I don't have much of a back story on it, a friend gave it to me and said it quit working one night. He didn't know if it updated before it quit. it was not boot looping before it quit.

Anybody got any ideas on what it might be?

Update:

I bought another Galaxy watch on eBay for parts to potentially put two together to make one good one. Unfortunately in the eBay listing it was labeled as boot looping but now that I have that it happened but it has not shown any life since I've had it, so back to square one... At least it was only $20 lol

I did take it apart as well just to check for water damage and it was spotless so more than like more than likely the same issue as my other one..... Nice

At first it worked fine: I charged it up, ran it down completely as instructed, and then went to charge it. The watch would charge for a few seconds or minutes, maybe showing 0% to 3%, then stop. If I tried again (and again) I'd get the same results.

Finally I gave up, assuming the battery was faulty, and put the old battery back in. It had about 14% power but immediately ran down to nothing and the watch shut down. It's refusing to charge again.

What am I missing? Could there be a bad connection to the battery somehow? Damage to some other part of the watch?

I want to change it and bought a new gasket of ebay.

Now my biggest issue is, that I don´t know how to attach and seal the new gasket. Even after some googling, searching youtube and even asking AI I haven´t found any usable instructions on that.

Could somebody please explain to me, how to attach and seal the new gasket?

I can provide photos if necessary.

Thank you in advance

With appreciation, Manfred

Here are links to the battery and guide I used.

The new battery seems to be lasting exactly as long as the old one: about 16 hours. I notice one of the reviewers on the store page had the same issue.

I followed the calibration instructions exactly, charging the watch fully and leaving it charging for two hours, running it down until it shut off due to low battery, and charging up again, so that's not the problem. Am I missing something else? Would a factory reset make a difference? Is Ifixit shipping sub-standard batteries?

What to do here . I tried the normal

Two button restart with and without the charger

Chose the classic one because in the selector i could not get a lte one as mine is

Doing the Two-Button Hold to try to reboot the watch doesn't do anything. I'm guessing the watch is completely drained, and will not charge up again for some reason. Anyone seen this before, with Galaxy Watch 4 Classics, or other Galaxy Watches, perhaps? I'd love to attempt a repair before giving up and buying a new watch to replace this one.

I replaced bezel ring and sealing for bezel with brand new parts in my GW4 classic 46mm, but still it doesn't.

When i teared down the watch i couldn't notice any dedicated sensor for this.

I hope that somebody could help me understand how it works.

So my idea was to put the inside of watch 4 put in to watch 3 but is that mechanically posible?
