Bluetooth disconnects devices regularly

[Daniel Holm]

My mouse suddenly disconnects randomly, while I am using it. Works fine for a while, suddenly it seems to disconnects because I can't use it, and then I press all the buttons, restart the mouse, or forces the Bluetooth to connect using the Bluetooth indicator again, and suddenly it works again.

Same thing goes for other Bluetooth devices. Using my Nexus 4 as a Bluetooth modem it's the same.
