Battery Problem Fixed On iPhone 4S

Works for me! thanks op!

I combined what the OP said and what CNET said:

Head over to Settings, then Location Services, and finally System Services. Right at the bottom you’ll find a toggle switch for “Status Bar Icon.” Switch that on, and watch to see if your location icon pops up in the status bar. If it does, we might be on to something. If not, well, follow the rest of the guide just in case.

The second part of the test requires you to now switch off ”Setting Time Zone.” Did the icon disappear? I’m betting it did, and if that’s the case, you’re in luck.
See, it appears that iOS 5′s GM release introduced a bug that causes the Setting Time Zone function to keep the location tracking circuitry running constantly, draining battery power considerably. Switching it off may mean that your iPhone will no longer set its own time zone when you travel, but that’s a small price to pay for having your iPhone last more than 12 hours on a full charge.
Leave the rest of the location settings on. There’s no need to cripple such essential functionality, and it appears that the Setting Time Zone option is the one that causes the hit on battery life.

And holy crapola, i will post screens of the before and after after I run my battery down. But that might take an entire day or two now! :)

THANKS!!!
 
I restored as a new phone, and then restored from the backup I had taken earlier. It seems to have reduced the battery drain considerably. On standby, the battery is now draining at the rate of 1-2% per hour.
 
This seems to have worked for me. Wasnt impresses first time with the 4s and I literally watched my battery deplete...
Got slightly better after a full cycle but still not that mpressed.
Tried the setting changes, and removed my exchange account and icloud but still bad;

Last night restored as per the OPs instructions but didn't restore my backup as there wasn't much on there.

Still did turn off cell search and time zone in location, but unplugged at 1am last night and 6 hours later (Clocks went back so it IS 6 hours lol) I still have 99% battery whereas before I'd be easily on 90% or less.

We'll see what a days usage brings. Quite funny if it is just a batch taht either had a corrupted build or a fix has been issued on the quiet!
 
trying it out right now and will post back. I was not aware there was a battery issue and really had no iPhone to compare it with but I do notice the crappy battery life. I was already at 50% off and I barely used the phone for 1 whole day.
 
Do anyone know if the backup contains the settings for my work e-mail, so i dont have to get help from the IT department again? :)
 
I did this yesterday morning at 8am, my 4s had 26% battery left at 1am when I went to bed, used it quite abit all day so not overly fussed, but how does this compare to what others are getting?

Dunno if this is about right either, seamy better but now in use am watching it deplete!

Currently on 9.5 hours standby, 38min usage (Facebook, twitter and light browsing) and am on 88% left... However that's dropped from 91% in last few minutes (also listening to music on train to work right now)
 
...or just Reset All Settings for a similar effect. Also restore as new won't work for everyone.
 
Not fixing the problem for me, though I appreciate the tip. Along with this, I've done other things suggested, i.e. turning off time zone sync, iCal notifications, and Siri raise to speak.

Nothing works for me :(:(:(:(
 
Well worked for me - and the results are pretty dramatic - 94% after 4 hours 11 mins on standby with 24 mins of usage. Previously it would have been in the low 80's in terms of percentage. And I've been in the car, travelled 40 miles along a motorway with the bluetooth and wifi on - and bluetooth connected to my car.

Thanks for the tip!
 
I'm unable to locate my backup file. I can see that it did one under Devices in iTunes Preferences. But I've searched and can't find the file. Is it because I've chosen to back-up to iCloud? Is it not storing a copy locally anymore?

Ok now at 15hr41 standby 2.5hrs usage (browsing, SMS, couple of quick calls) and still got 63% left I'm gonna say that for me this worked for whatever reason - and I did already try a "reset all settings" with no effect.

Seems very strange but please this now works and I can enjoy the phone away from a power supply

I'd say that turning off the percentage indicator and not obsessing over is a great tip here
 
I've noticed that after using the facebook app, if I go back to the homescreen (app is still running) that my battery decreases much faster (relatively).

Everytime I have manually closed the facebook app, my battery seemed to remain still on standby for a lot longer, than if app hadn't manually been closed. Just a thought.

Question about iCloud Backup/restore

I'm unsure about iCloud backup/restore.

When I got my phone I set up iCloud backup. Now if I restore my phone it'll ask if I want to restore from iCloud backup when I sign in to iCloud. If I say no will it delete the current backup or will it leave it until I turn iCloud backup on and make me choose at that point?
