Apple still working on AirPower-esque charger, investigating long-distance wireless chargi...

Some four years after Apple publicly unveiled its vision of free-placement wireless charging in AirPower -- and two years after the device was cancelled -- the company is reportedly continuing work to bring the technology to market.

AirPower


In a report covering fresh iPad rumors, Bloomberg on Thursday said Apple is still working on a wireless charging device capable of simultaneously delivering power to iPhone, AirPods and Apple Watch.

Specifics are unknown, with sources saying only that the charger would operate "similarly" to AirPower.

Announced in 2017, AirPower was Apple's attempt at creating a charging mat that served its entire mobile device ecosystem. The project was ultimately cancelled in 2019 after suffering multiple delays, with later reports claiming Apple was unable to overcome issues related to overheating.

Rumors of a revival surfaced in 2020 on claims that advanced power management would address the overheating problems, but the project was reportedly shelved some ten months later.

Apple began to file and receive patent grants for technology that would underpin a device like AirPower around the time the device was unveiled. Those filings continue to trickle out, with the latest grant issued on Tuesday.

Apple is also researching wireless charging technology that works at greater distances than modern inductive charging solutions like Qi and its own Apple Watch system, Bloomberg reports. The tech could be based on a long and diverse string of patents covering long-range wireless charging methods, the earliest of which date back nearly a decade.

Development of the system appears to be ongoing, as the report says it will likely take several years for the effort to result in a shipping product if Apple chooses to move forward with the initiative.

Apple's next-generation iPad Pro might be the company's first tablet to support wireless charging, a feat that could be accomplished by adopting a "glass sandwich" design. A redesigned iPad mini is also expected to debut later this year.

iPad Pro


Citing sources familiar with Apple's plans, Bloomberg on Thursday reports the company is working to integrate wireless charging capabilities into its tablets, a product line that saw explosive growth over the past year as the coronavirus pandemic spurred a work from home boom.

To facilitate wireless charging, Apple is reportedly mulling a glass back design for 2022 that would bring iPad Pro's aesthetics in line with recent iPhone models. A magnetic wireless charging system similar to MagSafe is also in the works, though -- like MagSafe on iPhone -- the system is unlikely to deliver charge rates that rival a cabled setup.

Specifics of the solution went unreported, but Apple could be experimenting with high output wireless power technology that trumps MagSafe's 15W fast charge limit. The company in 2017 acquired a New Zealand startup called PowerbyProxi, which marketed a product capable of delivering 100 watts of wireless power with a 65mm coil. As it stands, iPad's capacious batteries are juiced up via USB-C or Lightning. The report notes that Thunderbolt will continue to see use on next-generation iPad Pro models.

Apple is also developing so-called reverse charging, or "bilateral" charging, capabilities for its top-end tablet hardware.

Initially rumored to debut on iPhone in 2019, reverse charging would enable users to charge a second device, like AirPods or perhaps an iPhone, using iPad Pro's internal charging coils. It was previously reported that both iPhone 11 and iPhone 12 include the circuitry requisite to support such a feature, though it was never activated.

Interestingly, Bloomberg suggests reverse charging on iPad Pro might be compatible with Apple Watch, a device that uses a proprietary charging protocol instead of Qi-based technology employed by iPhone, AirPods and other Apple devices.

The publication tempers expectations by cautioning that Apple's iPad Pro plans could change or be nixed before an expected launch in 2022.

As for iPad mini, the report claims Apple is testing a redesign that incorporates narrow display borders and removes the tablet's home button in favor of an "all-screen" configuration. The company could unveil the device alongside a thinner education-focused iPad as early as this year.

The rumor matches predictions from analyst Ming-Chi Kuo, who in a report published more than a year ago forecast the 2021 launch of a home button-less iPad mini. Kuo expects the diminutive tablet to sport a display measuring between 8.5 inches and 9 inches on the diagonal, specifications echoed in supply chain rumblings in January.

    I think the longer range wireless charging option might not be several years off.

    From what I've seen from other companies, a solution may be fairly close to coming to market. That one uses a ceiling mounted laser to feed energy into devices simultaneously.

    The reverse charging aspect should have been on iPhones years ago but the insistence on skimping on battery capacity probably made it unwise to implement.

    Reverse wired charging is excellent for things like wireless earbuds but I don't know if iPhones have that capacity.

    Electric vehicles will be able to reverse charge many products beyond (probably other cars too).

    While Apple is not always on the bleeding edge of features and specs (and for good reason), I do think reverse wireless charging for things like the watch and AirPods is a feature long overdue.  Samsung has had this for years.

    Skimping??? How else do you suppose they make the phones ridiculously thin, that is *the* most important feature after all. /s

    Apple is ALWAYS on the bleeding edge. People like to conveniently nit-pick gimmicky trends from the knockoffs to say Apple isn’t innovative.

    A few bleeding edge products and features:
    iPhone
    Apple Watch
    AirPods
    Apple Card
    Spacial Audio
    TrueDepth Camera
    Attention Correction
    All Apple Watch sensors

    That is not how I intended my comment to be interpreted. When I say not on the bleeding edge in terms of specs and features, I mean things like amount of RAM, megapixels, various features like wireless charging and water resistance etc.  I agree that sometimes these things are gimmicky and Apple is wise not to jump on board all the time.  Apple does not “spec whore,” is what I’m saying.  That being said, I think it’s time for reverse charging.

    If Apple were ALWAYS on the bleeding edge then you could've listed all Apple products at any point in time.  That's clearly ludicrous, Apple often let product lines languish without updates while they concentrate on other things.  The MacBook Air, Mac mini and Mac Pro have had recent, widely noted, very long periods of little attention, being very far from the bleeding edge.  And lots of products, many apps, many entry level devices have never been bleeding edge.

    Your claim is nonsense Apple fantard-ism.
