Kind of a dopey question… will this work if I keep my phone in my camelback while riding? I don’t want to attach it to my handlebars.

Yeah watched some videos and clearly the answer would be no. What’s the model of top-tube phone mount you used?

Just use a bike computer - it's the superior tool for the task in every way. Wahoo, Garmin, Hammerhead - there are excellent options out there.
