I replaced the battery on my Apple Watch following the instructions here: Apple Watch Series 1 Battery Replacement Everything went fine, but when charging it for the first time: I don’t get the changing snake symbolThe Apple logo will display for <1 sec and then stay off for about a minute. I don’t think I tore any of the cables or shorted anything. I am thinking it might be a defective battery. Has anyone had this issue and resolved it by replacing the battery with another new battery?
My best friend had this issue and sent his series 1 to me for a new battery. Although I’ve tried two new batteries from different suppliers, it still did the same thing. I’m wondering if the software got corrupted or something. I would maybe try another supplier for the battery. I recommend mobile sentrix.
