Lenovo Yoga 730-13IKB (i7-8550U, 4K) Convertible Review

Benjamin Herzig, 👁 Andreas Osthoff, Tanja Hinum (translated by Moritz Jordan), 08/02/2018

Ambitious middle-class Yoga. Good quality at a low price - impossible? Lenovo attempts to fulfill this promise by releasing a middle-class convertible laptop playing in the upper league. You can read in this detailed review if this concept adds up.

When people hear the word Yoga, they first think about twisted bodies. Nevertheless, the computer manufacturer Lenovo succeeded to establish the term as a well-known brand name. Yoga is not as important as the brand “ThinkPad”, but since the announcement of the first IdeaPad Yoga in 2012, it is probably Lenovo’s second most important computer brand. The manufacturer removed the label IdeaPad from their consumer models years ago so that Yoga now appears as a single brand name. For their business models, however, they combined the powerful names “ThinkPad”, “Yoga”, and “X1” in a single device (ThinkPad X1 Yoga).

Today’s review unit is not as high-priced as the ThinkPad X1 Yoga. It is not even the flagship of the Yoga series for consumers, which is the Lenovo Yoga 920. The Lenovo Yoga 730-13IKB takes a back seat. It is made for customers, who want to buy a premium Yoga convertible but do not want to pay the price for the absolute flagship model. The classification for that matter is “upper middle class” rather than “upper class”. We are testing the most expensive configuration of the Yoga 730-13IKB featuring the Intel Core i7-8550U, a 512 GB SSD, 16 GB of RAM, and a 4K (3,840 x 2,160) display at a 1,399 Euro price point (~ $1,640). The Lenovo Yoga 920 would cost 300 Euros (~ $350) more with a comparable configuration but just 8 GB of RAM.

The Lenovo Yoga 730-13IKB competes against top-class devices such as the HP Spectre x360, the Dell XPS 13 2-in-1, and the Lenovo Yoga 920.

Case

Lenovo Yoga 730-13IKB
Lenovo Yoga 730-13IKB

The Lenovo Yoga 730-13IKB is an update of the predecessor Lenovo Yoga 720-13IKB. This means that the general assembly is virtually identical. However, Lenovo made some minor modifications on the outside as well as on the inside. The exterior of the Yoga 730-13IKB received a facelift. The milled chrome edges, for instance, are gone making the design more understated. Only the fingerprint reader and the TrackPad still have the chrome bezels, and the big Yoga logo on the display lid is chrome-plated. There are new color options available: dark gray, silver, and copper instead of gold, gray, and silver. Our review unit has a dark gray case. Lenovo changed the design of the rear edge of the laptop where the hinges are. Now, it is significantly more rounded and looks even more like the HP Spectre x360 13. Another minor change is the fan outlet design. On the bottom of the laptop are two small rubber feet on the front and one long rubber foot at the back, instead of a small rubber foot in each corner.

Apart from the removal of chrome elements and the different color options, Lenovo has not changed the materials of the case. The entire case is made from aluminum, except for the glass bezels around the display. Over all, the Lenovo Yoga 730-13IKB impresses with its high quality case and build quality. You can hardly warp or push in the base unit, and the display lid is relatively sturdy, thanks to the combination of metal and glass, which covers the display panel.

Therefore, the Lenovo Yoga 730-13IKB is not extremely far from the more expensive Lenovo Yoga 920, but there is one significant difference: The Yoga 730 has a conventional hinge design with two hinges, whereas the Yoga 920 features the luxurious “watchband” hinge. Both designs allow turning the display by 360 degrees for the tablet mode. The hinges of the Yoga 730 allow more wobbling than the hinge of the Yoga 920. It is not possible to open the display lid with one hand.

Together with the Dell XPS 13 2-in-1, the Lenovo Yoga 730 is the lightest model in the line of competitors. The Lenovo Yoga 920 is significantly heavier by nearly 200 g (~ 7oz), but it is also the largest convertible with its 13.9-inch display. The other competitors have 13.3-inch displays. All the convertibles have very small bezels on the sides and on top of the display but a large bezel below. This “chin” obstructs the otherwise elegant design and wastes some real estate. Maybe it is time for the manufacturers to switch to the 3:2 aspect ratio for displays, like Huawei does with its MateBook X Pro.

Size Comparison

Connectivity

Lenovo has barely changed the configuration of the ports compared to the Yoga 720-13IKB. There are two USB Type-C ports and a headphone jack on the left side and a single USB 3.0 Type-A port on the right side. The Yoga 730 does not feature an SD card reader or an HDMI port. More demanding users will probably not be satisfied with this limited selection of ports.

The sole innovation here is that both Type-C ports are supporting Thunderbolt 3 now, whereas the predecessor had only one Thunderbolt 3 port. This means most likely that the Thunderbolt 3 ports are connected via PCIe x4, because it is virtually always the case for laptops with two Thunderbolt 3 ports.

Communication

The only communication module of the Lenovo Yoga 730-13IKB is the Wi-Fi module Intel Wireless 8265, which is a standard component for more expensive laptops. The performance is satisfactory during day-to-day use, but the benchmarks showed a mixed result: The receiving performance is good, but the sending performance is significantly below average.

The camera and the microphones are typical for laptops - the quality is just sufficient for Skype video chats but not for more.

Security Features

Consumer laptops usually do not come with many security features. The fingerprint reader with touch technology, which is integrated in the palm rest, is probably rather a convenience feature than a serious security feature. However, it works snappy and reliably in combination with Windows Hello.

Accessories

The Lenovo Yoga 730-13IKB comes with a 65-W power adapter as well as a digitizer pen, based on the Wacom AES technology. Therefore, the Yoga could be particularly interesting for students, who need a convertible for taking notes. Suitable batteries are also included. We will take a deeper look at the pen in the section “input devices”.

Maintenance

It is possible to access the interior of the Lenovo Yoga 730-13IKB by removing the nine Philips T5 screws, which are securing the bottom plate. After removing the bottom plate, you can access important components such as the battery, the two small fans, and the M.2 SSD. You can upgrade the SSD, but the main memory is soldered to the mainboard.

Warranty

The Yoga 730-13IKB has a manufacturer warranty of 24 months - this meets the common standard in this field.

Input Devices

Keyboard

Lenovo equips its Yoga 730-13IKB with a chiclet keyboard with six rows of keys. The layout and design of the keys are still the same as for the predecessor. The bottom edges of the keys are slightly rounded, but the surface of the keys is flat and not concave like the keys on a ThinkPad. The key travel is quite shallow, the pressure point is not well defined, and the resistance is too small. Overall, the keyboard is usable but not really comfortable - in particular when compared to the ThinkPad keyboards.

Trackpad, Touchscreen & Digitizer Pen

The TrackPad sits in the center of the palm rest below the keyboard. The size of the TrackPad (10.5 x 7 cm, ~ 4.1 x 2.8 inches) is appropriate for a 13-inch laptop. There are no dedicated mouse keys, since the lower third of the TrackPad is clickable. The key travel of the TrackPad is short and crisp. The surface is very smooth and allows precise control of the mouse pointer - particularly in interaction with Microsoft’s Precision Touchpad drivers. The TrackPad is definitely a good one.

You can also use the touchscreen or the digitizer pen instead of the TrackPad. The touchscreen is able to detect ten fingers at the same time. It detects inputs very precisely. The pen is based on Wacom’s AES technology and features 4,096 pressure stages. In our short test, it worked flawlessly even on the edges of the display. The pen has a comfortable grip and two buttons, whose functions can be defined with the preinstalled Lenovo app. By default, one button activates the eraser function.

Lenovo’s spec sheet lists two display options for the Yoga laptop: a Full HD panel (1,920 x 1,080) for the base model and a 4K panel (3,840 x 2,160). Both are IPS panels. The display is covered with glass, which makes it glossy. Both display options have touch capability.

Today’s review unit features the 4K panel. Lenovo states a brightness value of 300 cd/m². We measured an average maximum brightness of 299 cd/m², which confirms this specification. The competing convertibles have similar brightness values, even the Full HD display of the Yoga 730-13IKB, which has been tested by our U.S. editorial department. The contrast ratio of the 4K display, however, is twice as high as that of the Full HD display. The HP Spectre x360 13 and the Dell XPS 13 2-in-1 are reaching similar contrast ratios.

The display has neither PWM, nor a significant backlight bleeding. With 93%, the distribution of brightness is very consistent.

Out of the box, the display has a noticeable green color cast, which can be eliminated by calibration. As always, we are providing the ICC profile for this purpose. Overall, the subjective impression of the calibrated display is very good. Thanks to the high contrast ratio, black does not look like dark gray.

With a coverage of 97% sRGB, the color gamut contributes to the good impression. This is a decent value that we expect from a device in this price range. You should be able to do some semi-professional image editing. However, the 4K LCD of the Yoga 730-13IKB is not a wide-gamut display. For this, it would have to cover more than 62% of the AdobeRGB color space.

Unfortunately, the display is not suitable for outdoor use even though the maximum brightness is 300 cd/m². Due to the glossy surface, we noticed plenty of disturbing reflections even in the shadow. The display is not bright enough to outshine these reflections.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
31.2 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 14.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.7 ms).
       Response Time 50% Grey to 80% Grey

In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 89 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8710 (minimum: 43 - maximum: 142900) Hz was measured.

The viewing angle stability is very good, which is typical for IPS displays.

Performance

As of now (end of July 2018), there are six different models of the Lenovo Yoga 730-13IKB available in the United States. Two models (81CT0023GE & 81CT008EGE) are nearly identical. The base model, which currently costs 999 Euros (~ $1,170), is available in dark gray or silver. Both colors are equipped with the same hardware components (Core i5-8250U, 8 GB RAM, 256 GB SSD, Full HD display). The more expensive configuration 81CT0080GE is exclusively available in the Lenovo online store. This one features an Intel Core i7-8550U CPU, 8 GB of RAM, a Full HD display, and a 512 GB SSD. The color of the case is silver. The remaining three models are equipped with 16 GB of DDR4-2400 RAM (which is soldered to the mainboard) and a Core i7-8550U CPU. The cheaper configuration of the three has a 256 GB SSD; the other two have a 512 GB SSD. Only the most expensive model, which is our review unit, features a 4K display.

Processor

Intel’s Core i7-8550U is an ultra-low voltage (ULV) processor with four cores. It has a thermal design power (TDP) of 15 W. The clock speed ranges between 1.8 and 4 GHz (Turbo Boost). You can compare the CPU with other processors in our CPU benchmark table.

Lenovo allows the CPU to have a significantly higher maximum power consumption of 33 W - but only for 30 seconds. This results in a good boost performance, however, the temperature jumps up to 97 °C (~ 207 °F). Therefore, the clock speed drops quickly from 3.1 GHz to 2.9 GHz. For a short time, the power consumption lies at 28 W. Even this performance cannot be delivered permanently. In the long run, the clock speed evens out at 2.2 GHz with a power limit of 14 W. This explains the relatively quick decline of performance in the Cinebench loop.

Cinebench R15 CPU Multi 64 Bit

Thanks to the good boost performance, the Yoga 730-13IKB takes the lead in our CPU benchmark table. In the end, however, the Lenovo Yoga 920-13IKB delivers a better performance, whereas the HP Spectre x360 offers roughly the same performance under load as the Yoga 730. At least, the Yoga 730-13IKB is faster than its predecessor Yoga 720-13IKB. This one had the same processor, but Lenovo re-engineered the cooling system, which is probably the reason for the better CPU performance of the newer model.

The CPU performance is throttled during battery operation. Here, the Yoga 730 reaches only 530 points instead of 630 in the Cinebench multi-core test.

System Performance

The system performance of the Yoga 730-13IKB is good, even though the PCMark results are slightly lower than those of the competitors. The lower results are probably mainly caused by the higher display resolution. During day-to-day use, however, the system was always running smoothly.

Graphics Card

Intel's UHD Graphics 620 is the iGPU standard solution for most of the Ultrabooks in 2018. Its performance highly depends on the RAM configuration. Memory operation in single-channel mode adversely affects the performance of a GPU without dedicated memory. Fortunately, the soldered RAM in the Yoga 730-13IKB operates in dual-channel mode, allowing the GPU to max out its limited capability.

We were unable to notice a throttling of the GPU performance during battery operation.

Temperature

Stresstest (Prime95 + FurMark)
Stresstest (Prime95 + FurMark)

The surface temperatures are very low when idle. They are rising slightly under load, particularly on the rear part of the case. We measured 46.2 °C (~ 115 °F) in the center of the bottom, which is noticeably warm but still uncritical.

The stress test with FurMark and Prime95 reflects the results of the Cinebench loop: CPU and GPU together are allowed to consume more than 30 W for a short time, causing the internal temperatures to rise significantly. However, power consumption and clock speeds decrease just as quickly, and the CPU speed levels off at just 900 MHz after two minutes. This indicates TDP and temperature-induced throttling. The 3DMark11, which we ran directly after the stress test, achieved a normal result. Hence, you should not experience throttling during day-to-day use.

Speakers

The performance of the speakers is not satisfactory despite the preinstalled “Dolby Atmos” app. The sound is unbalanced, and the volume is quite low. For example, the speakers of the HP Spectre x360 13 are slightly better. You should rather use external speakers or headphones instead of the Yoga’s internal speakers. The combined headphone and microphone jack works perfectly.

Energy Management

Power Consumption

The idle values of the Lenovo Yoga 730-13IKB are slightly higher than those of the competitors. Interestingly, only the Yoga 730-13IKB that was tested by our U.S. editorial department was performing even worse. This model had a Full HD display; our review unit has a high-resolution 4K panel instead. It could be possible that Lenovo has optimized the power consumption by firmware updates for the 4K model. The display of our review unit probably causes the majority of the higher power consumption when idle, compared to the Lenovo Yoga 920-13IKB or the HP Spectre x360 13.

The included 65-W power supply is adequate for the maximum power consumption of 54 W.

Battery Life

Charging time: 125 minutes
Charging time: 125 minutes

The Yoga 730-13IKB contains a lithium-ion battery with a capacity of 48 Wh, just like its predecessor Yoga 720-13IKB. It becomes clear at this point that this is not a high-end convertible: All the more expensive competitors are better equipped. The HP Spectre x360 13, for example, features a 60-Wh battery, the Lenovo Yoga 920-13IKB even a 70-Wh battery. Particularly in combination with the higher power consumption, this leads to sobering results for the battery test of the Yoga 730-13IKB: The laptop died after less than six hours in the Wi-Fi test. With values ranging between 9 and 11.5 hours, the competitors are clearly superior in this practical test.

The charging time is 125 minutes.

Lenovo Yoga 730-13IKB
Lenovo Yoga 730-13IKB

The Lenovo Yoga 730-13IKB is an interesting update of its predecessor. In some respects, the quality reaches that of the more expensive convertibles. In other cases, however, it is inferior.

Strong points of the Yoga 730-13IKB are the premium aluminum case and the relatively low weight. It is easy to maintain: Upgrading the SSD is simple, which is not common anymore for today’s consumer laptops. The 4K display delivers the promised brightness, a good contrast ratio, and almost 100% of the sRGB color gamut. It does not have any issues with screen flickering or backlight bleeding. The laptop has a pretty good TrackPad without any major weaknesses. Additionally, you can operate the laptop using the touchscreen or the digitizer pen. It is great that the pen is included and does not need to be purchased separately. An improvement over the predecessor (Yoga 720-13IKB) is the better cooling system, which allows better boost performance as well as better long-term performance.

The connectivity has been slightly improved: The laptop features two Thunderbolt 3 ports instead of one. Over all, the connectivity remains very limited. Unlike the TrackPad, the quality of the keyboard is not appealing. The fact that Lenovo does not offer a brighter display option is disappointing, because the glossy surface makes outdoor operation nearly impossible. 300 cd/m² are not bright enough for this purpose. Another point of criticism is the low performance of the speakers. The biggest flaw, however, is the battery life, which is much worse than that of the competitors, due to higher power consumption (caused by the 4K display) and smaller battery capacity. Lastly, we criticize the CPU throttling during battery operation.

Especially cheaper configurations of the Lenovo Yoga 730-13IKB with Full HD display offer a good price-performance ratio, which makes them recommendable.

In sum, we can recommend the Yoga 730-13IKB - but not the tested configuration with 4K display. Instead, you should save the money and choose the Full HD option - it is cheaper, offers the same brightness, and allows the laptop to have a longer battery life. The best alternative is probably the HP Spectre x360 13, whose starting price is slightly higher than the one of the Yoga 730-13IKB.
