Mystery Solved: Apple Admits it Slows Some Older iPhones
Many people have long believed Apple intentionally slows down performance of iPhones in an effort to get users to buy new ones.
For the first time, Apple has admitted to slowing some iPhones down. But the company explained it only took the action last year to prevent battery-related shutdowns.
Apple's action – and the company's decision to keep it secret - led to widespread criticism from industry analysts and iPhone owners.
Owners of iPhones in several states are suing Apple. They accuse Apple of violating fraud laws by purposely limiting performance without informing iPhone owners that the problems might have been fixed by replacing the device battery. This, they argue, forced them to spend more money to buy new iPhones.
The issue of iPhone slowdowns in certain phones was recently noted in an online post by the founder of software maker Primate Labs. In his post, John Poole cited test results suggesting repeated reductions in iPhone performance over time.
The tests included the iPhone 6s and iPhone 7, with several different operating system versions. Results of the tests blamed aging batteries for causing the reduced device performance.
Poole said his company's software that measures processor performance found that some users who replaced their iPhone batteries reported much improved results.
But he was not convinced that old batteries were the whole problem. He came up with a theory. He believed Apple must have made changes to the iOS software to limit iPhone performance when battery capacity reached a certain point.
A few days later, Apple released a statement admitting it made the software change. It said the action was needed to prevent certain devices from suddenly shutting down.
The problem, Apple said, was connected to lithium-ion batteries inside the iPhone. The batteries can fail in certain conditions – such as hot or cold - or as they age over time. This can sometimes cause older iPhones to shut down, Apple said.
Apple said it released the new feature last year for the iPhone 6, iPhone 6s and iPhone SE. It later added the iPhone 7 with iOS 11.2 and plans "to add support for other products" in the future.
"Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices," the Apple statement said.
But many iPhone owners were not very forgiving of Apple's decision, as evidenced on Twitter:
In his reporting of the latest developments, Wired magazine's Jordan McMahon pointed out several ways Apple could have handled the situation before deciding to secretly slow the phones.
He suggested Apple could have informed iPhone owners about the lithium-ion issues beforehand and given them a chance to get the batteries replaced. Or the company could have even launched a program to sell owners battery replacement kits.
Apple has always strongly resisted having owners buy and replace their own iPhone batteries. There are many companies that sell do-it-yourself kits or will do the service for you.
Apple has its own battery replacement service – either in Apple stores or through the mail - and charges $79 for any iPhone model that is no longer under warranty.
But based on the huge negative reaction to Apple's change, it seems many people are not aware of that possibility. They have complained about being forced to either buy a new, expensive iPhone, or switch brands to fix the problem.
Several economic analysts have lowered predictions for 2018 shipments of the iPhone X as some news reports also suggested there will be much lower demand. Taiwan's Economic Daily reported Monday that Apple could cut its sales targets for the iPhone X in the first quarter from 50 million to 30 million.

苹果公司首次承认拖慢了某些老款苹果手机的运行速度 。但是该公司称，去年才采取这一措施，目的是为了防止电池导致的意外关机 。
美国数个州的iPhone用户正起诉苹果公司 。他们指控苹果公司违反了欺诈法，故意限制iPhone手机性能却不告知用户可通过更换电池解决意外关机的问题 。他们认为，这迫使用户花更多钱购买iPhone新机 。
最近，软件制造商“灵长类实验室”创始人在网上发表了一篇文章，提到iPhone某些手机运行缓慢的问题 。约翰·普尔（John Poole）在文章中引用的测试结果表明，随着时间推移，iPhone手机的性能会不断下降 。
测试手机包括安装了不同版本操作系统的iPhone 6S和iPhone 7 。测试结果将设备性能下降归咎于电池老化 。
但是他不相信电池老化是问题的症结 。他提出了一项理论 。他认为苹果公司对iOS软件动了手脚，当电池容量达某一程度时会限制iPhone手机的性能 。
数日后，苹果公司发声明承认对软件做了变动 。该公司表示，此举是防止某些手机意外关机 。
苹果公司表示，该问题与iPhone内部的锂电池有关 。这种电池在遇热、遇冷和电池老化等情况下会意外关机 。苹果公司表示，这可能是导致部分老款iPhone关机的原因 。
苹果公司表示，去年为iPhone 6、iPhone 6S和iPhone SE手机发布了新功能，随后又在iOS 11.2系统中添加了iPhone 7 并计划未来增加对其它产品的支持 。
《连线杂志》的乔丹·麦克马洪（Jordan McMahon）在报道最新动态时指出，其实苹果公司私自拖慢手机运行速度前，可以采取其他方式来处理这一情况 。
他暗指，苹果公司可事先告知iPhone用户关于锂电池的问题，让他们自行更换电池 。或者推出一项企划，向用户出售电池更换套件 。
苹果公司一直强烈反对用户购买或更换iPhone电池 。有多家公司出售自助更换电池套件，或向用户提供更换电池服务 。
不过，从用户对苹果公司的巨大负面反响来看，似乎很多人没有意识到更换电池的可行办法 。他们抱怨称，要么被迫购买昂贵的iPhone新机，要么更换其它的手机品牌 。
经济分析师下调了对2018年iPhone X手机出货量的预测，一些新闻报道也暗示需求将会下降 。周一，中国台湾的《经济日报》报道称，苹果公司可能会将明年第一季度iPhone X的销售目标从5000万降至3000万 。
