Introduction

Recently, Apple officially introduced that the iPhone 15 series now supports the Qi2 wireless charging standard. This means you can use the Qi2 charge to charge your iPhone, even without the MFM certification. It can output at 15W just like the MagSafe.

Qi2 Wireless Charging

Qi2 is the new generation wireless charging standard introduced by the Wireless Power Consortium (WPC).

The standard incorporates the Magnetic Power Profile (MPP) technology based on Apple's MagSafe technology. It aims to provide a better wireless charging user experience and pave the way for the development of new features and enhanced functionalities.

On December 12, Apple released iOS 17.2, adding Qi2 support to the iPhone 13 and 14 series.

Power Test

ChargerLAB has taken apart a few chargers with the Qi2. These chargers all support the QC/PD protocol and can meet the requirements of Qi2 MPP.

Use the NuVolta Qi2 MPP Module to charge the iPhone 15 which is updated to iOS 17.2. The charging UI is the same as the original MagSafe charger. And the output power is about 8.91V 2.22A 19.75W.

Use the Apple MagSafe charger to charge the phone. The output power is about 9.02V 2.1A 18.91W. The power of these two chargers is almost the same.

Full Charging Test

Next, we’ll fully charge the iPhone 15 with the Apple MagSafe.

The voltage is always around 9V. The charging curve can be divided into four parts. In the first part, the peak power stayed at 18.7W for the first 10 mins. Then, the power gradually drops to 13W and 7.6W in turn. The final part begins at one hour and 23 mins, and the power slowly drops to almost zero. It takes two hours and 10 mins to be fully charged.

Move to the NuVolta Qi2 MPP Module.

The voltage is always around 9V. The charging curve can be divided into seven parts. In the first part, the peak power stayed at 19.5W for the first 9 mins. Then, the power gradually drops to 14W and 12W in turn. And the power rises to 15W at 46 mins. After that, the power gradually drops to 13W, 8W in turn. The final part begins at one hour and 32 mins, and the power slowly drops to almost zero. It takes two hours and 2 mins to be fully charged.

Temperature Test

Next, we put the Qi2 MPP wireless charger and iPhone 15 into a 25°C (75℉) thermotank throughout the temperature test.

After one hour of charging, the maximum temperature is 42.9 ℃ (109.22 ℉). Because the Qi2 MPP wireless charger does not have a casing, the temperature measured is the PCB, so the temperature is higher than that of the original MagSafe.

Summary of ChargerLAB

After upgrading to iOS 17.2, the Qi2 wireless charging power of the iPhone 15 series is basically the same as that of the original MagSafe charger. With Apple opening up MPP, disruptive wireless charging products may appear again.
