Test on 25W Apple MagSafe Charger
In September, the iPhone 16 series was launched, and the long-criticized wireless charging feature finally received a “partial” upgrade. The biggest difference with the new wireless charger compared to the old version is its braided cable, higher power output, and thinner design. Today, let’s take a look at the experience of the new MagSafe magnetic charger.
The new MagSafe wireless charger from Apple comes in the white packaging box, with the Apple logo printed in the top right corner, along with the “MagSafe Charger” text and an image of the product. The overall design is minimalist. On the back, you can find the product name, a usage diagram, and the USB-C interface. The charger has passed CE certification. On one side of the box, there is a label with the product information and specifications, indicating a length of 1 meter and the model number: A2580.
With braided cable design, the magsafe charger’s model number and power specifications are printed on the edge of the charging pad. The charger supports 3 input power levels: 5V3A, 9V3A, and 15V3A. The casing of the USB-C plug features certification marks from New Zealand (R-NZ) and Japan (VCCI). The USB-C male connector also has the MagSafe wireless charger’s model number and serial number printed on it. The internal pins of the USB-C port are not 24 pins
The iPhone 16 Pro Max supports 25W MagSafe charging, as well as Qi2 15W wireless charging and Qi 7.5W wireless charging. When paired with the MagSafe wireless charger, the output power at the charger’s end can reach 14.96V at 1.94A, delivering approximately 29.03W. After accounting for conversion losses, the wireless charging power is around 25W.
Next, we will test the performance of the iPhone 16 Pro Max paired with the MagSafe wireless charger. After completely draining the phone’s battery, we will place both the phone and the charger in a 25°C temperature-controlled chamber, connect the power, and record the data.
After connecting the power, the charger initially negotiates a 15V handshake, with power remaining stable at around 29W for the first 5 minutes. After that, the power drops to about 21W and continues charging for 31 minutes. Then, the charging power starts to decrease, and at the 39-minute mark, the voltage briefly drops from 15V to 9V. It then continues charging at 10W until the 52-minute mark. At 55 minutes, the voltage drops from 15V to 9V again, and the power decreases to 4W, charging until 1 hour and 16 minutes. After that, the voltage drops to 5V, entering a trickle charging mode, which continues until the end of the charge. The entire charging process takes approximately 2 hours and 23 minutes.
It is clear that using the MagSafe wireless charger, charging the iPhone 16 to 50% takes 34 minutes; to 80% takes 1 hour and 10 minutes; and it takes approximately 2 hours and 23 minutes to fully charge.
Conclusion
The newly launched MagSafe magnetic charger (A2580) from Apple shows significant improvements in charging power, materials, and weight. It features a braided cable that avoids the cracking and wear issues common with traditional TPE coatings, resulting in a longer lifespan. Additionally, it is thinner compared to the previous version, with the power increasing from the original 18W to 29W. Furthermore, this product continues the design of separating the power conversion circuit from the wireless charging circuit found in the old model, fundamentally isolating the heat source to reduce temperature rise, thereby enhancing the user experience.
According to actual measurements with the iPhone 16 Pro Max using the MagSafe charger, it can maintain a wireless charging power of 21-29W for 31 minutes. The phone is nearly fully charged after 1 hour and 37 minutes, with the remaining time spent in trickle charging. The total time to go from 0% to 100% is about 2 hours and 23 minutes, which is similar to the wireless charging data of previous models. In terms of charging temperature, the 25W MagSafe wireless charger maintains a temperature of around 39.3-41.2℃ within 50 minutes. It can still feel a bit warm to the touch, indicating that further optimization is needed for heat generation during charging.
Get up to 25W faster wireless charging
The MagSafe Charger is designed to quickly and safely wirelessly charge your iPhone. The system intelligently adapts to conditions to optimize charging your iPhone at up to 25W of peak power delivery for faster wireless charging. The actual power delivered to the iPhone will vary depending on the iPhone model, wattage of the power adapter, and system conditions.
It’s important to plug into a power source before placing your iPhone on the MagSafe Charger. This allows MagSafe to verify it’s safe to deliver maximum power. If you happen to place your iPhone on the MagSafe Charger before plugging into a power source, simply remove your iPhone from the MagSafe Charger, wait three seconds, and then put it back on to resume maximum power delivery.
All power adapters have different ratings for amount and rate of power delivery. The MagSafe Charger requires the following ratings to deliver faster wireless charging.
Compatible Power Adapters and iPhone Models for Up to 25W Faster Wireless Charging
- Models: iPhone 16 Plus and iPhone 16 Pro Max
- Power Requirements:
- Use a power adapter rated at 30W or higher.
- A power adapter providing 15V/2.0A or more is required.
- MagSafe Charger with part numbers A2580 or A3250 is also compatible.
Using higher-wattage adapters rated at or above 15V/2.0A can deliver a peak power of up to 25W to your iPhone. The iPhone 16 and iPhone 16 Pro can achieve a peak power of 22.5W.
Compatible Power Adapters for Up to 15W Faster Wireless Charging
- Models: iPhone 15 and earlier
- Power Requirements:
- A USB-C power adapter rated at 20W or more is needed.
- Adapters providing 9V/2.22A or 9V/2.56A or higher are suitable.
For the iPhone 13 mini and iPhone 12 mini, you can achieve up to 12W for faster wireless charging with a minimum of 9V/2.03A. Adapters rated at 9V/2.56A or above can also deliver a peak power of up to 15W to your iPhone*.
When using the MagSafe Charger, the iPhone 13 mini and iPhone 12 mini can receive up to 12W of peak power delivery. However, when Lightning accessories like headphones are connected, charging is capped at 7.5W to meet regulatory standards.
