This script will increase battery life of your Moto E. All you need is root access on Moto E and Smanager for this to work.
What this script does?
When your phone is in AWAKE state:
Governor = Interactive
Max = 1190000
Min = 300000
When your phone is in SLEEP state:
Governor = OnDemand
Max = 300000
Min = 300000
So basically this script automatically changes governor,min & max freq and more depending on your phone’s state which results in saving battery to great extent.
First download the script to the root of your sdcard; open SManager and navigate to the script; select the script; click on Su and boot button; select Save and reboot your phone.
