Hi

Since Windows 10 1809+, Windows has decided to remove this setting in the power mode of a laptop.
We have to turn down the brightness manually on battery, which is stupid. :unsure:

On Windows 11, has anyone found a way to automatically lower the screen brightness when it's on battery?

Thanks.

Thanks,

I tried your batch script, but unfortunately the screen brightness stays at the same level when I unplug.

I believe you have an integrated Intel UHD card on your system.
Please look under Intel.

In settings I turn on battery saver at 100% (always) with 'Lower screen brightness when using battery saver' turned on.
