The free application will reduce the battery life is very much

The free application is a very good option when the user wants to save a few coins in exchange for the feature match, but a new study has suggested that they may cause you to charge your battery than applications using paid.
 
The charging many times of course also cause long-term effects of battery life, so free is not really saved.
 

 
The Microsoft Research and University Purdure have used a power tool reviews to find the special effects of the application for Android and Windows Phone battery life when operating on a 3G connection. Specifically, 75% of energy requirements is not an application for the operation of features, but for the display and operation of third-party ads - almost always appears in the free application .
 
In this study, the team has used six popular smartphone applications - including Angry Birds, Facebook, and find out how they work on three of the HTC Magic smartphone, Android Passion and TyTN II running Windows Mobile. Apple's iPhone can not be tested by the application of extrinsic limitations built into the operating system IOS.
 
Rovio fans may be surprised to learn that, in the free version, only 20% of energy consumption is used to operate the gameplay, 45% is used to determine the location of the player to navigate ad display appropriate ads.
 
The study also discovered what they called a "tail 3G", where battery power is decreased even if the machine has done a specific action, such as the download is complete information . With Angry Birds, they point out that "tail 3G" has more than 25% of total energy consumption of the game.
 
However, the phone battery is not necessarily so under pressure. By restructuring the source code in some applications, the researchers were able to reduce total energy consumption 20-65%.
 
Of course, it is annoying when you unplug the charger and battery bar to see the day come quickly, even worse, no applications will effectively reduce the lifespan of the battery faster than necessary. Perhaps a paid version would be an attractive option after all these things.
