My MacBook Air M1 (2020) drains the battery faster than expected when I keep my Android phone connected to it

The battery drains very quickly on my MacBook Air M1 (2020) when I keep an Android phone connected to it. I use it for app development. Is there any way I could stop the Android device from charging? If not, would it affect my battery’s lifespan if I plug my MacBook to power always while the Android phone is connected?
