Howdy, Paul, I keep my unit in its case. Yes, there's heat, especially when the battery is perhaps 50 per cent or less. This is reasonable because we have a fast-charging system and a battery designed to handle this. Also, the charger has enough reserve to charge the unit even when it's running with the wireless on. Maybe someone will have a different thought, but I'm not worried about this at all! Joe G.
