The Lenovo Yoga 900 – A Review

Introduction

Beginning in January 2008, Lenovo has introduced a range of consumer-oriented computers named IdeaPad. The range has a number of different series within it, each designed for a different purpose or user group. The Yoga series is a line of tablets and laptops. The name “Yoga” was chosen because the laptops have hinges that allow the screen to be fully folded back (up to 360°) to convert a laptop into a tablet. A Yoga laptop can also be placed in “tent” or “stand” mode for showing presentations or movies.

The latest generation is the Yoga 900, introduced in October 2015. It is clearly the successor to the Yoga 3 Pro, which was introduced in October 2014. The Yoga 900 has almost exactly the same dimensions and design as the Yoga 3 Pro, including the unique Lenovo “watchband” hinge. For that reason, I’ve used the Yoga 3 Pro as the basis for comparison with the new Yoga 900 in this review. Compared to the Yoga 3 Pro, Lenovo has also made changes in the Yoga 900 design, both internally and externally, which I will point out in this review.

I’ve been able to do this review because Lenovo has provided me with an example of the Yoga 900 in mid-September, ahead of the official launch on October 19, 2015. I’ve spent the past couple of weeks using it, and comparing it with a Yoga 3 Pro that I’ve had since January 2015.

This post focuses on the Yoga 900 hardware and its performance. I have a separate post looking at the software environment of the Yoga 900, i.e. the setting up of Windows 10, and a look at the software bundled with the Yoga 900 by Lenovo. 

Here’s a table that shows a quick comparison between the Yoga 3 Pro and the new Yoga 900:

*There is an i7-6500U, 8GB and 256GB SSD fitted on the Yoga 900 I have, and it is running Windows 10 Pro.

Both the Yoga 900 and the Yoga 3 Pro are examples of what Intel calls the Ultrabook class of laptop. That is, they are ultrathin, using solid-state drives, low-power Intel Core processors, and (because of their thinness) do not have optical disc drives or full-size Ethernet ports. They are the Windows equivalent of Apple’s Macbook Air series.

Unboxing

On September 17, UPS delivered a rather plain box: white (on top) and orange (underneath), with four icons on the side representing the four Yoga configurations (Laptop, Stand, Tent, and Tablet).

clip_image002

clip_image004

Like the box of the Yoga 3 Pro, it contains a slick piece of paper engineering – after taking off the lid, you fold back the two flaps covering the top, and as you do so, the Yoga 900 rises out of the box to greet you. This is a nice touch to the packaging.

clip_image002[4]

clip_image004[4]

Underneath the Yoga 900 are compartments that hold the power adaptor, the special USB power cable, and a sleeve containing the quickstart user guide. In my example, the guide was missing, it may have still been in preparation. However, I didn’t really need it, since I’ve been here before, so I could get straight on with plugging in the adaptor and cable and setting up Windows 10 on the machine (see my separate post).

clip_image006

Before doing that, I thought it would be useful to compare the Yoga 900 side-by-side with the Yoga 3 Pro, so here are some photos of the two machines together. The Yoga 900 came in the Champagne Gold colour, while the Yoga 3 Pro is Clementine Orange.

clip_image008

Yoga 900 Externals

As you can see from Table 1, the dimensions of the two machines are very nearly the same. The Yoga 900 (on the right in the photo below) is slightly narrower and thicker than the Yoga 3 Pro, but at a casual glance you wouldn’t see it.

clip_image010

As introduced with the Yoga 3 Pro, the hinge on the Yoga 900 is the distinctive “watchband” design, which I personally find appealing and which works smoothly and very well. Lenovo states that there have been improvements to the design in this generation.

clip_image012

Continuing on our tour of the externals, we come across the first marked difference on the left hand side of the machines. The Micro-HDMI port of the Yoga 3 Pro has been replaced with a USB-C port in the Yoga 900, which (according to the Yoga 900 User Guide) supports USB 3.0, native DisplayPort 1.2 video and VGA/HDMI output. Not (yet) having suitable USB-C cables or adaptors, I couldn’t test this out for myself. Nonetheless, I think that Lenovo is right to be forward-looking with adopting USB-C.

clip_image014

The other ports on this side of the machine remain the same. In the photo above, the first port can act as a standard USB 2.0 port, but it is also the charging port for the Yoga 900/Yoga 3 Pro. Lenovo provide a special USB cable for this purpose, which has a connector that is physically different from a standard USB male cable (it has a small “nub” on one side). The second port is a standard USB 3.0 port, while on the other side of the USB-C/Micro-HDMI port is the card reader port. Here’s a photo of the special USB charging cable connector (above) compared with a standard USB 2.0 connector (below):

clip_image016

Looking at the right-hand side of the machines, one thing immediately leaps out because of its absence. Unlike the Yoga 3 Pro, the Yoga 900 has no rocker switch for volume control.

clip_image018

Everything else is there – but no physical volume control switch. I’m a little surprised by this. It means that the only physical switches for volume control on the Yoga 900 are on the keyboard. For an ordinary laptop, that would be perfectly sufficient. However, this is a Yoga – when placed into one of the other modes (Tent, Stand or Tablet), the keyboard is disabled. Every other tablet (and smartphone) device that I’ve ever used has had a rocker switch on the side of the device used as a volume control; the Yoga 3 Pro has it, so why has Lenovo dropped it for the Yoga 900? On the face of it, this seems a strange design decision on the part of Lenovo.

Other than that, the Yoga 900 has exactly the same controls and ports as the Yoga 3 Pro on this side of the machine. From the left in the photo above: the power button, a recessed button that activates OneKey Recovery (of which more later, in the post on the Yoga 900’s software); the display rotation lock button, the headphone jack socket, and a USB 3.0 port. This last port can also be used to charge devices such as Smartphones via a USB cable.

Lifting the lids of the two devices reveals the next major difference; this time a welcome improvement. The Yoga 900 has a sixth row of keys – a line of dedicated function keys on the top row. It seems that Lenovo received negative feedback over the 5-row keyboard of the Yoga 3 Pro, so the traditional 6-row keyboard has been restored in the Yoga 900. An excellent decision that will please many keyboard jockeys.

clip_image020

The keyboard backlight now has two illumination levels in the Yoga 900, as opposed to the single level of the Yoga 3 Pro. However, there has also been a change to the design of the keys that I feel is a step backwards. As I think you can see in the photo above, the edges of the keys in the Yoga 3 Pro are translucent, whilst those in the Yoga 900 are solid black. This reduces the effectiveness of the backlight in the Yoga 900. For the sake of chic all-black design, backlight functionality has taken a hit. It’s a minor point, but I find the Yoga 3 Pro keys are better in this respect.

The trackpad appears to be the same in both machines, with an area of 60mm x 90mm. It’s a Synaptics trackpad, that unfortunately has not been certified by Microsoft as a Windows Precision Touchpad, perhaps because it is slightly smaller than Microsoft’s recommended optimal size of 65mm x 105mm. This also means that the trackpad settings are not integrated into Windows 10 Settings. More on the trackpad and keyboard in the Yoga’s Modes: Laptop section.

Turning our attention to the screen, both Yoga models have the same high-resolution (3200 x 1800) touchscreen displays, but Lenovo has improved the aesthetics by having a single piece of glass in the lid of the Yoga 900; the Yoga 3 Pro has a strip of black plastic running along the bottom edge. These high resolution screens are almost de rigeur in quality laptops and Ultrabooks these days, so it’s no surprise to see one in the Yoga 900. The display has a ratio of 16:9, which makes it ideal for some uses; less so for others. See my further thoughts on this in the Yoga’s Modes section.

Both Yogas have a Windows button positioned below the display, for use primarily when in Tablet mode. Neither Yoga has haptic feedback for this capacitive button (unlike Lenovo’s ThinkPad tablets). This could simply be because it is physically impossible for Lenovo to fit a haptic mechanism in such a thin lid, but I do somewhat miss this feature.

In comparison to the Yoga 3 Pro, the Windows button of the Yoga 900 is also more difficult to see in some lights. Of course, it could also be argued that, with the advent of Windows 10, the Windows button has become redundant, since, unlike in Windows 8.1, the Windows Taskbar with its Start button is always present – even in Tablet mode. It would not surprise me to see this button dropped altogether in the next generation of Yoga devices.

At the top of the screen is the Yoga 900’s webcam; capable of 720p @ 30 fps (the same as for the Yoga 3 Pro), along with the dual-array microphone.

The speaker grilles are positioned underneath on the Yogas. Those on the Yoga 900 are slightly larger than on the Yoga 3 Pro, although the specifications of the JBL speakers are the same.

Yoga 900 Internals

Lenovo heard feedback from customers that the performance of the Core M processor in the Yoga 3 Pro was slower than anticipated. Lenovo’s response is to include the latest (6th) generation of Intel Core processors, codenamed “Skylake”, in the Yoga 900. Two versions will be available in the Yoga 900 range; a Core i5 and a Core i7 model. These processors are a step up in speed and power compared to the Intel Core M processors used in the Yoga 3 Pro. See the Benchmarks section for comparative results.

Skylake also introduces a new generation of the graphics processor architecture, and the Yoga 900 has an Intel HD Graphics 520 engine[1], which, as can be seen from the benchmarks, improves 3D graphics performance significantly over the Intel HD Graphics 5300 in the Yoga 3 Pro.

The Yoga 900 can have up to 16 GB system memory installed – improving on the maximum of 8 GB of the Yoga 3 Pro. Storage for both Yogas is the same; either 256 GB or 512 GB SSDs can be specified. It’s a similar story for wireless connectivity; both will support 802.11 A/C Wi-Fi and Bluetooth version 4.0.

The battery is another area where Lenovo has improved on the Yoga 3 Pro as a result of customer feedback. Like many others, I found the battery life between charges on the Yoga 3 Pro to be disappointing. Lenovo has increased the battery capacity of the Yoga 900 to 66 Watt hours. That is a third more capacity than that of the Yoga 3 Pro. The Yoga 900 is very slightly thicker and heavier than the Yoga 3 Pro (14.9 mm vs 12.8 mm and 1.29 kg vs 1.19 kg), but it achieves its increase of a third in battery capacity at a cost of only 15% extra thickness and 8% in weight. it’s a sacrifice I’m happy to make for the increased running time on battery.

Both Yogas are equipped with cooling fans. See the benchmarks section for comments on effectiveness and noise.

There’s one omission that I personally find a little disappointing: there is no built-in GNSS to feed GPS coordinate data to the Windows Location service. It’s a hobbyhorse of mine – I feel that mobile devices should have a GNSS chip fitted as standard. Downloadable maps in map and navigation apps are standard these days, but I still can’t use the Yoga 900 (or indeed the Yoga 3 Pro) off the grid without an additional Bluetooth GPS logger to track its position.

However, that omission apart, the Yoga 900 is a very attractive looking Ultrabook, with an excellent display and connectivity options.

Benchmarks

Having attractive looks is one thing, but how does the Yoga 900 measure up in performance? I ran some standard benchmarks on both the Yoga 900 and the Yoga 3 Pro in order to have a comparison between them. I did a quick subjective performance test using a Digital Audio Workstation application that I run on my desktop PC. Finally, I ran a simple battery life test.

PassMark Benchmarks

PassMark Software provide benchmarking software and hardware. I downloaded their Performance Test 8.0 software and used it to run benchmarks on both Yogas. The results are shown in Table 2 below. I also downloaded HWMonitor from CPUID, to record the maximum temperature of the CPU reached when running the benchmarks.

Table 2

In the results table above, it is clear that the CPU and graphics performance of the Yoga 900 over the Yoga 3 Pro is much improved, particularly for 3D graphics. Only the disk performance remains unchanged between the two machines.

As a general principle, I don’t like fans in portable devices, and have expressly purchased tablets for myself that do not have them. Nonetheless, for Ultrabooks with the performance of the Yoga 900, it is probably inevitable that such a device will have a fan. During the running of the benchmarks, the fan on both machines could be heard. Subjectively, the loudness of both fans sounded the same to me. I did not find it intrusive – a hissing sound – and I think it would be at an acceptable level for most people.

What is interesting from the table above is that the maximum temperature reached by the CPU in both machines during the running of the benchmarks is the same. The i7-6500U processor in the Yoga 900 will certainly be giving out more heat than the M 5Y70 in the Yoga 3 Pro. Given that the fans were equally loud, this would seem to support Lenovo’s claim that they have improved the cooling system in the Yoga 900.

Windows System Assessment Tool

The Windows System Assessment Tool was first introduced by Microsoft in Windows Vista as a means to compare the performance of the hardware of Windows PCs. For Windows Vista and Windows 7, Microsoft provided an applet (the Windows Experience Index applet) to display the results. Although Microsoft no longer provides this applet in Windows 8.1 and Windows 10, the assessment telemetry is still in place and can be used by third-party tools to display the Windows Experience Index. I used the WEI tool from ChrisPC to display the results for both the Yoga 900 and the Yoga 3 Pro.

clip_image022

clip_image024

For the most part, the results from this set of benchmarks confirm the findings of the PassMark benchmarks. CPU, graphics, and memory performance is improved in the Yoga 900, whilst disk performance remains the same. For some reason the WSAT tool claims that 3D graphics performance is the same for both machines; I suspect that the PassMark tests are more rigorous, and give a truer picture.

Digital Audio Workstation Test

As a result of the improvements to the CPU, GPU and larger system memory, the Yoga 900 can tackle more demanding tasks than the Yoga 3 Pro. By way of a quick subjective experiment, I installed Cubase LE AI Elements 8 on the Yoga 900, and used it with a Cubase project that uses 10 virtual instruments in the HALion Sonic SE workstation, also running on the Yoga 900. This performed well.

clip_image026

Battery Life Test

Lenovo claims that the Yoga 900 battery can last for 9 hours between charges when playing HD video at 200nits. I did a simple test of battery life under the following conditions:

  • Display always on at 50% brightness
  • Speakers at 100% volume with Dolby Audio on and set to music playback
  • Continuous music playback via Groove Music
  • Music streamed from a media server via WiFi

Under these conditions, the battery lasted for 6.5 hours. Not the 9 hours claimed for by Lenovo, but certainly more than can be achieved by the Yoga 3 Pro under the same conditions.

Performance summary

As a result of this testing, it seems clear that the Yoga 900 will perform very well in activities involving both productivity (office work) and media consumption (watching movies/videos and listening to music). It can also be used for media creation work (digital audio). Battery life is improved over that of the Yoga 3 Pro.

Yoga’s Modes

A prime selling point of the Yoga is the fact that it can be folded into a variety of modes. At the time of introduction of the original Yoga back in September 2012, this was a unique innovation. Since then, the concept has been copied by other manufacturers such as Dell, HP, Toshiba and ASUS, which proves that imitation is indeed the sincerest form of flattery. It also clearly demonstrates that the concept is perceived to have market value. Lenovo followed up with the introduction of the “watchband” hinge in September 2014, and now with the Yoga 900 we can see both innovations in a mature form.

These are the four modes of the Yoga:

Laptop

The traditional laptop mode is probably the starting point for most people, and the mode in which I suspect most people will be using it for the majority of the time.

The Yoga 900 keyboard delivers in this mode. The extended keyboard, and its quality feel (something for which Lenovo has a reputation for), will please those who pound keyboards all day long.

I am less positive about the trackpad. As mentioned earlier, this is a Synaptics device that has not been certified as a Windows Precision Touchpad by Microsoft. The result is that it is not integrated in Windows 10 Settings, and Synaptics mimics the required Windows 10 touchpad gestures in their own driver. I also note that there are many complaints about the software driver in the community support forums of Lenovo. I feel that Lenovo should get this trackpad properly certified and fully integrated into Windows 10.

The display is excellent, high resolution, good colours, and, at 300nits, bright enough for me. It’s a 16:9 ratio display, so it’s ideal for watching movies. For office work (e.g. word processing in Word, Excel), I personally prefer at least a 16:10 ratio. Even better would be the 3:2 ratio of Microsoft’s Surface Pro 3 and Surface 3. The 16:9 ratio is also not ideal in the Tablet mode (see later). The Yoga 900 has a large bezel area surrounding the display. It should be possible to fit a 16:10 ratio screen that is the same width as the current display into the Yoga’s lid. If the (now redundant) Windows Button were to be dropped in the next Yoga generation, this would be very easy to do. The overall dimensions of the Yoga would then remain the same, but having a 16:10 ratio display would serve the Laptop and Tablet modes far better than the current 16:9 ratio display, in my opinion.

Tent

This mode is ideal for media (movies and videos) presentations, particularly in space restricted situations, e.g. on a shelf or an aircraft table. For viewing movies, of course, the 16:9 ratio of the display is now ideal. Couple the Yoga with a wireless presenter, and you can use this mode for PowerPoint presentations as well. In this mode the keyboard and trackpad are automatically disabled.

Stand

As an alternative to the Tent mode, the Stand mode can be used for media and PowerPoint presentations. It requires more space than the Tent mode, but the screen can be set to a greater range of angles for the best viewing experience. The keyboard and trackpad are automatically disabled in this mode also.

Tablet

The last mode is where the lid is completely folded back over the (disabled) keyboard, and to convert the Yoga 900 into a tablet. You can select to have Windows 10 automatically switch into Tablet mode, or to give you the option to switch manually. In this mode, the 10-point touchscreen comes into its own. However, I find that the size of the Yoga 900 (and the Yoga 3 Pro before it) makes for a slightly unwieldy tablet. While the overall size ratio is very close to that of an A4 pad of paper, it’s bigger, and it’s just too big for me. The 10.1 inch Lenovo ThinkPad 10 is much more my ideal size of tablet. The ThinkPad 10 also has an active digitiser and pen, which again I find important to have in a tablet. Artists also want pens with their tablets, and while many artists might prefer the larger size of the Yoga 900, without proper pen support, they will be crossing it off their list of devices to consider.

Talking of A4 pads of paper brings up one last point. One of the frequent uses of a tablet is for reading books or magazines. And once again, the 16:9 ratio of the Yoga 900 provides (in my view) a diminished reading experience over devices with 16:10 ratios (e.g. the ThinkPad 10) or 3:2 ratios (e.g. the Surface 3). Pages are rendered longer and narrower in 16:9, and the reading experience suffers as a result.

clip_image002[6] clip_image004[6] clip_image006[4]

I would certainly make use of the tablet mode of the Yoga 900, but for me, and my usage patterns, it would not be the most frequently used mode. Still, having the option is something that a traditional laptop could not offer me.

Overall Conclusions

In my opinion, the Yoga 900 is a clear advance over its predecessor, the Yoga 3 Pro. Lenovo has listened to customer feedback and successfully addressed the major weak points of the Yoga 3 Pro, while maintaining its style and design quality. The plus points are:

  • Higher performance suitable for a wide range of consumer and business users
  • Improved keyboard
  • Improved battery life between charges
  • Excellent display
  • Build quality and style
  • Flexibility in use

There are some minus points (in my view):

  • The trackpad is not certified as a Windows Precision Touchpad
  • The physical volume control switch has been dropped.
  • Few Lenovo apps deliver real value-add (see this post for details).

And perhaps Lenovo could give consideration to the following for the next generation of the Yoga:

  • Move from a 16:9 screen ratio to at least 16:10, if not 3:2.
  • Include an active pen option in the Yoga 900 range.
  • Include a GNSS chip to deliver GPS coordinates in real-time to the Windows Location service.
  • Put back the volume control rocker switch.

It is a fine example of the Ultrabook class of computer. It also offers additional flexibility with the configurations that it can be folded into. I like it.


[1] Yes, the Yoga 3 Pro has Intel HD Graphics 5300, but despite being a higher number, it has a lower performance. Intel has changed their numbering scheme “in order to reduce confusion”. It seems to me to have done precisely the opposite.

  2. Matt Healy says:

    Sounds like an excellent device if one wishes to use a single device in multiple modes. My own preference is to have multiple single-purpose devices. For intensive work, I use a rather heavy “desktop replacement” style laptop with docking station. For light work, I use a “thin and light” style laptop (sacrificing some performance for portability). For e-books, web browsing on the sofa, videos, etc., I use a tablet. For meeting notes, I use a Bluetooth keyboard with the tablet. For maximum portability, I use my smartphone.

    I just find that each dedicated single-purpose device works better for that purpose than the compromises needed with a multi-mode device. Also, single-purpose devices tend to cost less than multi-mode devices with comparable specifications.

    • Geoff Coupe says:

      “single-purpose devices tend to cost less than multi-mode devices with comparable specifications” – almost certainly true, but then you need more of them 🙂 Swings and roundabouts…

  3. Woot! Love this very detailed review! #lenovoin

  4. Does the 900 support charging over the USB type C connector?

    • Geoff Coupe says:

      If you mean charging of the Yoga 900 itself, then not as far as I’m aware. Charging is done only via the special USB 2.0 port, I believe. The USB 3.0 port between these two ports can be used to charge external devices such as smartphones.

    Thanks for this. I agree 100% about the screen ratio. Bummer i did not read you post before ordering. The fact i did order is that i absolutely need/want 16GB of ram. I was glad reading about you bench test and your analysis of the fan. Having tinnitus i’m very sensitive to fan noise.

    Mind – the USB-C to drive an external display. I sifted though all questions on the US site – lots of questions about how/what’s needed but no answer. Tried to buy a “USB-C to DP” here in northern Europe. The only one i can find is an obscure one for the Mac. I have not been able to find any cable or some such from a 3rd party or Lenovo. This scares me a bit.

    As an indie developer with the need for a capable machine at /low weight/ and /low noise/ i’d be ready to offer battery life for the faster memory option (would it be available) but i think this machine will serve me ok for at least 3+ years.

    Re the rocker switch, as you call it, it is a setback that could ruin your family life. The wrong sound at the wrong time at the wrong volume. I’ll say no more.

    Lenovo is going to replace this unit as it refuses to lit up the screen after having gone to sleep. An i’ll mention my worries about driving the everyday-work screen.

    Also – i find the machine a bit too “plastic”. Of course, a device like this needs to be able to give some physically or it would break immediately. But i’m worried every time i pick it up and especially when i switch from closed to tablet (all 360 degrees). It feels like i’m about to break it. Also – and i would not have accepted this unit for this reason – the left palmrest does not lie flush against the table surface so every time i rest my left hand i feel the “bump” of the plastic foot. Utterly annoyng. If you have some comments on the physical build properties after further use, i would appreciate it.

    No mention on the “paper sceen” feature. Having had a Vaio for 6½ years, maybe this feature is legio today. But i find it rather nice. On that note – what is the reason for being able to turn off the screen backlight? It’s completely impossible to see anything (?) haven’t tested it in bright sunlight though.

    Thanks,

    /Dany
