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

你并不是一個(gè)人在戰(zhàn)斗。谷歌趨勢（谷歌推出的一項(xiàng)新的搜索產(chǎn)品）顯示人們的搜索內(nèi)容，即當(dāng)蘋果發(fā)布它的最新iphone的那一瞬間，iphone的運(yùn)營速度就變慢了。這顯示出人們認(rèn)為他們的舊的iphone產(chǎn)品速度突然的下降。

哈佛經(jīng)濟(jì)學(xué)教授Sendhil Mullainathan在紐約時(shí)報(bào)上顯示了谷歌趨勢的數(shù)據(jù)，假設(shè)這可能是一個(gè)故意的，事先計(jì)劃好的行動(dòng)，更好地鼓動(dòng)人們?nèi)ベI新的iphone.

上面提到的推測對于任何制造復(fù)雜電子產(chǎn)品和軟件的任何公司是有可能的—在20世紀(jì)20年代至30年代之間的太陽神計(jì)畫（Phoebus Cartel）被證實(shí)是公司故意減產(chǎn)他們的產(chǎn)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(tǒng)讓一切都變慢了

智能手機(jī)和平板電腦遇到的問題和臺(tái)式機(jī)和平板電腦的是一樣的。運(yùn)營的時(shí)間越長，軟件攜帶的數(shù)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(huì)更快地造成這些問題。不必要地占用電子產(chǎn)品的處理器，同時(shí)會(huì)使其他的必要的功能降低速率。

與此同時(shí)，當(dāng)系統(tǒng)和技術(shù)提高并且容許發(fā)展越來越多的解決方案時(shí)，軟件對于電子產(chǎn)品的處理硬件的要求也隨之增加。

以Facebook應(yīng)用程序?yàn)槔F(xiàn)在對硬件的要求比起剛開始發(fā)布的時(shí)候要求越來越多，同樣也適用于Twitter 應(yīng)用程序，safari瀏覽器，郵件中。

應(yīng)用程序的更新

    當(dāng)應(yīng)用程序更新后做新的事情的時(shí)候，他們在老的硬件設(shè)施上運(yùn)行會(huì)變慢。可能這種情況一開始不會(huì)被發(fā)現(xiàn)直到有人指出為止。當(dāng)人們得知新的手機(jī)發(fā)布的時(shí)候，這等于就提醒人們他們的手機(jī)已經(jīng)老化，使得人們對于之前他們忽視的手機(jī)的落后問題更加的敏感。

當(dāng)一個(gè)更快的，更強(qiáng)有力的模型發(fā)布的時(shí)候，在汽車上也出現(xiàn)了相似的問題。老一點(diǎn)的汽車（雖然也很光鮮亮麗）看起來似乎就有點(diǎn)舊了，速度似乎也有底慢了。

但是蘋果手機(jī)或多或少的獨(dú)特之處就在于在一段時(shí)期內(nèi)，蘋果手機(jī)新推出的ios 軟件在舊的手機(jī)里仍可使用。

軟件的更新

當(dāng)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(dāng)新的軟件發(fā)布的時(shí)候，成千上萬的蘋果電腦使用者就會(huì)立即更新他們手機(jī)上的軟件，特別的突出小的和細(xì)微的差別。蘋果用戶激動(dòng)萬分地更新他們的智能手機(jī)，并且集中精力注視著每一個(gè)方面，這樣常常會(huì)使一些人發(fā)出疑問：“它的速度是否變慢了？”

當(dāng)蘋果公司發(fā)布一部新手機(jī)的時(shí)候，你是否感覺到手機(jī)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?
