How Does the Battery Information Tool Work?
- The tool uses the Battery Status API to read your device's battery information.
- It displays charge level, charging state, and estimated time remaining.
- The display updates in real time as your battery charges or discharges.
- All information comes directly from your operating system through the browser.
Frequently Asked Questions
- Why doesn't the battery tool work in my browser?
- The Battery Status API is only supported in Chromium-based browsers (Chrome, Edge, Opera) on desktop. Firefox removed support, and Safari has never supported it due to privacy concerns about battery-based fingerprinting.
- How accurate is the battery percentage?
- The percentage shown comes directly from your operating system's battery driver. It is as accurate as what your OS reports, though actual remaining time can vary based on workload.
- Can this tool check battery health?
- No. The Browser Battery API only provides current charge level, charging state, and time estimates. Battery health diagnostics (cycle count, wear level) require native system tools.
