Xiaomi is reportedly working on a new charging technology after which you may not need a charging adapter at all. There is no doubt that the way we charge smartphones has changed a lot in the last few years. More companies are now focusing on wireless charging technology but, if all things go as planned, Xiaomi’s tech may revolutionise the way smartphones are charged.

According to a report by GizChina, Xiaomi has applied for a patent with the state agency China National Intellectual Property Administration (CNIPA) which suggests that the smartphone maker has been working on a charging technology that can use sound to juice up a device.

The new charging tech will reportedly work on two components – a “sound collection device, a plurality of energy conversion devices, and a ‘power conversion device”. Xiaomi’s power conversion device will convert environmental vibration to mechanical vibration, which will then be converted into alternating current.

The power conversion device will convert AC into DC (Direct Current). If Xiaomi is actually able to roll out this tech, we will not need charging cables or bricks anymore. However, it sounds too ambitious for now and will take a while before the tech is actually ready for public use.

Xiaomi has been really active when it comes to charging tech. We already know that it is working on a 200W fast charging solution that may debut on a flagship phone later this year. Also, it had unveiled the Mi Air Charge technology which can be used to wirelessly charge multiple devices at the same time.

“Charge multiple devices simultaneously while you’re gaming, walking around or even when something’s in the way, no strings attached. Another giant leap forward in wireless charging technology,” the company’s official handle tweeted.

It has a built-in 5-phase interface antenna, which can accurately detect the position of the device to charge it. The phase control array composed of 144 antennas can emit millimetre waves through beam-forming. Xiaomi currently owns 17 patents for the Mi Air Charge Technology. The new wireless charging tech is also capable of charging smartwatches and another wearable tech.

However, concerns were raised about the impact of this tech on the health of users.
