One of the thorniest subjects when the topic is smartphones, regardless of operational system running on them, the life of the drums. Carrying it almost every day has become the habit of many of us. And for others it is no longer surprising to have to go without a phone for a few hours precisely because the handset battery decides to die sooner than expected. Solutions? Yes that h. Among them, the manufacturers suggest that the user has two batteries always on hand. Other companies even come up with ways to attach a second battery to the smartphone, which makes it a little monster. Not to mention that there are apps whose main function is to manage the energy consumption of the phone and thus give longer battery life. But why are such apps mostly paid? Why there is no free apps for this purpose?
Generally, free apps come with advertising banners, which are responsible for 75% of their total energy expenditure. Yes, every time new advertising data appears on your smartphone screen from a certain app, keep in mind that a lot of your battery power is being used up. Some free apps have the power to drain a battery with your ad in just 90 minutes if they're running nonstop. That advertising apps used up the battery in us was a big surprise. Surprising even the amount of expense they represent.
The discovery of a computer group from Purdue University, Indiana, which developed software that determines application energy expenditure. The software eventually accused unpaid versions of apps like Angry Birds or NYTimes as much as spending between 10% and 30% of energy on their core function.
Let's just look at the data for the angry Birds: While the free app only uses 20% energy to make the game work and display, 45% of the energy is spent for the app to determine the location of the user via GPS and, with that information, send it to the user via 3G connection, advertising linked to your location. This process consumes 10 seconds of the 3G connection, regardless of the time taken to complete the transfer of advertising data. This overuse alone represents 28% of Angry Birds total performance.
Of course, the most immediate solution for wasting battery power of your smartphone, while more efficient technologies are not developed, avoid using free apps. Maybe investing in good paid apps is not that bad.
