Q: iPhone 4s Battery Life?

What worked for me was the iCloud restore. My guessing is that iCloud backup doesent carry over the setting that is caueing the battery drain.

1. I tried the Network settings reset which seemd to wor a little but not much

2. Backup your device to iCloud

3. Do a full DFU restore

4. Plug your device into iTunes if it isent allready and let it sync all your data

5. Get the device to run to 0% percent and shut off

6. Charge till the device is 100% with half an hour trickle charge (Where you leave the device at 100% and still chargeing) I recomend the app battery doctor for this as it will show you the time remaining and set an alarm for when its fnished if you want.

7. I also have the system location services disabled such as location based iAds and Setting Time Zone and some of the others i dident want. These would effect any device and they dont provide any purpose than giving apple statistical data.

I lost 4% battery in standy over night with all connections running, so the device was still fetching my email every hour and other services which fecth data such as Facebook so this loss in conciderible seeing as i slept for 10 hours.

And as for actual use time I have been reading emails, playing some angry birds, listening to music, just genreal use as i would before iOS 5 battery drain and i have got 8 - 9 Hours use and i have got 14% left.

Hope this helps and please report back in reply to this if it worked so others can try this fix. As i know how worried/frustrated people must be after spending alot of money on there new devices to have them not work.

Note: People on twitter with all devices from 3Gs to 4s are having the problems after upgrading to iOS 5. So its not the devices

Good luck

I wonder what the actual percentage of phones are having this issue.  I mean there are millions sold.

I may have spoken too soon--I lost another 1% in just 20 minutes and the only thing I did was power on the screen to see the battery %!

I found that the best and strongest charge happened when the percentage reaches 100%, power down and keep charging the phone for another 15-30 minutes, then power up and unplug the phone from the charger.

Wait, you are saying that I can get more then 6:45 hours of usage and 1 day and 19 hours standby?  But I already have all the settings you mentioned (Bluetooth, location, wifi) turned off--unless I am at home, then wifi comes on.  I didn't understand your suggestion, since what I was saying is that aparrently there is a "glitch" in the iOS 5 that is causing drastically battery drains.  I hope, like you and many others, this will be resolved soon.  As for my Apple diagnostic, they didn't found anything wrong, put of ordinary, with my battery.  Though, they learned that MobileMe is one of the issues...

I agree, I think the fact that some people have the probelm and some dont, its clearly and IOS 5 glitch, especially that people with IP4 and 3GS are all expereincing problems after getting IOS5..apple just needs to address with an update and stop the headache. I went to apple yesterday, they found nothing, in the end gave me a different phone and I am not sure if that really made a difference...I did all the things people are talking about..i cant believe how many times I restored my phone...and how many settings I played with...nothing makes a huge difference...so its either SIRI, IOS5 or apple just plain didnt get the battery size right this time...the weeks to come will tell I guess...Ill keep draining and charging my phonee..but I'm done trying to restore the phone and toggle all these settings...i can turn wifi, bluetooth, and push stuff around and location stuff...as a new user to iphone, i was hoping I would get away from all the phone manipulation that Android required and which was also the reason I came to apple...but maybe i'm not so lucky..

Apple gave me another iP4S today and we'll see how it goes. I can't connect to the iOS5 argument as my iPad has the same configuration and my iP4 has only minor differences and they have not been losing power like my first iP4S.

Do you think apple would have that many phones with bad batteries?

In my opinion this is not the fault of the battery, only iOS or any component inside. Try turning on airplane mode and then use the phone (though hard to use without internet then), then the battery goes down very slowly.

Has there been any kind of  response from Apple yet about this ?

Sorry my post wasn't clear enough. When you perform a clean restore and set up your iPhone as a new phone. The phone with it's default settings shouldn't be using much power at all. Especially if WiFi, Bluetooth and location services are turned off. If you go through all of the settings and turn everything off (Siri, Facetime, iMessage, Ping, Notifications), apart from mobile data this will essentially make your iPhone into a telephone. If it uses more than 1% of battery in under lets say 90 minutes in this state, I think that there is a problem with your SIM. In this state I burnt through 22% in 6.5 hours with the SIM straight out of my IPhone 4 that I bought last year. Which is rediculous. I swapped it out for my girlfriends brand new SIM that came with her iPhone 4s and left it overnight and it was using 1% every 2 hours. Big difference!

Nope, nothing from Apple yet. Are we surprised?

They either know exactly what the problem is and are preparing a update, which is in testing right now. Or they are unsure what the problem is and are data crunching like crazy.

Either way I wouldn't fancy their jobs right now.

Hey bwulfe,

I'm in the exact same boat as you. San Antonio, 64GB 4S, ran the beta on both a 3GS and 4 and witnessed the same battery life dips and peaks through the various betas. Currently have identical symptoms as you (on the 4S).

I picked mine up on Sunday from the La Cantera store. If this is some sort of batch issue, we may both be affected due to proximity. Hit me up (iMessage) and we can sync notes.

or they dont think there is a problem at all and will do nothing..its like they really did anything when antennagate happened..they gave people free bumpers..not sure that was really a solution...everyone remembers the late steve jobs said, phones lose reception..its no big deal..

Problem is no one really knows how widespread this problem is.
