Abstract
A mobile wireless communications device includes a housing carrying a wireless transceiver and a removable power source. The removable power source includes a first Near Field Communications (NFC) circuit. A second NFC circuit is carried by the housing and is configured to authenticate the removable power source based upon communications the said first NFC circuit.

1-23. (canceled)
A mobile wireless communications device comprising:
- a housing;
- a wireless transceiver carried by said housing;
- a removable power source capable of being carried by said housing, said removable power source comprising a first Near Field Communications (NFC) circuit;
- a second NFC circuit carried by said housing, said second NFC circuit being configured to authenticate said removable power source based upon communication with said first NFC circuit;
- and
- a processor carried by said housing and coupled to said second NFC circuit, said processor operable in a locked state and an unlocked state and being configured to operate in the locked state based upon an unsuccessful authentication of said removable power source, said processor in the locked state performing a subset of mobile device functions available when in the unlocked state.
A mobile wireless communications device comprising:
- a housing defining a cavity;
- a wireless transceiver carried by said housing;
- a removable power source removably positioned within the cavity and comprising a first Near Field Communications (NFC) circuit;
- a second NFC circuit carried by said housing and configured to authenticate said removable power source based upon communications with said first NFC circuit;
- and
- a processor carried by said housing and coupled to said second NFC circuit;
- said processor operable in a locked state and an unlocked state and being configured to operate in the unlocked state based upon a successful authentication of said removable power source, and to operate in the locked state based upon an unsuccessful authentication of said removable power source, said processor in the locked state performing a subset of mobile device functions available when in the unlocked state.
A method for a mobile wireless communications device having a housing carrying a wireless transceiver and a removable power source, the removable power source comprising a first Near Field Communications (NFC) circuit, the method comprising:
- authenticating the removable power source based upon communications between a second NFC circuit carried by the housing and the first NFC circuit;
- and
- operating in a locked state based upon an unsuccessful authentication of the removable power source, and when in the locked state performing a subset of mobile device functions available when in the unlocked state.
A non-transitory computer-readable medium for a mobile wireless communications device having a housing carrying a wireless transceiver and a removable power source, the removable power source comprising a first Near Field Communications (NFC) circuit, the non-transitory computer-readable medium having computer-executable instructions for causing the mobile wireless communications device to performs steps comprising:
- authenticating the removable power source based upon communications between a second NFC circuit carried by the housing and the first NFC circuit;
- and
- operating in a locked state based upon an unsuccessful authentication of the removable power source, and when in the locked state performing a subset of mobile device functions available when in the unlocked state.
