Introduction

In September, the iPhone 16 series was released, along with the new MagSafe that can support 25W. The appearance has not changed much; it is thinner and lighter, and the cable has been replaced with a woven cable. Next, let's take a look at its charging performance.

Product Appearance

It comes in a white box with the Apple logo and product appearance.

There is a product usage diagram printed on the back, and it has passed CE certification.

The specs info is posted on the bottom of the box: length 1m, model: A2580.

The box contains the MagSafe charger and some documents. It uses a woven cable, and the magnetic module is smaller and thinner.

It can support input of 5V3A, 9V3A, and 15V3A.

The USB-C connector is printed with New Zealand R-NZ and Japan VCCI certification logos.

The model and serial number information is printed here.

It adopts the non-full pin design.

A close look at the woven cable.

The length is about 104 cm (3' 4.94'').

The diameter of the wireless charging panel is about 55.38 mm (2.18 inches).

The thickness is about 4.53 mm (0.18 inches).

The wire diameter is about 2.35 mm (0.093 inches).

The weight is about 46.1 g (1.63 oz).

The left side is the old MagSafe (A2140), and the right side is the new 25W MagSafe (A2580). They are the same in appearance; the main difference is the cable material.

The top one is the new 25W MagSafe, and the bottom one is the old MagSafe.

The new 25W MagSafe is thinner than the old MagSafe.

Wireless Charging Test

In addition to supporting 25W MagSafe charging, the iPhone 16 Pro Max also supports Qi2 15W wireless charging and Qi 7.5W wireless charging.

Using an Apple 30W charger and the new MagSafe Charger to charge the iPhone 16 Pro Max, the measured input power is about 14.96V 1.94A 29.03W. Excluding losses, the wireless charging power is about 25W.

Full Charging Test

Next, we'll use the MagSafe Charger with an Apple 30W charger to fully charge the iPhone 16 Pro Max. And put them into a 25°C (77℉) thermotank throughout the test.

The voltage is around 15V at first, and the charging curve can be divided into five parts. In the first part, the peak power stays at 29W for the first 5 minutes. Then, the power gradually drops to 21W, 10W, and 4W in turn. At 39 minutes, the voltage drops from 15 V to 9 V briefly and then increases to 15 V. At 55 minutes, the voltage drops from 15 V to 9 V. The final part begins at one hour and 16 minutes; the power slowly drops to almost zero. During this process, the voltage drops to 5V. It takes 2 hours and 23 minutes to be fully charged.

We also turn it into another curve. The new MagSafe Charger can charge the iPhone 16 Pro Max to 50% in 34 minutes. And it can reach 80% in 1 hour and 10 minutes and 100% in 2 hours and 23 minutes.

Temperature Test

Since wireless charging generates a lot of heat, temperature is something everyone is concerned about. So, we recorded the highest temperature on the front and back after charging for 15 mins, 30 mins, and 50 mins.

After 15 mins of charging, the maximum temperature of the contact surface between the phone and the wireless charger is 41.2℃ (106.16 ℉). At this time, the charging power is about 21W.

After 30 mins of charging, the maximum temperature is 39.4℃ (102.92 ℉).

After 50 mins of charging, the maximum temperature is 39.3℃ (102.74 ℉). At this time, the charging power is about 10W. Compared with the temperature at the 15th minute, the temperature dropped by about 1.9°C, but it was still relatively high.

Summary of ChargerLAB

The new 25W MagSafe uses a woven cable, which is more durable. Compared to the old model, it is thinner.

Within 31 minutes, the new MagSafe Charger can maintain a charging power of 21 to 29W. The full charging time is 2 hours and 23 minutes, which is similar to the previous generation. As for the temperature, it was maintained at 39.3-41.2°C within 50 minutes. It’s similar to other magnetic wireless chargers, but it has higher power, so it performs well.
