Google延長電池續航力的專利

根據USPTO所公告的專利資料顯示,Google串請了一個可以使Android手機自動檢測電池電量,在電量很低的情況下,可以藉由改變螢幕解像度等方式,延長電池續航時間的專利。該專利延長電池續航力的方式有三:
1.關閉液晶螢幕的模糊和動畫(Blur and Animations)功能。
2.關閉模糊和動畫功能,並降低螢幕解析度。
3.關閉模糊和動畫功能,降低螢幕解析度,命令螢幕只顯示黑和紅兩種顏色。

Title : Power saving techniques for battery-powered computing devices
Filing Date : 2012.7.12.
Issue Date : 2013.3.26.
Abstract :
A computer-implemented technique is presented. The technique can include determining, at a computing device including one or more processors, a power remaining in a battery of the computing device. The technique can include determining, at the computing device, a selected operating mode from a plurality of operating modes for the computing device based on the power remaining in the battery. Each of the plurality of operating modes can correspond to a different range of power remaining in the battery of the computing device. The technique can also include adjusting, at the computing device, operation of the computing device based on the selected operating mode. The selected operating mode can be associated with one or more display functions of the computing device, and adjusting operation of the computing device can include adjusting operation of the one or more display functions to adjust power usage of the computing device.
