Do I have a battery issue?

Hello.
I got my MacBook on Monday and I'm starting to notice something when I check-up on my battery.
It came reading "Capacity: 5200."
Today since 11 p.m. it was 5091.
Then from 2-3 p.m. it now reads 5001.
I dont know what the problem is. I charged it full without using it the first day and I let it stay without the plug for 2 hours after I charged it. Any ideas or thoughts? I did calibrate it as well. It's just too strange.

Hi,
My battery was charging well for the first three weeks of use. i could get maybe 3 hours or more out of it. Then suddenly about 2 weeks ago, while working, it just shut off without warning at 15%. I charged it full then the same thing happened at 33%!!! Now my mAh reads 1090... Gosh this is annoying. Now when it is almost fully charged, the light shifts from green to red. I can now only get 1 hour from a fully charged battery. I did try PMU reset and calibrating the battery to no avail...
depressed!

They MAY repair it
They WILL charge you
How much ,no idea

I have a battery issue that nobody experience yet.

I have a battery issue that nobody experience yet. I already know that people replace their battery when it can't hold its charge anymore. My point is when I charge my device it keeps on showing that fully charged battery icon at 53%. I thought Apple said it suppose to be at 80% when your device can't charge beyond 80%? After that it keeps on showing it at 43, 46, 50, and 63 percent. Everyday it keeps on multiplying. Is this the end for my iPod touch 4G? Do I have no other choice but to replace my battery? I don't want to mail it to Apple. They charge you more than $70+ for repairs. I could easily buy myself another iPod touch 4G with that money.
This is not the end to my question. Every time it shows that fully charge battery icon it quickly goes away after a minute or 2. My battery charges after that. If I keep on waiting for that fully charged icon to disappear ever single time and use that to charge my device constantly would my battery damage in anyway? Basically if I keep my charger plugged into my device until it reaches 100% ignoring the fully charged icon. Will my battery damage if I ignore that?
If I do replace my battery what temperature do I need to have the heat gun at anyways? I'm using an iPod touch 4G on 5.0.1. I tried to contact Apple for support, but I couldn't find their email address.

The iPod touch does not have battery percentage, so how are you gauging this? If the iPod is jailbroken that is more than likely the source of your problems, and either we nor Apple can offer any support or service for jailbroken devices.

Hard drive died, but do i have a battery issue also?

Hello,
Well, my powerbook has been acting funny for the last few months and I think it finally died today. I've been doing weekly bootable backups on a smartdisk firelite 100GB external hard drive. Yesterday my computer was really slow, so today I updated the backup. Afterwards, I tried running disk repair in the disk utility on my internal hard drive, but it froze while doing that and I was forced to hit the kill switch. When I started it again I got the mini-folder with a blinking question mark. Luckily, I think the bootable backup works (although I've had issues with that drive mounting in the past) and for now it looks like I have all my files and applications. I tried running disk repair on the internal hard drive by got the error message: "invalid B-tree node size, volume check failed, underlying task reported failure on exit (-9972)".
My question though is about how HOT my powerbook had been running lately. I've been using a notebook cooler with a fan, but it's still very hot to the touch after a while above the keyboard and sometimes I've noticed it's hot on the lower right side (under my left wrist). The adapter on the AC plug/cord setup gets hot also. I'm wondering if the heat was because the hard drive was dying, OR if the hard drive died because of the heat? (Note: I checked my battery serial number a long time ago and it wasn't part of the mac recall.)
I want to get a new hard drive to install (at BestBuy or some other place I guess). I'll look around on the list for recommendations, but I'm open to suggestions. I don't know if it's worth wiping the hard drive I have now and restoring it from the backup, or just assume it's dead. I don't want to get a new hard drive and find out I have a battery overheating issue instead.
Thanks for your help!

Lisa:
Before you purchase and install a new HDD, just hold a minute.
Great that you have a bootable backup of your HDD. Good thinking. Are you able to boot the computer from the external firewire HDD? (From a cold start, turn on external HDD, hit computer power button and immediately after chime hold down Option key. Select external HDD in screen and click right pointing arrow.)
When you ran Disk Utility, did you notice the S.M.A.R.T Status? If it says Verified, there is still hope. If it says failing, we'll need to find you a new HDD.
+"invalid B-tree node size, volume check failed, underlying task reported failure on exit (-9972)".+
This indicates serious directory issues for which you will need a utility like Disk Warrior, Tech Tool Pro, or DriveGenius. Take a look at Disk Utility reports "Underlying task reported failure" when repairing a volume for details about the issue.
One of the above utilities has a good chance of repairing the directories. However, there is an even chance that the drive may be too damaged to be repaired. However, you won't know that until after you have run one of those utilities.
Your computer will support a 2.5" (P)ATA/IDE HDD up to 160 GB. Here are some HDDs that will work for you at OWC. If you are handy with a screw driver and have the time and patience you can probably install it yourself using these step by step directions from ifixit. If you need to install a new HDD, and think you would like to try it yourself, post back for additional tips.
Cheers.

Does my Xperia Z2 have a battery issue?

Hi,
I am finding that the phone is losing battery faster than I would expect it to based on reviews that I read before purchasing.
Some examples:
- when browsing on wifi, it drops 1% in approx four minutes
- by 22:30 typically it is at ~50% with limited use (browsing on the tube for about an hour, sporadic texts through the day, Spotify during journeys) since I woke up and took it off charge at 8.30
- by midnight it tends to be down to about 30%
- this has been pretty consistent since getting the phone mid-May
- I've got Facebook and a few email accounts on push but apart from that I'm not gaming or using tons of apps / any lock screen widgets
- as of today my system update es are all up to date
How does this fit with what you guys are getting?
Thanks,
Phil

Hi Phil,
I get 4 days out of my Z2; here's my setup:
Stamina mode on, Low-battery mode off, location-based wifi on. I have 4 apps active in Stamina standby; Falcon Pro (Twitter app), Gmail, gReader Pro (RSS reader), SmartWatch 2 (!)
No widgets on my screens apart from a battery monitor, the BBC weather app & PowerAmp 4x2 (music player).
Now here's the one you're not going to like. Disabled Apps - Facebook, Google+ and Walkman
Two of those apps I found to be the most data-instense; Facebook even sends & receieves data even if you're not signed in! (They assume that you're accepted the terms & conditions by installing it, and that allows them to tracks your phone via its IMEI number... Honest). Google+ is just ... argh. I couldn't believe how much that kept wanting data. And Walkman? I wanted a gapless player so I use PowerAmp instead.
I am on Facebook, I just use a 3rd party client instead.

Possible cure for battery issues

hi
first of all i dont own the device yet
i am user of 5530,5800,n8,c7,701
i was looking farword to bring in my hands the first nokia wp7 but due to features missing and (in my opinion) little overpriced at the moment(as sim free) i will wait for the next nokia wp7
but being for a while in nokia forums i deside to write this atricle with my opinion about the battery issue (IF IT IS) with the 800
after reading many users facing problem with battery in different revious and forums about my N9 last longer or my N8 etc i deside to do a test with my current in use 701(1300milliamber battery and the brightness screen that nokia offers right now)
i left all day the phone connected to 3g and gprs data with about 5 min calls couple of textsand little browsing fmobi,little use the default browser,little use apps which connects to internet ...all these for about 1,5 - 2 hrs
it did last about 12 hrs same as some users with the lumia
Now if you dont belive me TRY THE SAME TEST BY YOUR SELFS
what i have understand (as i dont own the device) is that perhaps by default or out of the box (and especially the branded phones from the providers) is that featurs like wifi or data, nokia account, market place bing etc must be ON
if was the same issue with my 701 it will not go too far of course
what nokia possible can do is to do a frimware update which in start up or rebooting the phone....dark them,wifi,data,bluetooth,internet connection should be off by default like in symbian
i am sure the upcoming new customers will not have future complains
but i belive this is important as some poeple dont have the knowlege to do all these to turn off manual, especially in a new UI that they are using first time (wp7) and of course having a new phone most of them especially the non experts can think the battery drains so easy if all are ON
******* or at least nokia should make it like symbian to turn off automatic after closing apps,face,twitter,email etc
thanks for your time reading
for me after my Xmas bonus(if any lol) i will go for a windows phone(sim unlocked)either if nokia or other brand
of course i can wait for the next nokia model not because of the battery issue but i prefer in windows phone 7 bigger screen
thanks again

I must agree with your thinking...
When I first got my C7, battery wasn't lasting a day...
And the reasons was the ones you said...
e-mail was keeping data on, WiFi was always looking for a connexion
I won't say that the Lumia 800 can't have any battery issues, but first of all, it's our use that kill off the bettery...
Setting e-mil to work only once per hour, setting WiFi off when not used...
Only those 2 option give a bette life to the battery...

Forget the battery issue for a moment,

I think the battery issue will be fixed, I think there are many reasons for it, I'm not going to speculate. What I would like to know is if you can forget the battery issue for a moment, What do you think of the 4S itself, the camera, mirroring onto apple tv etc...have you been happy with the phone and its functions and if it didn't have a battery issue right now would you reccomend it? I'm thinking about buying two of them and that is a substantial investment, just wondering if it's everything its cracked up to be...Thanks!

Yeah it's a good phone. It's my first iPhone. I came from a Droid Bionic, so I am use to no battery life. I usually charge it at my desk at work and it last all night until I get back to work. I listen to music on my car, so it's tied to the USB input to my car, so I don't really have an issue with the battery.
The camera is really good. For a point and click, it's fast and the pictures are clear. They only thing I run into, which is on every phone camera is smudges on the lense.
It took a lot of getting use to going from the Bionic 4.3" screen to the 3.5" screen.
I don't have the Aple TV set up, so I can't answer that.
What I like about Apple products? They work. Very simply, they just work.

Ipod touch 4g cracked screen w/ warranty . battery issue too

hey everyone
i just came back from my long vacation, while on vacation my little 3 year old sister dropped my ipod (long story) but yeah now my ipod touch 4g 8gb is screen is cracked. the ipod still have warranty until january. is it possible to get a replacement/repair from apple?
also on the very same ipod i have some battery issue, it takes me roughly almost 2 hours to charge my battery full and it drains like crazy! maybe 2 hours of usage and its done.
thanks!

An iPod that has been dropped such that it cracked the screen will no longer be under warranty. You can take the iPod to an Apple Store and hope - it's been reported that in some cases the technician has been allowed to replace the iPod under warranty even though Apple is not obligated to do so for user abuse - but you may well have to pay the replacement charge.
Regards.

IPhone 5 still using 6.0.1 because of battery issues. Now hearing about battery issues w/ 6.1, too. When does anyone think it'll be safe to upgrade to 6.1

Any time you want. I've upgraded to 6.1 the day it came out and have no battery issue.

Battery issue after bicycle accident

Hey all,
A few weeks ago I fell with my bike and my z1 compact took the hit with all my body weight. The backside took the major hit and looks really bad, and from the side you can see the phone being bent. However, the phone has been working perfectly for over 1 month which is just incredible after that big hit. Sadly my phone has started showing signs of the hit lately, usually the phone just restart itselfs, or freeze so I need to press the red button or power/volume up. But during the last couple of days the phone is unresponsive. Its 100% dead, you cant charge it or anything. But suddenly you try to start it and it comes to life from nowhere, always with 1% battery left.
From my untechnical experience, it sounds like we have a battery issue here? Is there anything I can try or do myself before sending it away for a costly replair?
Best regards
// Johan (Sweden)

You could if you feel up to it remove the back glass and replace this yourself at a fraction of the cost - Whilst the back is off you can check the battery connection and the board for signs of damage
I would suspect not the battery itself (if Li-Ion would get punctured his phone would be already destroyed) but from broken paths on the motherboard. Anyway without inspection it is impossible to get any futher.

Battery issue LoadCycle count increases without charging , MacBook Pro Retina 2012?

Hi
i have the feeling that i have a battery issue.
It looks like that the battery cells are in one region defekt.
Once i cross about 30% last charge it starts draining very fast within 10-15 Minutes the MacBook switches off.
In order to proove this i have written a small script in order monitor the battery and some other counters.
And here is realized anothe interesting topic.
The Load Cycle Count can increase even if you dont charge !!
Below you see that the LoadCycle Count increased from 373 to 374 even if i didnt charge.
Any ideas on that. Or does anyone have the same issue ?

tesme33,
have you tried resetting your MacBook Pro’s System Management Controller, to see if that affects its energy consumption?
When I run
ioreg -n AppleSmartBattery -r | grep -i CycleCount
on my MacBook Pro, I get two different output lines. You might want to adjust that part of the CYCLECOUNT assignment to have
ioreg -n AppleSmartBattery -r | grep '"CycleCount"'
instead, to ensure that that returns only the intended single line.

Macbook battery issue - Dies quickly, jumps to 0%! Details...

Hi all,
It looks like lots of others have had battery issues with their Macbooks, so I'm going to try and give a specific explanation of the problem with my Macbook to see if A) I should replace the battery, or B) There is some sort of problem that I can fix somehow, or C) If I need to take it in to be looked at.
I've owned the 13" Intel Macbook for about 20 months and it currently runs OS X 10.4.10.
If it is charged up to 100%, it will generally run on battery for a short amount of time, usually from 20-30 minutes, and then shut off, as if the battery were empty, with no low battery warning. Oftentimes, the battery percentage is at anywhere from 20% to 40% when it shuts down.
When I plug the magsafe back in, it usually sits at 0% for a while, and then acts like it is charging until it eventually reaches 100%, although it seems like it would be charging too fast to have actually jumped from 0 to 100%.
It's a very peculiar problem. On a side note, I installed a 1GB RAM upgrade (from the previous 512) which was purchased from someone else who owned an intel macbook who was upgrading his own RAM again, just in case that makes any difference at all.
Thanks for any and all help!

BTW, I've allready reset the SMC sevveral times
http://support.apple.com/kb/HT3964
I've also calibrated the battery several times.

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.
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!

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..

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

I have an iPod Nano that is synced to my mac, but it is sent in for the battery issue. Anyway, I have bought a 2nd gerneration Ipod touch and I want to now sync it to my mac, but it does not show up in the left menu bar. Please help. Thanks All!

I have a battery and Memory issue - late macbook pro 2011

Macbook Pro 13" Late 2011 Model
Battery Issue
After upgrading to Lion, my batter life is 3 hours after full charge. It was 7-8 hours in leopard.
Hoping this is a common issue and someone has a quick solution.
Memory Issue
I had 4GB Ram and found it would run to virtually nothing and not free any inactive RAM. I though the solution to this was to buy more RAM, which I did.
I now have 8GB RAM and it agains runs to virtually nothing on non labour intensive software like safari or mail. It doesnt free up any RAM when it reaches a certain point. Instead it freezes and I'm forced to restart the computer. I use Final Cut Pro X and Photoshop/Illustrator fairly regualry. I'm assuming the RAM is is used with those but even when these are closed the RAM is low.
Any ideas?
Cheers

You should take your Mac to an official apple retail store, as it is not common to have these problems regarding battery and memory.

Do I have a battery issue?
