The tempting promise of true wireless charging (not just placing the phone on a charging pad) feels even more real as companies like Xiaomi, and now Oppo, demonstrate prototypes of their respective approaches to technology. Although yes from Oppo wireless charging If you reach consumers, your phone may still be as restricted as with a connected cable.
Through the company Weibo account (a Chinese microblogging website that is no different from Twitter), Oppo shared a video coinciding with Mobile World Congress, Shanghai, which begins today. The video includes the Roll-up Oppo X 2021 smartphone, first revealed last November with a flexible OLED screen that rolls to stretch and reduce screen size, charging wirelessly on a pad that doesn’t actually require the device to be seated directly on the charging coil.
The wireless charging technology currently available to consumers is based on tightly wound wire spools located on the charger, as well as on the devices that support it. When placed close to each other, electricity flowing through the charging coil induces a current in the coil of the device that allows the battery to be charged without any cables being inserted. . But the coils must be placed very close to each other for this phenomenon to occur, which makes it difficult to use a device while charging. That’s why Apple has added the MagSafe feature to its iPhone 12 line, ensuring that a wireless charger stays connected to devices (and that the charging coils stay aligned), even if they are picked up and phones are used.
It’s convenient, but not as convenient as real wireless charging, which companies like Ossia has been proving it at CES for a few years. Ideally it is a device that starts charging when approaching a wireless charger, which has so far been shown to have an approximate range the size of the average room in your home. Last month Xiaomi announced its own wireless charging system called “Mi Air Charging Technology,”, Which works similarly to Cota d’Ossia wireless technology, although no solution is yet available for consumers.

Oppo seems to take a different approach than any other Xiaomi and Ossia. The Oppo X 2021 does not need to make physical contact with the wireless charging pad to consume up to 7.5 watts of power (slightly more than that provided by the iPhone’s small cube charger), but the company’s wireless air charge also doesn’t allow users to walk around a room.
You can pick up and move the phone—it seems that the load does not depend on its orientation—But in accordance with the Virgin, the distance is limited to about 10 centimeters (approximately 4 inches). The video Oppo shared on Weibo it also seems to indicate that you need to keep a device on the charging platform all the time. It seems a little more convenient than the limitations of an induction charger, but not as convenient as Apple’s MagSafe solution, which makes it easier to use a device while charging.
There is no timeline on when Oppo’s wireless air cargo can be made available to consumers: if everdepending on how the comments are during Mobile World Congress, Shanghai. But while this is a step in the right direction, we are more inclined to wait for Ossia and Xiaomi to present their solutions, which offer more freedom and flexibility.
