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.

根據Wirecutter的測試，在一小時內接收幾十條通知不會明顯影響電池用量。但是如果你每天都要接收大量推送通知，累計的電量就相當可觀。如果某個應用或服務（比如Twitter或你的郵件客戶端）經常制造通知，那就考慮關閉這個應用的通知吧。

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手機中，打開“設置”，點擊“通知”，點擊這個應用的名字，關閉“允許通知”。在安卓系統中，可以在該應用的設置菜單里關閉通知，或者長按這個通知，并選擇上面的“i”圖標。它會帶你進入這個應用的“應用通知”設置，你可以在這個菜單里關閉所有通知。
