What is going on (Windows 11)

My Lenovo LOQ 16IRH8 battery suddenly started showing “less than 1 minute remaining” I think this happened after updating to Windows 11 25H2. Lenovo Vantage now shows a critical battery warning. (though the battery looks completely healthy and works just like before)

I generated a battery report and the numbers seem completely broken:

Design capacity: 60,000 mWh

Full charge capacity: only 540 mWh

What’s weird is that older entries in the report still show normal capacities like 36,000–41,000 mWh, then suddenly it drops to a few hundred mWh.

    Assuming that your physical battery is in normal state. I suggest re-installing the battery drivers software

    Open (Device Manager) --> Uninstall Them --> Restart your System

    Another Solution is do Full Battery Power Reset.

    1. Power Reset (Turn off your Laptop. then, press the power button for 30-60 seconds).
    2. Remove Battery if Possible (& Re-install it again).
    3. Discharge the battery fully from 100% to 0% (Then, charge it again)
