就在發布最新的蘋果智能機的那一瞬間，你是否感覺到你的手機速度似乎變慢了些呢？

你并不是一個人在戰斗。谷歌趨勢（谷歌推出的一項新的搜索產品）顯示人們的搜索內容，即當蘋果發布它的最新iphone的那一瞬間，iphone的運營速度就變慢了。這顯示出人們認為他們的舊的iphone產品速度突然的下降。

哈佛經濟學教授Sendhil Mullainathan在紐約時報上顯示了谷歌趨勢的數據，假設這可能是一個故意的，事先計劃好的行動，更好地鼓動人們去買新的iphone.

上面提到的推測對于任何制造復雜電子產品和軟件的任何公司是有可能的—在20世紀20年代至30年代之間的太陽神計畫（Phoebus Cartel）被證實是公司故意減產他們的產品從而使顧客買的更多--- 但是這種情況在今天的iphone事件是不可能的

      浮腫的系統讓一切都變慢了

智能手機和平板電腦遇到的問題和臺式機和平板電腦的是一樣的。運營的時間越長，軟件攜帶的數字碎片和碎屑就越多。殘留的文件，壞掉的鏈接，相互沖突的軟件都會更快地造成這些問題。不必要地占用電子產品的處理器，同時會使其他的必要的功能降低速率。

與此同時，當系統和技術提高并且容許發展越來越多的解決方案時，軟件對于電子產品的處理硬件的要求也隨之增加。

以Facebook應用程序為例，現在對硬件的要求比起剛開始發布的時候要求越來越多，同樣也適用于Twitter 應用程序，safari瀏覽器，郵件中。

應用程序的更新

    當應用程序更新后做新的事情的時候，他們在老的硬件設施上運行會變慢。可能這種情況一開始不會被發現直到有人指出為止。當人們得知新的手機發布的時候，這等于就提醒人們他們的手機已經老化，使得人們對于之前他們忽視的手機的落后問題更加的敏感。

當一個更快的，更強有力的模型發布的時候，在汽車上也出現了相似的問題。老一點的汽車（雖然也很光鮮亮麗）看起來似乎就有點舊了，速度似乎也有底慢了。

但是蘋果手機或多或少的獨特之處就在于在一段時期內，蘋果手機新推出的ios 軟件在舊的手機里仍可使用。

軟件的更新

當軟件提高和增添更多功能后，它對硬件的要求也就隨之提高了，并且使舊的軟件看起來似乎更慢。

當新的軟件發布的時候，成千上萬的蘋果電腦使用者就會立即更新他們手機上的軟件，特別的突出小的和細微的差別。蘋果用戶激動萬分地更新他們的智能手機，并且集中精力注視著每一個方面，這樣常常會使一些人發出疑問：“它的速度是否變慢了？”

當蘋果公司發布一部新手機的時候，你是否感覺到手機速度變慢了呢？

 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?
