Q: iPhone 4s Battery Life?

I had the similar issue with iPhone 4S 16GB Black.  I got it replaced from Appe for a new one.  First day I didnt install any applications, emails etc but still the battery life was pathetic.  So I went ahead and changed following settings:

Go to Settings ---> Location Services ---> System Services ---> Turn Off Diagnostics & Usage, Location Based iAds and Setting Time Zone.

After that I restarted the iPhone, installed all applications, emails.  Today is second day after the settings changed, its around 2.30 PM PST and the iPhone 4S 16GB Black battery life is at 86% which is excellent.  Earlier it used to be around 50% and by evening 7 PM it would be around 10% and would shut down automatically. As of second day I see a really good battery life after changing above mentioned settings.   Hopefully my iPhone 4S battery life issues are gone with these changes.  Hope this helps others too.

May be of interest to everyone on this forum...at least they are trying to solve the problem...I suppose

I'm chiming in also for me then.  I thought it was normal but I drain 10% an hour if i decide to msg someone for 5 minutes within that hour.  I also trickled about 8% over night on standby.  That was only a 6 hour over night also, theres no way this phone will last 200 hours doing nothing.

Somebody needs to address this issue.

How does one re-download iOS5? I don't want to restore with the download I have.

And just to add some data.   My iPhone 4S 64GB ran out of power earlier today at work.   I let it charge to 100% and un-plugged it from the USB port.  It has been idle now since then -- no calls or text messages or app use for 1 hour 20 minutes (80 minutes); my battery life is at 92%.  I lose 1% every 10 minutes.

1% every 10 minutes == ~16 hours of standby time not 200 hours :-(

I've made an appointment at the store in the event that I have a hardware problem.   This is so astronomically far from the advertised battery life that I'm really hoping that whoever replaced Steve goes into the development lab and gives somebody a good scolding .... you know he would!

I had my 3GS for almost 3 years and I don't think it ever ran completely out of power ...

If one of the problems is in fact the restore process over-writing 4S settings with incompatible 3GS settings well that's just not even funny ... hardware and software vendors have to deal with upgrades all the time, this is just a no brainer ... what about a post-install script that checks for these over-written values and applies a fix ?   I don't think Apple would make such a basic error in not having any sort of QA over such a common process.

On my 3GS, WiFI and Bluetooth were always on and it didn't cause me any grief.  I have a car with bluetooth and I don't want to have to turn on/off bluetooth each time  I get in/out of my car ... that would be stupid.  Likewise I'm not going to toggle WiFI on/off just to conserve battery life like water in the Sahara.  If my phone is in standby mode, the WiFI use should be minimized to conserve power auto-magically ...

*sigh*

I hadn't even thought about this until I read about everyone else's problems.  I'm at 30% battery right now and with the iPhone 4 I'd be at 60% or higher this time of day.  If it's software, I'd assume we'd see a fix relatively soon -- sure hope so. 

I'm having the same issue... plus I've already returned my 4GS for a new one and it has the same problem... not sure why the battery is draining so much even with location services off. My wife's iPhone 4 doesn't have the same problem with a similiar configuration in iOS5.

"I have had several occasions where left plugged in all night the battery icon is at 100% then as soon as i unplug it drops to 97%, this morning it dropped to 99% just by unplugging. I have also had charge all night, but find it has only charged to 95-97%. Once it has been plugged back in it goes up to 100%."

Saw this too one morning...din't think much of it.

My iPhone 4S is also drainning the battery so quickly and even when I dont use it it keeps draining more than 10% for at least 40minutes to an 1hr.  At night when I dont use it after full charge when I wake up it is at least 50% to 60% even on standby.

Have the same problem with my iPhone. It lost over 40% battery life within 5 hours and I barelly used it. I called Apple Care today and they offered me a replacemnt but it seems that this won't be of any help considering how many people seem to have this problem too

What I noticed though is, that the phone seems to think it is on although it is in sleep mode. At least that's what I think because when I look into the usage data it shows 4h 20min of usage and I clearly did not use it that much - I was working!

I also got a new 4S and facing terrible issue with battery. every 2-3 min the battery is going down by 1-2%. I just use for some application and chat but getting poor battry back up.

I would go to apple store and check for this.

Any resolution or patch for sharing this would be appreciated.

OMG. This battery thing is KILLING ME.  Mine goes down to 80% by the time I finish my morning coffee.  I can almost see it move.  I am not doing anything THAT out of the ordinary.

APPLE please fix!!

there needs to be an app that access settings and allows user to turn off non essential functions such as location, 3g, data, bluetooth. a kind of sympathetic response to power scarce power resource. Does this app exist if not this is prior art.

the app should have a one button press activation.

any ideas guys, because my battery drains very quick.

I just got the new iPhone 4S and this battery does not last longer then my iPhone 4.  The battery life is horrible.  I checked the settings and anything that could stop the death drain.  Nothing seems to help.  PLEASE APPLE FIX MY PHONE.
