Q: IOS-5 battery power drain issue

The problem I am having is the battery life.  I updated to iOS 5 and started having problems with the battery draining very quickly even without a lot of use and quiting all my running apps.  Then when iOS 5.0.1 came out and said that the battery problem was supposed to be fixed, I updated to that and the problem became worse.  I restored factory settings and I am still having the same problems.  If anyone has any suggestions, please reply. Thank you.

ok ive tryed like everthing on here and nothing has helped that i can tell but to the people that say to turn everthing off, whats the point in having the phone then?

I agree with you. You should not have to turn everything off, or even a few things off. But please list what you have tried. One person's "everything" is not the same as another's.

Se my post in another thread about what I consider "everything". https://discussions.apple.com/message/16719991#16719991

I don't know if this has been covered elsewhere. In case it hasn't, I've seen this battery issue on two phones with iOS5. One was a 4s the other a 3GS.

In both cases, the issue was fixed without really turning anything off. The only setting that needed to be changed was to set the carrier setting from automatic, to manually selecting your carrier. I think for the majority of people this setting wouldn't change anyway.

I don't know if it will work for others, just thought I'd share my experience. It seems like the battery is drained by constantly searching for other networks or soemthing. Anyway, worked for me on two phones.

Settings > Carrier > Automatic = Off.

I don't see "settings>carrier>automatic=off"

Well, unless it's only available on unlocked models? Here are the screenshots from my 3GS. Just tap, where it says on and it'll switch to off and you can set your carrier manually.

I am having the same problem and have tried everything including buying battery apps. Phone was fully charged and with 1hour and 54 minutes of usage its at 50%. Oh and I have everything turned off as well, good 3G and great wifi.

I hope someone at Apple is reading this stuff.

Maybe someone can help me with this. I have a 4s and in trying to listen dotcom78 I noticed that personal hotspot was constantly searching. I shut it down and found some uknow password in there.  Could this have been draining batter? 

I never set that up so how would a password be selected already?

The password is set randomly and automatically by default.

Update your devices to 5.0.1. This fixed the battery drain issue.

...then we can finally close this thread,

I'd definitely turn personal hotspot off if you're not using it.

I was referring to disabling automatically searching for a carrier. Availlable Carriers (your phone company) will vary from country to country.

Again, the setting may be unavailable on your iPhone due to some carrier restriction or something. Your phone may need to be unlocked or something depending on where you are in the world.

@beejster From what I understand, iOS 5.0.1 has not resolved the battery issues for everyone.

@dotcom78 have you tried?

Battery on ipad2 still depleting rapidly.  Patch did nothing. I have tried everything.  Come on Apple.  Do more. Do better. Do it faster.

@beejster I've never had a problem myself. I know of two other people, one with a 3GS and one with a 4S that were having the issue and the carrier setting fixed it for them.

I'm not saying it's a sure fire fix for everyone, or that 5.0.1 wouldn't fix it. Just figured I'd share my experience in case it was useful as there are still a lot of reports around that people are still having battery issues even after installing 5.0.1.

If 5.0.1 fixes it for people, great. If not, it's just something else to try.

After my husband urged me to move to iOS 5, I  upgraded my 4G iPhone to iOS 5.0.1 on Friday. Since then, my formerly great battery depletes in about 10-12 hours with fairly minimal usage. I turned off most apps that I normally run, including turning off WIFI when I'm out of the house and 3G when I'm in the house. 

Also, the finger touch is way less sensitive in many apps than it used to be.

This is very frustrating for me - a fix that was supposed to fix some people's battery issues causes battery problems that were not there before.

I don't know what to do. I do not have Carrier option in settings, FWIW.
