Hi,
My N5 heat up quite bad when playing Plants vs Zombies 2. The heat coming from the top part of the phone, the back and front, screen heats up.

Is it due to the game or something else.
10 to 15 minutes of gaming, the phone heats up to quite a worrying state. Even stop and put back the phone in pocket can feel the heat.

Any comments

Based on battery doctor apps, the battery temp is 48.4 Celsius.
Everything stock. Not sure where to see the processor temp.
This is about 10 minutes gaming on plant vs zombies.
Battery drain from 53% to 38%.

Will try other games and see how.
