On November 22, Huawei Japan released the fitness band “HUAWEI Band 4”. I borrowed it, so I tried it for a few days.
HUAWEI Watch GT 2 is also available as HUAWEI wearable. There is a difference between a smartwatch and a fitness band, but the main functions are actually the same. Of course, there are minor functional differences, but there is no significant difference in what you can do.
The display is a 0.96 inch TFT color screen with a resolution of 80 x 160. The surface is a touch panel, and all operations are performed on the display. There is no physical button on the main unit.
The screen is normally off and lights up when the wrist is returned. Unlike HUAWEI Watch, there is no function that always lights up.
This type of device generally uses a dedicated charging stand or charging cable, but HUAWEI Band 4 does not have that. When one side of the band is removed, the USB terminal appears and can be inserted directly into the charger or the USB port of the PC.
The battery is normally used for 9 days, but this is when sleep measurement is disabled. When sleep measurement and constant heart rate measurement are enabled, about 15% of the battery is consumed in one day, so it seems that the battery will last for about 6 to 7 days.
As notifications from smartphones, incoming notifications and notifications from various applications such as email can be displayed. Only the sender can check the mail on the list screen, and the subject is displayed by tapping. It is the same as HUAWEI Watch GT 2 that you can not confirm the text.
In addition, it can also measure the number of steps, distance, and activity time. However, it is difficult to check on HUAWEI Band 4 because the screen resolution is low. During the trial period, the time, the number of steps, and the presence of notifications were confirmed on the wrist, and the rest of the measurement data and notification details were confirmed on the smartphone. Although it has a display, it seems better to think of it as an instrument that you always wear.
By the way, there is no music operation function. It also functions as a remote shutter only when used with a HUAWEI terminal equipped with EMUI 8.1 or later.
One of the great benefits of wearing HUAWEI Band 4 is the acquisition of sleep logs. HUAWEI has been focusing on sleep measurement for a long time, and HUAWEI Band 4 is equipped with the same “HUAWEI TruSleep 2.0” sleep monitoring technology as HUAWEI Watch GT 2.
The measurement data and display contents are the same as those obtained with HUAWEI Watch GT 2. Even if the belt is included, 24.1g (actual measured value) does not get in the way lightly, so if the main purpose is to collect sleep logs, HUAWEI Band 4 is sufficient.
