Android is the most popular mobile platform which is based on the Linux kernel. But their devices don't age well compared to the competition. Smartphones phones ship with a stock kernel configured to provide balanced performance. We have conducted experiments on Redmi K20 Pro (codenamed Raphael) with a few different kernels based on linux. We have noticed a variety of different performance and battery performances on different kernels by different developers. Some showed significant performance improvements and stable functioning with a minor increase in device temperature and reduced battery life.
