That way I don't have to take my phone out of my case (Nuud) to use it for my cycle computer. It's really the perfect setup.
So here's what I have:
iPhone 5S with Wahoo Fitness App
Lifeproof Nuud Case
Lifeproof bicycle mount
Wahoo Blue HR
Wahoo Blue SC
I really love this setup. Mine has never dropped the sensors. The only con I see is battery life will be good for roughly 4 hours. After about 3:15 I have roughly 50% battery life. The only way I could get that time out of it was to turn the brightness down as low as I could barely read the screen, which was ok. But I just ordered a 6000mAh portable battery charger...
Amazon.com: AnkerŪ 2nd Gen Astro 6000mAh (2A Output) Portable Charger External Battery Pack with PowerIQ™ Technology for iPhone 5S, 5C, 5, 4S, iPad Air, mini, Galaxy S5, S4, S3, Note 3, Galaxy Tab 3, 2, Nexus 4, 5, 7, 10, HTC One, One 2 (M8),
To each his own but I think it will be the perfect setup for me.
With this setup I was able to get 17 hours, 13 minutes with my first test, way more time than I need:, here's my results if you're interested:
Test 1: This test was off the bike, with the phone's screen on 100% of the time and at 100% brightness, and the Wahoo fitness app on with bicycle workout started, and wifi and bluetooth on with bluetooth connected to headset streaming music. This test was not actually on the bike. The ext batt claims 3 full charges for iPhone 5S. I was able to get 2 full charges and a piece, but that's because for the 2 hours the unit was charging, the ext battery was also supplying current for the phone which was high with the screen on and at 100%, gps running, bluetooth, etc.

Test 2: This test was on the bike during an actual workout, with Blue HR and Blue SC sensors. The Wahoo fitness app on with bicycle workout, and wifi and bluetooth on with bluetooth connected to headset streaming music. The phone's screen was on 100% of the time and at varied brightness, mostly low to medium. The first 30 minutes was at the lowest brightness setting because it was before dawn. After I increased brightness to only what was neccesary to see speed, distance, etc. A few times I had to reduce the brightness manually I think because auto-brightness would raise it automatically. Next time I'll try it with auto-brightness off.
