  • METHODS AND APPARATUS FOR DYNAMICALLY ADJUSTING A POWER LEVEL OF AN ELECTRONIC DEVICE
    Publication number: 20140157026
    Abstract: Methods and apparatus for dynamically adjusting a power level of an electronic device (100) are disclosed. In an embodiment, an electronic device (100) receives a usage pattern of the electronic device (100) (e.g., typically used 9:00 AM to 5:00 PM on weekdays). The electronic device (100) then dynamically adjusts a wake up timer (204) associated with the electronic device (100) based on the usage pattern (e.g., expire at 8:50 am the next morning, which is 10 minutes before usage typically resumes for that day). In response to an expiration of the dynamically adjusted wake up timer (204), the electronic device (100) increases the power level of the electronic device (100) (e.g., transition from hibernate mode to standby mode, possibly via other intervening power modes, for faster startup in anticipation of resumed usage).
