Thanks! Yea I don't notice the iphone in my shorts pocket while biking, but the note I did It wasn't awful, but I did worry about it being damaged from the motion, even though it didn't hit anything. Just the up and down in my leg pocket.
Good thought on the watch. Can you download songs from Google play music to a watch? I stream my music normally. If they is a possibility, that could work.
Never felt like I had to baby a phone in the past. I mean I take care of them, but my droids, s3, m7, iphone 5s or 6s were always sturdy and I never thought twice about them when out doing stuff. Agree, larger phones won't likely be as durable , and I always have a phone on me whether for music, GPS tracking, etc.
