Today smartphone is just like a handful personal computer in our palm. You can do almost everything like personal computer does. You can watch movie, listening to music, taking photos, recording video, browsing, gaming on smartphone. Someday with smartphone can do anything the same as personal computer does.
Those smartphone capabilities really need tough long life battery. As you can see that battery life has always been the one major concern to our favorite little Android smartphone companions. Every effort we do to make battery life longger like actively monitoring the energy use settings, killing each and every app that doesn't need to be running, etc. But it seems almost impossible to get more couple hours of battery life
A researcher at Purdue University may have found the main factor behind the smartphone energy goes and if he is right, then our penny pinching app purchases might just be killing our battery life.
Abhinav Pathak, a Purdue-based computer science researcher, claims 75% of the energy used by free apps is spent in downloading ads or uploading user data for advertising purposes while only 10%-30% was used for powering the apps core functionality. With today's power-hungry 3 and 4G devices, one app could drain your battery in a measly 90 minutes!
According to Mr. Pathak's research, the most playing apps, Angry Birds, only uses 20% of it's power consumption to run the display and a whopping 45% to locate a user and download those annoying pop-ups which always seem to drain the battery. Behind the apps process, the 3/4G connection stays active for another 10 seconds and accounts for 28% of all lost energy while playing Angry Birds.
Mr. Pathak suggests that inefficiencies in 3rd party code is to blame for the poor power consumption ratings of many free apps.
The solution, it would seem, would simply be to start paying for our apps and this might just be the impetus Android fans need to start rewarding developers for their hard work. For anyone interested in reading the full paper, follow the link: Fine Frained Energy Accounting on Smartphones
So if he is right the majority of Android user have to buy apps for saving their Android smartphone battery to minimize the apps downloading and uploading while running the apps. That would be mean a paid Android application surely will make your Android battery life running longer than before.
