My macbook is not turn on without charger

Hello, I bought this macbook(m1) 1 month ago. Everything was working fine in first month. Then suddenly it behaves weirdly. My macbook only open when I plugged it with charger. And battery always show 1% charge all the time. It's really frustrating. I check the battery cycle. It says 5 which means battery is good. This is my first time experience with mac. And the experience is so bad. Can anybody here help me out?
