Why does my razer blade 15 run so much better when plugged in?

[coffin6610]

When the power is plugged in the laptop runs 90-130 FPS on fortnite but when it’s not plugged in the FPS seem to cap at 30 and I don’t know how to fix it

Have you gone into the setting and changed the windows power management plan?

It might be running in a different powerplan when you unplug the laptop. All laptops start running in lowest/conservative clock settings when power is not plugged in.

Its normal. Just change the power plan and set everything to maximum performance either in the OS 'power options' or in the software provided by OEM(if any).
