In the Wirecutter’s testing, receiving a few dozen notifications over the course of an hour didn’t noticeably affect battery usage. But if you get a lot of notifications each day, that energy use can add up. If a particular app or service (say, Twitter or your email client) is constantly producing notifications, consider disabling notifications for that app.

根据Wirecutter的测试，在一小时内接收几十条通知不会明显影响电池用量。但是如果你每天都要接收大量推送通知，累计的电量就相当可观。如果某个应用或服务（比如Twitter或你的邮件客户端）经常制造通知，那就考虑关闭这个应用的通知吧。

On an iPhone, open the Settings app, tap Notifications, tap the app name and disable Allow Notifications. On Android, disable notification in an app’s settings menu, or long-press the notification itself and select the “i” icon. This will send you to that app’s App Notifications settings, where you can block all notifications.

在iPhone手机中，打开“设置”，点击“通知”，点击这个应用的名字，关闭“允许通知”。在安卓系统中，可以在该应用的设置菜单里关闭通知，或者长按这个通知，并选择上面的“i”图标。它会带你进入这个应用的“应用通知”设置，你可以在这个菜单里关闭所有通知。
