Apple today introduced not only a new MacBook Air, but also the computer with the longest battery life in its history. Thanks to its 50,3 watt-hour battery, the new product can last up to 12 hours of web browsing, 13 hours of iTunes video playback and 30 days in standby mode. These impressive figures cannot be surpassed by any computer from the company, not only currently offered, but also historically. Apple. Currently available computers Macbook Pro it offers "only" 10 hours of movie playback in iTunes and you can browse the internet for the same amount of time. Classic MacBook then it can play movies for 12 hours and you can browse the web for 10 hours.

Apple understandably uses standardized tests for all its computers and, for example, internet surfing time is measured in such a way that MacBook prowatches 25 popular websites with brightness set to 75% maxima or if you want, how Apple shows with the brightness set to 12 button clicks from zero. The iTunes movie playback test then measures by playing content in Full HD resolution, i.e. 1080p, while setting the display to 75% brightness again. Standby mode is then measured by the computer being connected to the internet via Wi-Fi, logged in to iCloud and has applications running before entering standby mode Safari and Mail.

What is interesting above all is how he did it Apple achieve this battery life. This is a combination of a tuned operating system, new hardware and a relatively high battery capacity. It is clear that, just like with MacBookfor the duration of video playback differs from the duration of web browsing, while in the case of MacBookFor the Pro, this figure is the same and you can watch both the web and movies for 10 hours. Applu has therefore managed to optimize consumption for different activities separately and it can be seen that MacBook Pro consumes the same amount of energy for both activities.
