You can also generate a Battery Health or Energy Report with Power Efficiency Diagnostic Report Tool.

7] Calibrate your Laptop battery

This is one of the best options if the battery suddenly drops to 0%. Windows only estimates the battery remaining time depending on the laptop usage and assumes you will continue using it the same way. As the laptop usage changes, the estimation changes accordingly. Though this estimation is nearly accurate, if you see a sudden drop in the battery remaining time and percentage while using the laptop, then you can calibrate the laptop battery manually.

8] Update the BIOS

We also suggest you check for BIOS updates. Before updating the BIOS, you need to check the version of BIOS from the System Information or Command Prompt. If an update is available, install it. You can download the latest BIOS update from the official website of your computer manufacturer.

9] Your battery might be faulty

If none of the solutions work for you, then there is a possibility that your battery is faulty. In this case, we suggest you replace your battery. Before any repairs or replacements, ensure your important files are backed up to avoid data loss. Get professional help to confirm whether your battery is faulty or not.
