MacBook Air M5 battery draining too fast

My Macbook air M5 battery is draing too fast. It went from 80% (I charge it up to 80 max) to 50% in about 2 hours of medium use like 4 tabs on safari and vscode. At that point I checked activity monitor and it was showing only 2 hours remaining on 45% charge!!

Macbook is not even 2 months old.
