Q: iOS 6 iPhone 4s battery drain

Yeah, I noticed it goes back up faster to, you might be onto something with that. I guess we'll see...

I've tried pretty much everything in these and other posts - fresh install, restored from backup, disabled traffic etc. in location services, deleted facebook and twitter accounts, stopped Latitude using location services, deleted and recreated all accounts, reset all settings, hard reboot by pressing home button and power button for 10 seconds, turned off passbook and safari sync in iCloud and even turned off wifi entirely.

And still the battery is draining several percentage points every hour.

This is just unbelievable. How can Apple have put this through 4 beta versions and still made such a complete disaster of their coding? Someone needs to get fired for this; maybe then they'll pay more attention next time......

This feels like an issue that won't be explicitly addressed, but fixed in a 6.x software update. Similar to those that experienced a pop up message error when trying to sync their iphone via wifi-sync. Downside is this took about 6-8 months for Apple to sort out though and there was no mention of it in any changelogs.

Same problems with 4S. Same attempts at a fix. Took over to Apple Store yesterday.  They claimed this was the first they were hearing of it. The genius did a clean re-install of IO6 and firmware.  This wiped out all of my settings and music. Phone worked fine all afternoon with no battery issues.  Genius also confirmed that battery was healthy per their diagnostic tools.

Came home and restored my last back up.  When I woke up this morning the battery was completed drained from a 100% charge, (I usually lose 25% or so over night).  Recharged to 100% again ealier.  Now losing 1% every ten minutes while phone is ostensibly in stand by mode.

I am going to try a fresh reset and then add apps and music back on one at a time.

I'm wondering if it's the mail application.  I was having real problems getting to multiple acocunts this morning.

This is not Steve Jobs' Apple.

In an German Forum a member called Apple and they would change his IPhone 4S because its possible that iOS 6 has damaged the Processor. So if you're still in Warranty so call Apple for an Exchange.

I have a huge battery drain when I Use the tom-tom maps with my iphone4s. My phone actually gets so hot I can hardly touch it. Killing the program does not stop it from getting hot. I have to turn the phone off to get it to cool off.

Guys, my battery life sucked, so I went to settings and disconnected the integrated Facebook and Twitter settings (thinking maybe that they are constantly pinging for updates).  I still have the actual apps on my phone, but it seemed to help out a lot.  It feels like my phone's battery is almost like it was before.

I also had terrible battery life on my iPhone 4S and iPad 3. After updating to iOS 6. So I did a restore and set up both as new iPhone etc. then I restored from backup. That was 3 hours ago and the battery is still 100% I've been out on Facebook and used the phone normally....   I noticed that the phone charged very quickly so this might have something to do with it. My iPad battery is on 74% and that hasn't changed for quite a while. I'm using the iPad to surf the net and write this post. I'm going to try the maps on my phone and see what happens, I'll reply shortly.

I had the same problem and turned off 'Shared Photo Stream' recharged my battery and have been running at 100% battery life do the past 40 minutes!!

I hope it's that splenic a fix!!

Good luck 

I have used the maps on my iPhone 4S for about 15 mins a number of podcasts have automatically downloaded and the battery has drained 4% and the phone didn't get hot, compared to earlier today before I did a restore. I don't know if the restore has helped yet ill keep an eye on it and reply tomorrow. P.s the new podcast app is brilliant all my podcasts are downloaded automatically and they play in order of date, so I don't have to sit at my Mac and download and sort out my podcasts anymore.

There is no doubt that Apple has the battery problems with IOS6 on earlier/legacy iphones.  I have the iphone4S and it has the same problem after upgraded to IOS6.  There are 3 options (not fixed solutions) that you can try to do for now:

1) restore your iphone back to IOS5.1. and wait until Apple will issue with IOS6.1 when they may fix the battery issue.  In fact, this is what I will do, since I think IOS6 may even damage my Iphone4S, as the phone gets very hot and may even ruin the battery life forever.

2) I heard that if you save and then restore the iphone again with IOS6 from iTunes, it may fix the problem.  I didn't try this trick yet.

3) for the problem you described, you can actually let the phone goes down to 0%, then recharge it to 100% and let it continue charging for another hour, then maybe it will improve the battery life. 

I am now thinking, maybe I will try option 2 AND 3 first, then if it still won't improve or fix the problem, then I will try option 1.

The new 3D Maps app is really cool, but with IOS6 on iphone4S, the battery will drain down significantly 1% per minute.

does anyone actually know how to fix the problem?? we all admit there is a problem, but has anyone actually fixed it? i literally have turned off everything i can! i turned siri off, thinking that maybe i have a bad sensor like some people (not really quite sure how to figure that out). i've done the hard reset. i like most people did the update through wifi and not my computer, seeing as i really don't have a computer anymore (mine crashed). i made an appointment to go to the apple store, but doubt they'll be able to help. i was going 2-3 days wihtout having to charge my phone before the update! i was maybe draining 1% at night while sleeping. and now i drain 25%! i can't even make it 10 hours without charging my phone! to me this is proposterous. i've never had an issue with any of the updates before. then again i always did my updates on my 3gs i now have a 4s. ugh i'm so upset!!!

I as well have noticed this since the official update. I'm on Apple's developer program and curiously, did not experience this using several beta versions of ios6, only since I installed the gold master earlier this week.

I have a 4S.  For me resetting all settings and then draining to 0% (shuts off) and charging to 100% overnight fixed it.  I got about 6 hours of "usage" yesterday, including about 30 minutes of Maps (GPS).  This is with everything things than can be turned on (except Bluetooth) turned on.

The only thing I did additionally was wipe out my Reading List as I found Safari was constantly trying to download web pages that didn't exist for offline use.

I'm convinced that after every major iOS update, the phone needs to be recalibrated and does some kind of maintenance tasks in the background which causes a drain the first day or so.

Now if only Apple would fix the Springboard crashes and WiFi problems.

I have all the same problems as everyone but I have now just received a text message from my service provider telling me I am about to go over my data allowance and I will be charged extra for it. They can jog on if they think I'm paying for apples c##k ups.
