I see we've posted similar and thanks for commenting on mine. I see yours disconnects for about 5 seconds. Mine turns off completely as if the battery is dead but it's not. Has plenty of charge, at...

I've turned off the power saving mode to see if the had any effect - none. Has to be a design/manufacturing fault of the device.

Issue: after approx 25mins the device switches itself off Battery: fully charged Resolution: power back up. works again for approx. 25mins then switches itself off again. Is this a device fault?
