Oppo introduced a new wireless charging solution that works when a phone is within 10cm (3.9 inches) of a charging cradle. The company showed off its wireless aerial charging technology in a 30-second clip on its Weibo page to coincide with MWC Shanghai. The clip shows the Oppo X 2021 roll-up concept phone, announced in November, charging above the pad, even when held at an angle. The technology offers charging speeds of up to 7.5W, Oppo explains.
The Chinese manufacturer is the latest to announce a truly wireless air-charging solution, following teasing from Xiaomi and Motorola earlier this year. In January, Xiaomi announced Mi Air Charge technology, which it claims can charge multiple devices at 5W “within a range of several meters”. The next day, XDA Developers reported a demo from Motorola that showed one of its phones charging 100cm (40 inches) from a charger.
At 10 cm, the range of Oppo technology is more limited than that of Xiaomi’s competitor, Android Authority Remarks. The presenter of the video makes a very deliberate effort to hold the phone directly over the charging mat. However, charging works even when the phone is tilted slightly over the wireless charger and while playing a video.
Awards like this are currently academic since none of these technologies have been released into commercial products. Xiaomi has confirmed that its tech won’t be ready for release this year, and the roll-up phone Oppo used for its demonstration also doesn’t have an official release date.
In addition to developing wireless chargers that work over longer distances, manufacturers are also working to speed up standard wireless charging. Xiaomi is developing an 80W wireless charging solution, which it announced just months after Oppo revealed its own 65W wireless charging technology.
Update February 23 at 6:53 am ET: Updated with the official name of the charging solution and more details.
