15W without MFM Certification! Charging iPhone 15 with Qi2 Wireless Charger (iOS 17.1)

Introduction

About half a year ago, we reported that Apple iPhone 15 continues to support 15W wireless fast charging, and it can be compatible with the Qi2 standard. When the iPhone 15 series was released, Apple confirmed this, which means we can possibly enjoy a similar wireless fast charging experience to MagSafe at a lower accessory price.

Last week, ChargerLAB discovered that the latest version of iOS 17.1 officially supports MPP 15W. For this, we immediately reached out to Anker, a top accessory brand that launched several MPP wireless charging products during IFA 2023. They provided us with their new products that support this feature for testing, so let's take a look!

First, let's briefly review the Qi2 standard.

Qi2 Wireless Charging Introduction

Qi2 is a new and enhanced wireless charging standard established by the WPC (Wireless Power Consortium) in 2023. It incorporates Apple's MPP (Magnetic Power Profile) technology, aiming to provide users with a better wireless charging experience and pave the way for the development of new features and enhanced functionality in the future.

The most significant difference Qi2 brings to users is that wireless charging devices certified by Qi2 can provide a 15W charging experience to supported devices. WPC believes that Qi2 will be a significant business opportunity in 2023/2024.

Test

During IFA 2023, top accessory brands like Anker introduced several new Qi2 products, including the 3-in-1 wireless charger and magnetic power bank, which we are going to showcase today. These products are not yet on the market and do not have official names. So we will only provide a simple introduction.

The Anker 3-in-1 wireless charger consists of two charging pads, with each one marked with the Qi2 logo. When not in use, you can fold it for easy portability.

You can see that the wireless charging UI for the phone is consistent with the original MagSafe when using the Anker 3-in-1 wireless charger to charge the iPhone 15. At this point, the ChargerLAB POWER-Z KM003C shows a charger output power of 14.97V 1.3A 19.51W.

In addition, its standby power consumption is 0.78W.

The Anker magnetic power bank is quite similar to the previous one and has only one charging area.

When folded, it is very similar to a common MagSafe battery pack, making it suitable for both outdoor and indoor use.

Similarly, it has an official charging UI, and the charger's output power is also around 19.5W.

Standby power consumption is reduced to 0.32W.

In terms of charger output power, the Anker 3-in-1 wireless charger is on par with Apple's MagSafe, which is quite remarkable for a non-MFM certified third-party product.

Full Charging Test

Next is the full charging test. We placed the magnetic power bank with a zero charge iPhone 15 in a constant temperature chamber at 25°C and recorded the data. (Note: 1. The vertical axis represents the charger's output power; 2. The charger's 20W output corresponds to 15W wireless charging.)

The voltage is around 15V throughout the test, and the charging curve can be divided into seven parts. In the first part, the peak power stayed around 20W for the first 7 mins. Then, the power gradually drops to 16W, 14W in turn. Then, the power fluctuated around 10W till one hour and 27 mins. Next, the power dropped to 8.6W and stayed there till one hour and 52 mins. Finally, the power slowly drops to almost zero. It takes two hours and 3 mins to be fully charged.

Now, let's see how the 3-in-1 wireless charger performs.

The voltage is around 9V throughout the test, and the charging curve is actually quite similar to the last one. At first, the peak power stayed around 20W for the first 10 mins. Then, the power gradually drops to 15W, 12W in turn. Then, unlike the magnetic power bank, the power stayed around 10W till one hour and 20 mins. Next, the power dropped to 8W and stayed there till one hour and 44 mins. Finally, the power slowly drops to almost zero. It takes two hours and 5 mins to be fully charged.

Finally, let's compare it with the MagSafe charger.

The voltage is always around 9V, and the charging curve can be divided into four parts. In the first part, the power stayed around 18.7W for the first 10 mins. Then, the power fluctuated while dropping to 13W. Next, the power dropped to 7.6W and stayed there till one hour and 23 mins. Finally, the power slowly drops to almost zero. It takes two hours and 10 mins to be fully charged.

When we plot the data from the three tests on a line graph, we can see that Anker's two new products offer a faster full charging time compared to Apple's MagSafe, providing a great experience.

Summary of ChargerLAB

In summary, just two months after the release of the new iPhone 15 series, Apple has fulfilled its promise to add Qi2 compatibility to its devices. Based on our test, wireless chargers that support the Qi2 standard provide a similar experience to the original MagSafe charger. That means we'll be able to enjoy the same 15W fast charging experience as MagSafe at a lower price. Pretty sweet.
