IOS 4.3.3 battery life has been significantly reduced

This is getting annoying!

After various resets, restores, battery run-downs and otherfiddling my iPhone4 was behaving very well for ages with about 30%-40% drain during the day in normal use even with 3G, WiFi, push email all on. Last night I downloaded a few app updates, played a game or two and went to bed leaving about 70% battery only to find it completely flat this morning. As no settings had changed I can only assume that it was a runaway app or something in the sync process that caused it.

If it is runaway apps causing the probs then the OS should really monitor and terminate long-running high-cpu apps.

Sigh.

hi everybody...i've read all 10 pages...well

i have the same problem after 4.3.3 installed and tried to find a way, putting off

localization, push, wifi, bt...boring having an half-phone and no solution again

then searching on the web i 've read that many people found this solution great:

just turn off the applestore account on your iphone

and turn on all you need ...

after 5 hours ALL TURNED ON

only -2%

just remember that after a syncro with itunes

you will have to torn off again applestore account on the iphone

please try this way and let me know if it works for you too

I have the iPhone 4 and had no problem with the battery life until I uploaded the 4.3.3. operating system. Once I did that my battery wouldn't last more than 4 hours, even without any use. I tried all of the suggestions above but didn't have any success until I turned off Push. Now what I have to do to get email is open the email application and have it retrieve new emails as it is opened. I no longer get notified of emails but my battery is working as it did previously. I have now had the phone unplugged and in use for the past 16 hours and still have 39% battery life left. The final solution is obviously a software fix but for now, my battery is not draining improperly.

I'm at this point completely unsure what the issue is ... I've read and tried everything in this entire thread. Not sure what to believe as it seems different fixes seem to solve different peoples problems.

At the moment, I'm @ 68% battery left with 2 hours, 23 minutes of usage and 13 hours, 3 minutes of standby .... This I can deal with. BUT .....

I have PUSH turned off, Calendar turned off (which is killing me with 12+ meetings a day), Location services turned off (which *****), brightness @ 50% , and so on ...

So the way I see it, I have to turn off some of the features I NEED , to maintain the phone long enough to make it usable for a day .... This I did NOT do with my BB .... I had everything turned on and went days without issue.

Software Issue? YES .... but when will this be fixed ? Has Apple even publicly acknowledged this yet? I dont believe so which is hard to believe quite honestly .... STEP UP and fix things Apple.

I'm on the verge of buying a Playbook and a new BB ..... at least I will be able to use everything as advertised, and not drop dead in 4-5 hours.

Maybe I should have only considered an iPhone as a fancy iPod , with a phone feature in case of emergencies ? seems to me that for any type of business use ... this thing is FAR below standards.

I turned off the apps store account. that solved the problem.

I would like to try that, but how do you turn off the apps store account. I've looked in settings and there does not seem to be anything that says app store account that I can turn on or off.

How is this done?

TIA,

Ken

63% battery ....

2 Hours 49 Minutes usage

16 hours 11 Minutes standby

No BB , but seems ok at the moment with all my cool iPhone features turned off 🙂 I'll be back in a bit after I check my email on my computer since my wicked cool "iPhone" can not handle telling me I have new email (PUSH) ... without a car battery attached 😟

Most fancy, flashy "brick" phone I have owned since the 80's 🙂

go to Settings > Store > Click on the ID > Sign Out

after one day of regular use

full recharged by night now i'm still at 100%

i 've read 3 mail , posted on facebook and a call

so put off the appstore account on your iphone !

Hi,

Understand you signed out from your AppStore acct...

But, is your Push being switched OFF too ?

wich push do you mean ?

all it's turned on, mail, notification, localization....

Settings > Mails, Contacts, Calendars > Fetch New Data > Push ---> ON or OFF ?

When I set it to ON, it drained my battery within one night on stand-by mode, with my Exchange Email activated.

push switched on , download setted on manually
