I’m mostly playing BG3 those days and the battery lasts max 1,5-2 hours until I have to plug it again. So if I have a long playing session (like today, slow Sunday) I will have to charge it pretty frequently. Is it bad for the battery? I wish it lasted longer, but oh well (don’t see myself upgrading to oled at this time).
The device is meant to be used and abused. Play and charge on it as you want without regard to how often you do it. The battery replacement you might need years down the road is probably about $20 bucks.
