[00:10.04]Even if you did not add new apps to your phone, [00:14.52]an app update alone can use lots of battery power. [00:20.76]But you can check your apps to see how much battery they have been using. [00:26.92]If an app you do not use much requires a lot of battery power, [00:32.84]you might want to remove it from your phone. [00:37.36]To check an iPhone or iPad, open the Settings app, then go to Battery. [00:44.80]Recent battery use percentages for each app will appear. [00:50.56]The device measures use in the last 24 hours and last seven days. [00:58.88]You can also see whether an app has been using battery life to update. [01:04.72]Tap on the clock icon for either last 24 hours or last seven days. [01:13.04]That will show how much time the app has been open on your screen [01:19.04]and how much time it has spent working. [01:24.12]Android phones can show you which apps have used the most battery recently. [01:30.92]Note that different versions of the Android operating system may have different settings. [01:37.52]Open the Settings app. Tap Battery. [01:42.34]In older Androids, go to Settings, then Device, then Battery. [01:49.16]Another path might be Settings to Power to Battery Use. [01:55.76]Scroll down to see which phone functions are using your battery most. [02:01.80]The list will include recently used apps. [02:05.92]Each app has a percentage to show you how much battery it has used lately. [02:12.44]You may see an app that has used a lot of battery [02:16.72]although you have not used the app much. [02:20.80]You can force a stop to that app to prevent it from using more battery. [02:27.32]To force the app to stop, tap on it in the list. [02:31.56]A screen with a button image will appear. [02:35.44]A touch of the button will stop the app. [02:39.12]You can also report the app to Google. [02:42.72]Below the button is a list of more information [02:47.04]about how much power and data the app used. [02:51.84]I'm Caty Weaver. [02:53.52]更多听力请访问21VOA.COM
