Q: iOS 6 iPhone 4s battery drain

Con la actualizacion a IOS 6 desde mi iphone 4 noto varios problemas que espero que se arreglen con otra actualizacion:

1º-Menor duracion de bateria.

2º-Entro en cualquier app (incluida la store) y me devuelve al inicio.

3º-Problemas con la app mapas.

ETC.

I was having terrible battery drain.   It was draining at close to 20% per hour without any use and much faster if I were actually using the phone.   I tried everything listed on here.   I turned off Safari, I did a hard reboot, all of the Location services were turned off, Bluetooth was off.   Nothing worked.   The last thing that I tried was to erase all of the Safari website data (Settings -> Safari -> Advanced -> Website Data -> Remove All Website Data).   After that, I did a hard reboot.   So far it appears to have stopped the battery drain.   As I mentioned, for the last week, I've been losing my charge at absurd rates.   So far today, I'm at 80% - 5 hours after a full charge with moderate use.   I'm not sure why this worked and whether it will be a permanent fix, but so far so good. 

tried to restore and reinstall from back up in itunes.  Told me it was corrupt and so am starting as a new phone.  Not happy about having to start from scratch here.  Hopefully this will solve some of the isues.

I too had this problem after doing an OTA install of IOS6 on my iPhone 4S. I would lose lose 1 percent every few minutes even while the phone was in standby. When actually using the phone it would drop a few percent every minute or less. I was able to mitigate the first symptom by disabling the iCloud synch, which was nice, however the drain during usage was not affected.

I have seen several restore related posts, most stating to restore to factory settings and set the device up as a new phone. Rather than go to that extreme I decided to try the safer path first.

1. I connected my phone to iTunes, went through each tab (Apps, Photos, etc.), ensured that I had everything checked which I wanted to protect, and then initiated a backup.
2. Once the backup was completed I went back to the "Summary" tab and selected the "Restore" option, which then pulled the full IOS6 install down and was applied to the phone during the factory reset process.
3. Once the restore was completed I was asked to set up the phone as a New Phone or restore from backup. I picked the latter option.
4. The backup was then applied to my newly installed OS on the phone, and I ejected the phone upon completion.

The above is not meant to be pedantic, but I figured I would outline the steps I went through for those who are not familiar with the restore process.

The end result: My phone is now on IOS6, I have iCloud synch turned back on (as well as everything else), I do not have to re-configure my device or apps, and my battery life is now actually BETTER than when I had IOS 5.1.1 on it.

I am wondering how much of this problem is really attributed to faulty OTA OS patching. Irrespective of that, I now have my phone back, and my battery life back (improved even)!

I hope that someone finds this post helpful and also can have their phone returned to them the way it was meant to be.

I am in the process of doing this very same thing.  If it works on my phone too, I'll post the results as well.

Okay, so Ive finally had enough and went to the apple store, where they performed a diagnostic, I told the guy everything that was happening which was massive battery drainage including while on stand by. He claimed to not have had any reports of the ios 6 having bugs, he had the nerve to say these things could all be in my and everyone elses imaginations or it could be the phone just needs to get used to it. To make a long story short apple clearly isn't going to say their software has bugs and who knows when we'll see a fix, in the mean time we have to accept our devices current state and performance. I have tried absolutly every single possible solution with little to no change.

Hi John - I received a call from an Apple technician because of my three posts to this discussion. They are working hard on this but he had no answers yet.

As for me, I thought I had my phone behaving much better after a restore, but alas after trying many things my phone battery is draining much too quickly. There is a problem or several problems, my guess is aside from turning off most features this will only be solved by an update. On the upside the restore has cleaned up a number of issues I was having since I started using iTunes Match.

Hi, I have the same problem that everyone else is having also. I have done the restore while connected to PC and let the battery drain fully and then did a full charge for 8 full hours. I dont see any improvement yet.

Apple are working on it !

I bought my iPhone 4S at March. First I had some battery drain problems with ios 5, that where solved with a hard reset. I had the "speak to raise" problem, the IR sensor was always ON and I could solve it with a hard reset with DFU mode.

Now I have installed ios 6 and I'm having the same problem that I got with ios 5. Battery drain unacceptable and again the same problem with the IR Sensor.

I have done 4 Hard resets, 2 normal hard resets and 2 DFU hard resets cia itunes, and it has not changed. The IR sensor is still ON when the screen is ON, even with "raise to speak" off.

What can I do to switch off the IR sensor=??  (( I have tried all the fixes that I have read on this pages ))

PLEASE HEEELP!!

Following up my earlier post after setting up as new iPhone and not restoring I used my phone for email and exchange and a little web surfing.  The phone is actually getting respectable battery life although at an unrealistic cost (my data is not restored)  .  For what it is worth the proof is clear that a 'clean' build works

respectably.

In no way am I saying that people should do this to make their phone work - apple has to fix or they will have no end of calls.  I also know many with the same iPhone who do not have any problem - not sure why the inconsistancy. 

Apple scheduled to call me back at 7PM tonight - but they were off by 4 time zones and called while i was at work.

IOS 6 battery drain issue on iphone 4s

My battery is draining like anything from the day i got ios6 on my 4s. Already did reset but nothing happened. even swtiched of most of locations services and everything i could but nothing.

only hope of itunes restore and then see.

apple please fix this n release patch.

I just bought iphone 4s on eBay and update it on iOS 6. Now, i've got only 3 minutes per percent while browsing Safari with 3g. So i've turn on Airplane mode on and start a timer app. 2 percents for 11 minutes just timer app and screen on. Could somebody tell me is that weird or not? Thanks!

I'm experiencing the same issue. my battery goes to 50% after 3 hrs++. I don't have this issue in IOS5. My phone can stand almost 1 day before i need to charge. I seldom use my phone.

I have gone through all the tips here and shut down anything that could drain the battery. Most of these things I had turned off in iOS5 already, iOS 6 turned some back on and more..

I have done the reboots, no apps running and my battery goes down to 65% in 4 hours with no usage. Just sitting in my pocket. I have an iPhone 4S that was in perfect working order with OK battery drain before the update to iOS6.

Apple - please come with a patch? How hard is it to spot these problems before rolling out an update...
