What general methods do you usually use to optimize the performance of Android phones? For example, memory management, background process control, and system settings details?

Which system settings (like animation scale, background process limits, etc.) show significant performance differences across different phone models in real-world use? Are there any recommended scripts or tools to manage these parameters uniformly?

Thanks for sharing! For memory management, I usually disable unnecessary background services in Developer Options, lower the animation scale, and regularly clear caches using Greenify-like cleanup tools. If I need to further restrict background processes, I’ll also set "Background process limit" in system settings to "Standard" or lower. Have any of you encountered cases where certain apps were mistakenly killed, causing abnormal functions, when using these tools?

To improve the smoothness of Android systems, I usually start from three aspects: memory recovery, background process restriction, and animation rendering. 1. **Memory Management**: Use ADB shell `dumpsys meminfo <package>` to regularly check the memory usage of hot processes. After finding memory leak points, fix them at the code level (such as using `WeakReference` and timely calling `View.clear()`). For ordinary users, sleep tools without root like `Greenify` / `Nuro` can put long-unused apps into Doze mode without affecting normal use, significantly reducing background RAM usage. 2. **Background Process Control**: Adjust "Background process limit" to "At most 4 processes" in Developer Options to prevent OOM on low-end devices. For services that need to stay resident (such as email and instant messaging), use foreground Service with `START_STICKY`, and change other unimportant components to `JobScheduler` so that the system only schedules execution when the battery and network conditions are suitable. 3. **System Animation & Rendering**: By running `adb shell settings put global window_animation_scale 0.5`, `transition_animation_scale 0.5`, and `animator_duration_scale 0.5`, the animation speed is reduced to 0.5×, which can be directly felt in the improvement of UI response time. If the device is rooted, it is recommended to flash Magisk modules like "Viper4Android" or "Performance-Turbo". These modules will automatically adjust the CPU governor to `schedutil`/`interactive` and enable big-core short-term acceleration. Combined with temperature threshold tuning of `thermal-engine`, the overall frame rate will be more stable. Overall, first use ADB scripts (such as `adb shell pm list packages -3 | while read p; do dumpsys meminfo $p | grep TOTAL; done > mem_report.txt`) to generate memory reports and locate high-consumption processes. Then adjust processes and animations through Developer Options and the aforementioned rootless tools. If necessary, combine Magisk modules for CPU/thermal optimization. This process can achieve a 10%–15% smoothness improvement on most mid-to-low-end Android devices.
