Data comes from HUAWEI lab tests, by comparing the CPU performance of the HUAWEI MateBook B3-420 (11th Gen Intel® Core™) with that of its predecessor in multi-core benchmark tests. Performance data may vary depending on the specific product and testing conditions.
2.4 Gbps is the theoretical maximum speed (data from Intel). This feature only works with routers that support Wi-Fi 6. The network speed increase data comes from HUAWEI lab tests, by comparing the HUAWEI MateBook B3-420 (11th Gen Intel® Core™) with its predecessor HUAWEI MateBook B3-410 (10th Gen Intel® Core™).
Performance Mode can only be activated when power supply is sufficient. It is not enabled by default. Once activated, CPU and GPU performance is instantly increased. This may cause the surface to heat up and the fans to produce more noise.
Data comes from HUAWEI lab tests, by comparing the cooling effects on the HUAWEI MateBook B3-420 with those on its predecessor.
56 Wh is the rated capacity.
Data comes from HUAWEI lab tests, with all test items installed and the display brightness set at 150 nits. Actual battery life may vary depending on usage habits and laptop settings.
The Huawei Share Multi-screen Collaboration feature is only supported on certain HUAWEI MateBook laptops and Huawei phone models. For more details, please refer to Huawei official website. (https://consumer.huawei.com/za/support/huaweishare/)
Typical values.
The Low Blue Light certification means that when Eye Comfort mode is enabled, the test item's display effects conform to a set of low-blue-light standards approved by TÜV Rheinland (colour temperature adjustment effects are not included in the test). Actual blue light filtering effects may vary according to the wavelengths present. Nonetheless, the HUAWEI MateBook B3-420 is not a medical device, and Eye Comfort mode is not intended for treatment purposes.
The measured thickness does not include the foot pads. Thickness and weight may vary depending on the specific product configurations, manufacturing techniques, and measurement methods.
The multi-function USB-C port can be used for charging and data transmission.
Data comes from HUAWEI lab tests. All test items were put through rounds of 15-min PCMark 10 Modern Office sessions, with the authentic 65 W charger and cable used, the battery level at 1% when charging started, and the laptop set in standby mode. Actual performance may vary depending on the specific product, external conditions, and usage habits.
