Update of the firmware?
Thanks
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.

My iPhone 3GS battery is running down too quickly

In the last few days, my iPhone has started running down *very* quickly. I have been running iOS 6.1 for ages without any problems. Could this all of a sudden cause problems like this?
I have disabled mobile data and 3GS and just left the clock, calendar and reminders running, but this has not helped. It was 100% charged when I went to sleep last night, and when I woke up this morning it was down to 20%.
Can anyone advise me on a way to fix this please?

Really... took me all of a minute to find http://support.apple.com/kb/TS2802 which reveals:
Battery life seems short
Note: Charging with a FireWire-based power source is not supported, except on original iPhone.
Click ( www.apple.com/batteries/iphone.html) for tips on how to prolong iPhone's battery life.
Try turning iPhone off and then on again.
Connect iPhone to iTunes and restore iPhone.
If the screen shows a low-battery image, the battery is low on power and needs to charge for up to ten minutes before you can use it.
When charging iPhone, make sure to leave it charging until it is fully charged. You'll know the battery is fully charged when the battery icon in the upper-right corner of the screen looks like this .
Note: When charging using a computer, don't connect iPhone to a keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPhone is connected to a computer that's not turned on or is in sleep or standby mode, the iPhone battery may drain.

IPhone 3GS battery life iOS 6.0.1

I updated my iPhone 3GS to iOS 6.0.1 and my battery life has gotten terrible. Use to get all day off a charge not it's dead in <6 hours. Any fixes?

I have the same issue w/ my 4s. My battery life was more than acceptable running iOS 6. I updated to iOS 6.0.1 & now my battery life is HORRIBLE!!! I just charged my phone & according to the usage, ie. Time Since Last Full Charge, was fully charged, yet it only said 94%. I shut my phone off after unplugging it & when I turned it back on, the battery read 97%... ?????
There is definitely something that needs to be addressed w/ the 6.0.1 update!! Really wish I hadn't gotten it!

IPhone 3gs Battery life with 3.1 firmware

Any news regarding battery life with firmware 3.1???? I have lost at a minimum 25% after upgrading from 3.0.1 to 3.1. Have reset....the device alone and with iTunes....Need help...

I originally posted this in the wrong discussion...
Since upgrading to 3.1, it looks like the biggest battery drain is due to using PUSH with my Exchange email. I can turn off PUSH, use FETCH (even over 30 minute polling intervals) and battery life is close to 24 hours on a charge. Turning on PUSH, but not using it for email (other than my .Mac account (MobileMe), decreases the life by a couple of hours, still well beyond the normal 10 hour work day.
Turning PUSH on for 3 Exchange folders (Inbox and 2 sub folders) results in a drastic reduction in battery life. It can use over 50% charge while on standby... over a 3 hour period. I've managed this to an acceptable (8-12 hours, depending on phone calls) by limiting using Exchange rules to keep most important email to the Inbox and one sub-folder (I may eventually leave all important stuff to the Inbox) and move other stuff into different folders that I can still check on occasion.
Other PUSH activities, using apps like BeejiveIM, AP News, MLB.com, i.TV and even .Mac don't seem to affect the phones battery life too badly.
I'm wondering if Exchange w/PUSH is doing too much, besides listening for new mail and alerting on it. Could the process be simplified to only listen, alert, and mayby increment the count (not downloading headers or message bodies until one actually checks for messages... the iPhone still polls once you open a mail folder anyway).

Why is my iPhone 3GS battery life shorter in 6.0?

Since I upgraded to OS 6.0 my iPhonr 3GS runs out of battery life before the end of the day.

There are hundreds of posts regarding battery life after iOS updates.

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
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!

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

IPhone 6 battery life draining since 8.1 update

Is anyone else having problems with their iPhone 6 battery life diminishing since the latest 8.1 update? I notice I'm getting much less usage time per hour. For example, before 8.1, it would take about 3 hours of usage time to get to 70%. Now it only takes 2 and it gets worse after that. Here is a screenshot I took of the battery usage before the 8.1 update:
This is pretty normal usage timings for me (it was taken Monday, October 20th). Now, here is a screenshot from today, after starting out with 100% this morning:
As you can see, it's quite a huge difference. The weird thing is that messaging seems to take up more battery life than it used to. Yes, I do text quite a bit during the day but the frequency of this has not changed between now and October 20th. It shouldn't be using THAT much battery life. I took it to the Genius Bar yesterday to ask them about this problem and the girl told me that she saw some crashing from the Messages app in Diagnostics Information and she felt that maybe since the update, there was something causing that app to use more battery. So she suggested erasing the phone and restoring from an iCloud backup. I did this yesterday when I got home but, as you can see, the problem is no better (though there are no more crashes listed in the diagnostics information).
I have no idea what else I can do to fix this and I'm getting really tired of having to charge this twice a day now (I used to have to do this with my iPhone 5, as well). If anyone has had a similar problem, I would appreciate suggestions. And before you ask, I'm doing all of the normal battery saving tricks, like turning off background app refresh, not having it check for mail all the time (it's manual), brightness is down, I turn wifi off when not using it, I don't leave apps open, etc etc etc.
Any help would be appreciated. Thanks in advance!!!
Pooja

I turn off background refresh, mail push/fetch, and I turn off wifi and bluetooth if I'm not using them. I also minimize which apps use location services. Even when doing all of that though, the battery life became terrible on 8.1. Since updating to 8.1.1 all issues seem to have been fixed so I'm very grateful for that. I recommend anyone on 8.1 who is having issues to upgrade to 8.1.1 immediately.

Anyone having problems with there iphone 5 battery life been very poor

I have had the iphone 5 for 4 weeks now and the battery life is very very poor at first i thought it must just be how it is....was dissapointed tho from fully charged to flat in 4 hours with little use or going to bed and waking up with the battery life going down 17%!!! but then 1 day i charged it fully and it never went down for ages, over 24 hours and it still had 25% this lasted for about 4 days then all of a sudden back to been rubish, i sent it in to apple who returened it without doing a single thing (apart from scratched an dented the bottom!!) it was exactly the same ..poor.....but then last night i charged it took it off charge at 6pm (english time) and now at 00.42am the day after it still has 11%....clearly ther is a fault somewere!!! has anyone had the same experience or got any tips for me please?
cheers, Danny

Yes a lot of people are having this issue it's from the ios 6 update. Some users are reporting battery drains a lot after updating their device
There have always been a lot of battery problems posted about in these forums following each and every iOS update. Personally, I believe that the battery really isn't discharging any faster, it is just that the charging circuit is confused and needs to be reset. I always perform a setup as a new phone for major updates, for example iOS3 to iOS4, 4 to 5, 5 to 6, which should be a 'reset' for the charging system, but I do a simple update for point releases--6.0 to 6.0.1, etc. I have never had a problem with battery performance when performing the full update as new, only when I did a 'normal' update for a point release. If I perform an update with a restore from the old backup after a major update the battery problem did appear.
After every iOS point update I always do a full reset--home and on/off buttons held down until the Apple appears--three or four times over the course of a couple of days. I allow the phone to fully charge overnight every night.
This has always resulted in 'normal' battery life after one or a few reset cycles. By 'normal' I mean that a fully charged iPhone, with email and other notifications enabled and set to push, and no particular attention paid to battery conserving techniques, will discharge to about 89% over a 10 hour day. If I make a few phone calls and surf the web a bit then the level has fell to 70% or so, but unless I heavily use my iPhone 5 it doesn't drop below that point.
Prior to performing the resets the charge level would sometimes drop into the 50's or 60's or even lower in a few hours without using the iPhone. This problem 'scenario' has happened with every iPhone I have ever owned and I've owned all but the original iPhone.
As always, YMMV. I make no claims as to its usability for anyone else.

My iPhone 3GS battery loses at least 30% charge when off for at least an hour

My iPhone 3GS battery loses at least 30% charge when off for at least an hour, I took it in to an apple retail store at the end of 2010 and they told me it was fine but advised I restore and set up as a new iPhone which I did, it got better for about a month then went back to normal losing battery. I have no hardware coverage left and my specs are: iPhone 3GS 16gb IOS 4.3.3 white. I have had it since December 2009.

I'm afraid I don't. I don't know if the phone is still within warranty. I don't know which country you are in. I don't know what third party repair companies charge where you are.
Hang on - I do know one thing: if your phone is still covered by warranty - it's free!

My iphone 3gs battery drains very fast

my iphone 3gs battery drains very fast it won't last for whole day
i just uses mail application and facebook for some time
can u tell why the problem is or need to change battery

I'm having the same problem with my 3Gs. In my case it is not the apps int he background or the brightness, or wifi or email push. The folks at the apple stroe tell me that there is some software glitch that shows up every few months.
I can only get rid of it by restoring my phone as a new device. In which case I lose all of my contacts, settings and all data. VERY frustrating. I had recived two new phones (before applecare ran out) and have done the resotre several times. No one can tell me what is in that creates this probelm. I've tried differenet chargers one by one in case they are the probelm. one int he car, one in a kitchen outlet, one at my home computer (sync) and on at my office computer (non-sync).
Problem just showed up again randomly two days ago, no new apps or hardware. battery drains from full to 0 in two hours.
Apple, please fix.

My iPhone 3GS battery

My iPhone 3GS battery is very weak it can not stand more than 12 hours after a full charge

same here.. . do i need to replace the battery for a new one?

My iphone 3GS battery exploded, and made the whole phone bloated.

My iphone 3GS battery exploded, and made the whole phone bloated. I contact my local apple support and they said it is a normal case when battery is used for more than one year. Where else can I can some reasonable explanations and solution from apple about my phone. My phone cannot be used, and I have lost alot of valuable data and photos. Can I recover them? What can I do now?

If you've been using your phone as recommended, you've been syncing your data to your computer frequently, and importing any photos taken by the iPhone to your computer (or using photostream). If you havent' been doing this, then you've no one to blame for any data loss and any phone, which can be damaged, dropped, stolen or otherwixe become inoperable was NEVER meant to be a storage device.
As far as your battery is concern, is is NOT normal for the battery to "explode" after a year. Contact an authorized Apple service provider or Apple itself to see what your replacement options are.
