Abstract: Embodiments of the present invention are capable of lowering touch scan rates in a manner that conserves power resources without compromising performance or user experience thereby promoting battery life. Embodiments of the present invention perform touch scan operations using a touch sensitive panel at a first scan rate. In response to certain events automatically detected within the mobile device (e.g., when a full-screen video is being displayed), embodiments of the present invention may then perform touch scan operations at a second scan rate that is slower than the first scan rate that also consumes less power compared to the first scan rate. As such, for events or use cases in which limited user interaction with the touch sensitive panel is typical, embodiments of the present invention may lower touch scan rates in a manner that still enables users to interact with applications (e.g., interaction with playback controls during video playback) and promotes efficient power usage and extends battery life.
