The study said Android application power consumption 70% from the built-in advertising

Purdue University and Microsoft joint implementation of a study show that the Android smartphone includes advertising services application, the power consumption of a single ad services may account for up to 70 of the total electricity consumption of the application%.

Purdue University and Microsoft's research team used a the named EProf energy consumption monitoring tool, the HTC Passion mobile phone powered by Android 2.3, tested five popular Android applications: "angry bird" (Angry Birds), a free version of chess (free chess), the Android browser, the web map service (MapQuest) and "New York Times application. The results are eye-opener.

When researchers in the play "angry bird" game HTC Passion cell phone, the phone 70% of electricity consumption due to the game in the background to upload user data (eg location information) to download ads and displayed to the user to watch . The free version of chess also shows a similar energy consumption, but this time only the advertising services an outlay of 70% of electricity.

The research team claims that the excessive power consumption due to poor advertising module due to programming, they want developers and advertisers to write more efficient advertising program.

However, advertising is not the only power-hungry things. Android browser and the application of the New York Times, only to track user information function of a consumption of about 15% of the battery. EProf tools also found applications - such as the Android version of the Facebook application - defects also make the battery too quickly run out of power, because such defects cause the CPU can not enter sleep mode after the application is closed.

The research team also plans in the near future the EProf tools into an open-source software.
