Bangle JS2 purchased Aug 23 2023 no longer charging

If I plug in the cable, I can measure 5 volts on the pins. Every once in a while, It will boot when I plug it in, but it doesn't charge... battery indicator stays at 1 or 2 percent.

Sorry to hear it's stopped charging... What do the contacts on the back of the watch look like? Are they still shiny?

What I've seen can happen is the protective tape comes off the middle two contacts, and that causes all the contacts to corrode (electrolytic corrosion), and then it'll struggle to charge.

If that's the case, I'd suggest using some mild abrasive - not sandpaper, but maybe just rub toothpaste over the contacts for a while with a cotton wool bud or old toothbrush. Then hopefully it'll start working again, and you can re-cover the middle 2 contacts to stop it corroding again.
