The tantalizing promise of true wireless charging – not just leaving your phone on a charging pad – it feels even more real as companies like Xiaomi, and now Oppo, demonstrate prototypes of their respective approaches to technology. Although if Oppo’s wireless charging reaches consumers, your phone can feel as restricted as it does with a cable attached.
Through the company Weibo account (a Chinese microblogging website similar to Twitter), Oppo shared a video to coincide with the Mobile World Congress, Shanghai, which begins today. The video introduces the Oppo X 2021 rollable smartphone concept, first revealed last November featuring a flexible OLED screen that rolls up to stretch and shrink your screen size, and charges wirelessly on a pad that doesn’t actually require the device to be directly on the charging coil.
Wireless charging technology currently available to consumers is based on tightly wound coils of cable located in the charger, as well as internal devices that support it. When placed close to each other, electricity flowing through the charging coil induces a current in the device’s coil that allows the battery to charge without physically inserting a wire. But the coils must be placed very close to each other for this phenomenon to occur, making it difficult to use a device while it is charging. It’s why Apple has added the MagSafe feature to its iPhone 12 lineup, ensuring that a wireless charger stays connected to the devices (and the charging coils stay aligned) even if the phones are picked up and used.
It’s convenient, but not nearly as convenient as true wireless charging, which businesses like Ossia has been demonstrating at CES for a few years. Ideally, a device that starts charging when you simply walk up to a wireless charger, which has so far been shown to have a range the size of an average room in your home. Last month, Xiaomi announced its own wireless charging system called “Mi Air Charge Technology,Which works in a similar way to Ossia’s Cota wireless technology, although neither solution is available to consumers yet.
Oppo seems to be taking a different approach than Xiaomi and Ossia. The Oppo X 2021 doesn’t need to make physical contact with the wireless charging pad to draw up to 7.5 watts of power (a bit more than what the iPhone’s little cube charger offers). But the company’s wireless air charging also doesn’t allow users to walk around a room.
The phone can be lifted and moved.the load does not seem to depend on its orientation—but according to the verge, the distance is limited to about 10 centimeters (about 4 inches). The video Oppo shared on Weibo It also seems to indicate that a device must be kept on the charging pad at all times. It seems a bit more convenient than the limitations of an induction charger, but not nearly as convenient as Apple’s MagSafe solution. which makes a device easier to use while charging.
There is no timeline for when Oppo’s over-the-air wireless charging might be available to consumers. if ever-depending on how the comments are during the Mobile World Congress, Shanghai. But while it is a step in the right direction, we are more inclined to wait for Ossia and Xiaomi to deliver their solutions. They offer more freedom and flexibility.
