Apple looks at a wireless charging future

The hardware never reached retail stores. Apple delayed the mat past its initial target window and provided minimal public comment on its development status for a long stretch.

Cancellation followed in March 2019. Dan Riccio, then Apple's senior vice president of hardware engineering, confirmed the project was dead. Riccio stated that after much effort, the company had concluded the product would not achieve its high standards. The statement closed the book on the mat, leaving Apple without a branded multi-device inductive pad.

The engineering difficulty stemmed from building a flat surface that could charge multiple devices regardless of where a user set them down. Traditional inductive charging demands that the transmission coil in the base align closely with the receiving coil inside the handset. To remove that requirement, a mat has to pack overlapping coils across its entire surface area. When several coils operate in close proximity inside a slim enclosure, electrical interference and heat accumulation multiply rapidly. Apple chose to cancel the physical product entirely rather than release hardware that failed to meet its operating criteria.

The failure of the mat forced a fundamental rethink of wireless power delivery. Attempting to make an entire surface active was inefficient. The alternative was to guarantee that the single primary coil in the charger and the single receiving coil in the phone physically found each other every time.

What MagSafe turned into

Apple's pivot away from flat mats became clear when the company introduced magnetic attachment hardware, branding the mechanism as MagSafe. Instead of asking users to search for an invisible induction sweet spot on a flat desk puck, a ring of integrated magnets pulled the accessory directly into place.

The scope of that design broadened dramatically in January 2023. The Wireless Power Consortium announced the Qi2 standard, confirming that Apple had provided the foundational basis for the new industry specification by building on its MagSafe technology.

The Consortium stated that Apple and other Consortium members developed the Magnetic Power Profile, which sits at the center of the Qi2 standard. This was not a licensing deal where third-party manufacturers paid Apple for proprietary magnetic rings. It was an incorporation of Apple's mechanical architecture directly into an open global specification administered by the Consortium.

The decision changed how the wider consumer electronics industry approached inductive hardware. Under earlier iterations of the Qi specification, non-magnetic chargers were common across the market. Devices frequently slid off center when bumped or vibrated, interrupting power flow during the night. By submitting its magnetic design work to the Wireless Power Consortium, Apple helped establish a universal hardware baseline that any certified manufacturer could adopt. MagSafe transitioned from a proprietary hardware feature into the structural framework for the next generation of open wireless power.

Magnetic alignment as a standard rather than a feature

The Wireless Power Consortium gave a direct technical explanation for building Qi2 around magnetic hardware: magnetic alignment of the device and the charger improves both efficiency and charging speed.

Inductive charging functions through electromagnetic fields generated between two copper coils. When the transmitter coil in the charger sits off-center from the receiver coil inside the phone, the magnetic coupling weakens. This misalignment wastes electrical energy, converting power directly into heat instead of transferring it to the battery cells. Excess thermal buildup forces charging controllers to throttle current, which lengthens the time required to complete a charge.

The Magnetic Power Profile eliminates physical misalignment. When a Qi2-certified device approaches a Qi2-certified charger, the magnetic ring forces the two coils into direct, concentric alignment.

Standardising that alignment within the Wireless Power Consortium matters far more than any individual accessory release. When alignment remains a proprietary feature, accessory makers must develop separate product lines for different hardware ecosystems or rely on loose mechanical cradles that only fit specific phone dimensions. Standardising the ring geometry creates universal mechanical interoperability across the market.

A certified Qi2 desk stand, car mount, or battery pack locks onto any certified phone with identical physical positioning. The specification guarantees that every certified peripheral establishes the precise spatial tolerance required for optimal energy transfer. Magnetic coupling stopped being an optional marketing perk and became an enforced engineering requirement for power delivery.

What the 25-watt tier changed and what it did not

The standard took another step forward in July 2025, when the Wireless Power Consortium adopted an updated specification designated as Qi v2.2.1 and branded commercially as Qi2 25W.

The primary technical update in Qi v2.2.1 was an increase in the maximum charging ceiling. Compatible devices operating under the Qi2 25W tier can charge at 25 watts, whereas earlier versions of the standard were limited to 15 watts. The update increased the power delivery ceiling by 10 watts, bringing wireless charging speeds closer to standard wired wall adapters.

The July 2025 adoption also expanded the hardware footprint of the standard. Major Android smartphones joined the Qi2 ecosystem for the first time alongside the launch of Qi2 25W. What had originated as Apple's proprietary MagSafe design became an active charging standard across competing flagship Android devices.

The 25-watt tier establishes higher power capabilities across the market, but it does not standardize how individual devices handle that power once it enters the receiver. The Wireless Power Consortium specification sets the rules for the physical Magnetic Power Profile, the communication handshake between transmitter and receiver, and the electrical capability to push and receive up to 25 watts. It does not dictate how an individual phone manufacturer manages battery charging curves, device temperatures, or thermal throttling.

A handset maker retains full authority over its internal power management controllers. A device might accept the maximum 25 watts when the battery sits at a low charge level in a cool room, but taper the intake rate downward as internal temperatures rise or as the battery approaches full capacity. The standard governs the connection, the alignment, and the maximum power delivery ceiling across the magnetic interface; the individual handset maintains absolute control over what happens to the power once it arrives.
