Scarface. Level 1 Level 1

My iPhone 4s battery seems terrible! Almost equivalent to my 3GS and it's terrible battery life. When I got my iPhone yesterday and restored from backup I noticed nothing really changed with minimal usage and standby! Is this normal or should I consider setting it up as a new phone because maybe something is running in the background that's causing it to drop a percentage every few minutes under light usage? Input would be great!

Topic creator here with some VERY promising news, makes me even want to make a new topic to halt the hate about apple not doing anything! I managed to sneak a beta of 5.1 and so farrrrrrrrr, BATTERY LIFE HAS IMPROVED! I have been fiddling around on the main menu, settings, etc and it's still at the same percentage! I will continue to further test out more and see how the battery is. In the meantime, Everyone, hold tight for 5.1 because if this is the supposed cure, it's looking promising!

    Same here.  I checked and all my settings are similar to my iPhone 4 (i.e, bluetooth and ping off, brightness pretty low, etc.).  Seems to lose 1% every 3-4 minutes, even when locked/asleep.

    I tried turning Siri on and off, tried turning time zone on and off for location services - neither helped.  I let the battery run to 0% last night and let it charge all night in an attempt to condition it, we'll see how it goes today.


    I have AT&T, a guy in my office with Verizon has the exact same problem.  I'd rather not have to do a full restore as I would have a ton of work in setting up pages/favorites, etc.

    Hi I have an iPhone 4 and since putting iOS 5 on it the battery life has been really bad it drops at a ridiculous rate even when I'm not using it where as it would barely drop any charge when it was in standby. I've tried turning lots of thing off but it makes no difference. I've been looking around and alot of people seem to be reporting this.

  • JonGoldman Level 1 Level 1

    No difference after battery conditioning.  Burns about 15%/hour while asleep/locked.

  • mrbofus Level 1 Level 1

    Yikes! 15%/hour is pretty bad. My experience isn't that bad, but my iPhone 4S loses about 1%/hour when asleep and doing nothing. My iPhone 4, even on iOS 5, would only drop about 2% overnight but my iPhone 4S drops about 9-10%. And I've already calibrated the battery by letting it drain to 0% and then charging it all the way to 100%.


    The only differences between the iPhone 4 and the iPhone 4S are the camera, processor, antennas, and Siri. I can't imagine the camera is causing any difference in battery life nor the processor since the iPad didn't take a huge hit going from the A4 to the A5 in the iPad 2. And my iPad 2 running iOS 5 still gets great battery life. So unless I'm missing something, it's either the new antennas (and/or the software related to that), and/or it's Siri.

    In the 29 minutes since I last posted, I wrote one email, played one word in Words with Friends, one word in Hanging with Friends, read a few news articles in USA Today, and read some posts in Engadget. All on wifi, not 3G. My battery has gone from 89% to 77%. Dropping 12% every half hour means the phone will barely last over 4 hours of light usage, and that's not even making any calls!

  • JonGoldman Level 1 Level 1

    I'm more like 20% an hour right now with nothing going on.

  • richardfrombromley Level 1 Level 1

    same here have been using iPhone 4 and the battery has been OK but since getting the 4s I am experiencing terrible battery drain in comparison. I thought the battery was supposed to have a better battery? typing now with only 6% left where my iPhone 4 would have a about 40% under the same conditions.... very strange and not good in my humble opinion.

  • foreshay Level 1 Level 1

    I'm in the same situation.  My battery life is terrible.  I was imessaging my friend about it (on wi-fi) and over the course of 12-15 minutes I lost 10% battery life.  Only safari, phone, messages running in the background.  Do we contact apple directly or contact our service provider to complain?

  • JonGoldman Level 1 Level 1

    I'm holding for support now.  I tried turning location services off and loss 4% in 14 minutes, only thing I was doing was reading a book with the Kindle App.

  • sherry0618 Level 1 Level 1

    I lost 20% on my 4 overnight. I wonder if it has something to do with the wireless sync.

  • JonGoldman Level 1 Level 1

    Support was willing to send me a new phone, I am keeping the case open for a few days to see if there is an acknowledgement and/or forthcoming update.  I'd rather not have ot start over with a new phone.

  • cls24 Level 2 Level 2

    Has anyone figured anythiing out yet?  I did a full w/trickle charge last night to 100%  Today I used the phone maybe 1/2 hour or 45 minutes and I am down to 35% charge.  On my iPhone 4 I would charge every few days.  Seems with the iPhone 4s I will have to charge it every night or more.
