蘋果高層正式迴應:關閉iPhone後臺不會更省電

If you're still painstakingly killing all your apps in the hopes of squeezing out some extra battery life from your iPhone, you can officially stop.

如果你還在煞費苦心地通過關閉所有應用程序來爲你的iPhone電池延長一點點壽命的話，那麼現在你可以正式收手了。

Apple's iOS chief Craig Federighi has dispelled the myth that force closing your iPhone apps will help save your battery. The executive confirmed that killing apps isn't necessary for your battery and said that he is not in the habit of closing his apps.

蘋果iOS總監克雷格·費德里吉已經澄清了關於強行關閉iPhone應用程序能夠節約電池壽命的傳言。費德里吉證實：關閉切換的應用程序對延長你的電池壽命並無益處，同時也表示自己也沒有隨時關閉後臺應用的習慣。

Federighi, who oversees iOS and OS X, was responding to an email sent by an Apple customer to CEO Tim Cook when he made the comments. In the email, which was first published by 9to5Mac, the customer asked Cook, "do you quit your iOS multitasking apps frequently and is this necessary of battery life?"

費德里吉平常負責監督iOS和OS X開發，此前一位蘋果手機用戶在對產品進行反饋時向蘋果公司CEO蒂姆·庫克發送了一封郵件，費德里吉對這位顧客進行了回覆。該郵件最先由9to5Mac網站公佈，在郵件中，這位蘋果用戶詢問庫克：“你會不會經常隨時關閉你的iOS的多任務應用程序，這對於提高續航是否有效？”

Though the note, dated March 6, was sent to Cook, Federighi weighed in the next day with a simple answer. "No and no," he wrote.

雖然這封郵件於3月6號發給的庫克，但最後卻是費德里吉在第二天代勞給予了回覆。針對這位用戶提出的兩個問題，費德里吉的回答都是“no”。

This is far from the first time this particular myth has been debunked. Apple's own support page even states that "generally, there's no need to force an app to close unless it's unresponsive."

這並不是蘋果公司第一次澄清這個傳言。蘋果在自己的幫助頁面甚至專門進行了聲明：“一般來講，沒有必要強制關閉後臺應用程序，除非手機出現卡頓等情況。”

That's because, as 9to5Mac and others have pointed out, most of the apps that appear in the multitasking view when you double press the home button aren't actually running in the background.

正如9to5Mac網站和其他媒體所言，不用關閉後臺的原因在於，當你雙擊手機主畫面按鈕時，顯示在屏幕列表上的大多數應用程序並沒有真正運行，只是你在過去已經打開的應用程序的靜態圖像。

Of course, it's always a good idea to check your app settings every once in awhile to make sure that the apps that are using your location actually need it — as location services tend to use up the most battery. Also, disabling background refresh on apps you don't use very much is a good idea. Some apps, like Facebook's, may be worse offenders at sucking your battery dry than others.

當然，每隔一段時間查看你的應用程序管理，以便確定正在使用定位功能的程序是否確實需要GPS這一功能倒是個不錯的習慣。因爲通常來講，這些定位服務會消耗手機大量的電量。此外，禁用那些不常用的後臺刷新程序也是一個較好的辦法。有些軟件，比如Facebook這一類軟件比其他軟件更容易消耗你的電量。
