Why is my Note9's battery life draining faster?

[Android Central Question]

I only got the phone for 3 days now, first days didn't drain like this...checked battery in device maintenance and it seems 'screen' is eating up 11% of battery...the rest is at 0% or 1%. 2 hours and 20 minutes ago it was fully charged now it's 80%.

That seems okay to me but I'll move the thread to the Note 9 forum if you wish.
