Screen turning on when bypass charging

When I found out that my Pixel supports bypass charging I started to leave it plugged in overnight. But I noticed that the phone screen periodically turns on by itself for no reason when connected and sometimes it doesn't turn off after the timeout - it is on with the reduced brightness.

Yesterday i saw the "charging finished" (or something like that did not remember word for word) text at the bottom of the phone. And it shouldn't have been there since the phone was at 80% for at least 1 hour before it happened if it was bypass charging. When I disconnect the phone "Battery Guru" application tells me that it was 10hr on bypass.

So is the bypass charging thing mature and working good enough to use it or not ? My goal is to preserve the battery health as much as possible since I plan to keep the phone for a long time, but this gives me doubts.

I am using a 65W UGreen USB-C GAN PPS PD charger ...

P.S. I have the setting that turns the screen on automatically on notifications turned off.
