Is it bad if I charge my laptop and play at the same time?

I want to play Csgo and I want to know if it's bad if my laptop has 100% battery and I still leave it connected to the charging cable while playing games. Will my battery be destroyed?

In the long run yes. At least that's how I ruined my batteries. Just take the battery out. The device also works without a battery when the power cable is connected.

I can't take it out

Research results of the RWTH Aachen state that the batteries last the longest when they are always loaded between 30% and 70%.
