Exploring Qi2: The Next Generation of Wireless Charging for Smartphones
What Is Qi2?
Qi2 is the latest open wireless charging standard from the Wireless Power Consortium (WPC), featuring significant improvements over the previous Qi standard. Its standout feature is the Magnetic Power Profile (MPP), which introduces magnets for precise alignment, enabling faster charging speeds. Qi2 is also backward compatible, allowing it to work with older Qi devices, enhancing its usability.
Benefits of Qi2
The advantages of Qi2 over the original Qi standard are numerous:
- Greater Efficiency: Enhanced alignment means less power loss and improved battery health.
- Faster Charging: Qi2 supports charging rates up to 15 watts, similar to MagSafe.
- Wider Compatibility: A single Qi2 charger can power both iPhone and Android devices.
Expect a Delayed Wave of Qi2 Devices
The rollout of Qi2 devices is anticipated to be gradual as manufacturers gear up for certification. While Apple's iPhone 15 supports Qi2, adoption among Android phone makers remains slow. As accessory makers develop Qi2-compatible products, consumers can expect more options in the coming years.
Explore Wireless Charging's Future
With Qi2, the goal is a universal wireless charging standard that caters to diverse devices. While some older Qi chargers may struggle with Qi2 compatibility, the push towards a unified charging solution has begun.
