I don't believe there is another way of doing other than the power button, sorry.
But I think to increase the screen viewing time you'd just have to adjust how long before the device sleeps. Do that by:
Pull down the notifications bar and select the setting icon > select Display > select Sleep > change to a maximum of 10 minutes.
You can also make it so that it never sleeps while on the charger:
Settings > Developer Options > check Stay Awake
