iOS 6 iPhone 4s battery drain

Hi all,

I have seen this on my 4s with io6.1 as of beta 5 as well.

Because I'd seen this behaviour before after an app update, I turned off tunein radio app access to location services and as of this morning and I still over 90% baterry after 5 hours in comparison to yesterday where it was already below 40%.

I'll repost tomorrow and let you know if this continues to be the case.

Anyone else disappointed that the release of iOS 6.1 doesn't list (and obviously include) a fix for this? I did notice that after man of my apps updated the battery drain started to disappear. However, the company I work for just switched to Exchange email services and now my iPhone 4S drains if I have is set to Fetch, so I set it back to manual and the drain disappeared.

Hi all,

Just want to share some of my experience with all the frustrated people here. Good news is that I seems to have found a solution to my battery draining problem.

I have an iPhone 4, and I updated to iOS 6.0.1 last Tuesday(unknowing what I was getting myself into). I found out the next day that the phone's battery was draining away at a rapid speed, and it ran out of battery after 4 hours of a full charge! I was appauled! Then I came to this forum and saw people offering different solutions.

I tried to reset the phone as someone suggested, but it didn't help. The phone was still draining the battery.

Then I saw somebody suggesting re-setting all the email accounts (deleting and then re-adding), I tried it, voilà! It worked instantly! I still have 41% after a whole day today!

Give it a try if you are still rather frustrated as I was! (I almost smashed the phone severals times...)

Unbelievable Results !

Update 2

After I fixed the issue with my iPhone , I decided to update my wife's iPhone .

She also came up with the same issue and limitAdtracking didn't work for her.

But what worked on her device is the following :

1) Turn off calendar notification , keeping alerts , and view in lock screen on.

2) turned off alerts for new event in the calendar (settings > mails, contacts,calendars)

3) Turned off shared calendar update( I will try to switch this on later as part I second test )

Results :

1) phone charged 100% on Friday midnight .

2) 1hour 10mins of iPod music, temple run 2, social networking , emails, browsing , hardly 30mins of call.

3) battery left 45%

4) usage time 5hours 52mins

5) stand by time 1day 6hours

I thing I have been lucky (may be ) . Both the phones are comparatively new bought after the arrival of iPhone 5.

Try this out.

All the best, do share the updates

hi again,

haven't charged my 4s in 24hours and after deactivating the location service for tunein radio app, my 4s still has 72% battery, usage 2h, 7min, standby 1 day, 1 hour.

Bug in os6.1 or in apps?

Cheers.

I think it's probably a bug in the app and in 6.1! However I blame Apple and 6.x because this all worked previously.

From all the evidence on here it seems that 6.x is much less tolerant than 5.x to the way apps use location services and also to push notifications. They seem to be the biggest culprits of the battery drain issues with 6.x. However it's undeniable that NONE of these existing in 5.x so Apple certainly broke things badly with 6.x which is unforgiveable after all this time that it's still unfixed.

For those Linux fans out there, look at how Linus Torvalds berates kernel developers when they do anything to the kernel that breaks existing user applications. In my view that's the approach Apple should be taking instead of making such a mess of this and then even worse, staying completely silent about it and refusing to implement any fixes even after several releases with the opportunity to do so.

It has destroyed my confidence in Apple's software. My wife doesn't want her (currently working) iPhone 5 on 6.0.2 to be updated as she doesn't trust that Apple's code won't break anything and worst that they don't care enough about customers to fix it.

Guys, Sbailey4 found a solution that works for me (I own an Ipod Touch 4th generation).

Try this:

Quoating Sbailey4:

Follow as written. If no help look to restore via iTunes as a next step. And dont restore your backup. That could put the problem right back in. Test it and see how it works.

1: Reset all settings (settings>general>reset (NOT ERASE ALL SETTINGS)

2 a. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)

2 b. If you do not get the complete new setup screen with language setup and setup as new phone or restore from iTune/iCloud backup, be sure to go back to #1 and reset all settings again (it should happen the second time)

3. Turn off system location services timezone and iAd (settings -> location services -> system services)

4. Fully discharge battery (until you get the spinning wheel and it shuts off)

5. Fully recharge battery (overnight if possible)

Hey guys, so I've been having a strange problem charging my iPhone 4S the last few nights. I plug it in to charge and it does it as normal but when I wake up my battery is at 1%. Any ideas on what I could do to fix this or what the problem could be? Thanks in advance!!

iPhone 4S, iOS 6.1

I had the same problem, except my battery was declining by percentages evey 30 seconds, until it reched 1%. When it reached one percent it didnt die, and i could use it all day as if i had full battery. Each time i try to back it up or reboot/restart it however my iphone goes onto the charging battery screen, and wont change, wont reboot/restart, wont restore. It cant be recognized by my computer during these episodes, and takes HOURS to wake up again. The red on the battery screen does not move, and my iphone insists that i still only have one percent battery.

Exchange email hung up? iCloud hung? Something clearly is running non stop IF as you say teh charger is working as normal. I would delete the exchange email accounts, reboot and add them back. Maybe wait and see if the issue goes away before you add them back. Exchange email is know for getting hung up and draining battery. Also may want to disable iCloud if the email doesnt solve it. Also if its still running just reporting 1% as TheGlassAddiction just reported, its probably a calibration issue. Let it run until it cuts itself off (spinning gear), Then charge it back up unattended for at least 1.5 hrs after it shows 100%.

Run the calibration and see if it solves your issue. Let it drain until it totally shuts itself down, then charge back up unattended for at least 1.5 hrs after it shows 100% (or overnight)

I just realized the Hardware Model is catogorized as "iPhone3.1" (my is iPhone 4) by the new iOS6.1 (10B144) and it generated lots of messages ( Settings>General>About>Diagnostics & Usage). Will that be an issue or that's normal?

normal to have lot of messages in there but may want to see what some of them are. May be an obvious issue causing a problem.

My phone is now switching off at 32% battery. Anyone else had that problem?

No I have not. But that seems weird. Did you try doing a Hard Reset: Hold down the sleep/wake and home buttons for at least 10 sec. or until Apple logo appears.
