Im on the system file w 52,xxx.. The other one is 50,xxx. Both ove them are reporting good battery life for me...
Everything is up to date except the roots file which is the one from tha 18th.
One thing that i see whatever you do on the windows side ove the board it reflects it on the android part so idk if this would really help out but ever since i downloaded these files...
