My Fitbit charge 5 also went black yesterday. It has been charging over 24 hours now—and nothing. The charge went from 17% to 0 in less than an hour yesterday afternoon which was also not usual for it. This is a device I used for 10 months. I’ve tried every suggestion on the forum, cleaning Fitbit and charger, using another outlet; I’m quite sure it’s past its warranty as I wore my Charge 2 most of the last year—it was super dependable even after I somehow cracked the face almost in half, which was the main reason for the Charge 5 purchase. I will not be purchasing another Fitbit, the complete lack of customer support from this company on its products is beyond frustrating
