iOS 6 iPhone 4s battery drain

ugghhh should have not upgraded, seems when my phone says its at 100 percent unplugged form car charger, walk into work though forgot to turn off wifi, but have all the other junk turned off to save battery from previos ios5 fiasco, and in 15 minutes my battery went from 100 to 83 percent. what in the world is that about? thats even worse then the htc evo pojunk. even though ios5 was pretty battery hungry its never been that bad..... is that whats to be expected from nowon? less battery power from every ios upddate? with wifi off it seems to still drain pretty bad, not as bad but still worse then the junky evo.

Hi guys,

I see everyone is talking about the battery draining fast, I have the same problem. But I was wondering if you feel that your phone is overheating compared to how it used to be. I never haa a case and I know how warm the back used to be, now it's close to being hot 😮...

Is anyone else having the same issue?

I am also having battery issues on my iPhone 4S and iPad (3rd generation). I have been using my iPad for only 3 hours and am down to about %50 when usually I can go from 7:30-5:30 and get down to maybe %50. I hope that this is something that can get resolved quickly by apple

I've got to be honest, I came looking for a topic to see if anyone had noticed a bump in battery life! I've had no such drainage problems I'm afraid - if anything my battery is behaving much better and I was surprised by that.

So you are saying for those 3 hours you did not try some of the new features out like maps or anything else? You are telling me you upgraded then put the phone to sleep? Come on most people including myself played with the new features for a while after upgrading which will drain the battery. I had 50% left after 3.5 hours usage. That puts me on the track for 7 hours of usage (which was heavy btw) which puts it on track with what apple says it should do.

As soon as I updated last night I noticed the excessive drain today. It's been off charge since 8am and it's now 1pm, it's currently on 50%. Normally at this time of the day it would be on around 80-85% still. Something definitely isn't right. It's just sat there idling with wifi enabled just like it always does and it has 3 bars of cellular signal. No other settings have been changed as I've not had time to play with it.

3 bars of cellular service is a key indicator there. The radio will have to go to a higher power setting to maintain link with the tower because the signal is getting weak. The higher power the radio is the more battery the phone uses.

That maybe so but it's no different to iOS 5 from yesterday which only drained to about 70-75% when I got home.

Turning off location services appears to have made a huge difference, and I'm wondering if it's compas calibration causing it. I'm currently testing this idea too by turning it off but leaving the other location services on.

Yep - battery drain here as well. Take a look at this:

If someone can confirm, it might help to pin this down. Thanks.

Not an issue. I think that guy is worried about nothing because I can't replicate what he is talking about on my phone. The sensor is not flashing at all when I lock my phone. He probably has bad hardware.

Yeah mine is too. We always get these battery threads after an update. Most are fixed by a restore or reset. Most are just paranoid they are not getting that extra 2 min they used to on the phone. My phone as I pulled it off the charger this moring is reading under usage as:

100% charge

12 min of usage

1 hr 20 min standby.

That means it has been off the charger for 1 hr 20 min. I have push on, notifications on, locations services on and just about anything I use a smartphone for on.

Looks like I found the problem on my phone - Google latitude. It's excessively querying for the location. Disabling it seems to return the usage to normal but I'll keep testing.

It could be. I never turn compass calibration on since I don't use that feature much.

What is google latitude? Is it an app you were using?

I'm going to join in the 'happy' crowd here - my battery life on my 4S has dramatically increased since the IOS6 upgrade. I have pretty much everything turned on - wifi, bluetooth, icloud - the whole 9 yards. I'm used to my battery getting down to about 80% by noon from a full charge overnight. Today I'm looking at 94% instead of the customary 80%. So thumbs up from me.

I have same issue here.

I have iphone 4S and I did full restore (OPTION + RESTORE), after that I choose New iPhone and not restored backup.

I did every thing that a read including RESET NETWORKING, RESET FACTORY, RESET *.*.

Hi,

I got hte same problem of heating! Just upgraded to i6.0 this morning on my iphone 4 and the phone's been hot then warm till now!
