Like many, I'm an hour or more away from an Apple Store so I haven't bothered exchanging them.
However, I have tracked their behavior in all manners described above and reset/re-paired them twice.
It really seems that the issue is with the AirPods themselves and not the "dental floss" charger. Their firmware probably guides them to anxiously hunt for the nearest Apple device whether they're in the charger or not. This results in the pods perpetually draining and topping themselves off while in the charger. I would love firmware that recognized the case/charger, stopped the pods from hunting (unless the lid was open), topped them off, then let them be (pods at 100% with no lightning bolt charge indicator and no further drain on the case/charger).
One would think Apple would have ironed out this behavior in firmware, prior to release.
I suspect they'll only acknowledge the issue quietly, via the release notes of a firmware update, "resolves battery drain experienced by 'some' users." I'd also guess that the firmware update will only arrive with iOS 10.3 and not 10.2.x
Until then, early adopters can look forward to perpetual "conditioning" of their tiny AirPod batteries, likely diminishing their ability to retain a charge (5 hours becomes 4, 3, 2, 1 ... time for new AirPods... just what Apple wants...).
While the AirPods themselves are generally cool, this battery issue, others like it, and Apple's increasingly tiresome, corporate response to such issues is not.
