It's a third party app so not everyone has it.
While it definitely looks like some folks are getting relief by removing it, it's definitely not the underlying issue with the 10.X updates.
I removed Paprika 3 (a recipe app) and Spotify (I never use) from my watch yesterday after reading this thread. My watch died at around 8.5 hours and took over 4 hours on the charger to turn back on after dying last night. After that time, it was only at 16% battery and then seemingly charged normally overnight.
This morning I took it off the charger at 7am and it is now at 76% battery as of writing this. I have not directly used it for anything today except passive time checking.
While I can appreciate that these issues point to a bad battery, none of this was happening until the 10.X updates rolled out. My watch was working, charging and holding a charge perfectly fine until then.
