Your Android phone’s battery is getting sucked dry by advertisements in free apps, a new study suggests. According to a team lead by Abhinav Pathak at Purdue University, up to 75 percent of the energy used in freemium apps is supposedly spent serving up ads or tracking/uploading user data.
By using a proprietary tool called EProf, the team was able analyze an app’s energy usage and found that a game such as Angry Birds only uses 10 to 30 percent of its energy for the app’s core function. The other percentage is consumed by uploading user information metrics, location and downloading/displaying location-appropriate ads. “The 3G connection stays open for around 10 seconds, even if data transmission is complete, and this “tail energy” consumes another 28 percent of the app’s energy,” NewScientist said.
The study ultimately found that the apps Pathak’s team tested were poorly coded. As a result, Pathak has plans to release the EProf tool for free under an open-source license without, one would assume, any trace of ads. In the future, hopefully findings like this can encourage more efficiently coded apps and put less strain on a smartphone’s battery.
