Razer Blade 15 FPS Issue + Razer Insider Peripherals

Hi, I have a Razer Blade 15 with the 2080 Max-Q and it was fine for the first 1-2 months however now it stays on 50-70 FPS on CS:GO and other games etc when it is off charge and when it is plugged in it goes to 150+ FPS as it should. Im not sure what the issue is.

Also anyone know how to let Razer Insider know what peripherals you have? I have a razer mouse, headset, laptop, mousemat and headset stand but im not sure how to let insider know to get the rewards.
