How did you get 13 hours ,that's impressive
I noticed one thing, if I use the screen on more, youtube, video, telegram and others, it reduced my time of inactivity and vice versa. I am currently like this in the picture. By default, I am 24 hours with the screen inactive and about 6 to 8 hours with the screen on.By default, the phone is on 5G network, WiFi is on, screen FHD+ and 120Hz, battery is on Light mode, screen on automatic mode. Most applications are in Deep Sleep, the rest are in Sleep and none are awake.
I don't know what else to write, this set on youtube that I made is at 60-70% of the screen, I watched clips in the channels I have a subscription to and then I had a big problem with vanced, namely that constantly when pausing or turning off the screen it was throwing out the profile and what I was looking at. It took me a week to find out that the problem was in Vanced Micro G and deleting and a new clean installation fixed this problem.
