Introduction
Previously, ChargerLAB tested the wired charging of Xiaomi 15 Pro, and its built-in 6100mAh battery can be fully charged in 53 minutes with the support of 90W fast charging. This time, we will test the wireless charging of Xiaomi 15 Pro.
Product Appearance
Xiaomi 15 Pro has a 6.73-inch 2K low-power screen with a pixel density of 522PPI, an adaptive refresh rate of 1-120Hz, a resolution of 3200*1440, a peak brightness of 3200nits, covers 100% P3 wide color gamut, and supports 3D ultrasonic fingerprint, DC-like dimming, and 1920Hz high-frequency PWM dimming.
It is equipped with three Leica large-aperture lenses that cover focal lengths from 14mm to 120mm, making it versatile for various styles, from portraits to landscapes. The main camera has an impressive ƒ/1.44 aperture, allowing more light, faster shutter speeds, and natural background blur. This creates an enhanced "main character" effect in portrait shots and emphasizes subjects in stills.
From left to right, at the bottom are the speaker opening, USB-C charging port, microphone opening, and SIM card slot. The USB-C port supports USB 3.2Gen2 transmission specifications and theoretically supports up to 10Gbps.
Wireless Charging Test
We will use multiple wireless chargers for testing to see how compatible it is.
Charging with the Xiaomi 80W Adaptive Wireless Charging Stand, the input power is about 17.10V 2.96A 50.62W, which is in line with the advertised 50W wireless charging power.
Charging with the Xiaomi 80W air-cooled wireless charging stand, the input power is about 20.05V 2.56A 51.42W, which is in line with the advertised 50W wireless charging power.
Charging with the Chinese version of MagSafe, the input power is about 8.97V 0.73A 6.51W.
Charging with the Hong Kong version MagSafe, the input power is about 8.97V 0.69A 6.21W.
Charging with the charger that supports the qi protocol, excluding losses, the power is limited to about 5W.
Full Charging Test
We use the Xiaomi 80W Adaptive Wireless Charging Stand (model: MDY-16-E) to fully charge it. And put them into a 25°C (77℉) thermotank throughout the test.
At first, the voltage is around 17V. The charging curve can be divided into five parts. In the first part, the power was around 51W for the first 3 minutes. Then, the power gradually drops to 26W. After that, the power rises to 35W. At about 1 hour and 1 minute, the phone displays that the battery is fully charged, but charging is still ongoing, and the voltage drops from 17V to 10V. It takes 1 hour and 25 minutes to be fully charged.
From this chart, it can be charged to 50% in 29 minutes and 80% in 48 minutes. It reaches 100% in 1 hour and 25 minutes.
Temperature Test
We also recorded the highest temperature after charging for 10 minutes, 20 minutes, and 30 minutes.
After 10 minutes, the maximum temperature on the phone and wireless charger contact surface is 36.6℃ (97.88 ℉).
After 20 minutes, the maximum temperature is 37.4℃ (99.32 ℉).
After 30 minutes, the maximum temperature is 37.7℃ (99.86 ℉). Within 30 minutes, the power was between 35 and 51W, and the temperature was controlled at 36.6-37.7℃. The temperature control is very good.
Summary of ChargerLAB
Using Xiaomi's high-power wireless charger can achieve the officially advertised 50W wireless fast charging. With the Xiaomi 80W Adaptive Wireless Charging Stand, it takes 29 minutes to charge 50% and about 1 hour and 25 minutes to be fully charged. Within 30 minutes, the power was between 35 and 51W, and the temperature was controlled at 36.6-37.7℃. The temperature control is very good. In general, Xiaomi 15 Pro wireless charging has good adaptability to the original wireless charging and has a very good experience in charging speed, power, and temperature, while third-party chargers will greatly reduce the wireless charging experience.
