Performance Issues

Hello Mojang,

I'm having performance issues with my Minecraft game. When I play the game, the FPS goes to 29-30 FPS. This PC that I'm playing on is a HP Pavilion Gaming 15 Laptop. When it is plugged in, the FPS improves, but when it is not plugged in, it locks at 29-30 FPS. Can you guys see what is the issue? Thanks.

Sincerely,
