Ideally, you should turn your device off or put it in Airplane Mode before placing it inside the Faraday pocket (VELCRO® pocket) of the ConcealShield®. While your device is inside this pocket, it will constantly search for a connection to a cell tower and this may drain the battery.

We do not recommend leaving your device in the ConcealShield® overnight, or longer than a few hours without turning it off or putting it in Airplane Mode first.
