besides of those that you mentioned, you need to check all the apps installed in your phone too

That's odd. I got my phone almost 2 weeks ago and battery performance has been solid. Standby overnight with location on, wifi all night, I lost about 1% every 2 hours.

Any apps that crashed frequently or unusual pattern of battery utilization for those apps?

Your SOT seems kinda low with 35% juice left assuming you started with a full charge. On average, I am getting 5 hours of SOT with my Note.

I don't use Samsung Dex, so I won't know if it's consumption figures are normal but it seems to utilize quite a bit. Other apps appears to be normal.

Yes I think he installed Dex by accident. Should just uninstall it since he isn't using it. Battery performance should improve.

Just the usual apps. Facebook, ig, twitter, whatsapp, those Google apps, waze. I switch on traffic information notification to work from Google in the morning.  I disabled the Microsoft apps and put most of the apps that I don't need notifications or running in the always sleep setting.

My battery has been like that out of the box. If there's improvement it's minor cause I don't notice it. I always have around 96% battery when I wake up. So far I only need to charge during the day on the 1st day cause I was setting it up and playing with it. Other days it can last well into night with average 5 hours sot. But it can get slightly less when I'm on data most of the days.

Did you install Samsung dex by accident? It uses quite a lot of battery. I don't have it preinstalled.

Edit : btw i don't use always on display. I use led indicator instead.
