Remember, this isn’t an app, but a widget: you can only access it by placing a widget on your homescreen. You’ll notice that there’s only one widget (we’re missing different size widgets, only available in the full version) which is a battery level indicator. However, the widget isn’t the most important point of this app, but its battery tracker.

Once the widget is placed on your homescreen tap it. You’ll get to Battery Monitor Widget dashboard. From there you can useful info concerning your battery usage. From home, you can see phone status (charging, discharging), battery health, technology (mAh), battery level and empty estimation time. The latter is also displayed on a graph below.
From bottom tabs you can access battery usage history, battery life estimation in different scenarios and, finally, a battery calibration tool. In addition, there’s a shortcut to Android built-in battery testing and usage menu. Developers let users know that mA estimation isn’t accurate in all devices (more information on their website).
Battery Monitor Widget is a great tool for those who like to change ROM and compare their performance.
