Does it burn when gaming? Intense gaming?
Otherwise, I do not see any reason for it to give up unless its a inherent QC problem.
Nope
It doesn't get at warm as my OPPO find n6 (up to 49°c)
Once in a while it gets warm but not to an uncomfortable feeling
That's usually when I leave it on for auto farming
Probably at best up to 30 mins and I'll check in on the game before letting it go back to auto farming (rinse and repeat this cycle for 2 to 3 times at max)
Frequency of cycle is around max 3 days a week
