Voltie

Voltie is a compact battery and performance monitoring app for Android that provides clear battery status, usage history and simple tips to extend runtime. It displays real-time charge level, estimated time remaining and sends optional notification alerts through a lightweight interface designed to run with minimal overhead.

Key features

Voltie's real-time monitoring shows current battery level, temperature and charging status. Usage history lets you review recent discharge and charging patterns to identify high-consumption apps. Smart suggestions offer non-intrusive tips to reduce power drain and improve battery life. Custom notifications are available for full charge, low battery or unusual battery behavior, and they can be enabled or disabled as you prefer. The app remains lightweight so it does not add significant overhead.

Privacy and permissions

Voltie requests only the necessary system permissions to read battery and usage information and does not collect personal data. All information is stored locally unless you choose to export logs for troubleshooting.
