Scientists have found a way to dual the battery life of smartphones

Perennial problem of modern mobile devices is the relatively short battery life. The reason for that the huge displays. And un-optimized operating system and continuous operation of cellular modules.

Scientists at the Massachusetts Institute of Technology (MIT) have developed a technology that will increase the battery life of smartphones twice. At the same time, battery performance will remain the same, and the changes will affect the energy consumption of the algorithm inside the phone, especially the amplifier signal.

As the researchers note, power radio consumes a significant amount of power even in standby mode, to always be ready to go into active mode. As a result, energy is wasted. In addition, the existing chips to 65% of the energy, is released as heat, which explains the increase in temperature the body when transferring large amounts of data (download a file, for example).

Some smartphones use up to five RF power amplifiers, but researchers suggest using one that can determine the amount of energy required to operate with a frequency of 20 million times a second.

Technology will begin to apply in 2013. According to a MIT, their decision will reduce the amount of energy consumed by 50%, significantly increasing the battery life of mobile devices from a single battery charge.

Apple is developing a new operating system, OS X 10.9

After almost half a year after the debut of OS X 10.8 Mountain Lion in the web there is evidence that Apple is developing the next version of the operating system for the Mac. According to C-news, online recorded at least 30 cars that are running the next generation desktop platform OS X 10.9.

Over the last few years Apple has moved to an annual renewal cycle OS X. The latest version - OS X 10.8 - was published in the shop Mac App Store in July of this year. Previous - OS X 10.7 Lion - launched in July 2011. Earlier update cycle was twice as long as: OS X 10.6 Snow Leopard was released in August 2009, and OS X 10.5 Leopard - in October 2007. Thus, a new version, under the alleged codename Lynx, expected in the summer of 2013.

Apple believes that the most promising variant of OS X is the convergence of desktop and mobile operating systems. In particular, the interest in this Federigo Craig, senior vice president of software development, and Bob Mansfield, who recently led a new direction for the development of semiconductors.

Apple has already started to integrate the functions of iOS in the desktop version of the operating system with OS X 10.7 Lion. Mountain Lion In this concept was further developed: The most recent operating system contains  the 10 most popular iOS features , including iCloud, messages, reminders, notes, Center notifications, Twitter, quick link, Game Center, AirPlay video replay function and voice input data.

In Apple intend to make the experience of interaction with any of the devices of the company was the same. For this reason, it is expected that in the years to OS X will be strongly modified. Update the team plans to move precisely this course.
