What are everyone's thoughts on the system compatibility, performance, and long-term value of older mobile devices? In today's fast-evolving app ecosystem, can old devices still meet daily needs, and is it worth keeping or upgrading them?

I bought that old Android phone back in 2016, originally just as a backup device, but after two years of use, system updates started causing lag. The first time I flashed an official OTA update, CPU usage shot up to 90%, and chat apps opened so slowly it felt like loading a webpage. Later, I decided to flash a third-party ROM—a lightweight AOSP-based system—and disabled unnecessary animations and background services. I also TRIM-optimized the system partition, and the lag basically disappeared. Now, daily chatting, browsing, and even watching 720p videos run smoothly. Battery degradation was another issue, so I replaced the original battery with a used one of similar capacity, restoring battery life to about half of what it was. The investment was far cheaper than buying a new phone. To extend its lifespan, I reduced system updates to once every six months, keeping only security patches to avoid frequent compatibility issues. On the app side, I use lightweight browsers and ad-free chat clients, regularly clear cache, and disable auto-sync. This keeps basic needs covered while reducing e-waste—balancing performance and eco-friendliness. Overall, as long as the hardware can still handle basic tasks, proper system tweaking and hardware maintenance can keep an old device running for years.
