About Battery Status

Diagnostics should run locally without installing extra utilities. Battery Status is built for that job: check battery level, charging state, and time remaining via the Battery Status API — private, in-browser.

What Battery Status checks

Check battery level, charging state, and time remaining via the Battery Status API — private, in-browser. Results describe this browser and device only — useful for isolating mute switches, permissions, and display quirks.

If the test fails

Check OS settings, tab mute, extensions, and whether another app has exclusive device access. Retry after a click if the browser blocked autoplay or permission prompts.

Where your data goes

Battery Status runs in your browser for this job. Your battery is not uploaded to FileToolsHub servers for the conversion itself, which matters when you are dealing with private notes, drafts, or local files.
