Abstract
Disclosed is a method for dynamically invoking power saving options in a battery powered device, such as a cellular telephone, so that the period of use or run-time of the device is extended. The user settable power saving options alter operation of the device in a way that reduces power consumption and extends run-time. The power saving options define the ways by which power is saved, such as less intensity for a backlight or slower scanning for a wireless accessory, and when they are invoked, based in part on a determination of the estimated or measured actual capacity in the battery. For example when a battery is at full capacity, all features may be fully operable and as the battery discharges some of the features may be disabled or work with reduced performance.
