According to a recent report by Abhinav Pathak, a computer scientist at the Purdue University in Indiana, one of the cause of battery drain on smartphones may be down to free applications that have adverts.
The team at the university have been testing out free applications that come with adverts and have discovered that around 10 to 30 percent of the energy used by the application was spent powering the applications core functions.
The remaining amount of power spent was actually used to deliver adverts to the application, and a number of different applications were tested on Google’s Android platform.
The researchers determined that in some applications up to 75 percent of the actual powered used by the application was used for serving adverts and tracking and uploading user data.
