    Great app.. If it ain't working for you, then you simply do not know what you're doing and what you are actually missing out on.. You think android batt drain sucks? Well then, you still haven't met One Power Guard..

    I've tried other apps that "Claim" to work, but this one actually and truly works! I'm on a Nexus 4 with a horrible battery and I used to only get to evening before it died, now if I'm careful I can get up to 3 days! Also, for people who think it doesn't help, turn off WiFi! It helps a lot...
