A mobile wireless communications device may include a near field communication (NFC) device operable in a first NFC mode or a second NFC mode, wherein the second NFC mode has a lower power consumption level associated therewith than the first NFC mode. The mobile wireless communications device may further include a processor coupled with the NFC device and capable of detecting a field change via the NFC device when the NFC device is in the second NFC mode, determining a condition of the mobile communications device, and switching the NFC device from the second NFC mode to the first NFC mode based upon the field change and the condition. |
