智能手环进化。 虽然华为Band 4是我们测试的重点，但我们同时也评测了Band 4e。 虽然较小的健身手环提供的功能明显不足，但它具有一项很酷的非凡功能。
Huawei offers its fourth-generation fitness tracker in three different model versions. We have already tested the Huawei Band 4 Pro with OLED - it is the only model that offers GPS. Like the Band 4 Pro, the Band 4 also offers a heart rate sensor. In addition, it brings some typical smart band functions, such as the full display of notifications. In contrast, the Band 4e can only signal that a notification has arrived, without being able to display either the notification itself or from which app it came from. On the other hand, the Band 4e offers one particular function that not only the two other models cannot offer, but that is also very special in general. There is a 6-axis sensor that can record more precise information while running, from which the corresponding Huawei Health app then calculates the step pattern, landing force, and amount of time of ground contact, as well as the number, height, and duration of jumps while playing Basketball.
