Screen Dimming Became Too Dark After Battery Optimization

[anon(10300249)]

Hello,

I have Redmi S2 with MIUI 11.0.5 & Android 9. Everything was fine, but yesterday I decided to use battery optimization (the one that comes with MIUI). It changed few things like screen sleep time and etc. Later, I reverted things back, put my screen sleep time back to 1 minute of inactivity, however, I noticed that screen dimming is too dark. The time before screen goes off completely it, phone dims the screen like it should, but after this battery optimization it's much darker. I tried to find where to change it back how it was, but couldn't find it. Can anyone help me, please?

Ignore my post, I think I had 2 minutes inactivity earlier instead of 1 minute and that's why it felt different.
