First Claim
1. A method performed by a mobile communications device, the method comprising:
- receiving from a user of the mobile communications device an indication that the mobile communications device is to place a telephone call to a particular recipient via a mobile telephone network;
placing the telephone call to the particular recipient via the mobile telephone network;
automatically evaluating a battery charge level of the mobile communications device;
transmitting an indication of the battery charge level to the recipient of the telephone call via the mobile telephone network;
automatically evaluating a transmit power being used by the mobile communications device to communicate via the mobile telephone network; and
transmitting an indication of the transmit power to the recipient of the telephone call via the mobile telephone network;
receiving, from the recipient of the telephone call via the mobile telephone network, an instruction to turn off one or more specified capabilities of the mobile communications device; and
in response to the received instruction, turning off the one or more specified capabilities, wherein turning off the one or more specified capabilities increases the amount of time the mobile communications device can sustain the telephone call.

Abstract
Systems and methods of conserving power in a mobile emergency communication device. After placing a telephone call, the calling device communicates information to the call recipient, for example a response center, usable to estimate the remaining talk time of the calling device. The call recipient sends instructions to the calling device to turn off, disable, or suspend certain device capabilities to conserve battery power in the calling device. For example, if it is determined that the device is not moving, a geographical location capability of the device may be turned off to conserve power. Other capabilities may also be turned off, for example a secondary radio transceiver, a display screen or other visual indicator, certain software applications executing on the device, or other capabilities.
