Battery test

Battery Diagnostics

Read real battery information from your browser. Values come straight from the Battery Status API — nothing is estimated.

Battery test not supported here

This browser does not expose the Battery Status API (navigator.getBattery). Many modern browsers have removed or never implemented it for privacy reasons. No battery values were estimated — we never fabricate device information.
