I suspect some (not enshitified) devices even designed around it because I remember it killing devices back in the day but the more recent times I've had it happen, like with a wireless guitar controller, the device was fine, just a bit crusty in the battery area. Though if you've ever opened up a guitar controller, they are mostly empty space, so it might just be the nature of their use case vs something like a gameboy, where everything is packed in as much as the thermal situation allowed.
