Battery Life Testing
Lenovo claims you should get up to 8 hours of usefulness from the IdeaPad Yoga 13's 3860mAh Li-Polymer 4 cell battery. To give you an idea of how long the IdeaPad Yoga 13 will last and to help you compare the IdeaPad Yoga 13's longevity to other systems, we ran two battery tests. For both tests, we set the screen's brightness to 50% and turned off all screen savers and sleep settings.
Keep in mind your usage patterns will significantly impact the IdeaPad Yoga 13's battery life. If you are watching videos, downloading files, or putting the ultrabook in sleep mode when the system is not in use, this will impact the time your system can run before needing to recharge.
Our web browsing test is the same one we run on tablets and smartphones. This test is designed to show how long a system can handle simple Web browsing. The test refreshes every three minutes and runs until the system shuts down because the battery is depleted. We also use Battery Eater Pro, which runs a heavy workload continuously to show you what the system can do when its CPU, GPU, memory, and storage drive are seeing heavy use. If you plan to use the ultrabook to work with multimedia (or even to do a lot of word processing) the results will give you a picture of what to expect.
