Despite using batteries and wireless charging technology, Apple decided not to incorporate wireless charging into AirPods. This makes recharging your earphones a bit more of an inconvenience compared to other wireless earbuds. This is because you can only recharge your AirPods by placing them in their charging case. And whenever you place your AirPods in their case for recharging, the indicator light on top turns into a flashing amber light that signals that they are currently being charged.
