Infinix Brought Wireless Charging Tech To CES That Can Juice Up Your Devices From Eight Inches Away
It's been a while since we've seen wireless charging demos from Oppo and Xiaomi, so we were surprised when a new product from fellow Chinese phone brand Infinix was spotted at CES 2024. This "AirCharge" technology uses low-frequency magnetic resonance to transfer up to 7.5 W of power instantly. wireless and works at a distance of up to 20 cm (7.87 inches), double that of Oppo's previous demonstration, and works at angles of up to 60 degrees. . . To be precise, you get between 1 and 5 W per device at a distance of 10 cm (3.94 inches) to 20 cm.
Infinix considers this case to be ideal for users who want to keep their cellphone on while playing games or watching videos without needing cables. With a longer charging distance, you can also install an AirCharge panel under your desk to create a hidden charging area. Until then, Infinix will have to find a way to avoid accidentally heating nearby metal objects. There are external object detection methods for existing “2D” wireless charging solutions, but things get more complicated when the charging area changes from “2D” to “3D”.
Another safety measure to keep in mind is if the distance between your phone and the charging point suddenly decreases: it is not a good idea to suddenly increase the voltage on the device. Therefore, Infinix has implemented (and patented) surge protection circuitry on both sides of the chain. The company has not yet launched AirCharge in its production devices, but hopes to use the technology to advance industry standards for over-the-air wireless charging.
Infinix also showed off E-Color Shift technology which uses Prism 3 E Ink to change the color pattern on the back of the cellphone. This feature supports eight primary colors coupled with multi-level gradients, and can be applied in templates with more than 100 custom fields. Like regular E Ink displays, this Prism 3 panel updates with new color models without consuming any power.
Once the company finds a way around the thermal and thickness issues, it hopes to bring these native features to consumer devices within a year or two. At this point, you can adjust the color model through the app, which we couldn't see because our demo used a dummy phone. Lenovo is also considering using this display technology on its laptop covers.
Finally, Infinix introduced 'Extreme-Temp Battery' technology for users who want to brave the cold weather. While the capacity of conventional lithium-ion batteries is drastically reduced or even damaged at low temperatures, the Infinix Solid State Battery will continue to function even at temperatures as low as -40°C or -40°F. Likewise, when measured at -20°C or -4°F, Infinix solutions will provide 50% to 300% longer standby time than other solutions. We might see this battery technology in Infinix phones in the second half of 2025.
