Introduction

At this year's autumn iPhone 15 series launch event, Apple casually mentioned that the upcoming iPhones would embrace the latest Qi2 wireless charging standard. Later, in official documentation, Apple provided detailed insights into this feature. Moreover, about seven months ago, we reported a high probability of the iPhone 15 supporting 15W Wireless Charging with Qi2.

Fast forward to December 12th, Apple surprised everyone by releasing the official version of iOS 17.2. Besides enhancing the action button and camera experiences, the most significant addition was the formal support for Qi2 chargers on the iPhone 15, 14, and 13 series. This implies that users can now enjoy a 15W wireless fast charging experience similar to MagSafe when using third-party wireless charging products certified with Qi2.

Let's briefly explore Qi2; it's a new and enhanced wireless charging standard established by the Wireless Power Consortium (WPC) in 2023. Combining Apple's MPP (Magnetic Power Profile) technology, it promises a superior wireless charging user experience and paves the way for future feature developments. ChargerLAB had previously dissected and analyzed several Qi2 certified products, including both flat and vertical designs, all equipped with fast charging modules supporting QC/PD protocols, meeting the specifications required for Qi2 MPP. Now, let's delve into the specifications and performance of the GQ22 wireless charging module.

Product Appearance

The GQ22 wireless charging module boasts an alloy shell, with a front magnetic area crafted from a smooth gray material, offering a refined feel and creating a stark contrast against the surrounding white.

Its back features a semi-open design, sporting a black region at the bottom housing metal-soldered pins, with the positive and negative pole soldering wires extending from this sample.

The length of the wireless charging module is about 59mm (2.32 inches).

The thickness is about 8.4mm (0.33 inches).

And the weight of this module is about 57g (2.01 oz).

Here's how the module looks when held in my hand, slightly larger than the Apple MagSafe charger.

Wireless Charging Test

While charging the iPhone 15 Plus with the GQ22 wireless charging module, the animation mimics that of the Apple MagSafe charger.

Additionally, its idle power consumption is approximately 0.25W.

Charging the iPhone 15 draws an input power of 8.8V 2.11A 18.61W.

Switching to the iPhone 15 Plus, the power decreases to 8.83V 1.82A 16.11W.

Charging the iPhone 15 Pro registers an input power of 8.8V 2.12A 18.68W.

For the iPhone 15 Pro Max, it's quite similar, at 8.8V 2.14A 18.82W.

Finally, let's examine the performance of the iPhone 15 when using the Apple MagSafe charger, which registers at 9.02V 2.1A 18.91W. Thus, there seems to be no significant difference between the two wireless chargers in terms of physical compatibility or charging power.

Full Charging Test

Next, we'll use it to fully charge the iPhone 15. Here is the result recorded by the PC software of KM003C.

The voltage is always around 9V. The charging curve can be divided into multiple parts. First of all, the peak power stayed at 19W from the first 9 mins. Then, the power suddenly drops to 12W, and then raises to 15W. It goes back to 12W in the 16th min. At 44th min, the power gradually drops to 7W, and raises to 13W. Next, it drops to 7.5W. The final part begins at one hour and 32 mins, and the power slowly drops to almost zero. It takes two hours and 10 mins to be fully charged.

We also turn it into another curve. The wireless charging module can charge the iPhone 15 to 50% in 44 mins. And it can reach 80% in one hour and 17 mins, 100% in two hours and 10 mins. The last 20% took nearly half the total time.

Temperature Test

We also put the module into a 25°C (77℉) thermotank throughout the test. After an hour of running, we got the maximum temperature.

At this point, using a thermal imaging camera, we noticed a peak temperature of 43.3°C (110°F) with the power around 12W. It's essential to note that this module is a semi-finished product and lacks a heat dissipation mechanism; hence, this temperature performance is considered normal.

Summary of ChargerLAB

In summary, the integration of the Qi2 protocol into the latest iPhone models marks a significant step in wireless charging technology. With Apple's endorsement of this enhanced standard, the broader market for wireless charging is poised for notable changes.

As more devices adopt the Qi2 certification, users can anticipate a more unified and enhanced wireless charging experience, fostering greater compatibility among various charging products. This move not only elevates the convenience for iPhone users but also signifies a shift toward a more standardized and efficient wireless charging landscape.
