Battery Widget is a free utility and tool app developed by unoshin for the Android platform. The app is designed to display battery information on the home screen, including the current battery percentage, discharge rate, estimated usage time, charging rate, and estimated time to full charge. This information allows users to determine the current battery status, how long the battery will last, and how long it will take to fully charge.

The app is also helpful for comparing charging rates between different chargers and determining which charger is faster. Battery Widget is easy to use, and users can add multiple widgets to their home screen. The app does not run as a service and does not consume a lot of memory. It automatically refreshes every two minutes, but users can change the refresh rate in the settings.

In addition, the app provides information on the remaining time for charging and discharging rates. The app records data from the last two charging cycles to calculate the remaining time. Users can also check the recording data and reset the recording rate in the settings.

Overall, Battery Widget is a useful and practical app for Android users who want to monitor their battery status easily and accurately.
