When I first opened up my AirPods, I noticed a few things, after pairing them to the iPhone7+ (using the Apple method). • The headphones arrived with 35%/36% and the case was 35% I let the case charge the AirPods and I plugged the case into the lightning port. I noticed: • AirPods charged and the case drained down to 25%. • Even though the case was plugged in, the case did not charge. • I plugged the case in for the first 24h (without AirPods inside) and the case did not charge. The case eventually did charge. This led me to think about this: Is the case chargeable, while charging? Enough power draw for full charge of both AirPods and case?
