The Yoga 11s moves away from the NVidia Tegra 3 chipset found in the original Yoga 11, instead offering 1.5 GHz Intel Core i5-3339Y processor. The third generation Intel processor provides a nice bump in terms of performance, but the Yoga 11S still offers sub-par performance compared to other competitors at the $1000 price point.

Combined with 8GB of RAM and 256GB SSD the Yoga 11S will be able to tackle normal word and web functions with relative ease. More demanding tasks like streaming video or running complicated Office Excel functions shouldn’t be too much of a problem for the device either. With 8GB of RAM the device is able to juggle various tasks without any noticeable drops in performance. Graphically intensive functions prove to be far more challenging for the device with its Intel HD 4000 Graphics. With the lack of a dedicated GPU the Yoga 11 is capable of tackling less taxing video games, but the device won’t be able to play newer games or handle high definition video editing.

The 256GB SSD provides fast boot up and restore times, perfect for users on the go. Data load speeds weren’t as fast as expected, but they were still more than serviceable. The Lenovo Yoga 11S certainly isn’t a slouch in terms of performance; but the offering pales in comparison to other devices like the Sony Vaio Pro 11 or the 11-inch Apple MacBook Air.

Our review unit of the Lenovo IdeaPad Yoga 11S includes the following specifications:

  • Windows 8 (64-bit)
  • 1.5 GHz Intel Core i5-3339Y Processor
  • 11.6″ HD IPS Display (1366 x 768) 10-Point LED multi-touch 300 nits
  • 8GB DDR3
  • 256GB m-SATA II SSD
  • Bluetooth 4.0
  • 802.11 b/g/n
  • 4-cell 42WH Lithium Polymer battery
  • Dimensions: 11.73″x 8.03″ x 0.67″
  • Weight: 3.08lbs.
  • Starting Price: $750
  • Price as configured: $1000


The unit that NBR reviewed was a mid-tier configuration offering an 1.5 GHz i5-3339Y processor, 8GB of RAM and a 256GB SSD for $1000. The base model featured a 1.4 GHz i3-3229Y processor, 4GB of RAM and a 128GB SSD for $750.

Lenovo also offers a high-end model complete with a 1.5GHz i7-3689Y processor, 8GB of RAM, a 256GB SSD and a bright clementine-orange lid for $1,300.

Crystal DiskMark storage drive performance test:

Heat and Noise

The vent is located along the back-end of the chassis below the display. The location of the vent is ideal as it makes sure to push the heat away from the user. The fan is relatively quiet in most instances, only producing a faint hum when the device is pushed to capacity.

The device does have a propensity for heating up rather quickly. Activities like streaming video or attempting to play low-end games will cause the device to increase in temperature in only a few minutes. The device will heat up to the point where it is certainly noticeable and at times can be a bit uncomfortable, though it never reaches temperatures that would prevent it from being used as a laptop.

Battery Life

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):

In our test the Lenovo IdeaPad Yoga 11S ran for 3 hours and 32 minutes before shutting down after reaching the 5 percent battery reserve limit. Running at just a tad over three and a half hours the Yoga 11S offers sub-par battery life, especially when compared to other convertible notebooks. Users simply using basic word and productivity functions will be able to edge out a bit more battery life as the device ran for 4 hours and 50 minutes in the PowerMark productivity test. However, users can also expect substantially less battery life while viewing media, as the Yoga 11S only ran for 2 hours and 37 minutes in the PowerMark entertainment test.

This is where the lack of a fourth-generation Haswell CPU is really noticeable. Considering that other notebooks on the market are starting to employ the new chipset at competitive price points, the sub-par battery life is tough to concede on.

    Very clever, convenient little notebook. But, after a few weeks and updates, it turns into the usual infuriating, sludge-filled, Windows fuelled hopeless wreck. It goes slower and slower, and for instance, it refuses to accept that it’s connected to the internet, although the “charms” say it is. I’ve had to reset it twice. Lenovo support is also hopeless. Search for help and you just end up reading conversations between bad-tempered wiseacres who know little but say a lot. All computers seem to be like this, hence all the rip-off cleaning programs and work-rounds etc. We don’t accept that sort of performance from cars. I loved it for the first three weeks, then the illusion faded. I wish I’d bought a Mac!
