Title: (ZH) 降低智能手机通话中功耗的方法
Abstract: front page image
(ZH)

本发明公开了一种降低智能手机通话中功耗的方法,包括以下步骤:手机进入通话;手机贴近耳朵遮蔽距离感应器PS且无其他模块占用系统wakelock;手机黑屏,CPU进入休眠状态;手机离开耳朵距离达到阀值后距离感应器PS向CPU上传中断信号;唤醒中央处理器CPU;中央处理器CPU控制点亮屏幕。本发明在通话过程中采用外部中断方式唤醒手机,在通话过程中让CPU处于休眠状态,在手机离开耳朵达到一定距离时再通过PS中断唤醒CPU,在不影响用户体验和系统功能及成本的情况下,可节省通话过程中功耗电流30mA~35mA,降低通话功耗25%左右,对整个系统特别是打电话较多的情况下的手机续航能力有较大提升。
