As a quick check on multimedia performance, we decided to fire up a few HD video movie trailers to get a sense of how the Yoga 3 Pro handle the workload and also to get a look at how Intel's Core M CPU behaves when it's decoding from a Youtube stream or locally. Here's what things looked like when we fired up a 1080p Guardians of The Galaxy clip...
As you can see, Intel's Core M 5Y70 isn't scaling up to its top clock speed here and CPU utilization is hovering around a modest 16 percent. We've seen lower, frankly, from previous generation Intel HD integrated graphics but then again, there are probably a few driver tweaks and optimizations likely on tap in the coming weeks for Intel's Core M line.
There are some laptops currently available that can get through the day on a single charge, and many more that will give you several good hours of work before needing juice.
|Battery Eater Pro and Web Browsing Tests |
|Battery Life Testing |
We run two tests to give you a sense of how long the system will last
under light and heavy use. Our web browsing test is a light-use scenario
in which it refreshes a webpage over a WiFi connection until the
battery is exhausted. The Battery Eater Pro test gives the laptop a much
heavier workload to simulate the kind of stress you might put on the
machine with multiple resources engaged, including CPU, GPU, memory and
Sure enough, Intel's power-sipping Core M processor on board the Lenovo Yoga 3 Pro, affords the machine great battery life, whether under light-duty or heavy-duty use. In fact, this machine lasted the longest of any we've tested to date under either of the two test conditions. Dell's slightly emaciated Inspiron 11, with its 7 Watt Intel Pentium N processor, comes in a close second in the Battery Eater test. However, even a premium machine, like the Samsung ATIV Book 9 Plus, with its 4 cell battery and 3lb frame, versus the 3 cell battery and 2.6lb specs of the Yoga 3 Pro, gets edged-out by Lenovo's new thinness.
