How to Fix iPhone Vibrates for No Reason (See How Users Said)

by Jenefey Aaron   Updated on 2020-09-03 / Update for  Fix iPhone

This has been going on for a long time now (feels like maybe a year?) I have an IPhone 7 and it randomly vibrates as though I got a notification or plugged it in to charge, however, I didn't. Just a single vibration, not a double like a text.
It doesn't happen all that often, but usually once or twice a day, enough to be annoying and deceptive. It will happen both while my phone is asleep right next to me, and while I'm using it......
