Need to force restart my phone but my volume down button is broken. How do I do it?

[Windows Central Question]

I have a Nokia Lumia 720 with WP 8.1. My volume down button hasn't been working for a while. Now my phone is unresponsive and I don't know how to shut it down. Any advice? (I know I should get the button fixed.) Thanks in advance!

Hold power button for about 10 sec it will shut down the phone
