Apple’s MagSafe: From iPhone feature to industry standard
Apple’s MagSafe technology, introduced with the iPhone 12, combined wireless charging with a magnetic attachment system that made it easier to align devices and accessories.
The iPhone 12 launched with 5G and brought Apple’s flat-edged industrial design to the iPhone lineup.
But MagSafe was one of its notable additions, turning what had previously been a simple wireless charging system into a broader platform for accessories, according to a Forbes report.
Apple had been relatively late to wireless charging. The company announced its AirPower charging mat but never released it, eventually adopting the Qi wireless charging standard, which offered compatibility with a wide range of accessories.
Wireless charging using Qi still required users to correctly align the induction coils in the phone and charger so that power could be transferred efficiently.
Apple sought to simplify that process by combining the Qi charging system with a ring of magnets built into the back of the iPhone.
The magnets automatically aligned the charging coils, eliminating the need for users to repeatedly adjust the phone on the charging pad.
The system later enabled charging at Qi2’s higher 15-watt rate.
Apple also incorporated near-field communication (NFC) into the charging system, allowing compatible accessories to be detected when placed near the iPhone and enabling background connectivity between the devices.
Rather than describing MagSafe simply as a charging system, Apple presented it as a modular platform for accessories.
The technology initially included proprietary elements that required accessory makers to license parts of the MagSafe system from Apple.
However, Apple later contributed its magnetic alignment technology to the Wireless Power Consortium for inclusion in the Qi2 standard.
That move expanded the technology beyond the iPhone and allowed compatible Android phones and other devices to use the same basic magnetic alignment approach.
Magnetic accessory systems based on the technology have since become common across smartphones and related devices.
They are used for a range of products, including battery packs, desktop stands, credit card wallets and camera accessories.
In effect, Apple developed the magnetic alignment system to address a problem with wireless charging on its own devices before contributing the technology to an industry standard that allowed it to be used more broadly.
