Currently no issue is known with the Blue tooth model. When the first batch of MK Mac keyboards came out we had a 10 min of inactivity shut off time. We and users quickly realized that this was not enough time and set the keyboard to 30 minutes of inactivity. Meaning if you are not using the keyboard for 30 minutes the keyboard will shut itself off to save battery. Once you touch any key the keyboard will turn itself back on and reconnect automatically.
