Leaving game cartridges inside a Nintendo Switch, even when you're not playing, is fine. While Nintendo never addressed this specific question, gamers seem to agree there's no problem. The primary "trade-off" would be the mechanical part of the cartridge slot, as the spring mechanism inside the slot would be continuously compressed. Instead of worrying, spend your time discovering these six features you never knew your Nintendo Switch had. Additionally, the cartridges themselves are solid-state media with no moving parts, which makes them quite durable against everyday drops and minor impacts.
