A 14.2 inch laptop weighing only 798g, using the Kirin XE90 chip and HarmonyOS is enough to make users consider leaving the Windows or macOS ecosystem, or is the super light advantage not enough to change usage habits
On August 14, 2026, Huawei MateBook Pro S officially entered the first sale in China after being launched by Huawei on August 5, 2026. According to information compiled by Huawei Central from Huawei, the product attracted special attention thanks to its weight of only 798 g and 11.9 mm thinness, introduced as the lightest all-metal 14-inch laptop in the world. (Huawei Central)
1. Weight of 798g is the biggest difference
Huawei achieves a weight of 798g by using lithium magnesium alloy, three-part motherboard design, and integrated body structure. MateBook Pro S maintains a large 14.2-inch screen in a body that is only 11.9 mm thick. Huawei Central compares the device's weight to the MacBook Air at 1.23 kg, meaning the MateBook Pro S is about 432 g lighter according to the figures used by this source. (Huawei Central)
This is not simply a race to lose a few dozen grams. Bringing a 14-inch notebook below the 800g threshold has practical implications for groups of people who frequently travel, especially when the device still integrates an OLED screen, 54 Wh battery and active cooling system.
2. Kirin XE90 focuses on performance per watt
MateBook Pro S uses the Kirin XE90 processor developed by Huawei. At a technical event on July 29, 2026, Huawei announced that the Kirin XE90 improves single-core performance by 23 percent, power efficiency by 25 percent, and NPU performance by 40 percent compared to the Kirin X90. (Huawei Central)
The notable point lies in Huawei's orientation. Instead of just pushing maximum performance, the Kirin
Huawei also announced that the operating capacity of the MateBook Pro S can reach 20 W. The above figures on performance and efficiency gains are figures published by Huawei, and should not be understood as independent benchmark results between the MateBook Pro S and Windows laptops or MacBooks.

4. The 54 Wh battery in the body weighs less than 800 g
Huawei uses a 54 Wh battery with a 10 percent high-content silicon anode. According to the company, this technology increases energy density by 15 percent while reducing battery weight by 10 percent. Huawei announced that the MateBook Pro S can play local 1080p video continuously for up to 18 hours. (Huawei Central)
The number 18 hours is the result according to the manufacturer's testing conditions. Actual usage time will depend on screen brightness, network connection, application and processing load.
5. Selling price converted to VND
During the sale on August 14, 2026, Huawei Central said Huawei put the standard and PaperMatte versions on the shelves first. Privacy Edition and Collector’s Edition are expected to be available from August 28, 2026. (Huawei Central)
Version Configuration Price in China Conversion for reference
Standard 16 GB + 512 GB 7,999 CNY about 30.96 million VND
Standard 24 GB + 512 GB 8,999 CNY about 34.83 million VND
Standard 24 GB + 1 TB 10,499 CNY about 40.64 million VND
PaperMatte 24 GB + 512 GB 9,999 CNY about 38.70 million VND
The reference conversion rate using the exchange rate on August 14, 2026 is about 1 CNY equivalent to 3,870.64 VND. Actual prices when imported or distributed in other markets may vary due to taxes, fees and sales policies. The original price in China is recorded by Huawei Central from the opening sale.

6.HHuawei is building a different PC direction
The MateBook Pro S is notable for more than just its weight. The product combines Kirin XE90 processor, HarmonyOS, OLED screen and many hardware components optimized by Huawei according to its own ecosystem.
This shows that Huawei's PC strategy is increasingly separating from the traditional laptop model that depends on Windows and Intel or AMD processors. However, actual competitiveness will depend significantly on the maturity of HarmonyOS on PC, software ecosystem, application compatibility and performance in professional tasks.
So, 798 g may be the parameter that makes the strongest impression, but the Kirin
