The unassuming Iron Grey chassis of the Lenovo Yoga 15in houses a seriously powerful laptop. The display is covered with glass, which makes it glossy. The lower results are probably mainly caused by the higher display resolution. However, the 4K LCD of the Yoga 730-13IKB is not a wide-gamut display. With A 4K touch display, powerful CPU and blazingly fast SSD, and decent gaming capabilities, it’s a true all-rounder. 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. With 93%, the distribution of brightness is very consistent. However, power consumption and clock speeds decrease just as quickly, and the CPU speed levels off at just 900 MHz after two minutes. The sole innovation here is that both Type-C ports are supporting Thunderbolt 3 now, whereas the predecessor had only one Thunderbolt 3 port. However, in this price range, there are some serious 2-in-1 rivals. It becomes clear at this point that this is not a high-end convertible: All the more expensive competitors are better equipped. If PWM was detected, an average of 9589 (minimum: 5 - maximum: 142900) Hz was measured. You should be able to do some semi-professional image editing. The HP Spectre x360 13, for example, features a 60-Wh battery, the Lenovo Yoga 920-13IKB even a 70-Wh battery. The other competitors have 13.3-inch displays. Thanks to the high contrast ratio, black does not look like dark gray. Apart from the removal of chrome elements and the different color options, Lenovo has not changed the materials of the case. In sum, we can recommend the Yoga 730-13IKB - but not the tested configuration with 4K display. The connectivity has been slightly improved: The laptop features two Thunderbolt 3 ports instead of one. Expert Reviews™ is a registered trade mark. It’s got two levels of LED backlighting, too. The Lenovo Active Pen 2 works well too. Memory operation in single-channel mode adversely affects the performance of a GPU without dedicated memory. This is a decent value that we expect from a device in this price range. Lastly, we criticize the CPU throttling during battery operation. The speed is satisfactory for a PCIe-NVMe SSD: It is faster than the often-used Toshiba XG5 but slower than the Samsung PM961. On paper, this is a 2-in-1 laptop which has it all: a 4K touch-screen display, fast CPU and PCIe SSD, powerful Nvidia discrete graphics and generous connectivity options. They’re plenty loud enough, but when playing music I found the audio to be lacking in clarity, especially once you step away a few paces. Lenovo Yoga C730 first look: 2-in-1 with a 4K AMOLED turns heads Review Lenovo Yoga C730 first look: Lenovo's Yoga C730 boasts a big Ultra HD AMOLED panel that features Windows Ink stylus support. The 3DMark11, which we ran directly after the stress test, achieved a normal result. The model number is HFS512GD9TNG. The laptop even comes with a bundled stylus, the Lenovo Active Pen 2, so it’s ready for more creative endeavours right out of the box. For a 4K display model, you’re looking at a whopping £1,999, minimum. Our display calibration tests revealed that it’s far from perfect, however. When people hear the word Yoga, they first think about twisted bodies. The fingerprint reader with touch technology, which is integrated in the palm rest, is probably rather a convenience feature than a serious security feature. Two models (81CT0023GE & 81CT008EGE) are nearly identical. The Lenovo Yoga 730-13IKB features a single M.2-2280 SSD.
