8. Shut off unnecessary push notifications.
8. 关闭不必要的推送通知
Both Apple and Google recommend disabling push notifications, which are essentially app alerts, to conserve battery life. Notifications require regular communication with notification servers, and each notification causes your phone to wake up for a few seconds, including turning on the screen, to show you a message and give you a chance to act on it.
为了节省电能,苹果和谷歌都建议关闭推送通知,特别是那些应用的通知。要接收这些通知,需要经常与发送通知的服务器通讯,每条通知都会令你的手机从睡眠状态中醒过来几秒钟,屏幕会亮起来,给你显示一条消息,让你做出回应。
