adjusting a display of the mobile device based on at least the detection of the wireless connection;
wherein adjusting the display comprises turning off power to a pixel array of the display.
2. The method of claim 1 , wherein adjusting the display comprises reducing a refresh rate of the display.
3. The method of claim 1 , wherein adjusting the display comprises turning off a backlight of the display.
4. The method of claim 1 , wherein adjusting the display comprises adjusting a brightness level of a backlight of the display.
5. The method of claim 1 , further comprising detecting a connection between the mobile device and an external power source, and wherein adjusting the display comprises maintaining the display in a powered on state.
6. The method of claim 1 , further comprising detecting at least one property of the external display device.
7. The method of claim 6 , wherein the at least one property comprises whether the external display device comprises a touch-screen display or the external display device comprises a non-touch screen display.
8. The method of claim 7 , further comprising adjusting the display of the mobile device based on the detected at least one property.
9. The method of claim 1 , further comprising setting the mobile device to a first state when initially connected to the external display device, and setting the mobile device to a second state when initially disconnected from the external display device.
10. The method of claim 9 , wherein the first state is different than the second state.
11. The method of claim 9 , wherein the first state is substantially the same as the second state.
12. The method of claim 1 , further comprising adjusting the display of the mobile device based on a battery charge level of the mobile device.
13. The method of claim 1 , further comprising adjusting the display of the mobile device based on input from a user.
14. A mobile device comprising:
a display; a first processing circuit configured to detect a wireless connection with an external display device; and
a second processing circuit configured to adjust the display based on at least the detection of the wireless connection;
wherein the second processing circuit is further configured to turn off power to a pixel array of the display.
15. The mobile device of claim 14 , wherein the second processing circuit is further configured to reduce a refresh rate of the display.
16. The mobile device of claim 14 , wherein the second processing circuit is further configured to turn off a backlight of the display.
17. The mobile device of claim 14 , wherein the second processing circuit is further configured to adjust a brightness level of a backlight of the display.
18. The mobile device of claim 14 , further comprising a third processing circuit configured to detect a connection with an external power source, and wherein the second processing circuit is further configured to maintain the display in a powered on state if at least the connection with the external power source is detected.
19. The mobile device of claim 14 , further comprising a third processing circuit configured to detect at least one property of the external display device.
20. The mobile device of claim 19 , wherein the at least one property comprises whether the external display device comprises a touch-screen display or the external display device comprises a non-touch screen display.
21. The mobile device of claim 20 , the second processing circuit is further configured to adjust the display based on the detected at least one property.
22. The mobile device of claim 14 , further comprising a third processing circuit configured to set the mobile device to a first state when initially connected to the external display device, and further configured to set the mobile device to a second state when initially disconnected from the external display device.
23. The mobile device of claim 22 , wherein the first state is different than the second state.
24. The mobile device of claim 22 , wherein the first state is substantially the same as the second state.
25. The mobile device of claim 14 , wherein the second processing circuit is further configured to adjust the display based on a battery charge level of the mobile device.
26. The mobile device of claim 14 , wherein the second processing circuit is further configured to adjust the display based on input from a user.
27. An apparatus comprising:
means for detecting a wireless connection between a mobile device and
an external display device; and
means for adjusting a display of the mobile device based on at least the detection of the wireless connection;
wherein the second processing circuit is further configured to turn off power to a pixel array of the display;
wherein the means for adjusting is further configured to turn off power to a pixel array of the display.
28. The apparatus of claim 27 , wherein the means for adjusting is further configured to reduce a refresh rate of the display.
29. The apparatus of claim 27 , wherein the means for adjusting is further configured to turn off a backlight of the display.
30. The apparatus of claim 27 , wherein the means for adjusting is further configured to turn adjust a brightness level of a backlight of the display.
31. A non-transitory computer program product, comprising:
non-transitory computer-readable medium comprising:
code for causing a computer to detect a wireless connection between a mobile device and an external display device; and
code for causing a computer to adjust a display of the mobile device based on at least the detection of the wireless connection;
wherein the computer-readable medium further comprises code for causing a computer to turn off power to a pixel array of the display.
32. The computer program product of claim 31 , wherein the computer-readable medium further comprises code for causing a computer to reduce a refresh rate of the display.
33. The computer program product of claim 31 , wherein the computer-readable medium further comprises code for causing a computer to turn off a backlight of the display.
34. The computer program product of claim 31 , wherein the computer-readable medium further comprises code for causing a computer to adjust a brightness level of a backlight of the display.
