Abstract: The invention concerns a casing arrangement, comprising a casing bottom part having a recess configured to accommodate a rechargeable electronic device therein; and a casing top part configured to be attached to the casing bottom part for covering the rechargeable electronic device accommodated in said recess. A sensor unit is arranged in the casing bottom part and configured to provide a status signal in response the casing top part being attached to the bottom part. The casing bottom part is configured to recharge the electronic device when accommodated in the recess based on a respective recharging signal provided by a charge control circuit. The charge control circuit is configured to hibernate the electronic device and terminate any recharging of the electronic device in response to the status signal indicating that the casing top part is attached to the casing bottom part and a pre-determined charging state of the electronic device.
