Battery usage has always been a top concern for smartphone enthusiasts. As more and more applications increase, people need to charge at least twice a day. This also causes the battery problem to be thrown to the Cusp again. To this end, the android team provided a series of "courses" for its developers to teach some smart phone power-saving tips, such as how to
