how do I turn off my phone with a broken lock button and screen doesn't work?

my lock button broke a few months ago and I've been getting along fine without it due to assistive touch. Now, my screen won't work at all.. I can't slide it to open it, can't slide to power off .. only thing I can do is slide down the today thing at the top and slide it back up .. I can get siri to bring me to my password screen but I can't type it in .. any ideas on how to turn off or restart my phone seeing as I can't slide to power off? This happened over night so my phone is at 94% as of right now and I don't want to wait for it to die because that will take forever .. 😟
