I am living in Qatar and recently I bought a Nokia 6 mobile from one of the online shops here Discountsqatar. It is okay for 3 to 5 weeks but after that, it starts to get drain the battery so fast. I removed too many background applications and reset the phone. It's been okay for 2 weeks but it again starts to drain the battery.
I return the phone to the Customer Care and they told me that an app that I installed is working background and draining the battery.
Is there is any solution for this kind of problem? Please help me.
Please suggest some solution to the problem...
