I'm not sure if anybody else is having this problem.

But I picked up the ultra 2 and the new 9 for my wife and I. With the new watches all of our multi-device throw an error now when trying to charge the watch.

Watch 9

This charger was able to charge my ultra fine.

Ulta

Ultra 2

So it appears like Samsung changed the charging on these watches making a lot of multi-device chargers useless with these watches.

Anyone have a nice multi-device chargers that's working to recommend?

Hi Britewood 🙂
Congrats on your new devices! I hope besides the charging issue you and your wife have been able to enjoy them. What brand are the multi device charges being used? I personally use the trio pad from samsung as well as the chargers included with the watches. This is my 3rd gen of the watches from the 7, 8 and now the 9 and I've had zero compatibility issues with phones, buds or watches.

From what ive seen reported the charging pucks for the Watch 9 and Ultra 2 models differ from those of previous iterations, necessitating the use of the new pucks for charging these devices.

I just charged my Watch Ultra 2 with the same puck that came with my 8 Classic.

I've had zero compatibility issues with the pervious 2 pucks from the watch 7 and 8 for my watch 9. I have seen some compatibility issues due to using the wrong brick though.

What’s a compatible charging stations for Galaxy watch 9? Noticed that a 45W is needed for fast charging. I have been unable to find one that states support for Galaxy 9. Any suggestions

Thats good news that they're happily taking that one back. And thats one thing I've loved about the watches is the brand new puck that comes with them every year. I hope that included perk never goes away. Glad to hear you're still using your trio pad as well. That has to be one of my favorite chargers of all time. I got mine on a killer deal on Samsungs Amazon store so I'd be super sad if it was no longer able to be used as well. Hopefully the future holds more charging options that don't break the bank. But if you find one that work absolutely feel free to drop it and show us what you got. Good luck on that search 🫡

Could it be because of change from the xenous chip to the Qualcomm chips?

Thats a really solid question! However the chip (exynos vs snapdragon) doesn't control wireless charging compatibility. Charging speeds and charger compatibility are governed by the WPC/Qi charging coils, power management and wireless charging receiver setup thats built into the back housing of the watch. Third party multi chargers fail mostly due to coil size mismatch, physical clearance or lacking Samsungs fast charging negotiation protocols meaning it cant cleanly hand shake with the charger.

A little research online shows that the watch 9 is having charging issues, non compatibility with all previous galaxy watch chargers, and overheating while charging, causing a throttle issue and reducing charging speeds. I'm not sure why Samsung isn't just addressing this, they're going to have a lot of return for defective engineering if this isn't something they can fix with a very quick update before return windows close. Noone should have to modify their watch band, or stick to a puck charger, or buy all new (not even available) trio chargers, or put their charger or watch on ice, or put on a fan. This is actually ridiculous for a flagship expensive product.

Understood and I completely hear your frustration loud and clear. As someone who's been actively putting the watch 9 through its paces since August 5th, I have been seeing all the chatter as well as doing direct controlled testing.
If your watch 9 as well as others is genuinely taking 4 hours on the OEM puck theirs a few things that could be the culprit.
If the OEM puck is plugged into an ancient 5w usb-a hub and or low spec power strip this can cause issues. Or this could be a legitimately defective unit that needs a warranty swap not a global "defective engineering design flaw".
A 4 hr charge time is not the intended behavior. Under proper conditions with 25w samsung brick and the OEM puck, A full charge takes around 60‐80 minutes. If yours overheats and throttles on the bare OEM puck with an official Samsung brick, its highly advised to contact Samsung support for a warranty replacement, as that is a defect with your device, not the baseline standard of the entire hardware lineup.

That would make sense if it wasn't an issue being reported by tons of users, and if all the watch diagnostics didn't register as normal at the same time it still does this. If a watch is heating so much that it gets too hot to charge on the provided puck with the right current of power, thats a design flaw, not a device specific issue, and it wouldn't be so many people with the exact same problem.

Also , samsung support didn't help at all, just wants me to mail my watch in to see if it needs repair, which will come back saying it doesn't, and ill just be out my watch for weeks past my return window. A FEW defective devices would be a device issue, but this is being reported widespread, and the issue is easily goggleable that Samsung is failing to respond or do anything to fix it.
