But before rooting it's have huge proble of draining battery it's battery drains 25% within if screen off to 10-15min from 100% to 75% very fast. One day it got battery calibration problem to it showed 0% and still it was working... Then I went to sevice center and they formatted and installed th android 5.11 stock rom again they electrically tested said battery is okay but software problem or may be software draining it. As I googled and founded that some softwares setting consumes battery and to find them and kill or.force.stop.them and to cha he settings... Which switch off did ie. Developer option> windows animation scale / transaction animation scale/ animator duration scale This option and GPU rendering I turned off and Bluetooth WiFi off and background process limit to 2 in setting developer options which reduced the battery draing in off screen but still while using its draining to fast in compared to same company other model with same 3000mh battery. So after rooting I installed greenify and accu battery to solve the battery charging or draining problem still it's same.
