Lenovo Yoga 2 Pro Ultrabook Review
Battery Life
Battery life is a big deal with a mobile system, especially an ultrabook. Lenovo claims you should get up to 6 hours of battery life from the Yoga 2 Pro during FHD playback at 150 nits or up to 9 hours of battery life with Windows 8 in idle mode with the screen at 150 nits brightness.

In an attempt to quantitatively measure the Yoga 2 Pro's battery life in a controlled benchmark environment, we ran Battery Eater Pro. This test is designed to tax a laptop’s resources to give a feel for how long the laptop’s battery will last under heavy use. For the test, we set the Yoga 2 Pro's display to 50% brightness and enabled Wi-Fi.
Heavy-Duty Workload
In the Battery Eater Pro test, the Yoga 2 Pro lasted for two hours and 17 minutes. This may not seem like much, but remember this is a test that is designed to tax the ultrabook and mimic heavy use. In comparison to other systems, the Yoga 2 Pro earns fifth place in our comparison chart, which is above average for a machine of this type.
Battery Eater Pro is designed to show the worst-case scenario since the system is taxed during the test. In a real-world light usage situation with light web surfing, the battery gauge dropped from 100% to 90% in about 40 minutes. While running our web browsing battery test, the Yoga 2 Pro lasted about five hours and 50 minutes. Of course, battery life will vary considerably depending on what you demand of the system.
