@bassop your problem is a typical description of throttling caused by overheating.

This is not a ppsspp issue, but your device flawed design, which apparently does not radiate heat fast enough to run at high performance for a longer periods of time.

Nothing much you can do, other than playing less demanding games or trying hacks/frameskip to play with less power, you could also mod your device with better heat radiation or some kind of cooling system, but that's usually not possible with mobiles.
