I'm an indie developer working on a 2D pixel art game for mobile, and while it runs smoothly on my current test devices, I'm getting reports of significant performance drops and battery drain on older phones, especially during scenes with multiple particle effects. I'm using a popular game engine and I know I need to dive into mobile game optimization, but I'm not sure where to start profiling my bottlenecks. For developers who have optimized for a wide range of Android and iOS hardware, what are the most impactful first steps? Should I focus on reducing draw calls, implementing object pooling more aggressively, or downgrading texture resolutions dynamically? How do you balance visual quality with performance, and what tools or profiler metrics gave you the biggest clues about what was causing frame rate stutters or excessive memory usage on lower-end devices?

Start with profiling on the devices your players actually own. Turn on a real-device FPS monitor and run a typical scene with heavy particles. Use the engine’s profiler to snapshot CPU/GPU frame times, memory allocations, and GC spikes. Try a 60-second profiling session on a representative device (mid-range Android, older iPhone).
