Apple’s adoption of Qi wireless charging spurs development

“The competition among wireless charging standards did not come to an end when Apple decided to choose Qi of the WPC (Wireless Power Consortium) for iPhone X and iPhone 8 devices in 2017,” Osiris Hu reports for Digitimes. “Instead, the move has pushed the member companies in the AFA (AirFuel Alliance) to exert efforts to develop magnetic resonance (MR) and other RF wireless charging solutions in order to win a new round of battle in the mid- and long-distance wireless charging segment, according to Digitimes Research.”

“Digitimes Research considers it a calculated move of Apple to usher in 7.5W wireless charging technology following the release of iOS 11.2,” Hu reports. “It is conservative as compared to the over 15W charging capacity of readily available wireless charging boards, but it is a rather bold step ahead compared to the mainstream 5W wireless charging technology used by most other smartphone models.”

“Although magnetic induction is currently the mainstream technology for the development of wireless charging, this technology still has a number of drawbacks,” Hu reports. “For this reason, makers in the field are still developing multiple technologies for wireless charging, including the use of magnetic resonance, ultrasound, infrared, electromagnetic waves, radio frequency, and solar energy, making the development of rapid charging technology a focus of attention.”

  1. How about kinetic charging, similar to Seiko Kinetic watches for keeping your watch batteries charged throughout the day. Or airpods, or anything else you wear? Even augment your cell phone charging with like technology. That way I won’t need to plug my phone in multiple times every day. As long as I am moving around, my device is charging.

    1. That’s enough to keep a simple watch running, but it’s not going to create enough power to have a meaningful impact on a phone’s charging requirements. You could put it in a paint mixer and shake it up all day and it probably wouldn’t stop you needing to plug it in.

  2. Did I read somewhere that if you’re using your phone whilst it’s qi charging it’s still running off the battery (as opposed to when you plug it in where it runs off the wired power directly). Personally, I find that with qi I’m more tethered than when I’m plugged in with a decent length cable.

    1. Current wireless charging technologies (and, yes, MDN, they are “true” wireless charging systems) are intended to enable you to set down your phone and have it charge while you are doing something else. The objective is to make it easier and more convenient to keep it charged up so that you do not need to charge it while using it.
