfg -energy from the command prompt. It might provide a few clues as to why you're seeing such low battery life.
Also check to make sure that Optimus isn't running when it's not supposed to be: http://forums.laptopvideo2go.com/topic/26992-optimus-test-tools-finally-in-users-hands/

You will need to ask beta related questions in the private developers forum. You do know how to get there, right?

What is average battery life everyone is getting for the Zen Mic

I just got my Zen Micro last Thursday. I'm concern about the battery life. I haven't fully tested the battery yet, but I'm estimating that I will only get about 6-7 hours for it. The advertised time was suppose to be as much as 2 hours. Now I know that depends on your usage (e.g. volume, bitrate of the file, play mode, etc.). What are other people getting? Thanks.

My last test, I tried to be as natural as possible. That is: back light is on; shuffle mode is on; eq is on; volume is normal (at 4 to 6); I skip or go back to tracks; I fast foward; the contrast is at 50 percent; average bitrate (from 28 to 360); smart sound off; and other minor things that I can't remember. That test gave me only 7.5 hours.
I think that is pretty modest usage. Any average mp3 user would do the same thing. Yet, I only got 7.5 out of the possible 2. I don't like the sounds of that.
I'm running another test right now with the same conditions above, and I'll let you guys know what I get.

Will Windows 7 via Bootcamp decrease the battery life or speed when running OSX?

I know that when Windows 7 is running my battery life will decrease dramatically, but I am curious is I need to worry about battery life when running OSX, or even the speed of my notebook.
Kyle

No need to worry, Bootcamp is a separate bootable partition and OS X isn't even running, the two operating systems have nothing to do with each other.
Now if you run Windows in OS X using virtual machine software, it's very much possible the extra CPU load could shorten the battery life as your running two operating systems at once and virtual machine software in addition to other software running.
However it's much safer, easier and more convenient than the hassles of Bootcamp and handling malware infections there, as OS X is always in control of the hardware.
Windows in BootCamp or Virtual Machine?

Definitive Answer: Battery Life and Speed with FileVault 2

How much speed loss can I expect to see when turning FileVauly 2 for Lion on a 2.4GHz quad-core MacBook Pro with a 256GB SSD, 4GB RAM and 1GB graphics?
This would be for things like Safari, Skype, iTunes, Coda, Chrome, Firefox, Pixelmator, iPhone running at the same time sometimes (but mostly just a few at once).
How much battery life can I expect to lose with the same questions in mind...?

I've been running FileVault 2 for a while on my MBP SSD, and while there are not noticable speed losses, the battery life has been severely diminished. Any solutions to that?

IPhone 4S Battery Life: Best solutions and procedures for 1st time user: 1-Do you have a battery life issue (learn first what the usage time spec is about) 2-What can you try to remedy the situation without reading 500 pages of posts

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.

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.

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
This is the MacRumors discussion:

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!
Comments
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.)
http://mcaf.ee/ricdt
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

HT201401 Can anyone confirm that 12 hours of low to moderate use is acceptable battery life for an Iphone 5. That is all I am getting. I am using the phone less than I have used any Iphone I have ever had. The battery life between charges is less than hal

I am very disappointed with the battery life I am getting out of my Iphone 5S 64G. I charge it every night, and would be lucky to make 15 to 20 minutes of calls during the day and yet I am lucky to get much more than 12 hours of life out of the battery.
I have to make a conscious decision not to use it to avoid it running out on me. I had it back to the Apple Store last week and they ran diagnostic checks on ot and said that the hardware was within specs.
They replaced the software as it was showing that Springboard had crashed on several occasions. The other problem I was complaining about was that at least 2 or 3 times a day, the phone would refuse to wake up when I hit the home button. It would take sometimes up to a minute of pressing the button before anything would light up. The guy at the Apple store said that this was caused by Springboard crashing and that this would also be what is reducing the battery life.
I did notice that after they replaced the software, the waking up problem appeared fixed for a few days, but the battery life had not improved. Now the waking up problem is starting to return.
It is very annoying and somewhat embarrassing when you are with a client and go to make a call and your shiny flashy new Iphone 5 won't even light up. Especially when you have to borrow your clients Nokia....

My best bet would be to restore the phone. Back it up to itunes, and then reset it Factory settings. This way, any corrupt software will be removed, and you can start fresh. Make sure you back it up first. By the sounds of it, you are using the phone for business and probably need the data from it. Hope this helps!

Centro Battery Life

After 3 Palm PDAs, I was excited to get a Palm Centro. In the first 30 days it became obvious battery life was horrible. Best Buy swapped first the battery, then the entire device. After that they referred me to AT&T who swapped the phone and at least 4 batteries until the 1 year warranty ran out. AT&T was very helpful during the first year warranty period, but I've still got 8 months on my contract, and my battery does good to last 6-8 hours. Charging it for use first thing the next day isn't possible. I make very few phone calls, literally 2-3 a week, so it's totally standby time I'm fighting with. I don't use any data connections (no e-mail, no gps, no web). I don't use texting or any third party software. I turn bluetooth off except for once a month to sync with my Vista 64 computer. AT&T has checked the settings and found nothing wrong. I'm reluctant to spend $50 for a battery that will only last a month or two, I might as well buy an I-Phone for that price (except I don't want the required data connection). I've even tried turning the radio transmitter off, charging it at 11 PM, and the next morning, it's still dead! Just totally unacceptable, and before now, unlike Palm quality. An e-mail from Palm today advertising the new palm pre plus just set me off. Why would I upgrade with my experience with Palm's quality and response to a major issue. I thought I was alone, I wish I'd read all the reviews before I bought my Centro, I would have continued using my old phone, and will probably have to go back to it if I every want to make an actual phone call.
I would expect Palm to replace the battery for at least the first 2 years when it's obviously not a user issue!

I'm in a great coverage area and battery life isn't any better if my radio transmitter is turned on or off. Also brand new batteries seem to work fine for several weeks to a month or so, then start degrading. I followed the manuals and AT&Ts recommendation to the letter on charging & recharging. My wife's Centro is in the same location and has almost identical usage and works fine. I've had lots of suggestions and "it might be's" and tried and eliminated them all, and still have a battery that won't hold a charge.

Massive battery life drop after Internet Recovery OS re-install

Hey,
A couple months ago, I made the brilliant decision to try to install Windows 7 with Boot Camp at 3am on a weekend after several days of no sleep (unfortunately, this is one of the least-poor poor decisions I've made recently, but I suppose that's for another forum). Long story short, Og turn on MacBook, Og open Disk Utility, Og click-click, SSD go bye-bye—formatted, every last bit of it (haha, me make pun-pun!). Luckily, ML ships virtually tard-proofed, so there's little I can do besides showering with Bernie (this pun courtesy of the 'lil sis; I'm innocent) to make him breathe his last. This little bit of Apple genius is irrefutable proof of God—praised be his noodly appendage. But ever since Internet Recovery blessed me with Bernie II (R'amen), I've noticed during countless nights lying with him in bed that his stamina has decreased significantly, versus his pre-IR days. I can't give you firm numbers of his endurance before the operation, but now, after even the least vigourous play, he's drained beyond further exertion after no more than 2-2.5 hours. I've tried various tweaks to increase battery life—making sure his mail parts are only shooting off when I work them manually, the same for receiving messages as well, and I've been monitoring his GPU usage; thanks to ML he's much more conscientious about being discrete, and I rarely have to limit him to using his integrated components. (Note: I'm using writing this as an excuse to start an essay, and its foundation really needs to get laid ASAP, so unfortunately the allusions/euphemisms stop here.) Again, I can't give precise numbers about its original battery life, but I was blown away by it, likely averaging at or in excess of the advertised 7-hours. I'm a geek and spent my childhood with eyes never further than a couple of inches from my CRT (and have the vision to prove it), but I really have no f'ing clue what would be causing this. I never doubted that the battery life decreased (and dramatically so), but now that I've started booting up into Windows regularly, any trace of doubt has vanished. Using Windows 8 set on Maximum Performance (and, as I'm sure most of you are aware, Windows only uses the discrete GPU, even when doing nothing graphically-intensive), the battery life is still significantly better than using ML. I've searched and searched and searched and can't find a single reference to this issue online. I'd appreciate any help you can offer. Just in case it's of any assistance, I'll put some might-be-relevant-maybe info below, including things I've thought of that could be the source/contributing to the problem (again, I really have no idea what I'm talking about when it comes to true geek know-how):
- It's a rMBP 15" w/16GB RAM
- When I formatted the HD, I wiped out everything. Yes, obviously there was enough on there for the laptop to launch into Internet Recovery, but I'm thinking that was all that was left. When I've been trying to think of why there's nobody online with this issue, something that's popped into my head is that anyone who knows what Disk Utility does is probably savvy enough (when not sleep-deprived) to not use it to format their HD, or at least to heed to the plenty of "Don't click yes, tardums" warnings that I'm sure popped up as I zoomed by them. And I can't think of many other ways for grandma-level Mac users to wipe their HD, so the lack of online info would make sense.
- This was a couple months back, and I can't remember precisely the OS version when all this went down. I'm certain it was ML since I think my rMBP shipped with 10.8.0 (if not 10.8.1, if any did), but it could have been anything between 10.8.0 and 10.8.2. I'm pretty sure it wasn't 10.8.0 since I remember updating to 10.8.1 very soon after purchasing the laptop over the summer, but again, not certain.
Alright, that's it. I'm sure this post doesn't meet forum standards for plethora of reasons, but I'm a poor little private liberal arts university student who is desolate now that his $3,000 laptop isn't getting top-notch battery life, so mods, please dig deep in your hearts and don't delete. Thanks, yous da best.

There were a number of posts from folks with various models about a downgrade in battery life after an upgrade to Mountain Lion - so you aren't alone. However, since you're still under warranty, I would take the machine to your local Apple Store or an AASP and have them diagnose the problem. Could be that your battery just isn't up to par (and I'm assuming that you've all updates installed?)...
Good luck,

Your Battery Life after Lumia 800 Update

Hi,
I recently updated my Lumia 800 to firmware (1600.24838106.11500) and my battery life is much much better. However, I am still not seeing an expected fixed full charge of ~ 1502mAh, which it had before the update. Nokia says it may be an issue with the phone but before I send it back could any else confirm that post update they can get a max capacity charge reading in the 1500mAh's? Could there still be a little more battery charge a firmware update could tap into for all of us or is my battery weakened by pre-update battery management? My battery at the moment polls:
1) Battery Saver Life remaining around 1day 9hours.
2) Battery Status Full Charge Capacity varies between ~1350 & 1420 mAh.
3) Charging using approved Nokia Lumia 800 chargers.
3) Three charging cycles completed.
Cheers for the help.

After the update and a hard reset;
The max battery ranges between 1322 and 1478
For the 1st few days I was getting about 26hrs out of it so quite a leap from 6-9hrs but this morning the phone was dead after 16hrs - with most of that time just on standby.
Plugged in the charger and there's a battery charging image but after 15 mins I still can't turn the phone on to make a call (with charger in).
During this time my Blackberry 8520 was charged up on Saturday and the battery power shows 3 bars left out of 5.
The Lumia looks really nice but I think it's covering up internal outdated junk and the only thing that's keeping it selling is smoke and mirrors marketing.
335 hrs standby time - nearly 2 weeks!!!
55 hrs of music playback - over 2 days!!!!
It's like they plucked the numbers out of the sky... "this will sell it"!
My phone is now coming up to 2 months old and all this "there's a patch to fix it" has proved nonsense. Sure they've increased it a little but I'm sure I could have got more life out of it by setting the brightness to low myself.

X200 Windows7 Battery Life Problem

Hi, I have an X200 and recently installed Windows7 beta 7000 32bit. Even after getting all devices to work and installing Lenovo drivers where possible, my battery life time never got better than about 60% of the batterylife time I had on vista.
6 cell battery
- around 6hrs on vista
- less than 4hrs on Win7
Today I installed Windows7 Build 7057 64bit and after installing all the drivers, all devices are working properly, but still the same really bad battery life!
By now I really got used to Win7 user interface and improvements, I never want to switch back..... has anyone else problems like that? Any suggestions?
Thanks,
senorm

I've got an x200. I interchange two drives in it, one personal and one for work. Both are Win7 64. One is upgraded from Vista Ultimate, one is a clean install. The battery is a 9 cell, and performs about the same on both. I'm using the Lenovo Power Management on both.
I've not noticed a significant drop off of power, but what it's not perfect. Whenever the machine goes to sleep, whatever power management settings are in effect are frozen after that, until I reboot the machine. I thn again have control of the power settings until the machine again sleeps.
For example, I like running on power saver. On a clean start, with power connected, the screen is bright, and the processor is running at a higher rate. If I sleep the machine and disconnect from power, went it reawakens, it behaves as if it is still connected to power - it does not drop to the battery settings.
If I reboot at that point, then I have control of the power settings again, and the machine is on battery seetings (assuming I did not reconnect the power.) Everything functions as expected until the machine sleeps.
Given that Windows 7 is beta, and Lenovo's drivers aren't optimized for Windows 7, I'm very pleased that battery power works as well as it does. I've whined in this forum that Lenovo should be providing beta power management drivers, but the reality is at this point things work farily well.
I recommend patience and tweaking
I'm looking forward to the Win 7 RC, hopefully we'll see more Lenovo drivers then.

Battery life diminishing rapidly! help!?

i have a macbook pro OS X 10.4.11 purchased august of 2006 with 309 cycles on it. the battery life in the last month has dimished rapidly in the last 3 weeks, like really rapidly, and now i can barely get 30 minutes of life out of the computer on the battery, as opposed to the 2 hours i was getting a month ago.
what should i do? is 309 too many cycles for apple to help me out? what are the terms for getting a new battery? how do i maintain good battery life? is it better to keep it plugged in AC as much as possible? is there ANY way to make my battery life longer??? help!!

With the number of cycles you have logged, your capacity is not surprising. It is also too large for Apple to offer a replacement. A friend had the same issue, with a computer roughly the same age, and was classified as a "heavy battery user".
The best thing to do is buy a new battery, and start doing regular calibration of the battery to catch the loss of capacity sooner. To reduce the number of cycles you may want to plug in when possible, but do use the battery, as they prefer to have their electrons moved.
I, for example, leave my MBP plugged in at home, but run on battery for the most part at work. If giving a presentation I will plug the computer in, as I will if the battery gets below 50%. After 6 months I have 24 complete cycles on my battery.

N95 Updated software causing Battery life issues

Hi
Can anyone help point me in the right direction?
I Updated my software on my N95 (silver) to V13.0.003 but since doing so the battery life has suffered,it hardly lasts half a day just on standby, where as before I'd get 2 days at least. Bluetooth is turned off Wlan searching is off there is nothing running except Standby mode.
I've also tried a different battery, and get the same results.
Any ideas?

N95 Silver, I guess is the N95-1 or 3, both have newer firmware versions.
For N95-1 (RM-159) the last version is 30.0.015 and for the N95-3 is the 20.0.something. Both versions improves a lot the battery life and speed of the devices.
Check your last version with Nokia Software Updater.
Don't forget to make a backup of all your data before updating.
Remember that not all versions are available for all the product codes.
Cheers!

Problems with ipod battery life AND new software

First of all, I'm not 100% sure if my ipod is fifth generation... it's a 30 GB and I've had it since December 2006. This just seemed to be the only category it fit into.
But here we go: I have two major problems with my ipod that have arisen in only a period of a couple days.
First of all, my battery life suddenly got REALLY REALLY bad. I know there are already a bunch of threads with people complaining about their battery life, but mine is much worse. The battery life did progressively get a little worse over the past few weeks, but it was nothing major. But I turned my ipod on the other day, RIGHT after fully charging it, mind you, and within 2-3 minutes the battery was halfway discharged and in about 5 minutes it was almost dead.
And a couple of times, I had my ipod plugged into my iBook to charge, and the iBook went into sleep mode because I left it alone for a while. But after a couple hours I came back and the battery level was LOWER than when I plugged it in!!!! What's going on with this thing?
And then to make matters worse, I finally broke down and downloaded the new ipod software the other day (sorry I can't remember the version, but it's the most recent). Everything seemed OK until I turned on my ipod the next day. With the old software, when I would select "Music>" and then "Artists>" it would go to the list of artists like it's SUPPOSED to.
But now, when I select "Artists>" it then goes to a list entitled "Artists" and my ONLY option is "All>". If I click "All>" then it takes me to a second list called "All Albums" and my only option again is "All>". When I click it again, it takes me to a list called "All Songs" with NOTHING in it. At first, I was afraid the update had deleted all the music off my ipod, but I plugged it back into my computer and according to iTunes, everything was still there as if nothing had happened.
Is there anything I can do to remedy either of these problems? I am so frustrated with this thing, considering both of these things happened rather suddenly and the fact that my ipod is not even a year old and it's not like I've been abusing it or anything.

I've had both exact problems (listed below) within days of each other just like you. This is extremely effing frustrating and it appears Apple isn't doing sh|t about it.
Problem 1: Battery constantly discharges even when ipod is turned off.
Problem 2: After upgrading firmware to 1.2.2, all my content (songs, podcasts, everything) was gone.
I'm glad to say I was able to fix problem 2 after reading about reverting back to version 1.2.1. There are instructions in this forum on how to do it. If you are like me, you'll have to download the 1.2.1 files from Apple's website because they were no longer on my computer.
This dieing/dead battery problem is a major effing pain in the a$$. Like you say, the effing thing is dead after minutes. The only way it can be used for any length of time is to leave it plugged in to a charger.
No one seems to have a solution which is even more upsetting than the problem. Hey Apple, I want my money back!

DPI vs HiDPI on battery life

I know this may greatly vary from usage to usage due to how much/frequent scaling takes place in HiDPI depending on the applications used but I would like to hear your personal accounts in this regard. Please kindly state:
how much battery life you are getting on DPI vs HiDPI
what applications you are using and your resolution setting
your specific rMBP (year and model)
your specific OS X including its current version

I did some experiments with the coconut battery application. I tried a webpage that does not normally cause a stutter problem and a problematic web page. I choose an Apple Support Community webpage (Macbook Pro Retina 13" late 2013 (Haswell) UI Lag) for the former and continuously scrolled up and down. For the latter webpage, I choose the following one (http://www.traveltheroad.com/store/travel-the-road-expedition-journal) that is notorious in the above-mentioned thread and also continuously scrolled up and down. I must note that I have Clcktoplugin 3.0 installed and therefore the embedded video was neither playing nor even ready to play due to the said plug-in which provides the option of playing the video in HTML 480p and 720p as well as Flash. I may later run the test while playing the video at 720p HTML and flash as well without scrolling in both pages later. The screen brightness was at the second level and the only open application during the test was Mail and Coconut Battery. My Mac is Late 2013 Haswell rMBP mid-tier model with Iris graphics. OS X version is 10.10.1:
Scrolling the Apple Support Page:
1280 x 800 normal DPI : 9.5 watts          1440 x 900 normal DPI : 10.1 watts          1680 x 1050 normal DPI : 10 watts
1280 x 800 high DPI     : 11.3 watts        1440 x 900 high DPI     : 13.5 watts           1680 x 1050 normal DPI : 16.2 watts
Scrolling the problematic webpage without playing the video:
1280 x 800 normal DPI : 20.7 watts         1440 x 900 normal DPI : 22.9 watts          1680 x 1050 normal DPI : 25.2 watts
1280 x 800 high DPI     : 36 watts            1440 x 900 high DPI     : 35.9 watts           1680 x 1050 normal DPI : 36.8 watts
