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.

The only action to solve my issue was to restore power plan settings to default (control panel -> power options -> edit plan settings -> restore default setting for this plan.
Before i have tried many other suggestions but no one was working for me.

Mikhail 1 Reputation point2022-02-05T21:11:18.427+00:00 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?
