OPPO Band (OB19B1)

Followers of the healthy lifestyle cult, who are not ready to shell out a tidy sum for advanced smartwatches, will like the first fitness tracker from OPPO with the prosaic name Band.

Colour AMOLED panel

The model has a certain similarity with competitors under the sign of the Xiaomi brand. Structurally, the tracker consists of a capsule with sensors and a silicone strap. The front surface of the capsule with electronics is covered with a colour AMOLED screen framed by visible frames with excellent image readability in the sun. The caliber of the display is 1.1", and its resolution is 294x126 pixels. At the user's disposal, 5 gradations of brightness of the AMOLED panel are provided. The display “lights up” when you touch it with your finger or raise your wrist.

Night saturation

On the “contact” side of the capsule body, which is adjacent to the “carrier’s” hand, there is an optical heart rate sensor and sensors for determining the level of blood oxygen saturation. During the day, saturation is measured “on call” by the user, at night, OPPO Band monitors SpO₂ indicators automatically, improving the accuracy of information about sleep quality. Detailed sleep phase charts are drawn in the associated HeyTap Health mobile app.

Achievements of goals

The sports potential of the model is revealed by 12 preset training modes: running, walking, cycling, swimming, yoga and less popular ones like cricket. Tracking sports is done with the measurement of time, productivity and load on the body. At the same time, the device collects information about the user's activity and fills in the goal achievement scale on the screen. Among the shortcomings of the OPPO Band, they note the need to remove the capsule from the charging strap. Fortunately, this action will need to be performed every 10-12 days — this is how much energy reserves are enough in the cells of a 100 mAh battery.
