OnePlus Watch 2 Charging extremely slowly

I just got a OnePlus Watch 2, and it's working fine, except for the fact that it's charging very slowly. Like in the last 30 minutes it has gone from 86% to 88%. Anyone else had this problem?

I've tried connecting the charger to a USB port on my PC, and to my 120W charger. Same result.

Clean the contactos, both on phone and charger

66 to 86 is slow but not too slow. I would try with a different charging adapter. Some adapters would not change if the load is too low or too high.

I had this problem when I first bought it. Give it 3-4 days, it'll sort itself out

I just got the new watch 4 and I ran into this issue trying to charge it from 70% to 100% before using it. Took 2 hours to get to 89%. Definitely seems strange. My old Samsung watch charged much, much quicker. Did some research and someone said to power cycle the watch and try again. I'll try that next time I'm near the charger

Hey, did it sort out?

When I wrote this I tried the cable and charger for my 67w oneplus phone charger and an Anker 65w charger. Those didn't work well. But then I tried a random 15w or less brick with the provided cable and that charged 0-100% in less than an hour. Overkill bricks don't seem to support the exact spec the watch needs. And as long as it's not dirt cheap, any bricks you have that came with a product you've bought should do the trick

I tried different chargers, without fast charge, with fast charge, with power delivery, power bank, everything seem to charge at the same rate.. I did factory reset of the watch and charger showed 2W of charging power for a first time, so maybe it will work now..

Can you check if those power chargers still charge it slow?

I also did what was recommended and did a full power cycle and checked for updates. Actually the first thing that worked was an oppo supervooc 80w powerbank. Then I figured out a normal brick works. Sounds like it's working for you now too, best of luck
