Abstract: A communication device, and battery there for, are provided. In at least one of the battery and the communication device is provided a magnetic shield portion for routing magnetic flux away from the receiver when the radio is in operation. The magnetic shield portion can be incorporated into at least one of the battery and the communication device. When the battery is inserted into mobile communication device, the magnetic shield portion is located substantially between a battery portion, in the battery, and the receiver.

Abstract: A method and system to charge efficiently and safely batteries that power an electronic device and are comprised in an electronic device. The method and system performs measurement of electrical currents flowing in different branches of an electrical circuit that comprises the batteries and determines if there if there is a battery connection fault. The charge current used to charge the batteries is adjusted in accordance with the detected fault or absence thereof, in order not to exceed a safe current limit.
