Optimizing Android games performance
summary
Use Systrace to find four concrete problems and fixes: single-threaded Unity render loops that hog one of eight cores (enable multi-threaded rendering), per-cluster voltage/frequency on Snapdragon 855 causing thermal throttling, frame-pacing jitter fixed with the Android Frame Pacing API, and GPU overdraw on 3K×1440 (four megapixels) — render to a smaller target to save about 58% of pixels. Benchmarks show lower power, fewer throttles, and stable 30 fps when these changes are applied.
