Since it is a non replaceable battery is there a way to do a Real Battery Pull? Holding volume up and power for 5 secs will reboot. What I need is switch off and battery out, not start. I should be able to start later. In my old Samsung note 3 if I Physically removed battery and Waited for a minute, sometimes pressing power button for few seconds, would do wonders. It would remove any charge etc. Is that possible, or no need in this generation phone?
