Battery One - Battery Health is a free utility app for mobile by developer Eco Studio. It is a battery monitoring and diagnostic tool that helps users check the health of their battery. It also provides more information about usage statistics and other details like charging rates for insight into how they use their devices.

Battery monitoring

Battery One - Battery Health is essentially a tool to give more information about your battery usage habits and how it affects battery life. The home screen shows various hardware stats, including temperature, total capacity, and charging rates while plugged in. Head over to the App Battery Usage section to see which apps use the most battery daily and up to seven days.

Other handy options include displaying battery percentages on or off the charger, as well as enabling a fully charged battery notification. All that said, most devices nowadays come with their own implementation of battery diagnostics from their respective manufacturers, which basically renders this app a bit redundant and unnecessary for most users.

Handy and informative

All in all, Battery One - Battery Health is a handy app that is a must-have to help you understand your usage habits and how they affect battery life. It's easy to use and is quite informative without being overwhelming. However, most mobile devices now have their own built-in implementations. If that is not the case for you, give this one a try.
