Be on the lookout for apps that are active for extended periods in the background and are using a lot of battery power. Examples include an email app that spends lots of time checking for new messages even when your phone is asleep, a news reader that updates articles in the background or a fitness app that constantly monitors your location.
要注意那些在后台工作了很长时间,耗费大量电量的应用。比如某个邮件应用,在你的手机处于睡眠状态时,还花了很多时间检查新信息、某个新闻阅读应用在后台下载了大量文章,或是某个健康应用经常在监测你的位置。
If you find apps using up lots of energy in the background, disable their background activities. On an iPhone, go to the Settings app, tap General and then Background App Refresh and disable the background activities for any apps. On Android, go inside the Settings app, tap Data Usage, choose an app, then select “Restrict Background Data” for background data usage.
如果你发现某个应用在后台使用了大量电量,那就禁用它的后台活动。在iPhone上,可以打开“设置”,点击“通用”,再点击“后台应用刷新”,禁用这个应用的后台活动。在安卓系统下,可以进入“设置”,点击“数据使用”,选中这个应用,之后选择“限制后台数据”,就可以限制后台数据的使用了。
