Hi guys I've been riding for around 2 years and started getting serious... (Ish) I started with the iphone 5 with a lifeproof case and bike mount. Run that with a wahoo hr monitor and a cadence and speed monitor. They work really well, I even use bluetooth earphones to listen to music at the same time. HOWEVER - enter battery life. Having the screen on drains battery life like crazy! So I pocketed the phone and setup voice alerts. Worked for a while, but still only gets me 3-4 hrs battery life. So then turn off data on the phone when riding - this gets you another hour or so.. BUT I still wanted to see the real time feedback. So I bought the rflkt+ from wahoo which is almost a dumb screen for the phone. Enter more battery life. it also have a altimeter and temp gauge - to make some of my gps strava climbs real... I now have 2 cadence monitors (1 for mtb one for road) and one hrm (I killed one by sending one to the wash) Bottom line is that I'm now doing rides over 6 hrs... Which means even with a extra battery some times I don't complete the ride officially cause my battery dies - this sucks because if it's not on strava it didn't happen!! Basically the iphone route is great if you don't plan on doing any rides over 5-6 hrs... After that I'd go garmin or suunto/polar. There is another thread that sums up iphone vs gps. There are two types of people in the world - those who go with a dedicated gps for the beginning, and those who try the iphone route and then buy a gps... I'm inclined to say that you fall in the second class if you plan on rides over 5 hrs On that note, anyone want some wahoo tech for a good price? also check out cycle meter app, gives you all the analysis you would ever want.
