How can I play Sims 4 without draining my battery rapidly? Battery health issue

@ggytygku I have a Nitro 5 laptop. I keep the battery charger plugged in when I play Sim 4 and it's never a problem. I did have a problem recently with my battery loosing power but very gradually over a two week period while it was plugged in, it went from 100 percent to 78. I was going to get another charger and then battery if I had to but just incase I moved where I had it plugged in and the battery was full again is minutes. The batteries these days seem to be very good for recharging and holding a charge.
