Note 5 drain

Guys
I'm having low screen on time on my note 5.
I used it for 2 hours and 45 minutes and it went fromantic 100% to 15%.
Someone please help.

Re: Note 5 drain

What app(s) did you have open and active during that time? How was the cell signal? What does the Settings\Battery show for the apps or cell usage?
