MacBook Pro 14 Battery

So m1 pro is experiencing Massive battery drain , bought like last month. It goes from 100-40 in like 1.5 hours. I tried updating and stuff couldn't get much.

I am thinking to visit the Apple store genius bar, need help. Will I be charged? Should I back-up? And I was thinking to Visit the Saket, Delhi one since it's the official one.

Appreciate the help
