I needed this guide after my spouse put the carafe in the dishwasher and the handle sloshed no matter how much I shook it. It turns out water is easily trapped under the top cap; even though there's a drain hole into the handle, it doesn't seem to want to drain. I've wiped it off and left it to dry completely before reassembling it.

The contrast is poor here, but now that I have the cap off, I know that no spudger I have would fit there anyway. Instead I inserted a metal kebab skewer (shut up, I was in the kitchen ;) ) in the bottom of the handle, ring/handle first, and used that to push outwards/upwards on the top cap. That raised it up a bit and gave me a gap in which I could fit a spudger to pry it off.

Never mind, the watch made the same buzzing pattern when I left the battery out and connected the charging cable. It looks like the contacts are spaced slightly differently, like robert described. I’m returning it for a refund, and I’ll try another one.

I’ve replaced the battery with an aftermarket one, but now I’ve attached the charging cable and it just buzzes every 2 seconds. No charging progress, no boot screen. I can’t find any mention of this anywhere, but my guess is it doesn’t detect the battery. Anyone see this before? I might have to open it up again and reseat the battery, and those tiny T5 screws are a pain — the worst part was getting them back in, they kept getting attracted by the magnetic charger!

The biggest problem I had with my ZenWatch 2 is that it would stop getting notifications. I found two solutions for that, one that fixes the issue and one that prevents it.

I found that I can fix the issue by force quitting the Wear app on my phone. Really. That’s it. Everything else (rebooting the watch, resetting the watch) didn’t help. My guess is that the app is taking up too much memory, as I assume when you check a notification on your watch, it fetches the info from the phone app.

So, the way I now have prevented that from happening is just clearing notifications constantly. That seems to keep the Wear app from running out of memory or whatever happens when it stops sending notifications. Or maybe the watch memory is too full to receive them. Either way, it seems to be a memory issue.
