APPARATUS AND METHOD FOR REDUCING POWER CONSUMPTION IN PORTABLE TERMINAL
First Claim
1. An electronic device comprising:
- a memory;
a first processor; and
a second processor configured to;
control to operate, while the first processor is in a sleep state, a sensor of the electronic device that obtains motion information of the electronic device,control to determine that the electronic device is moving or stationary based on the motion information, andcontrol to write the motion information in the memory,wherein the first processor is configured to read the written motion information from the memory based on the first processor being awakened.

Abstract
An apparatus and method for reducing power consumption of a portable terminal are provided. More particularly, an apparatus and method for reducing power consumption generated in an idle state in order to solve a power consumption problem in a portable terminal are provided. The apparatus includes a state determination unit which is configured independently from an application processor for controlling applications and which wakes up when entering an idle mode to allow the application processor to sleep, and thereafter determines a state of the portable terminal, and if it is determined that the portable terminal escapes from the idle mode, allows the application processor to wake up.
