Abstract
The battery life of batteries of a mobile device operating in a wireless network is optimized by dynamically changing symbol rates and bits per symbol and selecting one for communicating based upon the source providing power to the mobile device.

10. A method to operate a mobile device running on battery power including the acts of:
-
monitoring the battery power;
if greater than N, N being a percentage of total power output of said battery, selecting a symbol rate lower than a maximum symbol rate at which said mobile device can operate; and
if said battery power is less than N, selecting a symbol rate which is a minimum at which said mobile device can operate. - View Dependent Claims (11, 12, 13)
