My new F5+ sapphire arrived yesterday! I'm upgrading from an F5 with the mineral crystal in slate gray. It was completely dead when it arrived, so I had to let it charge for a while before it would start up. After it did, I spent several hours playing with it, installing the missing apps, syncing with True Up and upgrading the maps.
Sitting these two watches side by side, you could never pick out which was which by looking. The F5+ in black looks almost identical to the F5 in slate gray, with some minor differences concerning what's printed on the bezel. Some people have reported that the sapphire crystal makes the watch face look a bit darker but I compared in a few different lighting conditions and couldn't see a difference. One of the first things I did was to fool with the run widget. I was cycling through the pages so I could add my custom ones and noticed the map page. That's cool! Frankly I doubt I would ever use it running. I might if I get lost cycling, but its very cool. I also noticed that there are some new exercise widgets, like stair climbing and such. Perhaps those were there with the F5, I don't recall. Only one of my apps - a sailboat start timer app - refused to run. That's a good app, so I hope the developer fixes it.
I also installed my spiffy watch faces and my aftermarket orange strap. The strap fit perfectly, which I expected. The watch face looks exactly as it does on the F5.
Then I loaded some music onto it. I'm not thrilled that to use Spotify with this watch I have to pay them $10 per month, but at least I can manually load my music. I paired it with my Jaybird X2 bluetooth headset and it worked as expected, sounding good. I did notice that there does not seem to be a way to actually turn the music off, short of pausing it. Perhaps this has to do with the battery life issues being reported?
The watch face I use updates only once per minute. I let the F5+ charge all night, so I'll be able to get an idea of the battery life vs the F5. During the winter, when I'm not doing much outside, I would get great battery life from the F5, as in nearly three weeks between charges. That's with the OHR running al the time, bluetooth connection to my phone for texts and alerts and the occasional GPS activity. Hopefully I'll see comparable battery life. Fingers crossed!
