Is Firmware 5A347 helping YOUR 3G battery life?

When I got my 16 GB iPhone 3G on launch day, my battery lasted all of 5 hours with a mix of calls/internet, txt, etc. I didn't adjust the default settings(all services ON), but I set out to figure out how to stretch battery time or decide I need to return it for such poor battery life and stay with Verizon.
Thanks to these forums, I:
Did a restore via iTunes from 5A345 to 5A347.
Turned off the 3G
Turned off WifI(will use it when needed)
Turned off Location Services (will use it when needed)
Press the sleep button when I'm doing using it for the moment
Battery time increased to 12 hours mix of talk/web/standby
So, I looked and my usage was roughly 5.5 hours on a day I had 30 minutes of chat, no browsing, etc. So I kept looking for what was using my phone....
Deleted my "Where" app and some freebie game apps...left the REMOTE app and Bank of America app on the iPhone. I left my hardware settings as noted above.
Battery Time now sits at a usage of 1.25 hours, Standby of 17.75 hours, and a battery meter still at roughly 85 percent.
I have the brightness at 30% and on auto-bright....the auto-lock set for 1 minute....the fetch email on for 1 Hour, PUSH is on(I use and LOVE MobileME).
I'm going to run this cycle until the phone shuts off. The stretch from 5 hours to currently 18+ is incredulous...I'll report back tomorrow.

I haven't really had any major problems with battery life. Though at this point in the day I would usually see the battery depleted somewhat. However, since I've installed 347 it appears that my battery life is better. Today my battery shows as full and it's been on battery since 9 a.m. eastern time this morning. I've done a little web browsing, sent out a few SMS's, added some contacts, and I'm monitoring 4 email accounts on it (two push). I have 3G enabled, BT enabled, WiFi enabled (and connected to a network).
This is very preliminary as I only looked when I saw this thread topic. It may take a few days to verify.
BTW, I restored because I had trouble with my app store apps loading.. Not because of battery life..

Help, iphone 3gs battery life go down in 3h abroad

Hi everyone, my iphone 3gs battery in italy is perfectly normal, when i go for example in spain or in greece ( no different voltage) the phone is 100% in the morning but after 4 h without call, message, wifi or 3g activated run out at all.
I try to close all the app, close all tab of safari, roaming is off for the data, i clear history and i reset it....
I dont know what else i could do...
Help plese! Thanks

Update of the firmware?

That is NOT what you said previously. You said: "I try to close all the app, close all tab of safari, roaming is off for the data" We are NOT psychic. Your original statement does NOT indicate that you have 3g off.
If the phone is unable to lock onto the preferred provider you set in manual mode, it will be constantly searching for the carrier signal. This will drastically reduce battery life. If you are out of range of the carrier you want to use, put the phone in airplane mode.

Treo 680 Camera update released by Palm helps greatly with battery life

If you have not installed this update yet, it is HIGHLY recommended that you do so. It is located:
http://www.palm.com/us/support/downloads/treo/680cameraupdate.html
And is for *ALL* Treo 680 users.
Post relates to: Treo 700p (Sprint)

Folks from Palm do monitor THESE forums especially, and there is a way that us moderators can bring things to their attention here now (unlike the older forums).
The problem here, as I see it (and yes, I have both my 700p and a 680) is that in order to make a thin, GSM phone to sell for $199, they used a smaller battery:
1800mAh(top) vs 1200mAh(bottom) battery, which translates into less battery life (33% with the basic same underlying functionality). And for folks that use the heck out of them (points to self) this will not be enough. So... I charge more often, and have a spare that I keep in the cradle, charged. And I do the meat of my email on the 700p (which also gets charged daily and on heavy email days twice a day; or plugged into the USB port, see tips below).
Palm has given tips on extending this as much as possible (turn off BT, minimal timeout, etc, etc) but basically its a tiny battery. Add to this fact that GSM radios tend to draw more power and UGH... bad battery life. Folks that use the heck out of a phone will not be happy (nor would they be happy if they were doing the same things on say, the new sexy tiny BLahzor or whatever its called, and yes.... That battery is even smaller).
I'd also like to note that Cingular (or any carrier) won't sell a product that didn't meet their minimum requirements, ie talk time, standby, etc.
There is a third party company making a larger battery, and I'd expect as battery technology gets better we'll see replacements that work even better. However I doubt you'll see a tiny battery on a used a lot device ever have "good" battery life.
One final set tips: get a HS cable when you're near your computer and plug in the phone... even a quick 30 min trickle charge will keep you going longer. Get a car charger, or an extra battery and cradle. If you are using Email, set the auto sync frequency longer than 5 mins: 15 mins vs 5 means that your radio is on up to 66% less with respect to data traffic.
To close, I'm sure if Palm discovers anything they can do to extend the battery life on the 680's, they will pass that along....

Problems with your iphone4 battery life? READ HERE!!!!

I will make this short and simple as I too have been experiencing battery problems with my iphone4 since I upgraded to 4.0.1
Now here is what I THINK is going on, I believe there is a BUG in the wifi software in IOS that tends to drain the battery at a rate of 5% every 10 to 15 minutes or so if you are using the phone for surfing. And if you are not doing any internet surfing at all, it still drops the battery at a similar rate.
Sadly what I have found out is that this doesn't stop even when the phone is on standby. Two hours of my phone just sitting there, I lose about 5% plus. So if I leave wifi on and go to bed, my phone will lose close to 25% of battery over night. However once wifi is OFF, the phone will only lose about 2 to 3% over night. I'll say that's a HUGE difference.
What I also have noticed is that it doesn't matter if I have notifications & push ON or OFF, the battery still gets drained at the same rate as long as wifi is ON.
Once I have realized the culprit, I went from getting a mere 4 to 5 hours of usage to 8 to 9 hours.
So, I suggest that you all only turn wifi on when you NEED it. Once you no longer need it, just shut it off. This is what we have to do until apple fix this problem because it seems like having wifi ON is constantly working the wifi antenna even when the user is not using the wifi connection at all. Apple claims a whopping "up to 10 hours" of internet surfing over wifi. How can that be when my phone will lose over 30% of battery in 10 hours just on standby with wifi ON?
By the way, all my tests were done with my phone on EDGE only.
If you have done this and it worked for you, drop a line here

Note that the battery drain can be of many features you are using in idle or in use. Whether you notice it or not, it'll drain every 10 to 15 minutes on idle based on the several features enabled:
* Push Notifications with 10, 15, 20 apps that run it
* WiFi, cellular, 3G
* Bluetooth active or idle
* Mail set to Push or Fetch by Minutes
* Applications left to run in the background
Nearly every iOS4 app will add the Fast App Switch, File Transfer Services, and Background Location. If you are not using any of these apps, it's recommended to close them down. Whether it's iOS3 or iOS4 apps, they will slowly drain the power through the RAM processor.
If you run a system info application, it'll state how much RAM you are currently occupying with all your multitask apps running. The more RAM used, the more battery power is drained. You can increase battery life by doing the following:
* Settings-Push Notifications-Turn off any application's push that doesn't work anyways or is bothersome to receive. Setting Notifications to OFF in general will repeat a consistent popup to enable it again.
* Settings-Mail-Push-OFF, Fetch-Hourly, Advanced-Schedule to Fetch
* Close all running applications not in use that sends notifications later. They are running in the background draining resources.
* Follow Apple's guidelines on improving battery life such as setting brightness to mid range and automatic or turning off unused features.

How is your iPhone battery Life holding up with the Watch paired ?

I haven't received my watch yet, But my wife got her watch and says her phone died much faster today. Its understandable since the pull on the battery is greater with Bluetooth on all day. Just curious to see what the community is experiencing.

me too.
And last night, Im the only one did not check phone all the time among my friends.
My life is back

Leave phone connected during work: Does this help or hurt battery life?

If draining and charging ultimately wears battery down, could i leave it plugged to charger during the day at my desk? This would seem to cut down charging cycles, but maybe it introduces other problems.

Won't harm it all all, it stops charging when it is full.
Your lithium polymer battery does need exercise though, make sure to do a full charge cycle at least once per month.

Save and Protect your iPad Device: How to Save and Prolong the battery life of your new ipad

Please, as you read add more answers to this on how to prolong and save your ipad battery life. Thank you
Saving the battery life of your iPad
1.Keep Your iDevice Out of the Sun
Whatever you do, don’t leave your iPhone or iPod sitting in a hot car—heat kills batteries faster than any other factor, and your device that used to keep a charge for hours will eventually barely hold a charge, and you’ll have to pay Apple to get it replaced. The same thing holds true for any really hot environment: try and store your device in a cool place.
Reduce the Screen Brightness
If you keep the screen at maximum brightness all the time, you’re wasting a lot of battery life—and the screens these days are so bright anyway that you don’t really need to, especially at night. Head into Settings -> Brightness & Wallpaper to adjust the default level of brightness, which you can probably keep as low as 30% most of the time.
2. Make Sure the Screen Locks Quickly
Even if you’ve adjusted the screen brightness, there’s still no substitute for having it turn off quickly when you’re not using it. Head into General -> Auto-Lock to set the screen lock to happen as quickly as your device will let you. This makes a big difference if you are always picking up your phone and putting it back into your pocket without turning the display off.
3. Use Airplane Mode When You Don’t Need Internet (iPad/iPhone)
If you’re busy spending the next 8 hours playing Angry Birds, there might not be a good reason to have internet access, so you can consider using Airplane Mode, which turns off both Wi-Fi and the regular wireless radio. Of course, this will prevent phone calls if you’re on an iPhone—but if you’re busy with Angry Birds you probably don’t want the interruption anyway.
4. The more important reason to use Airplane Mode is when you’re mobile in an area with a really spotty connection—because the iPhone or iPad will try to stay connected at all times, it’s going to be constantly searching for a connection, which can drain your battery. Head into Settings and flip the Airplane Mode switch right up at the top of the screen.
Use Wi-Fi Instead of 3G if Possible
According to Apple, the iPad will get 10 hours of battery life under regular use with Wi-Fi enabled, but will only get 9 hours using 3G—the iPhone gets 6 for 3G and 10 for Wi-Fi. Of course, if you’re heavily using the Wi-Fi, you’ll still be draining the battery—the point is under similar workloads, Wi-Fi is better than 3G for battery life.
You can enable Wi-Fi under Settings -> Wi-Fi, and then pick the network you’d like to connect to.
5. Reduce or Eliminate Mail & Calendar Checking
If you’ve got a bunch of email, calendar, or contact accounts configured, and they are all being checked and downloading email on a regular basis, you’ll be draining the battery an awful lot faster than you need to.
Head into Settings -> Mail, Contacts, Calendars -> Fetch New Data and change the setting to the least frequent check possible. If you don’t use it often, you can just turn Push off entirely and then manually check when you need to.
6. Reduce or Eliminate Push Notifications
Do you really need notifications from Twitter or whatever other apps you’re running? You can turn these off one-by-one, or turn off Push entirely by heading into Settings -> Notifications, and save a bit of extra battery life since your device won’t be pulling in data for those applications anymore.
7. Reduce or Eliminate System Sounds
This one is probably a little silly, but if you really don’t care for the system sounds you can save a small amount of battery life by removing the sounds. A very, very small amount, most likely. Head into Settings -> General -> Sounds to change them.
8. Disable Location Services
If you don’t really need the location services, you can disable them to save some battery life. Head into Settings -> General and flip the Location Services setting to off.
9. Disable Bluetooth If You Don’t Need It
If you don’t use a Bluetooth headset or keyboard, you should keep the Bluetooth radio disabled to save some extra battery life. Head into Settings -> General -> Bluetooth to flip it on or off.
10. Disable Vibrate Feature in Games
If you’ve got a game that uses the vibrate feature, you can turn that off to save some battery life. This mostly matters if the game heavily uses it, and you’ll need to change the setting for the game. As a side note, and it should go without saying, if you’re running really intensive video games, they will kill your battery very quickly.
11. Charge and Discharge Your Battery Regularly
Your iDevice needs to be fully discharged and recharged at least once a month to operate at maximum efficiency and keep the battery from dying. You’ll also want to make sure that you don’t store the device with a dead battery, as that can also cause the battery to lose charge capability—when your battery dies, make sure to recharge it quickly.

Thank you all.

The reason that Apple suggests you drain and recharge your battery once a month is not because it affects the life ofthe battery. What it actually does is calibrate the battery sensor, giving you a more accurate reading.
Other than that, you done an admirable job of summarizing the Knowledge Base article:

HOW IS YOUR IPHONE 4 BATTERY LIFE ?

HEY EVERYBODY , JUST WANTED TO KNOW IF YOU GUYS WHO ARE LUCKY ENOUGH TO GET YOUR HANDS ON AN IPHONE 4 , HOW IS YOUR DEVICES BATTERY LIFE? IS ANYONE CHANGING THERE SETTINGS ? JUST TO GET SOME IMPUT FROM OTHER PEOPLE. I GET WITH MEDIUM USAGE , ABOUT CLOSE TO TWO DAYS TILL I HAVE TO CHARGE IT.....
Joey

I've noticed much better battery life with my ip4. After taking it off the charger on July 7 at 4:30 am, right now I'm at 4 hours, 46 minutes of usage and 30 hours of standby time and still have 52% of my battery left.
I don't need push so I leave that off, blue tooth is off until I need it, 3g on all the time, wi-fi on at home, I tend to close out any apps on my multi-tasking bar. Over night I didn't have it on the charger (just want to see how long I can go on a single charge with the new phone) and lost only 3% of the battery which from what I've read on these forums is normal.
I'm very pleasantly surprised by the stellar battey on this phone. I didn't really think I had battery issues with my 3gs either but the difference is quite obvious. With the 3gs, less usage and fewer hours of standy time (by the end of the day-10 pm, for example) had me at 30-40% of battery life left.
I'm quite happy with the new phone

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:

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..
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

Are apple trying to resolve battery life issue ?

Hi,
Since updating my iPhone 4 to iOS 5.1 my battery life has significantly decreased.
Like myself several other users are having the same problem with terrible battery life.
I am just wondering are apple trying to resolve this issue and if so by doing what ??

There is no way to knw what Apple is trying or what they are doing, unless they announce -which is very rare.
Most have no issue. They released 5.1 to help resolve ths issue. Try doing a forum search to see if you can get some help extending your iphones battery life.

Best way to extend battery life?

I have been using my IPAD with it being plugged in when I can. I feel this may help to prolong battery life than for the battery to charge/discharge so often. Any thoughts? Thank you!

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html

Droid Bionic Battery Life

Help! My battery life is awful. I can have a fully charged battery and within 4 hours it's at less then 30%. I would say this occurs with very light phone use - maybe 10 texts, 10 minutes of web and a check of the weather. Any suggestions on how to help? I have purchased a brand new battery, I've cleared out the cache per another discussion on this site and it doesn't appear to help.
Any other suggestions? It's ridiculous to have a smartphone and not really be able to utilize it for fear that it will die and I will need to make a call or contact someone & am not by an outlet to charge my phone.
Thanks!

If you click the Uninstall Updates, once they do, indeed, uninstall, the button then should switch to a Disable button. Your disabled apps are then moved to the bottom of your app list.
You also may want to run a system cache clear:
Power down phone
Hold volume up/down & power simultaneously until you see the Boot Mode Selection Menu
Use volume down to navigate to 'Recovery', use volume up to select
Should see screen with triangle and exclamation point next to an Android
Press volume up/down simultaneously to go into system recovery *
Use volume rocker to navigate to 'wipe cache' and use power button to select
Once finished, use volume rocker to navigate to 'reboot system now' and use power button to select
* if doesn't work:
press and hold the volume down and wait for a second or two, then press and hold the volume up and the volume down buttons for 5-6 seconds and then release
