My AirPods case is constantly losing charge, even when the pods have 100% battery.
Yesterday night I charged both case and pods and disconnect them once it was fully charged (around 10pm). In the morning (7am) the case had 67% and at 11am it has 56%.
This has been a regular situation. This is not a residual loss, the case is constantly draining charge, even when the pods are fully charged.
