移动分析公司Zokem日前公布了一项调查结果，表明智能手机用户白天使用最频繁的是短信、通话等手机功能，但夜间使用频繁大为上升的服务却是手机网页、应用。

据游戏邦了解，这个结果采自Zokem对1万名智能手机用户的调查，以及2009至2010年对16个国家的智能手机应用进行了650万次的追踪访问。

如以下曲线图所示，在一天工作结束之后，手机语音功能的使用率急速下降，远低于短信功能，可见对大多数用户来讲，手机并非沟通的桥梁，而是一种商务用途的通讯工具。

可能早就有人预测到了这种结果，但这个发现对那些手机广告商来说仍然很重要，因为它可以指出哪些时段投放广告才能让利润最大化。

Mobile Web, Native App Use Increases at Night

It’s none-too-shocking news, but well worth noting: a new study of over 10,000 smartphone users has indicated that mobile Web and mobile application usage increases during the evening and nighttime hours. Meanwhile, more traditional types of communications attract increased attention during the day.

The data comes from mobile analytics firm Zokem, which found that voice and messaging dominate in the day time, but apps, and to a lesser extent, mobile Web browsing really take off after the workday is over.

The results of the study, seen here in the charts below, show the usage patterns among smartphone owners during a typical working day.

Voice drops quicker than messaging, says Zokem, because it’s a more business-oriented service. (So true! No one actually calls each other anymore, do they?)

While this data may just serve to reconfirm suspicions you already had, it’s important information for mobile advertisers, as it indicates the most important, and therefore, the most lucrative, times of day to target ads.

For what it’s worth, the data represented here comes from a fairly good-sized dataset: over 10,000 smartphone users, including 6.5 million distinct smartphone application usage sessions in 16 countries during 2009 and 2010.（source:readwriteweb）
