Xiaomi Redmi Note 2

[csc12345678]

Just updated the redmi note 2 miui 8.5.1.0 running quite smooth and helps with slowing down the battery consumption

This redmi note 2 is it having battery drain issue in miui8? Or best to stay at miui 7.1.1.

Mine is MIUI 7.0.8.0. Recently notice that phone is getting warmer. But battery temperature says 23 degrees C !

I notice that the heat does not come from the battery but above the battery, closer to the camera.

Any idea what's the problem ? Would a hard reset solve this ?

Thanks for your help in advance.
