Noticed that this is a setting disabled by default, so even though I disagree, it's intentional. It seems there is a bug after all. The bug seems to be that the brightness only changes when the charger gets connected. Which means that if your home's electricity is low due to storms, then the notebook goes to low battery, the brightness doesn't go back to normal because the charger was always connected. I've unplugged and plugged the charger again and the brightness returned. The change to "With energy adapter" setting should happen when the battery is receiving sufficient electricity. Seems like the computer has to shutdown due to low battery while the charger is connected but giving insufficient energy for this issue to happen after properly charging.

Issue on Plasma 6.3.1
It's very easy to reproduce this issue by having 10% or less battery, suspending the system, plugging the charger, then logging back in. The brightness should be low even when charging the battery. Still happens. The system suspended when going down to 5%, I plugged the energy cable, logged into my account, but the brightness is the same. I assume that the command to increase the brightness is not received when the system is automatically suspended due to low battery levels.
