Xreal Air 2 Factory Reset

I've had the Air 2s about a year and half without too much issue, but recently started having this issue where the glasses will turn off after roughly 30-45 seconds connected to mobile device, and anywhere between 2-4 minutes connected to PC. Just varies. I've tried firmware updating with nebula app and via web browser, but no fix. Is their a way to factory reset the glasses to see if the issue is related to a recent firmware?
