When Jobs announced the Macbook Air, many people praised Apple's industrial design, but at the same time questioned the battery life of the Macbook Air. According to Jobs' announcement, the Macbook Air could last up to 5 hours, which drew a lot of opposing opinions—such a slim body simply didn't have the space for a large-capacity battery. Many believed that the Macbook Air’s battery life would be no more than 2.5 hours, and some even thought Jobs was deceiving consumers. As a result, foreign websites conducted real tests on the battery life of the Macbook Air to see if it was truly as impressive as claimed or if Jobs was lying. Below are the test results.
