Does this exist?
I too am having battery issues, I am rooted and have Juice Defender , SET CPU, LTE on/off and other apps to try to help battery life. I like SET CPU's interface in having profiles for Charging via pack, vs charge via usb, via screen on, etc. Juice Defenders is too complicated imho.
I'd like a program to do the following each configurable:
1 - plugged into ac - max CPU, Max screen (on), LTE on.
2 - plugged into USB - mid CPU, Mid Screen, LTE OFF,
3 - on Battery Screen On - LTE Off/CDMA on, Mid CPU Mid Screen .
4 - on Battery Screen Off - LTE off/CDMAon, CPU low
5 - on Battery voltage below 25% - CPU lowest, Data Off
Love the phone, just hate that I get 3 hours battery out of it...
