It won't even make it through a day now after jailbreaking.

I actually get 3 days use out of my watch now that I have update to OS2 and iOS 9 jailbroken. Previously I was getting 2 days use.
 
mine actually has been dying after like 8 hours as well and i dont even use it for anything but as a watch. not sure if its jb related though. could also be the watch OS 2 update (already tried repairing twice)
 
yea, i noticed this too. i removed tetherme and went right back to normal battery life on the watch.

if you have that, it could be the issue.
 
There is a bug in watch OS2 which doesn't turn off the sensor properly after using Siri to invoke the heart rate monitor (according to the latest patch notes from Apple). That's probably what some of us are seeing here, I too have now noticed bad battery life (on one day) and I think I had manually used the heart monitor glance. It maybe that just the act of putting the watch back on charge kills the heart rate monitoring too, and this clears the bug, as the next time I used the watch (after charging it) it went back to getting 3 days use again.

By the way you can still update the watch to the latest watch OS version without having to upgrade to iOS 9.1, I've just updated while still on 9.0.2
