Only been using the 810 for about a week now, so YMMV.
When using my phone (iPhone 5S) + blue SC on the Strava app with my phone turned off (normally keep it in my bento box) I would hit probably around 20-30% battery life after a 40 mile ride. This wasn't too bad but I don't like to cut it that close as I do generally ride alone and who knows.
I initially was looking at the RFLKT+ but I realized I was about to spend another $120 and be in the same spot with battery life. I also wanted turn by turn directions because it was a pain to keep having to pull my phone out to see where to turn next (and turn by turn on the phone would kill battery life even quicker). Since I already had the garmin cadence + HR sensor from an old running watch I just decided to bite the bullet.
Short test with a 15 mile ride yesterday left my Garmin with 75% battery life left. And that's after not charging it and using it for my commute on Monday and Tuesday (~2.5 miles each way if I take the light rail). Will be giving it a more thorough test this weekend
