Re: Facing problems with abnormal battery % ?

[gokhalesubodh]

I did factory data reset, uninstalled  Mcafee, still no positive result

I also did pressing power and volume up button for 10 seconds and restarting the phone, still the problem is not resloved

I repaired the phone through SUS, still i am facing the same issue....

I activeted stamina mode and Low battery mode, still there is no improvement

I have purchased this phone on November 2012 and after 3 months phones speakers were not working

So I had to go to the service center. After this issue was resolved, I am facing the battery issue.

I am fed up with these issues...

can anybody provide me a permanent solution for the battery? is this the software issue or battery issue? and if this is the battery issue, what am i supposed to do. I mean battery will be replaced or not since it is inbuilt with the phone....My phone is still in warrenty period

and here is the snapshot of the battery consumption
