Huawei Band 7 Review: Ultra Thin Design With 2 Week Battery Life

Smartwatches have become an integral part of our lives. The big disadvantage: its comparatively short battery life. If you want a longer battery life, the fitness bands from different manufacturers are a good alternative. The youngest member of this group is the Huawei Band 7.

Huawei officially released the Huawei Band 7. Officials said that this is Huawei’s thinnest smart bracelet, at only 9.99mm thick and weighing 16g.

The Huawei Band 7 uses a 1.47-inch AMOLED screen, 2.5D high-quality curved glass, a slightly narrow border design, a resolution of 194 x 368, and a new UI design.

Personally, battery life is the second biggest criticism of smartwatches. The biggest gripe is that they just seem chunky and thick in many cases. For these reasons, a smartwatch has never been allowed to adorn my wrist beyond a fitting. For me, the fitness bands were and are more attractive.


In terms of design, the Huawei Band 7 is available in 4 colors obsidian black, nebula powder, wild green and flame red, with a reinforced polymer fiber shell that adds delicate metal texture.

Whether you watch it with your eyes or hold it in your hand, you can feel that the design of the Huawei Band 7 is lighter and thinner. The thickness of the overall body is only 9.99mm. The thin and lightweight body design can fit the wrist nicely and wear. There will be no weight-bearing feeling when you get up, and you will not feel uncomfortable even when you wear it while sleeping.

In addition, the immense feeling of wearing the Huawei Band 7 on the hand is that it fits the wrist very well as if it fits on the skin. It has a near-insensitive wearing experience. It is very comfortable, and the wearing experience is still excellent. The thin design and high-end fashion The design style makes its appearance full of personality and exquisite.

Band 7’s sensor is a circular module, whereas Band 6’s sensor is a rectangular module (see images on the left and right).

There is a physical button on the right side of the fuselage of Band 7 (left) and Band 6 (right), but there is no physical button on the Xiaomi Mi Band (centre).
