Author introduction, Linux kernel has a set of their own management mechanism, one of the core ideas is that useless memory is wasted.
Here the memory that RAM. The purpose of the latter is to help you store photos, videos, music, install APP, while the former use is to stay in the use of APP, speed up the start speed.
On the contrary, if you always clean up the memory, not only the efficiency of multi-task switching greatly reduced, and APP repeatedly reloads the instantaneous power consumption higher.
Of course, this does not mean that manufacturers of memory acceleration on the useless, the only thing you need to use the scene is, APP no response/crash, or long-term load is not the case, in the event of the above, please bring up the background, these APP “clean out”.
