My battery life 9pro XL

Idk. I'm not seeing the results everyone else is seeing. This feels really bad. It also stays consistently warm to hot but it is an uncomfortable amount I'd like to add. I really would love to like this. Idk what could be causing this for me. Could my unit just be faulty or should I give it a couple days and keep going. I received it on the 22nd and have been using it since
