Moon-reader was taking to much battery. I switched to an older version that works great
Moon-Reader-Pro-5_2_6
I switched to No Launcher Only.apk because the other was taking battery.
In dev options there are two boxes at the bottom to have only one app work at a time.
This works really great. I'm 16 days in with 25% battery life still left.
