Today published the results of a study conducted by experts from the Electric Power Research Institute (EPRI). This paper is concerned with power consumption of mobile devices Apple. It is alleged that the iPhone and iPad are spending when charging a small amount of energy.
Users of the iPhone 6 will be spent on charging only $ 0.47 per year, while iPhone owners 6 Plus - $ 0,52. For comparison, the cost of charging the iPhone 4 is estimated at only $ 0.38.
As for the tablets to Apple, charging iPad Air owners spend no more than $ 1.4 per year. In the case of the plates of the second and first generations, the figure is $ 0.83 and $ 0.82, respectively. Thus, the researchers note, the transition to post-PC era is accompanied by a general decrease in power consumption.
The study says that being in the socket, power adapters continue to draw power even if they are not connected iPhone or iPad. Thus, according to scientists, is wasted about two-thirds of the electricity used portable gadgets.
"If the billions of people who use mobile devices today adapatery disconnected from the network immediately after the end of charging, could annually save as much energy as they produce 2 medium power."
According to the study EPRI, economical electricity spend all residents of Germany, as well as the worst spenders in Europe are British.
