iOS 6 battery issues?
- Thread starter The-Pro

- Sort by reaction score
I've noticed some some slight battery issues on my iPhone 4. I've lost anywhere between 10-15% more of using it the same amount.
I really don't know what is wrong with my iphone 4s
During weekdays my battery seems to drain a lot faster compared to weekend.
Here is today. I basically can't get through the day without my car charger. I have no idea what the problem is. Maybe the school network or sth?
Btw, this usage is just %90 whatsapp and 10% checking traffic to estimate when to leave. This is a huge problem.
But on the weekends i get about a day with 3-4 hours of usage. What's wrong?

I fixed my issue with the rapid battery drain. Looks like the phone kept trying to sync with ICloud. None of the resets fixed my issue. Reloaded the OS had it sync with ICloud again I saw the process was sticking on picture sync did another reboot the count on my pictures dropped from 500 to 481. the Sync completed and battery life is back to what it was.
**UPDATE**
This only slowed my issue down it did not fix the problem as a whole.

Interesting...but i didn't get it well..what i'm supposed to do? Turn off iCloud? ALL the iCloud services?
No, you shouldn't have to turn ICloud off. I did that after the restore to force data to correctly sync. Also this may not be the silver bullet to fix the issue just something that I ran across.
I think I fixed my battery issues. I discovered that the Cell Network Search system service was using my location every few minutes. I turned that off under Location Services and my battery life is much better now. Don't know why it was doing that, since I never had that problem in iOS 5.
Cell Network Search Draining Battery?
I too turned off cell network search (thanks for the tip!) after turning off auto brightness and setting the brightness manually. Auto brightness in IOS6 seems to get very over zealous about cranking up the brightness very high (routinely 80%+). My battery life was more in line with my expectations today after the above changes. I had 3:30+ usage and twelve hours standby (according to the phone) consisting of fairly light wifi browsing, texting, and reading emails (some on 3G), and some calls (30 min) using Bluetooth. I had 50%+ battery left when I put my Sprint iPhone 4S with iOS6 back on the charger.
Might I ask what carrier you are using? There definitely is a big difference in battery life when on 3G (worse) compared to wifi. I imagine there is variance regarding carriers and of course signal strength as well.
In a nutshell, the new auto brightness routine coupled with perhaps the call network search going nuts using location services may be a couple of the big culprits people are looking for. I'll check it out for another few days and see how it goes. I will say that today was the first day that with my normal usage I did not feel there was any chance I was going to run out of juice. That was nice for a change!
Note that I did not have insane battery drain like some posters here, I just was getting around 5+ hours of light usage consistently on wifi. That number looks to be a couple of hours higher now. Fingers crossed......

Hello,
I was getting around 6 hours max on wifi mostly, even:
Using mostly wifi. Only using 3G a small bit when between home and work
Having bluetoith off (even though I want to we it)
Having location services off for most items
Having brightness around 35 percent with auto brightness on
Checking 4 mail accounts every 15 minutes (no push)
I have since bumped the mail settings up to 30 minutes, have disabled network cell search under location services/system(via another posters suggestion), and turned off auto brightness.
I'm still not totally happy with what I'm getting now, but auto brightness looks to me like a big part of the problem. It was very over zealous and would crank the brightness up to around 90 percent routinely on me. That will destroy the battery any day...
Thanks for posting back!

Methinks it's the brightness censor that's causing the battery drainage issues... even in low lighting, the screen lights up like a torch. I'd try de-activating Auto Brightness...
Admittedly not a "fix" but maybe it will improve battery life until an iOS fix is launched...................

I've noticed my 4S drains a lot more during a working day. It is now typically on 30-40% when I get home, whereas it used to be 75-85%. It seems to be related to using mobile data though. When I'm on Wifi all day, with the same usage pattern, it's about the same as iOS 5.
This could be coincidence because you never know what's going on with the local cell towers, although it's not losing signal, always full strength.

Mine got significantly worse. I was always at 6 hours 30 minutes to 7 hours of usage per day.
After iOS 6
I tried turning everything off and it didnt make much difference. So I did a restore. Tried it for a couple days and it seems a bit better.
I just turned off passbook's notifications and location setting to see if that helps some more. I hate having to disable crap to make my battery get me through the day.

I realize your display will appear to be dimmer than maybe you're used to, but pull the slider down to about 30%
It does wonders for battery life. I can now go a full day at least without charging. Previously could not get through a working day.
You might also want to uncheck any location services you don't use as well.
It took me a while to figure out that this gets around the problem.
It's strange because I've not changed any settings from iOS5.1.1, but who knows what goes on in the guts of iOS6
I'm on a 4S.
.
I've done all of those things and there is still a significant difference in battery life in comparison to iOS 5.
There must be something pulling it down. Try also changing the screen lock time to one minute.
I must say this is the frustration with iOS upgrades. A lot of unexpected behavior happens when really they shouldn't. The battery thing had me going for over a week.
The mail problem still has me frustrated. Works, but is flaky.
.
3 things I noticed after the upgrade.
1.
Will turn bluetooth setting on automatically, had no idea until I saw the icon for just a second after exiting a game. (Why the f does fruit ninja get to automatically turn on bluetooth?) So I turned off bluetooth in settings. Just a little bit battery from 5 on my 4S
2.
Will occasionally just not send a text message (iMessage or just SMS) even with full antennae.
3. Still can't delete or put newsstand in a folder (c'mon apple! wtf?) Passbook, maps, bad battery: who tested these things then greenlit them?
But all in all still one of my most prized possessions.

After having iOS 6 on my 4s for awhile now, I certainly haven't noticed any battery performance issues. With each version of iOS adding more and more features (and thus more things running the background), it is inevitable that there could be battery issues.
If you haven't updated your iPhone 4S's to iOS 6 GO SLOW because my experience with it was a huge debacle.
I upgraded as soon as the update showed up on my phone. Within a day, my phone was constantly warm and its battery would die within 3-4 hrs. I took it to an Apple Store in Chicago, where they replaced the battery.
The problem persisted, so I was back at that same Chicago Apple store 2 days later, where they swapped out my phone for a new phone. I foolishly had them update it to iOS 6 so I could restore from my last backup to iCloud.*
This time, I noticed the phone was crashing 4-5 times a day, requiring a hard reset to reboot the phone.*
I took it to a Seattle area Apple Store, where the genius there concluded that something in my iCloud backup was corrupted, so we did a complete erase and reset, and set up the phone as a virgin iPhone. I didn't add any non-Apple apps, but it still crapped out and hard crashed every few hours.*
So last Friday, I was back to the Apple store. This time, I convinced them that phone had a bad mother board or memory chip. They gave me yet another iPhone 4S, but this time when they asked me if I wanted to have it updated to iOS6, I said Hell No! and bolted out of there with iOS 5. Once you upgrade you can't go back to earlier versions.*
Well, since being back on iOS5, I'm back to having a reliable iPhone that runs all my aps and lasts all day.
I would wait a good long time before upgrading if I were you. They'll hopefully have most of the bugs ironed out by iOS 6.1.1.*

I have that feeling now aswell
There seems to be mixed reports on battery life. iPhone 4 devices appear to have more problems according to the posts here.
