I currently use my Fitbit to track my ride and have it connected to my Strava account. I ride with my phone in my pocket and can glance at my Fitbit to see basic info on times, speed, distance.
I've also ridden with a phone on the handlebars but having the screen on the whole time does affect battery life. Not a problem for short rides but something to think about before a century or longer.
I no longer obsess about speed as much as I used to and really just ride on perceived effort and check my stats after. If you're training for some event I can understand wanting more data.

I've used Quad Lock mounts for my phone on bicycles and motorcycles for the past 4-5 years. They are light and have been rock solid.
