Wondering How Long Do The Airpods Last? Well, let me break it down for you. The battery life of AirPods gets shorter as time goes by. This happens because the battery capacity goes down, which also makes them work less well overall. It’s just how lithium-ion batteries in small gadgets like these behave – nothing out of the ordinary. As the battery gets weaker, you might find yourself needing to charge them more often to keep them powered up.
