[Q] Magnet keeps activating screen, drains battery topic

I found out that whenever a magnet is close to the screen (like the ones to be found in auto wake/sleep smart covers ) the screen will go off, as it should, but wakes up again after 10 seconds.
It will keep doing that forever: wake up, sleep due to inactivity, wake up, sleep, etc etc. It is obvious that the magnet is somehow triggering the screen to wake up.
You can easily reproduce this by placing a white board magnet on the device (place it between the hours and minutes of the lockscreen clock). Just wait and see what happens.

This means that you are certain to drain your battery when your phone is idle, sitting in a smart cover like the official one from Casemate.

I would love to use the smart wake, it worked flawlessly on the Nexus 5 but works only as a battery drainer on the N6
Is there anything that can be done about it? or is it a hardware issue?
