Ratings and reviews

The app is good, but not very powerful. You need to pay before you can use the battery percentage widget and charging graph, which are free in some other apps. Plus there are ads! Apart from all that, it is minimalist and easy to use.

Broken by Android 15! I was very happy with the app until a my phone got an OS update (nearly a year old!) Now it often stops recording usage/charging, records sometimes stop midway through a (dis)charge session and have v long gaps. But previously it was a 5 star app. Graphs & detailed usage data is interesting and now includes %Screen On. Warnings for overheating, low & fully charged battery have become vital and I can set the same levels. No other free app I've seen has these features.

very good app. I've been using it for a few months. initially installed for checking battery health, but now using it to see charging speed. back then it used to consume so much battery, now it is less, but please reduce the consumption further, If possible. edit: I kind of feel the battery kind of charges faster when this app is on background (like consuming power from charging, or restricting power or something like that), I need to check it
