Such a amazing app.I was searching a battery saver app all over the playstore but couldn't find like this one.l had downloaded many apps but they didn't worked. And today I got this. I can't believe even you can't believe that because of this app only 44 percent charge was sucked in 1hr 46min. I can't believe thisss. Thanks for this app.

The only function it does is limit internet usage. That doesn't seem to work either. (Hello Sam, my battery was down to 8%. My day setting was set to 20%. As it read, the internet usage should have been suspended, but it wasn't. If I launched a local news app, it updated with the current news normally. I can't send you a log, I have deinstalled the app)

Bought a paid version.Not satisfied with the service. Highly fluctuating .Sometimes 1%battery drops in 9 minutes and at times in 4 minutes.Now at 11 pm ist 76% to 75% dropped in 5 minutes, and 75% to 74% dropped in 8 minutes ,again 74 to 73 in only 3 minutes.Seems money wasted.

Works beautifully. I am seeing bettery life of almost 3 days on single 100% charge. Bought pro version and set 20 min interval on day mode and 45 min interval on night mode. Everyone should have it. My battery is 3060 mah and goes 3 days on it. Imagine life on 4000 mah and bigger batteries. Must hit 5 days probably. Its my must have app now along with lmt launcher 3.1.I suggest a little bit of visual beautification of ui and more advertising.

This is a good app it will save your phone's battery. But this app will disconnect your internet whenever, the screen is off. But I disallowed that option and Iam getting messages and notification very late.
