Q: iOS 6 iPhone 4s battery drain

To be honest with you my phone after IOS6 update consuming less energy than before.

It was removed from charger 1 day and 8 hours ago,  usage was 6 hours and 7 minutes

(calls, surfing on the web, try the new features, listening to music), now it is on 53%.

only 3G was swithed off, and I did only what Techwrekfix proposed.

Wifi is on, Siri is on, iCloud sync is on.

I agree that iTunes Match probably contributed to some of the chaos in the IOS6 upgrade. I believe that's why my iphone 4S settled down quite a bit after spending the night in the charger – it cleaned up some of the iTunes Match mess overnight and seems better today. My 4S is not draining as quickly now and I plan to let it die completely before charging it tonight based on comments in this thread.

I restored my ipad 3 and it is holding it's charge nicely today.

Ok, I feel a little better knowing I'm not the only one experiencing this issue of battery usage being abismal. I downloaded iOS 6 yesterday, almost exactly 24 hours ago, and I've had to charge my phone 3 times. I've unistalled apps, I've turned off **** near everything; only things that are on are WiFi and Data, only notifications are phone and messages, if it has an on/off setting, it's off. I'm experienceing a useage of 1% approx ever 3-5 minutes, with or with out useage. Has anyone found any way to reverse this? Has anyone heard anything from Apple? This is worse than the first HTC Evo 4G I had, and that's saying alot.

I'm running an iPhone 4, as previously stated.

Now I did a full restore and back up restore, disabled safari iCloud sync, notifications, passbook sync, cellular data for the aforementioned. Reset settings etc.

Phones battery is pretty reasonable actually :)

But, as soon as Facebook was launched, I lost about 1% every 3 minutes or so, reading through the post it seems Facebook is a likely culprit, not sure if I should disable it or not. The Facebook app normally chews through battery anyway so I am not sure if this is a new glitch or the summation of the two Facebook glitches (ios and app) 

Anyone else getting this?

Reading all of your comments and experiments same thing PLUS one other strange behaviour:

After upgrading to IOS6, 3 times that ma iphone is shutdowning at 25-20% of battery!

After that if I try to start again, it tells me to connect to power...

When connecting to power it start right after connecting and show me like 20% of battery...

Someone has experimented the same issue on IOS6?

I have experienced something similar - my phone shuts down at approximately 4%.

I'm not great with the technical stuff but I'm having the same issues as everyone posting in this forum. I called tech support and they confirmed that the battery drain is a known issue. This is plain inconvenient. Bottom line is that on the old operating system, everything was dandy. Currently, I can't use my 4s to truly explore the new operating systems features before it dies. Realistically, I don't feel that I should have to disable features that I had enabled on the previous version to save battery, as it was never an issue before... Siri, location settings, screen brightness was all on full throttle and my battery would last all day with moderate tweeting/FB action throughout the day. Now, I'm @ 100% at 4:45 am, and showing 40% by 10:00 am. Previously I'd be at least at 70-80% depending on usage of course. HELP APPLE!!

Possible Temporary Solution:

I followed this and other threads.  Tried many things.  I tried everything others mentioned except a full wipe and restore, as that didn't work for many anyways (some said it did).

Some people were pointing to processes started by Safari that kept running.  So I figured why not disable Safari from starting.

Goto:  Settings --> General --> Restrictions

Turn on Restrictions (make sure not to forget your restrictions passcode)

Disable Safari (I have everything enabled but Safari).

Then exit out of settings and do a reboot (your settings won't be lost)

Do this by:  Hold rectangular button on top and circle button on front for 10 seconds or so until it powers off

Wait a few seconds and turn it back on.

Now Safari can't start, so if my theory is correct, neither can the other things with it causing trouble.

No browser???   Try Google Chrome or Puffin Free (which will also load Adobe Flash sites).

Please post results if this works for anyone else. 

I think I didn't make it clear that this seems to have solved the problem with my iPhone 4S.

Did they offer any advice since its a known issue?

Hi,

Same probleme here on iPhone 4s.

It's a shame ... we need a fix as soon as possible.

Best regards

Yeah I've noticed that my battery life is signifcantly worse with ios6. I know have to charge my phone at least twice a day. I'm hoping that they fix this soon

I experienced a similar issue after the update to iOS 5 on my iPhone 4.  The solution, for me, was to do a full charge/discharge cycle.  Let the battery fully discharge so the phone shuts down.  Then do a full charge using the plug-in charger (not USB).  "rinse and repeat as necessary"

This may or may not help what you'all are experiencing (can't test it myself yet because I'm still on the iPhone 4).  But it's one thing to try ...

same problem here.  Fully charged on my way to a soccer game.  Left the phone in the car and an hour and a half later whan i got it the battery was less than 20%  very frustrating.  Not too excited about trying a full wipe and restart as this does not seem to be the end all fix.  Wish i had waited to upgrade.  will try the full battery discharge and hopfuly this will work.  At this rate it will only take a half our or so. 

same here,

plz reply asap

I updated my phone 2 hours and 7 minutes ago.  When the update was finished, my phone's charge was at 100%.  After 127 minutes, I'm down to 76%.  Sad face.

plz reply

urgently asap
