A data collection device (DCD) is placed in a first low power mode after the DCD has been in a first predetermined position, and placed in a second low power mode after a first predetermined period of time. In another embodiment the DCD includes a wireless telephone, and a proximity sensor which detects when the DCD is close to a user's face, wherein the telephone is automatically put in a handset mode when the DCD is close to a user's face, and automatically put in a speakerphone mode when the DCD is not close to a user's face.

1. A device, comprising: a main body having a front and a back;a touch screen on the front of the main body;an accelerometer within the main body for detecting movement and an orientation of the device; anda processor within the main body configured for:determining if the device is front down or back down;if the device is front down, placing the device in a first sleep state and then a second sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the first sleep state; andif the device is back down, placing the device in the second sleep state and then a third sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the second sleep state. 2. The device of claim 1, comprising a proximity sensor within the main body for detecting the device's proximity to other objects, wherein the processor is configured for placing the device in a reduced power state in response to detecting, with the proximity sensor, that the device is close to a user's face. 3. The device of claim 1, wherein the processor is configured for, when the device is front down, placing the device in the second sleep state after a first predetermined time period in the first sleep state. 4. The device of claim 1, wherein the processor is configured for, when the device is back down, placing the device in the third sleep state after a second predetermined time period in the second sleep state. 5. The device of claim 1, wherein the processor is configured for: when the device is neither front down nor back down, placing the device in a third sleep state and then a fourth sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the second sleep state; andwhen the device is neither front down nor back down, placing the device in a fourth sleep state after a third predetermined time period in the third sleep state. 6. The device of claim 1, wherein: the processor is configured for, when the device is front down, placing the device in the second sleep state after a first predetermined time period in the first sleep state;the processor is configured for, when the device is back down, placing the device in the third sleep state after a second predetermined time period in the second sleep state;the processor is configured for, when the device is neither front down nor back down, placing the device in a third sleep state and then a fourth sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the second sleep state; andthe processor is configured for, when the device is neither front down nor back down, placing the device in a fourth sleep state after a third predetermined time period in the third sleep state;the second predetermined time period is longer than the first predetermined time period; andthe third predetermined time period is longer than the second predetermined time period. 7. The device of claim 1, wherein the processor is configured for turning off the touch screen when placing the device in the first sleep state. 8. The device of claim 1, wherein the processor is configured for turning off the touch screen when placing the device in the first sleep state. 9. The device of claim 1, wherein the processor is configured for inactivating more device functions in the third sleep state than in the first sleep state. 10. The device of claim 1, wherein the processor is configured for inactivating more device components in the third sleep state than in the first sleep state. 11. A device, comprising: a main body having a front and a back;a touch screen on the front of the main body;a proximity sensor within the main body for detecting the device's proximity to other objects;an accelerometer within the main body for detecting movement and an orientation of the device; anda processor within the main body configured for:determining if the device is front down, back down, or neither front down nor back down;if the device is front down, placing the device in a first sleep state and then a second sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the first sleep state;if the device is back down, placing the device in the second sleep state and then a third sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the second sleep state; andif the device is neither front down nor back down, placing the device in the third sleep state and then a fourth sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the third sleep state. 12. The device of claim 11, wherein the processor is configured for placing the device in a reduced power state in response to detecting, with the proximity sensor, that the device is close to a user's face. 13. The device of claim 11, wherein the processor is configured for, when the device is front down, placing the device in the second sleep state after a first predetermined time period in the first sleep state. 14. The device of claim 11, wherein the processor is configured for, when the device is back down, placing the device in the third sleep state after a second predetermined time period in the second sleep state. 15. The device of claim 11, wherein the processor is configured for, when the device is neither front down nor back down, placing the device in the fourth sleep state after a third predetermined time period in the third sleep state. 16. The device of claim 11, wherein: the processor is configured for, when the device is front down, placing the device in the second sleep state after a first predetermined time period in the first sleep state;the processor is configured for, when the device is back down, placing the device in the third sleep state after a second predetermined time period in the second sleep state;the processor is configured for, when the device is neither front down nor back down, placing the device in the fourth sleep state after a third predetermined time period in the third sleep state;the second predetermined time period is longer than the first predetermined time period; andthe third predetermined time period is longer than the second predetermined time period. 17. A device, comprising: a main body having a front and a back;a touch screen on the front of the main body;a keypad on the front of the main body;an accelerometer within the main body for detecting movement and an orientation of the device; anda processor within the main body configured for:determining if the device is front down or back down;if the device is front down, placing the device in a first sleep state and then a second sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the first sleep state; andif the device is back down, placing the device in the second sleep state and then a third sleep state based on a time elapsed without detecting movement of the device or receiving input since the device was placed in the second sleep state. 18. The device of claim 17, wherein the processor is configured for turning off the touch screen when placing the device in the first sleep state. 19. The device of claim 17, wherein the processor is configured for turning off the keypad when placing the device in the first sleep state. 20. The device of claim 17, wherein the processor is configured for inactivating more device functions in the third sleep state than in the first sleep state.
