Having a long battery life is one of the qualities of a good Mac. More power means that more tasks can be completed. According to Apple’s website, a new MacBook can last up to 10 hours of web browsing, iTunes movies playback, and other light tasks. A single charge can even last up to 30 days of standby time. But these estimates differ greatly from the actual performance because different tasks consume different amounts of battery life.
