“In the Which? test lab we test every laptop for battery life, by browsing the web and also watching movies from its hard disk, so you can buy the best portable laptop,” Katie Waller reports for Which? Tech Daily.

“We compared the first 18 Windows 8 laptops tested in our lab with Apple’s 13-inch Macbook Pro with Retina Display and the Samsung Series 3 Chromebook to see which gives you the best internet battery life,” Waller reports. “The longest running Windows 8 laptop for web browsing is the Acer Aspire timeline Ultra M5-581T – a 15.6″ screen, 2.1kg ultrabook. It lasted almost six hours on battery – enough to get you to from London to Middlesbrough and back – and fell 30 minutes shy of the battery life of the 13″ Apple Macbook Pro Retina.”
