Twice as good as Battery Doctor This app has been great at extending my battery life. Was getting tired of BD telling me I needed to optimize about every 20 minutes and then giving me the same list of 36 apps that were draining power and claiming it shut them down. I figured it wasn't doing anything. So I switched and glad I did. More info: after update to lollipop now it is very glitchy, I have to restart my phone every morning after it's been sleeping because once an app is opened I can't close it. Still like it, just not as much

Almost perfect Great design and simple to use. Would love a background auto optimize option to deal with auto restarting apps while device is locked.

Love this... Best in category. Intuitive, effective, cool looking. Triple threat !

The only battery app that works, but buggy as heck This is the only battery app I've tried that consistently gets my battery to stop draining wildly, but it wreaks havoc with my lock screen and app switching. It automatically bypasses my lock screen and password, making my phone unsecured, and half the time when I try to switch apps it goes to a black screen. I have to lock and unlock the phone several times before it will let me switch apps or go to my home screen at all when this happens.

Nice app, great shortcut in the menu bar If this had a "begin on phone startup" feature it would be 5* Update- this messes with my automatic screen lock and overrides the pattern unlock. Sadly I have to delete it :( The shortcut menu is really great and I will really miss it

Does NOT WORK AT ALL ON One Plus Onr.Despite Giving So Much Feedback No Improvement And Also While Using Mobile Data Or Wifi.Would Be Appreciated.This Is THE NEED OF THE HOUR.

Good app. My battery management consultant

Sharon Miller at April 21, 2015

I'm giving because I don't understand it so it could be good or bad but I have to find one I can understand . God bless you

Junnyl Ferrer at May 11, 2015

Good, But when I open an app the power saver unfortunately desappeared. Please fix it, thank you and maybe next time I could give you a 5 star.

Naveen S at May 3, 2015

Love it! Works pretty good almost for all phones but needs some bugs to be cleared. All the best, job well done.

Battery saver Rxeapplication this is the best ofall match to this app.

Mitch Coe at April 21, 2015

Excellent! Several alternatives are themselves battery hogs. Not so with this.

Reliable and stable Does what it is supposed to do without gobling up to much resources.

Rating Excellent battery saver. I experience good battery life after installing this battery saver

Hugo Hernandez at May 2, 2015

I would like even more if whenever I plug in my charger, it didn't take me to the app

Aldi AJ at May 7, 2015
