A Message to Our Customers about iPhone Batteries and Performance

2017 年 12 月 28 日

致廣大用户關於 iPhone 電池及性能的説明

We’ve been hearing feedback from our customers about the way we handle performance for iPhones with older batteries and how we have communicated that process. We know that some of you feel Apple has let you down. We apologize. There’s been a lot of misunderstanding about this issue, so we would like to clarify and let you know about some changes we’re making.

First and foremost, we have never — and would never — do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades. Our goal has always been to create products that our customers love, and making iPhones last as long as possible is an important part of that.

最近，對我們在使用較早期電池 iPhone 性能表現上的處理方式，以及對這一處理方式的溝通説明，我們一直都在聽取用户的意見和反饋。有些用户因此對 Apple 感到失望，在這裏，我們致以誠摯的歉意。關於這個問題存在着許多的誤解，所以我們想向大家澄清其中原委，並向大家説明我們正在做出的一些改變。

首先也是最重要的一點，我們從來沒有、也永遠不會通過任何手段，來有意縮短任何 Apple 產品的使用壽命，更不會降低用户體驗來迫使大家升級設備。一直以來，我們的目標都是創造備受用户喜愛的產品，而儘可能延長 iPhone 的使用壽命，正是其中的重要一環。

How batteries age

All rechargeable batteries are consumable components that become less effective as they chemically age and their ability to hold a charge diminishes. Time and the number of times a battery has been charged are not the only factors in this chemical aging process.

Device use also affects the performance of a battery over its lifespan. For example, leaving or charging a battery in a hot environment can cause a battery to age faster. These are characteristics of battery chemistry, common to lithium-ion batteries across the industry.

A chemically aged battery also becomes less capable of delivering peak energy loads, especially in a low state of charge, which may result in a device unexpectedly shutting itself down in some situations.

To help customers learn more about iPhone’s rechargeable battery and the factors affecting its performance, we’ve posted a new support article, iPhone Battery and Performance.

It should go without saying that we think sudden, unexpected shutdowns are unacceptable. We don’t want any of our users to lose a call, miss taking a picture or have any other part of their iPhone experience interrupted if we can avoid it.

電池的使用壽命

所有充電電池都屬於易耗部件，其使用性能會隨着化學老化而降低，蓄電能力也會逐漸衰退。而電池充電的時間和次數，並不是影響其化學老化的唯一因素。

會影響到電池使用壽命的，還有設備的使用方式。例如，將設備放在高温環境下，或在高温環境下充電，電池就會老化得更快。這些都是電池本身的化學特性，也是整個行業內鋰離子電池的共性。

化學年齡較老的電池應對峯值負載的能力也在衰退，特別是處於低電量狀態的時候，在某些情況下，這就可能會導致設備突然意外關機。

為幫助用户更好地瞭解 iPhone 的充電電池，以及影響電池性能的各種因素，我們發佈了一篇新的支持文章《iPhone 電池和性能》。

毫無疑問，這種突如其來的意外關機是不可接受的。我們不想讓任何用户因此漏接電話，錯過拍照良機，或是影響到他們任何其他方面的 iPhone 體驗，我們希望能盡力避免這種情況發生。

Preventing unexpected shutdowns

About a year ago in iOS 10.2.1, we delivered a software update that improves power management during peak workloads to avoid unexpected shutdowns on iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE. With the update, iOS dynamically manages the maximum performance of some system components when needed to prevent a shutdown. While these changes may go unnoticed, in some cases users may experience longer launch times for apps and other reductions in performance.

Customer response to iOS 10.2.1 was positive, as it successfully reduced the occurrence of unexpected shutdowns. We recently extended the same support for iPhone 7 and iPhone 7 Plus in iOS 11.2.

Of course, when a chemically aged battery is replaced with a new one, iPhone performance returns to normal when operated in standard conditions.

防止意外關機

大約一年以前，在我們推送的 iOS 10.2.1 中包含了一項軟件更新，其目的是用來改進峯值負載下的電源管理，以避免 iPhone 6、iPhone 6 Plus、iPhone 6s、iPhone 6s Plus 和 iPhone SE 意外關機。在這一更新中，iOS 能夠在需要時對部分系統組件的最大性能進行靈活管理，以防止出現意外關機。這些變動通常察覺不到，但在某些情況下，用户可能會發現有些 app 的啟動時間變長了，有些性能表現變弱了。

用户對於 iOS 10.2.1 的反饋是正面的，因為它成功減少了意外關機的發生。隨着 iOS 11.2 更新的推出，我們還將這項支持擴展到了 iPhone 7 和 iPhone 7 Plus。

當然，如果用新的電池替換掉已經化學老化的電池，並在正常情況下使用，iPhone 就會恢復正常的性能表現。

Recent user feedback

Over the course of this fall, we began to receive feedback from some users who were seeing slower performance in certain situations. Based on our experience, we initially thought this was due to a combination of two factors: a normal, temporary performance impact when upgrading the operating system as iPhone installs new software and updates apps, and minor bugs in the initial release which have since been fixed.

We now believe that another contributor to these user experiences is the continued chemical aging of the batteries in older iPhone 6 and iPhone 6s devices, many of which are still running on their original batteries.

近期得到的用户反饋

今年秋天，我們開始收到一些用户的反饋，他們發現在某些特定情況下，iPhone 的性能變慢了。基於我們的經驗，我們最初認為是由這兩個因素的結合所導致：當操作系統升級時， iPhone 安裝了新的軟件、更新應用程序對性能造成的一個正常的臨時性影響，以及在系統更新的初始版本中已經修復的那些小錯誤。

我們現在認為，較早期的 iPhone 6 和 iPhone 6s 上電池的持續化學老化，是影響這些用户體驗的另一個因素，這些設備中有很多仍在使用最初的`那塊電池。

Addressing customer concerns

We’ve always wanted our customers to be able to use their iPhones as long as possible. We’re proud that Apple products are known for their durability, and for holding their value longer than our competitors’ devices.

To address our customers’ concerns, to recognize their loyalty and to regain the trust of anyone who may have doubted Apple’s intentions, we’ve decided to take the following steps:

Apple is reducing the price of an out-of-warranty iPhone battery replacement by $50 — from $79 to $29 — for anyone with an iPhone 6 or later whose battery needs to be replaced, starting in late January and available worldwide through December 2018. Details will be provided soon on .

Early in 2018, we will issue an iOS software update with new features that give users more visibility into the health of their iPhone’s battery, so they can see for themselves if its condition is affecting performance.

As always, our team is working on ways to make the user experience even better, including improving how we manage performance and avoid unexpected shutdowns as batteries age.

At Apple, our customers’ trust means everything to us. We will never stop working to earn and maintain it. We are able to do the work we love only because of your faith and support — and we will never forget that or take it for granted.

解決用户的擔憂

我們一直希望儘可能延長 iPhone 的使用壽命。Apple 的產品以經久耐用而著稱，它們能夠長時間保持原有價值，對此我們深感自豪。

為了解決用户的擔憂，對他們的信賴表示感激，並讓任何可能對 Apple 的出發點有過疑慮的人對我們重拾信心，我們決定採取以下措施：

Apple 將更換過了保修期電池的價格降低了 RMB 390 元，從 RMB 608 元降到 RMB 218 元。此舉針對使用 iPhone 6 及後續機型的需要更換電池的用户，在全球範圍內從 2018 年 1 月底持續到 12 月。詳細活動信息將於近期在 上公佈。

2018 年初，我們會發布一項 iOS 軟件更新，其中的新功能可讓用户更清楚地瞭解 iPhone 的電池健康狀況，用户可以親眼看到其狀況是否影響了性能。

我們的團隊正在一如既往地致力於讓用户體驗變得更好，這包括改進我們在性能管理和避免由於電池老化造成意外關機問題上的方式、方法。

對 Apple 來説，用户的信任意味着一切。我們將矢志不渝、努力贏得並呵護好這份信任。正是因為您的信念和支持，我們才能從事這份我們熱愛的工作。我們永遠不會忘記這一點，或認為這理所當然。
