My laptop runs Windows 11 very smoothly and fast when plugged in, but it slows down a lot when working on battery. Animations are delayed and files open very slowly.

    Try to run Power troubleshooter from Settings app > System > Troubleshoot > Other troubleshooters. Let us know what it reports back.

    Hi! I have similar problem. My laptop runs under intel i7-7500u very smooth from power source. When it switches to battery, the CPU frequency freezes at 400MHz. I tried both Optimal and Maximum Performance profiles but it didn't help. Power troubleshooter didn't find any problem. Any other ways to fix it?

    The Intel I7-7500u isn't listed as a supported Intel CPU for Windows11: https://learn.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-intel-processors
