Equipped with a 1.6GHz Intel Core i5-4200U CPU, 4GB of RAM, Intel HD Graphics 4400 and a 128GB SSD the Yoga S1 offers solid performance in line with other high-end Lenovo devices such as the IdeaPad Yoga 2 Pro and ThinkPad T440s. Users willing to take a hit in performance can opt for the base model which comes equipped with an Intel Core i3-4010U CPU and a standard 1366 x 768 touch display for $1,050.
With its solid array of specs normal word and web functions prove to be little challenge for the Lenovo ThinkPad Yoga S1. The device is also capable of handling more complicated Microsoft Office functions such as computing complicated Excel spreadsheets. Juggling multiple programs also doesn’t prove to be a challenge for the device, as NBR was able to run a handful of applications along with 10 open web-tabs without any noticeable drop in performance.
Without a dedicated GPU, graphics performance is somewhat limited. The Yoga S1 cannot handle high-end demanding game titles and is not capable of editing 3D video. However, the notebook is capable of editing HD videos and play select titles at lowered graphical settings such as Left for Dead.
While the 128GB SSD does not afford the Yoga S1 a great deal of storage it does offer lighting fast speeds. Files and applications open almost instantly and the notebook was able boot to the Windows 8.1 start screen at an average of about 10 seconds.

Heat and Noise
The notebook’s main series of vents rest along the back end of chassis between the two displays hinges. Resting along the backside of the device, the hot air emanating from the device is pushed away from the user. However, as a petite ultrabook, the notebook doesn’t really produce a great deal of heat to begin with. Even when taxed the notebook remains relatively cool and can be comfortably used as a laptop. The Yoga S1 also runs quietly for the most part. Under normal circumstances the notebook is near silent. However, when the device is taxed it will produce a faint and steady hum.
To test battery life, we used our new PowerMark benchmark in balanced mode. The test consists of a combination of automated web browsing, word processing, gaming and video playback workloads. The test is far more strenuous than our previous test, measuring the machine under a litany of scenarios to better simulate real life use. With the test being far more demanding the scores are understandably lower than our previous benchmark.
PowerMark “Balanced” battery life test results (higher scores mean better life):
The Lenovo ThinkPad Yoga S1’s built-in 47Wh battery ran for 4 hours and 15 minutes at 110 nits before shutting down. Running well over four hours the Yoga S1 offers solid battery life. Considering that our tests are more demanding than normal conditions, the notebook should last an entire day on a single charge.
