The difference between Android system and Android OS in power consumption ranking
In Security-Battery&performance, there will be Android system and Android OS, whose literal meaning is the same, but the two are different. The Android system is a service integrated with the upper layer. For example, the UI interface is included in it, so the power consumption will be large.
Android OS is mainly responsible for the work of the underlying services, and mainly controls the work of the system kernel, such as the allocation of CPU and memory and the release of resources.
