If having a long-lasting battery is your most important consideration when buying a laptop, then you really don’t have much of an option besides the MacBook Pro. Which?, a renowned consumer product testing publication based in the United Kingdom, last week published the results of its most recent laptop battery life tests and found that the 13-inch Retina-equipped MacBook Pro bested rival offerings that ran on both Windows 8 and Google’s (GOOG) Chrome OS. Overall, Which? found that Apple’s (AAPL) newest 13-inch laptop delivered 388 minutes of web browsing time, or 30 minutes longer than the second-best laptop, the Windows 8-based Acer (2353) Aspire M5-581T. Other laptops studied fared significantly worse, such as the Samsung (005930) Series 3 Chromebook, which delivered 224 minutes of web browsing, and the Windows 8-based Advent Monza T 200, which delivered just 125 minutes of web browsing time.
