The sleep log distinguishes fewer sleep phases than usual, but indicates when the saturation has dropped below the threshold of 90% during the night. If you are looking for an everyday companion with nice features without high demands, you will get a nice wearable in the Oppo Band Sport that allows you to control the smartphone's music and camera, see weather information, and much more.
In addition, the connection to the smartphone was interrupted during the cycling tour in the test, which is why the route recording ends prematurely. The automatic pause detection does not work when cycling. On the positive side, Oppo automatically pauses the log when you stop while walking or running. On the 2nd run, in conjunction with the smartphone and its GPS, the log also shows the route, vs Xiaomi's Mi Smart Band 6, but still comparatively few details. However, the Oppo Band Sport only managed 2.62 km (~1.6 mi) without a smartphone over a distance of 5.2 km (~3.2 mi) in the test. Trackers like the Band 6 from Honor or Huawei do this quite well and are sometimes sufficient for recreational athletes. Fitness trackers that don't have their own GPS, like the Oppo Band, estimate stride length based on height, age and weight, and determine a distance even if you leave your smartphone at home. If you care about your pace, you'll have to take your smartphone with you when you run. Besides running and cycling (indoors and outdoors), they include a fat-burn run, yoga, rowing and the elliptical trainer.
There are 12 sports modes installed on the Oppo Band Sport. Sensors include a 3-axis accelerometer and optical sensors for heart rate and blood oxygen saturation (SpO2). The brightness does not regulate automatically, there are 5 levels to choose from for adjustment. The color space used in the film industry might not really seem necessary for a wearable, but it certainly cannot hurt if you immortalize your pet, boyfriend or girlfriend as the background - which is possible via the settings for the watch face. According to Oppo, the screen covers the DCI-P3 color space completely. For comparison: The Mi Smart Band 6 has a resolution of 152 x 486 px on a diagonal of 1.56 inches and is clearly the winner in this respect. With the same display diagonal of 1.1 inches, the pixel density of 291 ppi is also consistent. The AMOLED display's resolution of 126 x 294 px is just as high as that of the Amazfit Band 5. The operating system, apps and installed watch faces share 16 MB. An Apollo3 from Ambiq with 1 MB RAM works in the casing. The polycarbonate casing is water resistant up to 5 ATM. The tracker weighs 23 g (~0.8 oz) with the band, just like the other two. Compared with the other two, however, it inserts level with the glossy plastic frame in the wristband, which looks nicer. The Oppo tracker can also be removed from the TPU band.
