Description
I noticed high battery consumption in RetroArch compared to standalone emulators, this happens in both stable / unstable release
My config:
Switch 21.2.0
Atmosphere 1.10.2
Original Microsd 256gb
Few examples:
- mgba core consumes 15-20% more than pgba (mgba fork) emu
- Snes9x core consumes 10~12% more than psnes (snes9x fork) emu
- Gen plusx gx consumes 10-20% more than pgnen (Gen plusx gx fork) emu
- Pcsx rearmed consumes 20-25% more than duckstation port

Research direction
Start by reproducing the battery drain on Nintendo Switch 21.2.0 with RetroArch 1.22.2/nightly, then compare the listed cores with their standalone counterparts under consistent conditions. Measure consumption and collect relevant logs or profiling data. Done means the source of the difference is identified and a reproducible fix or clear diagnosis is documented.
