STRUGGLING to make your smartphone battery last the whole day? Paying for your apps might help. Up to 75 per cent of the energy used by free versions of Android apps is spent serving up ads or tracking and uploading user data: running just one app could drain your battery in around 90 minutes.

Abhinav Pathak, a computer scientist at Purdue University, Indiana, and colleagues made the discovery after developing software to analyse apps' energy usage. When they looked at popular apps such as Angry Birds, Free Chess and NYTimes they found that only 10 to 30 per cent of the energy was spent powering the app's core function.

For example, 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 user's location with GPS then downloading location-appropriate ads over a 3G connection. The 3G connection stays open for around 10 seconds, even if data transmission is complete, and this "tail energy" consumes another 28 per cent of the app's energy. Pathak blames the energy leakage on inefficiencies in the third-party code that developers use to generate profit on free apps. He will present the research at the EuroSys conference in Bern, Switzerland, next month.

i dont believe that for a second
they just want people to buy the apps

I doubt that, heard it from more than one source.... And the apps always ask for permissions for all kinda crap, I think if I remember correctly the paid apps ask for less, might be wrong

Anyway, getting up to 48hrs on my 9900 with the latest os, which has features that lick down processes that drain the battery and has battery saving mode

Lolz, these scientists no have nothing better to do with their time? Obviously some apps are better written than others, whether paid or free. Live wallpaper probably burn more battery than anything else on the phone.

No they dont. Some do, the poor written ones.

I have free apps and my phone is fine.

You are probably living on the phone why the battery is dieing so quickly.

2hrs to 71% is pretty normal on heavy use.
