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.
your iPhone is certainly experiencing an abnormal discharge rate, which is about 6x the normal one.
However it is not "broken" , simply one of the Apps that were launched on it accessed the bugged part of
iOS. This event triggered the resource release bug. To stop drainage just follow the steps suggested few posts before ( close all apps , then soft reboot ).
This is obviously not a solution to the problem , which has to be fixed by Apple, rather than a simple workaround which can let you use the iPhone as normally as possible.
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.
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!
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
