The Wireless Power Consortium Launched the Qi2 Standard

It's not easy to charge an Android phone without magnets. The charging coil is not in the middle of the phone, so it's hard to align with the MagSafe charger. Is there another way to charge an Android phone?

The new Qi2 standard from the Wireless Power Consortium at CES 2023 solves this problem.

The cross-brand Wireless Power Consortium is responsible for formulating wireless charging specifications for electronic products. This allows Qi-format wireless charging to be applied to different products. Although Qi is now synonymous with wireless charging, it was just one of the formats in wireless charging in the early days. Qi is competing with other standards, including PMA and A4WP.

Qi2 is the first major update to Qi since Qi1.0 was released in 2010. To solve the problem of unclear charging positions in the Qi1.X version, the WPC added the Magnetic Power Profile (a map showing how much power is distributed) as the core standard of Qi2. Qi2 also has a 15W charging power.

In the future, any device marked with Qi2 can be charged with a MagSafe charger. But what about Android phones that can already charge at 100W?

Make your Android phone the icing on the cake.
Android users can be assured that supporting Qi2 will not lock your phone’s wireless charging power to 15W. Just like the PD charging standard, Qi2’s 15W is just its lower limit. It doesn’t mean that the mobile phone can only be 15W. If you want to achieve higher power wireless charging, you can develop your own charging solution.

All Android phones can do 100W wireless charging, but you need a special phone and charger. If you put the 100W MIX4 on an unsupported high-power charger, you can only get 15W.

Why does Qi2 still include MagSafe technology? Apple is a member of WPC, so the addition of MagSafe magnetic adsorption will also help the overall development of Qi2.

First, Apple says that magnetic adsorption helps users quickly find wireless charging devices. This lets mobile phones accept wireless charging more efficiently. If you've used the early Moto 360, you know how frustrating it can be to find the right place for the wireless charging base. The next Android Wear devices will use magnetic adsorption for charging, which shows how important this is for wireless charging devices.

But if we look at it another way, the addition of magnetic adsorption is just one thing that improves the charging environment. Other things, like wireless headphones or Kindles, also help.

TWS earphones have a separate charging box, so the coil is not in the centre of the product. This makes it hard for users to find the best charging position. Some users don’t know that they should put the button side down when they charge AirPods Pro.

Apple is the biggest winner

But then again, although the emergence of magnetic adsorption has improved the industry versatility of wireless charging, Apple has always been the biggest beneficiary of magnetic adsorption as the Qi2 standard.

Since Apple released MagSafe for mobile phones and earphones, MagSafe has quickly become the new favorite in the Apple ecosystem. Brands such as Belkin and Baseus have also launched a variety of MagSafe charging products in a short period of time, even making Apple’s Made for MagSafe (MFM) accessories certification system is more popular. Unfortunately, because MagSafe does not have too many technical barriers at the hardware level, as long as a few magnets are arranged, a large number of third-party brands can bypass MFM certification and launch magnetic accessories.

The entry of MagSafe into Qi2 will bring the initiative back to Apple. In the Qi2 era, since all accessories support magnetic adsorption, the selling point of MagSafe will also change from magnetic adsorption to the unique high power of MFM certification and the data transmission function that may be added in the future.

In the MFi era, the “pop-up” phenomenon that may occur when using a non-MFi-authorized data cable to charge a mobile phone, we found that even in the era when the iPhone switched to USB-C, Apple can still “exclusively” limit user charging behavior through MagSafe .
