Q: iOS 6 iPhone 4s battery drain

I had iOS 5.1.1 on my iPhone 4 and at the end of the day I usually had 50% left, there were days where I didn't even charge it. Then I upgraded to iOS 6 and the battery life was horrible. I then bought the iPhone 5 hoping that maybe it would get better battery life, but it's worse. I've had to charge it once already today (after a full charge last night) and all I've done is texting.

iOS 6 needs a fix now!

Sounds like you either have a background app running or you're in a low signal area where the phone has to use lots of power to stay in touch with your local cell tower.

Had this same problem.

There has to be some bug regarding icloud.  I ended up deleting my iclould data on the phone.  It's not enough to disable the individual apps.

I used an app called "dataman" to watch as my data usage would tick up by .1 MB every minute or so.  After doing a bunch of research and trying different approaches, I found deleting the icloud data from the phone stops the data drain AND fixes the battery drain.

All your info is still in the cloud, so you can still re-enable it once Apple issues an update!

Good Luck!

What is wrong with Apple? My wife iphone 4s after the update to ios6 the battery is draining like crazy. My wife is about to kill me if apple doesn't bring a solution for this soon.. Besides I've followed all the steps and suggestions posted recently but still no cure. HELP is all i'm asking for!

How do you delete the iCloud data from the phone? I'd like to help my wife out as her phone drains to about 50% just sitting in her office. She doesn't even use the phone during work hours. We updated to iOS 6 at the same time. My phone is exacly the same as her 4S. I use mine during the course of the day and have plenty of battery left at the end of the day. As far as I can tell we have mostly the same settings??? This makes little sense.

Settings > iCloud > Scroll to bottom of page and click red 'delete account button"

I would then go to Settings > General > Scroll to bottom to reset and click reset all settings. 

(Your media and files will stay intact, but you will need to redo some preferances like brightness settings, etc)

Hope this helps, was driving be crazy too!

Thanks I'll give it a shot.

I had the same issue with iPhone 4S. Disabling of 3G helped to recover normal battery consumption.

I'll try not to repeat what everyone has been saying for 56 pages but I too have had horrible battery life on my 4S since upgrading to iOS6.  I've tried all the suggested fixes, and draining and recharging, and soft and hard restarts etc, still no luck.  I had great battery life before the update, and I'm a heavy user. I think something major that is going on in iOS6 is the IR sensor for Siri. It's always on when the phone is in use (you can see this by looking at your phone through a webcam) and I've noticed that even after disabling "Raise to Speak" or even shutting off Siri entirely, its still blinking and I'm sure that drains the battery. Any new suggestions or fixes?  I'm willing to try anything!!  Also, I want to be able to keep using my iPhone as an iPhone and not a paperweight, so I'm not really willing to turn off features like 3G (4G) or deleting apps I use every day.  I'm sure most users feel the same!

Add me to the list of folks who had GREAT battery life on my 4S before upgrade to IOS6.  Now I can't get through a day.  And turning off previously used feautures in order to live with an upgrade isn't acceptable.  Apple needs to fix this.  So sad...

I thought that I had much better battery life as well, but today I let the battery run down to do a full charge.  My iPhone 4S turned off when the % dropped to 22% on iOS6 like it used to at 1% for iOS5.  I'm thinking the % is way off in this version.  My battery % seems to jump around at times.  Barely goes down or ramps up on charging for a few minutes, but not better if it turns off at 22%.  Anyone here drained their battery fully?  Everyone is complaining about battery drain, but when does your phone actually turn off?

I guess we should all report the bug here

More bug reports can stimulate Apple to do something with the problem

Same problem.Very low battery.

I hope that Apple will soon solve the problem.
I do not want to disable "Siri" or "maps" to solve the problem.....i bought the Iphone 4s to use it as a smartphone, not as a normal phone.

I have the same issue as everybody -- tried all the fixes. Obviously it's iOS 6.

Just want to have a voice counted so Apple folks know how many of us are affected.

I'm a big Apple fan, but this one was highly disappointing. Don't know how they couldn't have figured this out in Beta testing... and still pushed it through? Almost feels like a "forced" hardware upgrade. Not cool.
