I have upgraded to iOS 5.0.1 and still have terrible battery life

iOS 5.0.1, iPhone 3GS, battery is still draining fast. Automatic timezone is trying to locate continously. Maps get location normally.

Hourly mail and calendar check is also draining battery on iOS 5.

So this 5.0.1 update is not fixing anything for 3GS user.

My iPad 2, in other hand, does not have these bugs...

you can back up your data and than setup your iphone as new and than restore data. Once you connect your iphone to itunes and backup you can restore your phone. http://support.apple.com/kb/ht1414 might help. Than restore your data back you won't loose anything.

With iPhone 4S have anyone tried turning Siri off for a night and try to see if that made any difference in stand by battery time. I know due to Siri iphone proximity sensors are always on if the screen is on. Maybe it has something to do with it in idle mode too. Just a try........

For me, I've tried turning off all location services apart from the time zone location and this purple arrow icon appears all the time even after a restart. To me this indicates that the time zone location is the main culprit. I totally regret upgrading to 5.0.1 as it was working fine for me on just version 5. I upgraded for the mere fact that it had iCloud document fixes and didn't think it would worsen my battery life.

I guess I'll just have to switch time zone location service off. Not a big deal really as how often would I need to travel around different time zones. But just annoyed for the fact that Apple didn't fix this properly and affected users who never had this issue in the first place.

I am a very light user of my iphone 4g. Single charge used to last a few days. I have noticed my battery draining particularly fast in the last two weeks. I am in the development program so have had all the ios 5 betas and none have drained my battery so I don't think it is an ios 5.0 issue. I have been using icloud generally since its release to developers but a couple of weeks ago I enabled "Documents & Data" under iCloud. Previously, I had all files stored on my devices. Is this the problem?

In the recent event paying tribute to Steve Jobs, they said that he wouldnt want them to ask themselves "what would Steve do?". In this case though, I hope thats EXACTLY what they will be asking theselves!

I encourage EVERYONE that is considering buying an iPhone to back off until this is sorted out. Maybe that will be what it will takes to get the new management team to take this seriously, for the good of Apples reputation AND its customers.

By the way i have an iPhone 4S, an iMac 27inch, a MacBook Pro and an iPad so I am NOT some random guy who just wants to attack Apple. Iam fan but so far the 4S *****. BIGTIME!

My location icon was on about 2hrs, but when i disabled wifi off, it disapeared. And turned WIFI back on, no location icon anymore... one third of battery disapeared, till midnight.

I'm with you on this one. Upgraded last night on both a 4 and 3GS. Both were at 100% when I went to bed. This morning my 3GS was at 44% and my 4 was at 55%. Looks like the 5.01 update is a complete failure. I'm rapidly losing faith in Apple. My 5.01 is a piece of crap.

The 2 settings that seem to help stopping battery drain is :

setting time zone. : off

cell network search : off

when those 2 settings are on the battery drain on a rate of 1 to 2 % each 10 minutes.

the iOS 5.0.1 doesn't help for this problem

Hi okstatefan203!

what do you mean by system restore? could you please describe it step by step?!

Thank you!

I just upgraded from a iPhone 4 to iPhone 4S (both AT&T) and after using the 4S for just one day I could tell a HUGE drop off in battery life (both had iOS 5.0.) I upgraded to iOS 5.0.1 yesteryday afternoon but it doesn't look promising. Already dropped 20% this morning with minimal usage (read 10-15 email, checked twitter and a few other apps.) I'm tempted to reactivate my old iPhone 4 until they get this ironed out... ergh.

I don't know but I don't think iPhone 4 or 3GS were affected by this update as far as battery is concerned.

i have a 3GS, same problem..**** new update, thanks apple
