8. A method of extending the battery life of a mobile device providing content wirelessly, comprising:
-
initially setting at least one parameter controlling an encoding of said content at a relatively high level of quality; detecting when a low battery condition exists; and in response to said detecting, adjusting said least one parameter to decrease said quality. - View Dependent Claims (9, 10, 11, 12, 13, 14)
