The new AirPods headphones are rated at 20 hours play time with noise cancellation enabled, how do you figure 2+ cycles per day? Or are you talking about the earbuds AirPods?

I get that earbuds' 5-hour listening time is borderline annoying and if it drops to 3 or 4 hours you've got a real usefulness problem, but 20 hours has quite a lot of headroom for battery degradation unless you don't sleep.
