Lenovo’s “Yoga Book 9i Gen 8 (13th Gen Intel Core)” is an unusual dual-display laptop. This may seem insignificant, but it will increase your productivity by increasing the desktop space. However, the price is quite high. It is suitable for those who pursue romance rather than cost-effectiveness in their computers. The amount of information on the 2.8K x 2 screen is very largeThe Yoga Book 9i Gen 8 is a product in Lenovo’s “Yoga Book” series. The first generation of “Yoga Book” released in 2016 attracted much attention for its illuminated keyboard, and although it was a single screen, it could also be used as a handwriting tablet. The second generation is the “Yoga Book C930” released in 2018, which uses an E-Ink panel on the keyboard surface. The series will adopt dual screens from here, but I think it is more like a main screen + sub-screen, and I can’t get rid of the impression that it is a bit boring. By using two identical panels, the Yoga Book 9i Gen 8 realizes a true dual-screen display. It seems like a complete package, but Lenovo Yamato Research Institute, which builds ThinkPads, is said to have been involved in the development of the Yoga Book series, so there may be some surprise models in the future. Ban three screens?
Regardless, the amount of information that the Yoga Book 9i Gen 8 manages to fit on its 2.8K x 2 screen is huge. The wide 2880 x 3600-dot desktop is equivalent to 5 times the pixel ratio of Full HD and 1.25 times the pixel ratio of 4K. Although the screen is actually enlarged by zoom, it doesn’t show as much information, but it can still show more information than the average laptop. Anyone who has used a computer will agree that the larger the desktop, the more efficient you can be.
Lenovo “Yoga Book 9i Gen 8” battery lifeBattery life is not disclosed. Therefore, when we used “PCMark 10” to measure the driving time when performing business tasks (web browsing, document creation, video chat, etc.), the standard performance setting was 11 hours and 12 minutes, and the power saving setting was 9 hours and 29 minutes until the battery was exhausted. The reason for the short driving time under the power saving setting may be that some processes were running in the background without my notice (the measurement took a long time, so I couldn’t re-measure it) This may be due to the large battery capacity of 80Wh. Mobile laptops are generally around 45-60Wh. Since the Yoga Book 9i Gen 8 does not have a physical keyboard, the battery may be installed in the vacant space (in fact, you can find it by disassembling it and looking inside, but this time it was borrowed by the manufacturer) (so it was not disassembled).
About the sound of the optical driveThe noise of the optical drive (the noise of the fan rotation and the wind noise of the exhaust port) is usually not a problem. But when it is heavily processed under the high-performance setting, the sound will be a bit loud. On the other hand, under the maximum (performance) setting, the high output state of 35 to 42W lasts for about 1 minute, and then fluctuates slightly around 23W. The CPU temperature is also high, reaching 88 degrees, but it lasts for a short time and then stays at around 72 degrees, which is a range without problems. Since the first generation of the Yoga Book series came out, some enthusiasts have called it a strange “abnormal PC”. The Yoga Book 9i Gen 8 has similar comments, but I personally think it is much more practical than its predecessor.
It’s a bit difficult to use on the mobile sideGenerally speaking, laptops with 13.3-inch displays are suitable for mobile use. Each screen of the Yoga Book 9i Gen 8 is 13.3 inches, so it takes up the same space as a mobile phone when the screen is closed. But please note that when using two screens, the screen size is quite large. The Yoga Book 9i Gen 8 uses the Core i7-1355U, emphasizing power-saving performance. The styling and panel used make it look like it can be used for heavy creative work, but it does not have the ability to process large amounts of data in Photoshop or edit 4K videos. First of all, 16GB of memory is the standard capacity for PCs, and if you use heavy software that takes up a lot of memory, you need at least 32GB. If you understand this and still want to implement dual monitors on a PC, I think it’s worth buying. It’s no longer a complicated topic like cost-effectiveness, but a simple romantic issue. “I bought it because I wanted it”, isn’t it great? I don’t know if I will be satisfied with it, but I feel the future is certain.
