报告:苹果iOS应用比安卓应用更爱抽风

Philip Elmer-DeWitt 2014年04月03日

苹果(Apple)公司内部流传着一个老笑话,那就是史蒂夫·乔布斯周围是一片“现实扭曲力场”:你离他太近的话,就会相信他所说的话。苹果的数百万用户中已经有不少成了该公司的“信徒”,而很多苹果投资者也赚得盆满钵满。不过,Elmer-DeWitt认为,在报道苹果公司时有点怀疑精神不是坏事。听他的应该没错。要知道,他自从1982年就开始报道苹果、观察史蒂夫·乔布斯经营该公司。
调研公司的数据显示,谷歌在“姜饼”之后推出的三个Android版本、奇巧、冰淇淋三明治以及果冻豆故障率大约仅为苹果最新版操作系统iOS 7.1的一半(约为0.7%)。同时,苹果iPad 和iPhone应用程序崩溃频率也要高于三星Android设备。

    从本文所附的图表中,《纽约时报》(New York Times)的昆汀•哈代硬是得出了他希望看到的结论,这也情有可原。

    在上周五的《纽约时报》上,哈代总结了一份关于移动应用程序崩溃率的新报告。他写道,在谷歌(Google)Android操作系统上运行的程序比在苹果(Apple)iOS上运行的应用程序更常出故障。

    哈代补充道:“iOS 7.1的故障率最低,很可能要部分归功于苹果严格控制进入苹果应用商店的应用程序。”

    上面可能是哈代期望看到的结论,但数据反映的情况却不是这样。

    哈代援引的这份报告名为《移动体验基准》(Mobile Experience Benchmark),上周四由总部位于旧金山的性能分析公司Crittercism发布。这家公司跟踪了10亿用户一个月的时间,每天监控30多亿次未指明的“事件”。

    它的研究结果表明,正如哈代所言,苹果最新版iOS,即iOS 7.1的应用程序故障率为1.6%,表现优于此前所有版本的iOS,也略优于Android 2.3版本“姜饼”(“姜饼”的应用程序故障率为1.7%)。

    但姜饼推出已经有四年时间了。谷歌之后推出的三个Android版本——奇巧(KitKat)、冰淇淋三明治(Ice Cream Sandwich)以及果冻豆(Jelly Bean)故障率大约仅为苹果最新版操作系统的一半(约为0.7%),比起iOS 7.0(故障率为2.1%)和iOS 6.0(故障率2.5%)就更不用说了。

    《移动体验基准》报告还指出,三星(Samsung)智能手机和平板电脑死机率在各平台上都比苹果iPhone和iPad低。但这一点在客户满意度的评级上还没有得到体现。根据市场咨询公司JD Power 去年10月发布的报告,在美国电话电报公司(AT&T)和威瑞森(Verizon)平台上iPhone得分较高,而三星设备在斯普林特(Sprint)和T-Mobile平台上得分较高。

    Crittercism的资金部分来自谷歌创投(Google Ventures),这一点可能会遭人非难。但这家公司两年前也曾发布过一份类似的报告,结论也与此类似,当时曾获得众多媒体报道,而苹果对此未置一词。如果它的研究方法存在致命缺陷,应该有人会发现。(财富中文网)

    Quentin Hardy may be forgiven for looking at the attached charts and seeing what he expected to see.

    Summarizing a new report on the failure rate of mobile apps, he wrote in Friday's New York Times that apps running on Google's (GOOG) Android operating system crash more frequently than apps running on Apple's (AAPL) iOS.

    "iOS 7.1 has the fewest crashes," he adds, "most likely thanks in part to the way Apple controls what apps go into its store."

    That may be what Hardy expected to see. But that's not what the data show.

    The report, Mobile Experience Benchmark, was issued Thursday by Crittercism, a San Francisco-based performance analytics firm that tracked a billion users for a month, monitoring more than 3 billion unspecified "events" per day.

    The results showed, as Hardy reported, that the newest version of Apple's iOS -- 7.1 -- had an app-crash frequency of 1.6%, better than any previous version of iOS and hair better than Android 2.3 "Gingerbread" (1.7%).

    But Gingerbread is more than four years old. Newer Android releases -- KitKat, Ice Cream Sandwich and Jelly Bean -- crash roughly half as frequently (0.7%) as Apple's newest version. They are even more stable than iOS 7.0 (2.1%) and iOS 6.0 (2.5%).

    The report also found that Samsung's smartphones and tablets crash less frequently than Apple's iPhones and iPads, right across the board. That's not yet reflected in the customer satisfaction ratings. In J.D. Power's Oct. 2013 report, iPhones scored better at AT&T (T) and Verizon (VZ), and Samsung's devices did better at Sprint (S) and T-Mobile (TMUS).

    Crittercism's start-up was funded in part by Google Ventures, which might raise some eyebrows. But it issued a similar report two years ago with similar findings that got a lot of press and no comment from Apple. If there was a fatal flaw in the methodology, nobody seems to have found it.
