Ratings and reviews

It's a great app. I love that it tells you all the information you need to know about your battery. I've tried other apps and never cared for them. Their is a lot you can do without a subscription but one thing I hated is a manual data reset is locked behind a paywall. But if an app requires a subscription I love lifetime subscriptions. And this one has the option at a pretty cheap price. So thanks for that.

The best battery app (period). Most of the best features are available in the free version. It lets you put the battery temperature in the notification area with the lifetime version. you can also completely customize the UI. I love the battery graph over time as Android auto was making my phone run very hot. IT still does especially while charging so I moved it to a vent air conditioning holder. Problem solved for the summertime.

Very chaotic design. Minus sign everywhere while discharge session is annoying and absolutely unnecessary. I know without that in which direction the values run. On top of that, the handling of the plus/minus sign isn't consistent. For example, when I display the current value in the status bar, it is always positive. However, when I expand the view, the same value is negative. This bug has been around forever, and nobody seems to care.
