Hardware Playing while charging good/bad idea?

[Zeldalife89]

Ive always wondered because alot of times the battery runs out and i wanna keep playing but i dont i shut it off and charge it to full and start playing again...
but i was wondering if its bad for the battery to play while its charging?
Sometimes i just want to keep playing

in modern batteries, it shouldn't be a problem. unless the 3ds is wired to charge till its full, then let the battery take over till 95% before beginning to charge again like some laptop chargers do. that might whittle down on number of charges and such.

but really, I've been playing with and without charger a lot and my 4 year old 3ds xl battery still holds at least 90 minutes of charge. thats much better than my psp did

If something goes wrong you can buy a replacement battery.
