No further details about the bracelet have been released yet, but we know that it will monitor users' heart rate and sleep. It also supports multiple sports modes and will measure SpO2 (blood oxygen saturation). In addition, the Oppo Band should feature NFC for payments, which was confirmed in an image on Oppo's website.
We can see that the Oppo Band has two types of straps, a black one, in which it fits in the center, and a white one, in which it appears to float. The latter has the same shape as the Evangelion custom version, but in other colors.
Other than these details, we don't have any other information about the Oppo band, so we can only speculate about what it will have. It's possible that it will have wireless charging, just like the Oppo Watch, but this has not yet been confirmed by the company.
According to the description on one of the sales websites, it can be waterproof up to 50 meters deep. This information has also not been confirmed by Oppo, so there is no guarantee that it will have this feature.
There is a strong possibility that the Oppo Band will be presented at the launch event of the Oppo Reno4 line, which was confirmed today for June 5th.
