Battery Question

hi i received my first gaming laptop yesterday & everything js running amazing. it’s very smooth when plugged in & also at a high battery percentage.

however, i’ve noticed that once it gets to about 30% and lower my game starts experiencing some lag in game. should i be concerned? i don’t know much about gaming laptops - all runs well but it’s just this minor issue.

nevertheless, is there any recommendation on how long i should allow my computer to rest? it seems like i’ve been on all day straight since yesterday lol.

thanks in advance for anyone who will answer
