Apple Still Working to Perfect Wireless Charging Technology for 'iPhone 8'

The U.S. Patent and Trademark Office published a patent application from Apple today that details how new brushing and polishing tools could be used to finish a wireless charging station.

While the application covers general polishing techniques for cylindrical and contoured surfaces, Patently Apple notes that the patent also details ways to create a space for an inductive charging coil, confirming that the tools are designed specifically for the creation of a wireless charging device.

In describing how the tools would work, the application includes multiple illustrations of a charging station used to provide electrical current to another device via inductive power transmission. An inductive transmitter coil wraps around a metal core and is designed to pair with a receiver coil and charge the battery in the electronic device.

Apple notes that the charging station could include an electromagnetically transparent support surface for the device to be charged, allowing it to sit on the station unencumbered and receive power wirelessly via the induction coupling technology. The charging station is also described as including a port for a USB-type connector cable to connect with an external power source, such as a laptop.

The patent application was filed in late 2015, and provides ample evidence that Apple's engineering teams continue to investigate wireless charging solutions. Indeed, Apple has had an interest in the technology ever since the first iPhone, gaining patents for wireless charging stations and wireless charging via near field magnetic resonance, which wirelessly charges a device within a certain region.

Earlier this year, one rumor source suggested the iPhone 7 would feature wireless charging as well as better waterproofing and no headphone jack. However, that report warned that the charging feature could be pulled from the iPhone 7 for a future iteration of the device, since Apple was still working on the technology.

Indeed, only two of the aforementioned features were ultimately realized this week, indicating Apple may have purposely held back the charging technology in order for it to be included in its tenth anniversary "iPhone 8", said to be debuting next year.

The suggestion will undoubtedly grate for some readers, given that this would have been the perfect solution for charging an iPhone and listening to music through wired headphones at the same time, rather than using the more cumbersome charging dock method suggested by Apple marketing chief Phil Schiller.

Back in September 2012, however, Schiller said that Apple wasn't sure of how convenient the then-current state of wireless charging technology was, since most wireless charging systems had to be plugged into a wall. This may explain why Apple is still exploring the technology. Indeed, the company has shown an interest in WiTricity's wireless charging tech, which uses a "hidden charging" method that allows magnetic fields to wrap around barriers, which would allow users to place their charging pads wherever they want.

Wireless charging would be nice for me so I can eliminate the cords at my bedside that the cats like to chew on. :p


How do you get rid of the wires, since the charging unit has to be plugged in?

I wish they fixed less on brushing and polishing and more on technology.


Huh? iPhone is jam packed.

I'd bet my bottom dollar that this'll be in the 2018 model. 2017 one is going to be the 7S with full waterproofing.

You mean like those A-series CPUs that completely spank the competition?

i'm not sure i'd want a wireless charger next to my head while sleeping..

I don't see how it would be much different than having a cell phone or wifi device in the same room. Radio waves are everywhere, from AM/FM, TV, WiFi, BT, cellular, HF, UHF, VHF, public safety systems, and so forth.

Jam packed with what, a battery?

Windows phones can connect to a monitor and keyboard and serve as a kind of a desktop replacement, Samsung phones have edge to edge screen, Huawei dual camera phones have refocusing and not just a blurred background "coming later this year" (HTC had this feature first in 2014). Not to mention better water resistance in some of those and an audio jack (and some support a memory card, dual SIM etc etc).

The best thing about new iPhone is the processor, it's crazy powerful but what't the point really. Heavy gamers are the ones who need it. With all that power and money and human resources we could have a much better phone. The vision is lacking.


Are you serious lol

If wireless charging requires the iPhone to physically contact some kind of 'puck' then it won't help in many of the situations where people might want to use their phone whilst charging and using headphones ie watching a movie at night, playing games etc...

I also worry that you will need charging pucks everywhere, one by the bed, one on your desk, one in the car etc...

I've seen several people make that request... full waterproofing. What exactly are you asking? A higher level of water resistance? That would be nice. There will never be a 100% waterproof phone. It's always going to be a level of water resistance. Just like watches. Simplest reason: waterproof implies legal liability.


Except Samsung Exynos 8890 CPUs, If LG decided to use the Apple Ax CPUs on one of their smartphones running android, the performance will be...well you know the resto_O

I think we do know the rest. The Ax series on Android would most likely perform just like Samsung's Exynos and Qualcomm's Snapdragon. Apple's software/hardware integration can't be understated. It contributes to the performance of the Ax series.
