Abstract

Systems, methodologies, and devices are described that can facilitate reducing power consumption associated with mobile devices. A mobile device can utilize a sleep mode controller that can facilitate selecting and/or switching to a desired sleep mode based in part on predefined sleep mode criteria. The sleep modes can include a non-sleep mode, light sleep mode, and/or deep sleep mode. The mobile device can employ an analyzer to evaluate information related to explicit signals, implicit signals, and/or the current sleep mode to determine whether a condition is met based in part on the predefined sleep mode criteria such that a transition to a different sleep mode is to be performed. If such a condition is met, the sleep mode controller can facilitate transitioning from the current sleep mode to a different sleep mode to facilitate reducing power consumption by the mobile device.
