iOS 6 iPhone 4s battery drain

I downloaded ios 6 yesterday afternoon. Charged to 100% around 1 am and went to bed. I had an alarm set for 7:15 am but it didnt go off. So in about 7 hrs all the battery was drained. Then i charged the phone in class to 70%, in around 3 hrs of just standby and checking 3 messages, the battery went down to 20%. Plus my phone was very warm even just on standby.

Just wanted to add my story. Hopefully someone can fix this.

Yes me too. After upgrade to ios 6 my iphone 4 battery draining crazy & I have to charge the phone more frequently. Do hope that this can be fix soon 😟

After restarting I tried to get my iPhone into the state where the battery started dropping like a rock and so far I haven't been able to. I tried Maps, Camera, Calendar and Siri and battery seems to be dropping at a reasonable rate. I managed to get the sociald process running (it seems to be related to the built in Twitter/Facebook functionality), but I haven't yet figured out how to get absinthend.n94 to run.

That makes me think absinthend.n94 is the process that was killing the battery.

On a side note, GPS seems to cause a much bigger drain under iOS 6 than earlier versions. When using an app that uses location services the battery drops about 1% a minute. That woud kill the battery in under 2 hours.

Worked for me

Hi,

I am also experiencing an extremely fast drain of battery power. I updated my iPhone 4s via WIFI. In normal use I loose approx. 1% every 3 minutes. I then reset the phone to factory defaults (erased all data) and restored it via iTunes backup. Unfortunately the fast battery drain is back again. A normal reset (power + home button) didn’t resolve the problem either. Did anyone who experienced the problem erase the phone and set it up manually from scratch already?

Best regards, Daniel

Dear All,

To me this is just crazy, as if Apple didn't learn from past mistakes. My battery is going down the drain as I write this post.

This is really bad. Maybe I should switch to Samsung or HTC after all.

Cheers from Europe!

PS: Apple this is REALLY BAD - IT'S SUPER BAD! And I am really disappointed!!!!

Having the same issue!!! .. extremely fast drain of battery.

30% gone without doing ANYTHING.

Gosh!!!!

I had this problem with iOS5, read in apple support to back up and restore my iphone. Did that and it solved the problem?

Talked to a Genius

He recommended a DFU restore to try and resolve the battery issues, anyone else been advised this?

BTW

Techwrekfix's nor the one about resetting settings seem to have worked :\

I Have already tried a full erase and reset using just the phone and from iTunes

both times I set up as new phone and nothing, still having horrible battery life.

As a long time Apple supporter (since power pc) I'm really starting to get frustrated with Apple

if I wanted a phone with horrible battery life I would have gone with just about any Android phone

sad thing is my battery life is quite a bit worse then some of the newer Android phones friends and family have.

WIth competition stiffer then ever just not a good move on Apples part not a good move at all... :/

I Honestly expected a lot better from Apple especially after the ios 5 battery nightmare.. **** you Apple **** you

What is a DFU restore??

This may be an interesting tidbit. My iPhone developed battery when on wifi after the ios5 update. I was losing 3-4% or more per hour in standby. My ipad3 recently developed this problem about 1.5 weeks ago. Ios6 seems to have fixed this problem. My phone drained only 1% last night and iPad did not drain at all.

Investigating this further I went into Settings -> General -> About -> Diagnostics & Usage -> Diagnostics & Usage Data ->

When I scrolled down the list I found that lots and lots of entries titled "webbookmarksd_2012-09…"

I turned off iCloud Safari syncing and then went into the bookmarks on Safari and clicked on 'Edit' in order to delete the bookmarks but I keep getting the message "Bookmarks are being synced. Please edit the bookmarks once syncing has completed." Sometimes edit appears to work but when I try to delete a bookmark the delete button doesn't do anything.

This all seems like it might be heavily related to my battery problems.

Had the same problem apparently the new iOS comes with satellite navigation so it drains battery power turn off location settings and it will fix the problem until apple can.
