That's not the same as powering your phone off once a day or so for 30 seconds or more.
Uhhhhh, yes it is from an OS perspective.
From Motorola ->
"Your phone has capabilities that make it almost as powerful as a computer, so like a computer, for optimal performance, give it a fresh start by rebooting it once a day. Turn it off for one minute, then restart it. Rebooting refreshes your phone software and your connection to the nearest cell tower. It can also help extend your battery life."
It's Linux under the Android interface.
Rebooting a Linux box is equivalent to Powering it off, then on.
On a Linux machine "shutdown -r" causes the machine to shutdown, then boot normally.
Been doing Unix,Linux, Windows and Mac's for more than 20 years.
Waiting a minute removes you from the network and causes the phone to reinitialize with the network.
That is a network issue. Toggling Airplane Mode for a minute will do that.
So if stability with the OS is the goal, a simple reboot is all that is required.
If you are worried about network, leave it off for a minute.
If you want to force reinitialization with the network, go to Airplane more for a minute then switch back to normal.
