Did you try unpairing your watch and setting up as a new one? There's been quirks associated with in-place upgrades that seem to go away when the watch is setup as new with the beta.
Oh sorry. I should have worded it better. I re-paired my watch and it's smooth sailing!
 
My location based weather now ceased to work on my Watch (OS 2 Beta 5). My own, earlier work-around does not seem to help anymore. Any suggestions, apart from possibly trying to re-boot both devices?
 
I think my favorite thing about beta 5 is that when you use Hey Siri for texts, you no longer have to respond a second time to send the message. It'll auto send if you don't tell it to not send or hit the do not send button!

And yes a re-pair has made my watch have even better including battery life which is better than when I bought it. Ended the day with 50%
 
Just a report on battery life for my 38mm sport.
With OS 1 & 1.0.1 I got about 30 hours
With OS 2 beta 4 I got about 22 hours
With beta 5 I'm getting about 40 hours!!!!!!! Around 2.5% loss per hour! Mint!!!
Anyone else?

Yes. I set up as new with OS 2 beta 4 (but not with 5) and am getting the same kind of battery life as you. With beta 4 it was totally dirt.
