Abstract
A mobile phone that uses OS virtualization for minimizing power consumption in mobile phones is provided. Apparatus and methods may involve conserving processor power in a mobile phone according to the invention may include the following steps. A first step may be awakening a first processing core from a low power state in response to a first operating system (OS) thread. A following step may include processing the first OS thread using the first processing core. A next step may include determining whether utilization of the first processing core over a first time period has exceeded a predetermined threshold. The method may also include awakening a second processing core from a low power consumption state if utilization of the first processing core over a first time period has exceeded a predetermined threshold.
