Q: Battery life/iOS 5.0.1

Fix that worked for us...We had several phones that experienced rapid drain following update... and the solution was to DELETE the mail profile and rebuild it.  We had this exact same issue occur with a release of IOS4 and Iphone4s last year.... which is what lead us to try the fix again.  It may not be the magic bullet for everyone but we are batting 1000 here.

5.0.1 is  broken.

5.0.1 is worser than 5.0.

Updated my iPhone 4 from iOS 5 to 5.0.1 and this was a big mistake.

Pandora and iHeartRadio just drains the battery (almost 10% and hour).

Come on Apple. Either fix 5.0.1 asap or give us a way to go back to 5.0.

I'm seeing the same thing on my iPhone 4.  It's tough to say whether 5.0.1 made my battery life worse, but it certainly didn't make it any better.  I'd be interested in knowing which battery-related issues were in fact fixed in 5.0.1, as noted in the Apple change log.  Currently I'm having to charge my iPhone at work during the day so it makes it through a full day - never had to do this with iOS 4.x on the same hardware.  Intraday recharging isn't horribly inconvenient when I'm at work or at home, but it's bad when traveling.

Fix this soon.  I had no problems with battery life until 5.0.1.  Now it looks as if I will not make it through the day on one charge. 

Same problem here. Update my 4 to 5.0.1 and it is draining my battery as ****.

I didn't had any battery issue with IOs 5 (max 15% a DAY !!!) and now 20% in 4 hours.

I've tried everything, location is off, reporting is off, time auto adjustment is off, re-installed my mail, reset the network settings....

I hope we have a fix really soon :-/

Battery life was never great in 4.3, but at least I could make it through the day. 5.0 dropped the life to about 12-14 hours. When 5.01 came out i said YEAH! I up'ed to 5.01 last night and connrcted it to charge over night. unplugged this morning at about 8:30 AM and the phone shut down about 5 PM. Only 2 calls total phone time about 15 minutes.

I hope they fix this quick!!

It looks like the problems from iOS 5.0 have spread to the iPhone4. half my battery life gone overnight and no WiFi. These problems were not evident in 5.0. No other changes made apart from the "upgrade" to 5.0.1 over the air yesterday.

Battery draining in my iPAD 2 wifi only version is high. The drain is so fast after iOS 5.0.1 update ..After continious browse for 31 minutes the batter percentage droped to 6 points. Apple team come on provide the solution

apple what are you doin your goin downhill fix this battery issue..with this new update it has gotten significantly worse do something about it how can i brag to ppl on how great it is when it only lasts 5 hrs..i dont understand how a big company as yourself claim to make the bests products and this iphone was well overdue doesnt even work properly DO SOMETHING im losing intrest in apple

Battery life was great on my Ipad 2 until 5.0 which made it worse and 5.01 had made it even worse.

I didn't have a battery problem.  After 5.0.1 my battery lasts even longer.  Phone now goes over night with no charger and still says 100% in the morning.  Have you guys looked at your iCloud settings, WiFi, and Bluetooth.  Your phone could be syncing with the cloud.  I turned everything on the cloud off except find my iphone.  I would rather just sync using usb.  It is faster and I only need it once every week or so.

IOS 5.0.1 is definitely Downgrade and not at all Upgrade!!!

I want my battery life longer but not shorter.  Apple:  FIX IT NOW!!!!!

There is another wide-spread problem (at least in the Czech Republic) with 5.0.1: the iPhone 4S becomes unusable after the update if you use T-Mobile. "Unknown SIM" problems occurs several times an hour, or you have "full signal" but not reachable, you have to try 5-10 times to make a call, which means the iPhone is a priceless brick and there is nothing what you can do about it.

Why should anyone have to turn off services that are part of a piece of kit just to try and fix a bug.

Apple should research better than to send out a bug ridden operating system.Itis highly unprofessional and unacceptable and each and very person showing a genuine problem should be able to go into an apple shop and replace thier phone

My iPhone 4S's battery was behaving reasonably well until I upgraded to iOS 5.0.1. There is noticeable battery drain. According to my calculations the standby drop has increased by 3.7 time. I am going to recalibrate it by draining the whole battery and recharging to full.

Disappointing.
