My watch broke because I charged following the manual

TLDR: My watched stopped working and Garmin assistance in Brazil asked for more than 500 dollars to fix it. What caused the problem? Charging exactly like the manual suggests. According to them, I should only charge it plugged to the computer.  So losing a watch because I followed their instructions is too much for me. Time to give another brand a shot.



I had already posted here (and elsewhere) about my heart rate monitor and other features randomly stopping. Tried a bunch of suggestions floating around, nothing worked.

Also noticed it would glitch out whenever the temperature went up just a bit.

Sent it to Garmin’s official support in Brazil (Proparts) and they said it had an overheating issue. The fix? Over $500. Oh, and they’d throw in a “bonus” 3-month warranty.

I told them I didn’t feel safe spending that much if it could break again in 4 months. So I asked what exactly caused the overheating.

They asked how I was charging it. I said: sometimes on the computer, sometimes using a wall plug. Then they hit me with this: “That’s the issue. You’re only supposed to charge it on a computer. Wall charging can cause overheating.”

Except… the manual doesn’t say anything about that. Nothing.

In fact, there are posts out there saying high-amp wall plugs are fine — the watch will only pull what it needs.

So yeah… my watch died because I did exactly what the manual says is okay.

Add that to all the other issues, and I think it’s time to give another brand a shot.

Goodbye Garmin.

  • You should escalate the issue with Garmin, that doesn't sound like a professional response.

  • (Of course that depends also on what kind of charger you used to charge the watch. Cheap rubbish from Temu or a charger from a reputable brand.)

  • A wall charger from a trusted brand should not cause any harm to your watch.

    As you might know, ProParts is a third-party company that partnered with Garmin to provide logistics in Brasil.

    If you did not buy your watch from the list of authorized vendors, they'll try to charge you if you have any problems.

    You must contact Garmin International. Although they aren't responsible for product support in Brasil, they are usually very helpful in addressing customer satisfaction issues related to ProParts operations.

    There was a toll-free number that I used to call in this kind of situation.

    Google says the number is 0800 047 5016, but I moved from Brasil a while ago, so I'm not sure this number is still working.
