One of the main problems of most "smart" watches, including models based on the Android Wear operating system, is rather short battery life. In this case, manufacturers can significantly speed up the process of charging watches, which may well be considered an alternative solution to the problem. That is, according to rumors, Oppo did with her unannounced “smart” watches. According to a source familiar with the situation in the company, the watches from Oppo will be running Android Wear, and their announcement will take place soon enough. The main difference between Oppo smart watches and their Android Wear counterparts will be the time required to charge the battery. According to the source, the device will need only 5 minutes to fully charge.
Thus, if these rumors are confirmed, Oppo watches can be easily recharged in the free 5 minutes, without worrying that they will sit at the wrong time.
Recall that the company has long been working in this direction. Last year's flagship Find 7 was introduced with proprietary fast charging technology VOOC, which allows you to charge your smartphone from 0% to 75% in half an hour, and with the Oppo N3, the company introduced the second version of this technology.
