就在发布最新的苹果智能机的那一瞬间，你是否感觉到你的手机速度似乎变慢了些呢？
你并不是一个人在战斗。谷歌趋势（谷歌推出的一项新的搜索产品）显示人们的搜索内容，即当苹果发布它的最新iphone的那一瞬间，iphone的运营速度就变慢了。这显示出人们认为他们的旧的iphone产品速度突然的下降。
哈佛经济学教授Sendhil Mullainathan在纽约时报上显示了谷歌趋势的数据，假设这可能是一个故意的，事先计划好的行动，更好地鼓动人们去买新的iphone.
上面提到的推测对于任何制造复杂电子产品和软件的任何公司是有可能的—在20世纪20年代至30年代之间的太阳神计画（Phoebus Cartel）被证实是公司故意减产他们的产品从而使顾客买的更多--- 但是这种情况在今天的iphone事件是不可能的
浮肿的系统让一切都变慢了
智能手机和平板电脑遇到的问题和台式机和平板电脑的是一样的。运营的时间越长，软件携带的数字碎片和碎屑就越多。残留的文件，坏掉的链接，相互冲突的软件都会更快地造成这些问题。不必要地占用电子产品的处理器，同时会使其他的必要的功能降低速率。
与此同时，当系统和技术提高并且容许发展越来越多的解决方案时，软件对于电子产品的处理硬件的要求也随之增加。
以Facebook应用程序为例，现在对硬件的要求比起刚开始发布的时候要求越来越多，同样也适用于Twitter 应用程序，safari浏览器，邮件中。
应用程序的更新
当应用程序更新后做新的事情的时候，他们在老的硬件设施上运行会变慢。可能这种情况一开始不会被发现直到有人指出为止。当人们得知新的手机发布的时候，这等于就提醒人们他们的手机已经老化，使得人们对于之前他们忽视的手机的落后问题更加的敏感。
当一个更快的，更强有力的模型发布的时候，在汽车上也出现了相似的问题。老一点的汽车（虽然也很光鲜亮丽）看起来似乎就有点旧了，速度似乎也有底慢了。
但是苹果手机或多或少的独特之处就在于在一段时期内，苹果手机新推出的ios 软件在旧的手机里仍可使用。
软件的更新
当软件提高和增添更多功能后，它对硬件的要求也就随之提高了，并且使旧的软件看起来似乎更慢。
当新的软件发布的时候，成千上万的苹果电脑使用者就会立即更新他们手机上的软件，特别的突出小的和细微的差别。苹果用户激动万分地更新他们的智能手机，并且集中精力注视着每一个方面，这样常常会使一些人发出疑问：“它的速度是否变慢了？”
当苹果公司发布一部新手机的时候，你是否感觉到手机速度变慢了呢？
Does your iPhone feel like it gets slower the moment the latest Apple smartphone gets released?
You’re not alone. Google Trends shows a spike in searches from people simply for “iPhone slow” the moment Apple releases its latest iPhone, showing that people perceive their older iPhones to suddenly slow down.
The Havard economics professor Sendhil Mullainathan presented Google Trends data on the New York Times to posit that this could be a deliberate, preprogrammed action, to spur people to buy new iPhones.
While that is possible by any company who makes complex electronics and software – the Phoebus cartel of the 1920s and 1930s proved companies were willing to intentionally hobble their products to get consumers to buy more – it is highly unlikely in this case.
Bloated systems slow everything down
Smartphones and tablets suffer from similar issues to desktop and laptop computers. The longer they run, the more digital debris and detritus their software collects. Left over files, broken interlinks and conflicting software can quickly cause issues, tying up the device’s processor unnecessarily and making other necessary functions slow down.
Meanwhile the demands made of the processing hardware of devices by software ever increases as the systems and techniques improve and allow more and more powerful solutions to be developed.
The Facebook app for instance, does far more and requires far more of the hardware now than when it was first released, as does the Twitter app, Safari, Mail, and even the Guardian’s own app.
App updates
As apps get updated to do new things they can become slower on older hardware, but it might go unnoticed at first, until someone points it out. Hearing about a new smartphone release reminds the user that their phone is older, making them more sensitive to the lag and stutter they might previously have ignored.
A similar thing happens with cars when a faster, more powerful model is released, making an older (though still shiny) car seem a little less new and seem a little less quick off the mark.
But wher Apple’s iPhone is more or less unique is that the release of a new iPhone also brings a new version of Apple’s iOS software for older iPhones, typically within days.
Software updates
As the software improves and adds more features it demands more of the hardware, and could make older models feel slower than they previously were.
Millions of iPhone users promptly upgrade to the latest software when it is released, instantly highlighting small and subtle changes. Users excitedly updat their smartphones and pore over every little aspect, causing many to wonder, "does it feel slower?".
Do you feel like your iPhone suddenly gets slower as Apple releases a new phone?
