Abstract
A method (150) and device (200) adapted to run an application in synchronous communication with an application server is described. The method (150) can include the steps of: detecting (155) motion in proximity to the mobile computing device; and adjusting (160) a synchronization interval between the mobile computing device and a server in response to the detected motion. The method and device can provide substantial energy savings in an energy storage device for a mobile computing device and provides a useful compromise for energy conservation on one hand, while also accommodating a user's demand for a short synchronization interval when desired, on the other.
Claims23
A method for lengthening the battery life of a mobile computing device running an application in synchronous communication with an application server, comprising the steps of:
- detecting motion in proximity to the mobile computing device, and
- adjusting a synchronization interval between the mobile computing device and a server in response to the detected motion.
A mobile computing device configured with an energy storage device, comprising:
- a housing;
- a controller coupled to the housing, the controller configured to run an application in synchronous communication with an application server;
- memory coupled to the controller;
- a wireless transceiver coupled to the controller for synchronizing application data between the mobile computing device and the application server;
- a motion detector configured to detect motion in proximity to the mobile computing device;
- and
- a power saving module configured to adjust a length of a synchronization interval between the mobile computing device and the application server in order to conserve energy of the energy storage device, in response to the motion detector.
The mobile computing device of 13, wherein the motion detector comprises at least one of an accelerometer, a magnetic field sensor, a compass, a proximity sensor, and a light sensor.
