I came from the SGS4 and just got my new HTC One M8 a few days ago
I noticed this phone has "sleep mode" and wondered if that basically does the same thing as BatteryGuru.
BatteryGuru really helped on the S4 but this phone stock already has superior battery life than the S4 with BatteryGuru.
Will activating sleep mode and using BatteryGuru conflict with each other?
Should I even bother to use BatteryGuru since this phone has sleep mode?
Appreciate any and all opinions/recommendations
