Note 10 plus warming up/heating up

That seems normal, assuming you mean the phone is still powered on. That means the phone would still have a standby time of >10 days, which is impressive.

Yeah it is still on, but I am just baffled to what could be the cause of the drain when everything is off including the cellular tower connection
 
There are still processes that run -- as far as I know, there's no way to completely freeze all system processes (and if there were, you might as well just power the phone down).
 
Around 15 days

What the heck hahaha. So its like you turned the phone off with 100% of battery for 15 days. When you turn it back on the battery is 98%?thats very normal hahahaha. So per month its 4%.

You could actually turn your phone off for a year and have 52% of battery left!!! Hahahaha.

Lol yea, actually 81 percent and then I find it 79
 
I managed to overheat mine the other day while down in Kona for a gymnastics meet. I was recording the routines of everybody on the team and eventually, my phone told me to stop because it was overheating.
 
That's very strange. I wonder what's causing that. Prior to purchasing my Note 10+, I saw some notable tech reviewers saying their units were running very warm.
