Air Charging Could be the Future of Smartphone Charging Technology

The future is here and air charging (over-the-air charging) could be one of the future innovations of smartphone charging technology. While air charging is not public yet and may not be seen soon, several consumer electronic companies, including phone manufacturers like Xiaomi and Motorola, have demonstrated the innovation for smartphones. However, the big question is, “can over-the-charging ever be possible?”

As technology advances, consumer electronics companies envisage a future where both power cords and wireless chargers will be obsolete. A future where smartphones – and other small devices – can automatically receive charging power over the air from a nearby “power transmitter” just like a Wi-Fi router.

This is just an envision and consumer electronics companies can dream on. In recent years, most consumer electronics companies have promised over-the-air charging while some have even presented choreographed demonstrations of their own air charging technology. However, none of them has launched an air charger yet. There is currently no charger on the market to charge smartphones remotely and it’s not clear when there will be one.

In January 2021, two popular phone manufacturers unveiled their air charging methods. Motorola unveiled its over-the-air technology for charging smartphones dubbed “Motorola One Hyper”, which raised health concerns – most people showed concern about whether this technology is harmful or not to human health. Xiaomi also introduced its brand of air charging called “Mi Air Charge Technology”, which looks like a large white power box. According to the company, Mi Air Charge Technology would enable users to charge smartphones and other electronic devices remotely without any cables or wireless charging stands. In February, Oppo, a Chinese smartphone company, demonstrated “air charging with no cables or charging stands”.

Recently, a Tokyo-based company known as Aeterlink announced “Airplug”, which it claims can power devices almost 20m away. Last year, at least four companies unveiled their over-the-air-charging concepts. While the air charging technology is not science fiction, but a real technology that can launch us into a true wireless charging era, it might always remain a dream – at least for now. According to Jake Slatnick, CEO of Aira, a wireless charging technology company, “There is no debate (concerning the over-the-air charging technology). To any sane person, over-the-air charging is the dream. It would be the most incredible experience”. Jake pointed out that “the problem is, there are too many hurdles to really make it a practical thing”.

Though most of the aspiring companies above attracted media attention, they all declared that they don’t have plans to bring the product to market for smartphones. Other companies just abandoned the air charging projects altogether. Some of the several challenges faced by companies wishing to deploy the air charging tech include physics – the farther away the smartphone is from the power source, the lower the charging efficiency would be. That means even if your smartphone receives some air charging from a distance, it might not give a meaningful amount of power. The second is the fear of radio-frequency energy that would be generated by the air-charging device. In high amounts, radio-frequency energy can interfere with other gadgets or lead to various health issues.

More so, it’s not certain that the world currently needs air charging. With the continuous improvement of smartphone battery life, air charging may not eventually make any significant impact if it ever comes to reality. Whichever, air charging could be the future of smartphone charging technology but definitely, it’s not the technology for the present.
