Bluetooth doesn't stay connected

If I’m listening to audio over this device it works fine. The problem is that I want to keep my phone in another room when I go to bed. I bought this for the purpose of taking calls if they come in while avoiding the temptation to play around with my phone. If I connect the device and leave it alone eventually it disconnects by itself. Is there some way to prevent this?
