I've been a long time RunKeeper and Spotify user on my old Droid Bionic. When I picked up my Moto-X, I wanted to go on runs, business as usual. I'm now experiencing a repetitive issue. Around mile 3, before I hit 4, my phone will shut off. This has happened on my last three consecutive runs where I now know it's a problem. Has anyone else experienced this? I've tried uninstalling and reinstalling both of those apps. I've restarted my phone. I went on a run tonight, phone shuts off at 3.44 miles. This is very frustrating for me. I just don't know if it's an issue with an app, both apps playing nicely together, or my phone's handling of these two apps. I do not experience a phone shut off at ANY other time. Input in appreciated. I would love to resolve this issue and continue to enjoy my exercise uninterrupted.
