Q: iOS 6 iPhone 4s battery drain

Mine has crashed and restarted out of the blue too. Not my iPad that I have observed anyways. I am also seeing crashing with my iPhone...Safari, Mail and especially Settings. I feel like we are a team of Sherlock Holmes's stuck in an endless loop on these forums!

I got 7.5 hours today, with little use, which is much better than yesterday. Even though rural yesterday, I had it in Airplane mode for half theday. Oh, just recalled. I shut it off with the Power Down slider and put it away. When I checked it a little later, it was on again. Maybe we need an exorcism.

Full overnight charge coming again. Now dead, so will recharge beyond fully and see what happens. It has died so many times before that I don't think the full discharge is the answer for me.

And while it heated up yesterday at the rural golf course, it didn't today at the office and after a full night's charge. More clues.

My iPhone 4S is also having major battery drain issues that only just started with an OTA update to iOS6.  It was at 100% charge this morning at 9:30 a.m., and by 2 p.m. (without any use), it had completely depleated the battery and shut itself down. 

One thing I have noticed is that iCloud bookmark sync is having problems on the iPhone.  If I turn off the syncing for Safari on the iPhone and tell it to delete my data on the phone, it doesn't remove the bookmarks.  If I try to remove the bookmarks manually, I get an error that says I cannot delete bookmarks while they are syncing.  Well, I had turned syncing off already and asked it to delete the data! 

The upgrade process on my iPad 2 to iOS6 went smoothly and I am not having any of these issues there.

Basically, at this point my phone is almost useless to me, so if an Apple employee see's this message and you want me to install any kind of monitoring software to help troubleshoot this issue, please contact me.  I do a little coding for my work, and realize that it's literally impossible to release software that is completely bug free, so if I can assist in the troubleshooting process in any way, someone get ahold of me.

OK,

I'm happy to report that after setting both iPhone and iPad up as 'NEW DEVICES' both are performing normally again.

I've been surfing the net with Safari, checking male, listening to music and battery usage seems to be normal again.

I know it's a hassle, but it seems to have worked for me.

Hope this helps others.

I did OTA, but have noticed iCloud syncing problems too. Another clue! My iPad seems Ok.

The amounts of clues in this forum is amazing.

BTW, I had to reset to new back at the release of IOS 4, and it worked much better. I upgraded on day 1 and got the "Well, what do you expect? Their servers are going crazy." I forgot about that this time. The upgrade went smooth, but I wonder if something could happen with so much server activity at their end. That's beyond me.

Whoever said Apple was slow to come out with an update fix was right for those issues back then and with IOS 5. Probably can't blame them. It must be an awesome process over there right now, trying to get this thing right and not make any mistakes with the update. I bet they are happy not to have Steve looking over their shoulders. But, I would be in favor!

I have none of the problems you mentionned.

Yeah when it happened I was connected to my WiFi, but it never happened at school and there im also connected to the wifi.

Same problem.  Did a reset, let battery run all the way down and fully charged.  Still cant get more than 1/2 day without the battery dropping below 30%.  OK, Apple...where's the fix?

Same problem!! I am need to recharge it almost 5 times each day, Help!!!

Hey Khoolman,

Thanks for sharing. I did the restored factory setting and set up on my iphone 4s to new iphone and sync my backup from Itunes like what you mentioned, and It WORKS. Now my 4s is bahaving like what it used to.

In addition, I'm still on the battery life saving tip from (iOS5.1)

My current setup for iOS 6.0

- Restored Factory Setting (with Itunes)

- Set up Iphone 4s to New Iphone (on the Iphone)

- Restored Backup from Itunes

- Drain the phone to 0% that the phone shut off by itself. Full charge it continuesly from at night untill the next morning.

Settings on Iphone 4s

1. Notification - only switch ON the nessesary apps

2. Auto-Brightness -OFF. I switched off because, in AUTO the brightness went to maximum bright accasionally

3. Mail Setting - Turn Shared Calender Alerts OFF

4. Itunes & App Stores - Turn everything OFF

5. ICloud Setting - Turn everything OFF. I back up in Itunes will do.

6. Facebook & Twitter - Disable Facebook integration

7. Facebook & Twitter - Disable Facebook Contact integration

8. Facebook & Twitter - Disable Facebook Calender integration

GENERAL

9. Diagnostic & Usage - Don't Send

10. Cellular Setting - Turn OFF Itunes, Passbook Updates, Reading List even Facetime. I don't use Facetime often. I leave Facetime operating with Wifi only.

11. Advertising Limit Ad tracking -ON

PRIVACY

12. Location Service -  only switch ON the nessesary apps

13. System Service - Switch OFF Genius for Apps, Location-Based IAds, Setting Time Zone

14. Facebook - Switch OFF. (Your facebook is still working, just that you log in with your email in facebook app rather then logging in with IOS).

There. These are the settings that suits my needs.

Hope this help.

The only thing to disable is icloud.. If you disable everything else, you may as well get a droid phone or something

Anyhow, my iphone 4 with ios6 now can last about 8 hours instead of 16 hours a day!

With that icloud sync enabled, probably in 4 hours, my iphone will be dead.

Guys, i did some investigation on my current settings. I upgraded to the iPhone 5 from an iPhone 4. I did not set it up as a new device, I used my backed up 4's data and restored from iCloud.

After doing a lot of research and investigation and talking to Apple too i am a 100% sure that its a bug in the restore process. After restoring to iPhone 5 for some reason the apps + system process think that its an iPhone 4 with a single core A4 processor and et all. Whereas its an iPhone 5 with A6 processor et. al. The software and the OS aren't using the hardware as it is meant to be used due to the conflicts brought along with the restore thereby impacting the battery life.

We got 2 options:

1. Erase all contents and data then Restore your phone as a new iPhone and manually download apps

2. Wait for apple to release a fix.

P.S. definitely let your battery drain out fully once and give it a full charge after that (did work for me a little before i found the actual bug)

I do not think this has anything to do with "Restore"

Many people just upgrade the IOS 6 from IOS 5 without restore, iphone 3gs, ipad, iphone 4 also got affected into this.  I had Iphone 4, and after upgraded, it drained so crazily, but it is better right after I turned off the icloud sync, still it is not as good as before.  One full charge may hold up to 7 to 8 hours - on and off use.

One of the new IOS 6 features is called "battery drain"...

Bug?  Now I know why the Apple logo has a bite out...  Probably there is a "bug" inside the Apple already!!  

I have de same problem.

And an i message problem too. my messages from the i phone appear only on my i pad ( the answers)!!!

Good thing!

Well my iphone battery just started dying super fast today out of nowhere.  After looking online and trying different things with no help I read an article about how they think its a bug with location services / setting time zone.  I turned this off and I have not dropped 1% of battery for the past 30 mins.  I did not reset my phone or any of that.  I rather not do that if at all possible.

Settings - Privacy - Location Services - System Services (very bottom) - Setting Time Zone.  Turn that off.

Good luck

I try this now. lets see.

But the problem with my imessage... continues
