In August 2016 Apple directed AirPods Testing which was directed at using Airpod units that were preproduced and matched programming with iPhone 7 units that were also programmed and preproduced. The playlist volume was set to only half and the testing utilized full Airpods battery release while playing music until playback was ceased by the main Airpod. It was observed that the life of the battery relies on the setting of the gadget, how it is utilized and a number of other elements. After the Airpods were depleted they were charged for thirty (30) minutes, and then sound was played again until playback was once again ceased by the primary Airpod. This cycle continued until both the charging case and the Airpod were released completely.
