Thanks, you are correct. I tried again a few hours later from home (about 50 miles away from my initial test) and it locked within 30 seconds.
Edit: I've had it plugged into my MBP to charge for about 35 minutes and it still said 80%. After turning it completely off and back on fixed this (now says 100%).
Edit2: I really wish I could play music via bluetooth with this.
