Apple developing iPad Pro with glass back and MagSafe, home button-less iPad mini

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.
