Free apps might  kill battery life of phone

According to Abhinav Pathak, a computer scientist at Purdue University, Indiana, and colleagues, running only one Android app could eat up your battery in nearly 90 minutes.

The researchers came up with the finding after developing software to analyse appsтАЩ energy usage.

When they assessed popular apps like Angry Birds, Free Chess and NYTimes they discovered that just 10 to 30 per cent of the energy was used powering the appтАЩs core function.

For instance, in Angry Birds only 20 per cent is used to display and run the game, while 45 per cent is spent finding and uploading the userтАЩs location with GPS then downloading location-appropriate ads over a 3G connection, the New Scientist reported.

The 3G connection stays active for about 10 seconds, even if data transmission is complete, and this тАШtail energyтАЩ drains additional 28 per cent of the appтАЩs energy.

Pathak insists the energy leakage on inefficiencies in the third-party code that developers use to generate profit on free apps is responsible for the superfluous battery consumption.
