IOS 4.3.3 battery life has been significantly reduced

Updating to 4.3.4 will help.

The solution is 4.3.x. I have no battery problem with any of the 4.3 versions.

Regarding 4.2.1:

IOS 4.2.1 battery drain

Iphone 3GS 4.2.1 problem-battery

Update 4.2.1 has shortern my btter life.

3G running 4.2.1 Battery Drain FAST!!!

after update to IOS4.2.1 my 3Gs battery % keep dropping

battery drains fast with 4.2.1

Battery drain has nothing to do with any specific version. It can happen with any version, or even between versions. And there is no version that will fix it. I could have linked just as many threads for any version that has ever come out.

Having a similar problem, got my iPhone in December 2010:

Back in March 2011, my battery would drain 7-8% overnight suddenly, whereas before it would drain maybe 1-2% overnight. All apps closed, no 3G, Location device off, Bluetooth off etc, no Email Exchange accounts set up. I restored the phone as new and used a backup from iTunes, things returned to normal.

Now 4 months later, the same problem occurs, I'm not sure if this happened last time as well, but my Usage hours would increase by the same amount as my Standby hours. So I restored my phone again last Friday, thinking it will fix the problem, and it did, for about two days, before the problem returned.

When I updated iTunes to prepare for my restoration of iPhone - it did pop up with something saying update wasn't able to complete, but when I checked iTunes version, it is the most up to date version. My iPhone now has the most up to date version of iOS (4.3.4 8K), whereas before I was running iOS 4.2.1.

Things I have tried:

• Restoring and updating iPhone <--may try again, this time just restore as iTunes wouldn't let me just restore to 4.2.1, but forces update & restore to 4.3.4 (8K)
• All battery draining culprits are off - Ping, Bluetooth, 3G, location etc.
• I deleted my gmail account, installed it again - letting it load, then deleting it again
• Hard reset
• Log out of Apple Store

Yet to try:

Running battery to the ground, and then do a full charge - doing that tonight

My phone was fine for two days after I restored/updated it - then maybe it's the adding of Gmail and deleting the account <--perhaps something is in the loop. But I did re-add Gmail, and deleting it after I let everything load.

Any other ideas?

I found a very crude and permanent fix. If you badly need your battery power or expecting an important call and you need the juice, using sbsettings, reboot in safe mode. That should keep you alive more than a day.

Problem Identified & Solved !

*****************************

I recently bought a new iPhone 4, upgraded it to iOS 4.3.3. Power usage was excellent (very low) for many days until one day it suddenly started to drop a lot and at a fast rate. Upon thorough investigation I narrowed it down to one particular app which runs real time TV news and was recently installed by me.

It seems that if you run any real-time app (like real-time TV) and if you quit while that app is running (i.e. you press the home button) then that app continues to download/run in the back ground even if you think it has been closed. This causes the power drain. This also explained the sudden surge in unexpected data download observed on my usage page.

I fixed this by re-starting that defaulting app and switching to any "non-downloading" page (for example the main options menu) and then I pressed the home button. Every thing went back to normal (good battery savings !)

In case you do not run any real-time TV --- check for simillar apps like live radio or live music or any live streaming which you may have quit in the middle by pressing the home button. it will be running in the back ground causing all the power drain and unwarrented data bandwidth usage.

iOS Fix : Irrespective of this being an app bug - I think iOS should take care of this. In my case when I shut the real time TV app (by pressing home) iOS should terminate completely that process (and any child processes). How ever there may be cases where you would want iOS to NOT terminate the process (like valid file downloading or real-time AGPS tracking or reading a book etc.) ---------- so I guess iOS should make this user configurable. An extra switch which allows/disallows background execution will solve this problem. Additionally, apps upon start up may be allowed to default to either background executable or not (it should save a current context and terminate/stop itself).

The FIX recommeded in this discussion - to do an iPhone power reset - would have terminated the defaulting app and fixed the problem. How ever and obviously this is NOT THE WAY TO FIX this problem i.e. resetting the iPhone all the time !!!

Adding further to my above post --- I came upon a reply in another battery related discussion which describes how to switch off back ground running tasks in iOS. It is a must read !

I do believe most of us that still have the issue are aware of background tasks running and do end those tasks daily, but I am happy this resolved your issue.

Hello Joe,

I have my iphone since two weeks, I had a very good quality in battery life (acctually I was suprpised about it), Since yesterday I did upgrade my operative system to version 4.3.3, and now I have a very poor quality in battery life (same problem that you had)... I tryed all tips fromhttp://www.apple.com/batteries/iphone.html but useless so far, in addition to this I found that even when I`m charging the iPhone it takes less time to charge than before... I`m really disapointed I liked so much iPhone 4 but this thing makes me feel really bad about it.

please help me out with this issue... this this battery life iPhome is just another phone in the market.

Hi All,

since i made a update to IOS 4.3.3 on my Iphone 3Gs i got the same problems with the battery drain. My iphone lost battery capacity around 20 % a night.

Now i analysed this phenoemen and found the following: Only Ios 4.3.3 (without any Apps) is installed on my iphone and a process runs in a loop and use the battery and usage time (more than 2 hours a day). And too, makes a connection to the internet and get more than 10 MB a day.

My Solution: You have to log off from the App Store on the Iphone

After this the battery drain and the usage time on the iphone is back to a normal level. And too the usage of the internet connection is 0 Byte all the day.

Try my tip and let me know if this work on your Iphone too.

Worked for me!

Hi all

Just been through this - battery draining almost faster than it recharges for two weeks (now on iOS 4.3.5).

I tried all the suggestions i could find here and on several other threads including: Quitting all apps, disabling backgrounding apps, installing things to "clean" the memory, logging out of iTunes and App Store, restricting most apps including Ping, switching off cellular data, deleting mobile.me and all email accounts, resetting network settings, etc etc.

What fixed it for me (so far) in the end was: Settings -> General -> Reset -> Reset All Settings

Hope that helps someone,
