技术说明
The Battery Status API exposes level and charging state in browsers that still implement it. It provides an estimate, not a measurement of capacity or health. Many browsers have removed or restricted the API for privacy reasons.
A battery level that drops quickly may reflect workload, temperature, or calibration. This page cannot read cycle count, design capacity, or manufacturer health data.
故障排除
Battery information is unavailable
Your browser may not support the API. This is a browser limitation, not necessarily a battery fault.
Level does not change
Level is reported in coarse steps and may update slowly. Use the timed observation over a longer period.
Values differ from system settings
Browser reporting and operating-system estimates can differ.
Export does nothing
Allow downloads for this site and try a different browser if the Blob download is blocked.
