So far, the best app for battery management and details are pretty accurate. The UI is very minimalistic and follows Android Material Design. 1 less star due to two things: 1. Every time we have to configure when the app is updated (not sure if it's some Android limitation). 2. The pricing point would be fine if it were a one-time payment instead of a subscription.

Hi, thanks for feedback, regarding app reconfiguration, it's necessary as we don't know what is changed with OS update. Regarding this we do checks, so app can continue working normally. Regarding payments, many countries already have reduced pricing, to suit wider audience, also 24h subscription is free and can be used unlimited times. 😊

This app saved me from having to reset my phone! My battery started to drain rapidly after I was on a video call with my brother about a month ago, and I have no idea why. I tried everything short of resetting my phone, which I was just getting ready to do. I found this app and decided to try it, and it immediately fixed the problem, and it's working as it had been before what ever caused the problem. Definitely recommend this app, and I'm extremely thankful I installed it, and that it worked!

Pretty good. Id buy the app in a heartbeat but it's ONLY a subscription. Nope, not happening. Might uninstall eventually, there's always a better alternative to a subscription model. Edit: US. It's the principal of the app being purchasable and it being a subscription, it could be $1 a year and I'd still not subscribe to it. Every little thing is going subscription and I will not do it. Neither should anyone else. 24hr ad is nice, but I won't ever subscribe to an app, it's entirely ridiculous

Thank you very much for your feedback. 😊 We highly value our users suggestions and ideas, and thats how the app is actually built. I'm sorry that you don't like the payment part for an ad removal and some extra functions, but I highly value my time involved into developing this application on a regular basis, and as well doing fast user support.😊
