I have a Xiaomi Redmi note 7 device global version which features MIUI .

Now I see the MIUI update, I press the download button and it starts downloading, I then leave it to download during night.

When I wake up I see it as it didn't even move when I expect it to be finished, if I leave the screen on it seems to continue so probably a power saving feature.

I searched and searched, since my android version is 9 wi-fi sleep policy option disappeared and PieWifi app didn't work.

People also said something about restricting background data usage which I think I found under Security -> Restrict Wi-fi but I can't find the system updater app there.

I googled much and most options I see on internet I don't find on my phone.

So how to make download work even if screen turns off ?
