    Hi there,

    thx for the explanation..for today my battery life looks better..the soft reboot might have helped it.


    your right about "battery bug seems to occur mainly in sleep mode" the usage on MY phone shows, does not match the amount of time i using the iphone. Which it show more usage time than i have.

    Hi all,


    i'm following this thread to understand if my iPhone 4S has battery drain problem or other. My iPhone with iOS 5.0.1 has lost 10% of battery in half hour in idle, could be broken?

    I just got my new 4s on Tuesday. I was not having any battery drain issues until yesterday. I installed a Xbox Live app (360 Live) and by the end of the day the battery was pretty much drained, even though I was at work with my phone just sitting on my desk all day. After finding this post and knowing that the only change I had made was installing that app, I deleted it, closed all background apps and did a soft reboot. Battery life is back to normal. So I must agree that there are some apps that trigger this problem. Just thought I would share this so maybe it would be of use to others having battery issues.

    HI JM,


    Thanx for sharing your experience. Hopefully more and more 4S owners with pathetic battery performance can try this step and benefit from it


    Also: as we've been pointing out, this (close all apps + soft boot) is certainly not a final solution, but is just a workaround until Apple engineers can fix this problem for good



    With luck, you'll be able to 360-live again soon on your 4S!

    Hey sk0rp10,


    I got 4S 4 days back and I was wondering whether I got a faulty piece.


    this really worked for me. thank you very much!!

    my battery was showing 72% before this workaround. i followed the above steps and after 3 hrs, it still showed 72% and then i turned ON all the services except Siri and still after 1hr, it is showing 72% !!!


    you are the hero!

    I have noticed on my iPhone something different. When the wifi is turned on and after a 15min of standby for the iPhone, the wifi stops working to prevent battery drain. As a result, if you have 3G on, the device will switch automatically to 3G network in standby. However, when you wake the iPhone it will switch back to wifi, in lightning fast. So, turn off 3G when you don't need it
