Posted at 2021-12-16 by @gfwilliams Had you been able to charge it properly in the past? I'd say make sure you give the contacts a wipe with something to ensure they are clean. Also, just in case, put the Bangle in your pocket for a half hour or so before charging so the battery warms up. It may be you need to press the button to make it start up after you've charged it for a while. Posted at 2021-12-16 by user137752
Yes Contacts seem pretty clean, except the one that's a bit corroded. I was wearing the watch this morning, so it wasn't cold either, and my office is at 23°C; I don't think the temperature is an issue. How long should I press the button? I've tried holding it for 30+ seconds, to no avail. Watch has been plugged in for the last ~4 hours or so. Posted at 2021-12-17 by @gfwilliams Ok, that's an odd one. Just 1 second should do it, or if the watch had crashed, 10+ seconds would reboot it. However you say there's no voltage across the watch contacts? What about the middle two? That actually seems to be a good way of seeing if there's power on the watch - if there is no voltage there then the CPU isn't powered at all and it could be some kind of battery failure. Did you see the watch battery level getting low? I'm just wondering whether something other than the battery running flat caused the display to go blank... Had you got the Bangle quite wet at some point earlier? Posted at 2021-12-17 by user137752 Yeah, the battery was getting low over the last few days, I was planning on charging it yesterday. No voltage across the middle 2. I did take my shower with it, but it was far from the first time (did it almost every day for the past ~month since I got it), and the watch wasn't submerged. I searched the forum about that, and my watch seems to have the white membrane in the hole under the wrist strap. I really hope it's not water damage, any way I could try to rule that out? Posted at 2022-01-05 by @gfwilliams Sorry for the delay - honestly it's hard to know, but I'd find it hard to believe that a shower would cause it to get wet inside. If there's no voltage on the middle contacts then it sounds like a battery issue, since even if the Bangle CPU wasn't working you'd expect to see 3.3v there. If you haven't already, please could you try giving the contacts a wipe over with a cloth? It might be some of that corrosion is stopping it being powered properly - also just trying to get it properly warm (like 40°C or so) might make the battery more willing to take charge. You could also try a different USB charge just in case for some reason that wasn't supplying enough current. Posted at 2022-01-10 by user137752 Thanks for the tips, but none of them worked. I don't have a separate cable to test charging with, but as I mentioned in the first post, I looked at it with a multimeter and it seemed fine. I did try another USB power brick, and still no luck. Posted at 2022-01-10 by @gfwilliams Ok, thanks for trying to fix this. Looks like you might need a new Bangle then. I'll drop you an email. It may well be another week or two before I can send one out as I'm waiting for a new batch though. Posted at 2022-01-14 by kenp Hi, i am having the exact same issue. Doesn't seem to be charging. I am getting voltage through the wire but nothing on the watch. I am going to leave it on overnight. its been on the charger 3 hours already. i can give you my email if needed. Posted at 2022-01-14 by @gfwilliams Hi @kenp was your Bangle charging in the past, and now it's not? Or has it never charged properly? What do the contacts on the rear of the watch look like? Are they clean, or do they seem corroded slightly? Posted at 2022-01-14 by kenp No corrosion. Attachments: Posted at 2022-01-14 by johan_m_o As @gfwilliams said, did it charge previously and now stopped? Or has it never charged? Posted at 2022-01-14 by kenp
Attachments: Posted at 2022-01-14 by kenp ...also, it has charged twice since I received it. No problems then. I haven't actually worn it for more than a hour or 2 as I'd been trying to learn the IDE and how to code a watch face. Mostly its been sitting on my desk. Posted at 2022-01-14 by johan_m_o @kenp What's the result if you connect to the Web IDE while connected to the charger and enter Or is it completely dead? Posted at 2022-01-14 by diego Is it me, or is this pin slightly shorter? Maybe it's gripping? Attachments: Posted at 2022-01-14 by johan_m_o Good eye! Maybe it's not reaching the charging pad... Would definitely be causing problems. Let's hope it's that easy. Posted at 2022-01-14 by kenp I will check that and post a reply later today. Thanks Posted at 2022-01-21 by kenp Sorry for the time delay, Iwas on vacation for a week. Pin does seem to be not "springy" enough to come out as far as the others. Were these guaranteed for some amount of time? If so how do I get a replacement? Posted at 2022-01-24 by @gfwilliams @kenp yes, I am guaranteeing them. I'm finally expecting the new shipment of Bangles on Thursday so I'll get in touch soon after about getting a replacement out Posted at 2022-01-25 by kenp Thank you so much! Posted at 2022-05-05 by user143698 I'm having the same issue with mine. Charged fine the first couple of times but it's been connected for an hour now and no juice. Checked the contacts and everything is clean. Could it be a battery issue? Posted at 2022-05-06 by @gfwilliams Is the Bangle completely off now? Have you tried holding down the button for several seconds? There have been a few people recently complaining of issues, and it's just been because when the Bangle is flat and power is applied it no longer automatically boots. You need to hold the button down for get it to turn on. Posted at 2022-05-06 by user143698 Yes it's off now. I've tried holding the button for almost a minute and still no boot. Posted at 2022-05-09 by @gfwilliams It's possible... Do you have a volt meter? If you could check the outside connections on the cable to see if there's a voltage... How long have you had your Bangle? Sounds like not that long? Posted at 2022-05-10 by user143698 I don't have a volt meter unfortunately. I bought the watch in March and I was able to charge it at first. I then powered it off when not using it but since then I haven't got any charge. I've tried different power bricks but all the same. Posted at 2022-05-11 by @gfwilliams Ok, so basically you powered it off a while ago, and now it won't power back on at all? Or did you have it at a point where it was actually running, but not charging at all? I've just been trying with some devices here that got returned as having the same issue you have, and I've found it's possible to 'bootstrap' them. Please could you peel off the tape that's over the middle two contacts on the back of the Bangle? It's possible that just applying the charge cable with those contacts showing will be enough to bring the Bangle back to life (maybe try some different chargers now those contacts are uncovered), but if not please can you try this? https://www.youtube.com/watch?v=omIQ9mQTB7Q Sorry for the inconvenience. I'm still not sure what causes the issue, but if it can be solved at your end pretty quickly it'll save all the effort of having to sort out a return. Posted at 2022-05-17 by user143698 Still no luck. I tried with a 3 volt battery from a remote and it didn't boot it. Also tried charging with the tape removed and all pins exposed and with different chargers, but still nothing. Posted at 2022-05-18 by @gfwilliams Ok, I'll ask Christine if she can sort out a replacement for you. Posted at 2022-05-18 by user143698 Thanks, I appreciate the help and quick responses. Posted at 2022-09-10 by Rebeca Had the same issue, it was not charging. Posted at 2022-09-12 by @gfwilliams Great! Glad that fixed it for you! I'm still not 100% sure why this happens - I haven't had call to do it since making that video - but at least it works in some cases :) Posted at 2022-09-12 by Rebeca The watch turns on, but it's not charging anymore :( Posted at 2022-09-13 by @gfwilliams Argh, that's a shame. What do the contacts on the rear of the watch look like? Are they corroded? Have you tried using a different USB charger? Also, if you have a volt meter it'd be worth checking that there's voltage on the outer two contacts of the cable - it might be that the charge cable is broken? Posted at 2022-09-13 by Rebeca The contacts are not corroded, I already cleaned them. |

So my Bangle.js 2 ran out of battery this morning. No biggie, except now it doesn't seem like it wants to charge anymore.
I tested the contacts on the charge cable, and I see 5.25V across the 2 outer ones.
No voltage across any of the contacts behind the watch, and the third one (counting from the button side) is slightly corroded.
Watch has a black screen and is unresponsive when I press the button.
Any way I can force it to charge?
