The battery drain on my moto E2 2nd gen 4g LTE. is huge in the past few days. Android system is using about 60% and while in the standby mode the CPU is still awake.... I have charged untill 100%but when its in 75% it is automatically shutdown itself....... awa it's heating so much rapidly.......So any help in this issue is deeply appreciable....
