| 发明名称 | Mobile device having enhanced in-holster power saving features using NFC and related methods | ||
| 摘要 | A communications system may include a holder, a first near-field communication (NFC) device carried by the holder, and a mobile device. The mobile device may include a housing configured to be removably positioned within the holder, a second NFC device carried by the housing and configured to communicate with the first NFC device via NFC communications, and a controller carried by the housing and coupled to the second NFC device. The controller may be configured to operate the second NFC device to scan for the first NFC device in a first mode when the housing is removed from the holder, and operate the second NFC device in a second mode based upon communication with the first NFC device when the housing is positioned within the holder, where the second mode has a lower power consumption level associated therewith than the first mode. | ||

| 主权项 | 1. A communications system comprising: a holder; a first near-field communication (NFC) device carried by said holder; and a mobile device comprising a housing configured to be removably positioned within said holder,a second NFC device carried by said housing and configured to communicate with said first NFC device via NFC communications, anda controller carried by said housing and coupled to said second NFC device and configured to operate said second NFC device to scan for said first NFC device in a first mode using electromagnetic (EM) carrier field pulses having a pulse width of a first duration when said housing is removed from said holder, andoperate said second NFC device in a second mode using EM carrier field pulses having a pulse width of a second duration shorter than the first duration based upon communication with said first NFC device when said housing is positioned within said holder, the second mode having a lower power consumption level associated therewith than the first mode, wherein said second NFC device draws a current in a range of 4-5 mA when operated in the first mode and a range of 15-150 μA when operated in the second mode. | ||
