So i have purchased the device in November. I have constant battery drainage issue on the device. i only get upto 6hours of battery backup.
i am charging it if it's below 15% and removing it after it's 100%.
Tried battery calibration, no-go.
tried with different chargers, no-go
Checked in settings and battery is completely fine.
Coming to usage, i use wifi more often then mobile data to understand issue and tried without wifi or mobile data for a week, no-go. i am not a heavy user, i use device for calls/messages/social networks/writing and very rarely games.
If you have any suggestions or advice then i am all ears.
Also wanted to tell that device restarts on it's own sometimes.
