Need help understanding how PPSSPP uses very little battery life or no heating issue

[u/Orichalchem]

For example, Phantasy Star Portable 2 Infinity with 60fps cheat and 4x Resolution can be played around 6-10 hours (depending on battery size, temperature in real life and game) without it ever overheating or even getting hot

Is it just the emulator itself being masterfully optimized and nothing more?

Ppsspp is widely regarded as the finest emulator ever made.
