An unknown percentage of the first owners of AirPods face problems of battery life with the charging case, which was designed to extend the duration of five hours of wireless headphones up to 24 hours.
According to a thread on Reddit, the charging case a customer went from a full charge of 100 percent to fifty percent just after leaving their AirPods shitting all night.
He also reported this problem to Apple support and received a replacement drive. It should be noted that they could not tell you how long the carrying case should last when the AirPods are not in use. Batteries, of course, lose charge over time, but losing the full charge in two days with the AirPods inside the case is definitely an indicator of some sort of anomaly.
This user confirmed that the unit you received works fine and that you no longer have the problem of excessive draining of the battery.
The charging case was obviously designed to recharge AirPods and as an extra, lets you quickly check the power levels of both headphones simply holding the lid open and leaving the case to two centimeters away from your iPhone.
It is possible that other affected users may have a defective charging case, and in that case a quick trip to an Apple store must resolve their problems because the company has a standard 1 year warranty that guarantees free replacement due to any manufacturing defect .
If you own a pair of AirPods and your carrying case shows symptoms of excessive battery loss, do not hesitate to consult Apple's online technical support, or better yet, go to one of the nearest physical stores to order A replacement.
