Introduction
As the first Android phone to pass Qi2 wireless charging certification, the wireless charging performance of HMD Skyline is still unknown. We can also see that it supports Qi2 wireless charging on the HMD official website. ChargerLAB will conduct a wireless charging test on it below.
Product Appearance
It is equipped with a Qualcomm Snapdragon 7s Gen2 processor and a 4600 mAh battery and supports 33W wired charging, 15W Qi2 wireless charging, and 5W reverse wireless charging.
The model of the MagSafe selected for this test is A2580. Output specifications are 5V3A, 9V3A, and 15V3A.
Wireless Charging Test
HMD Skyline supports Qi2 15W wireless charging. We will use multiple wireless chargers for testing to see how compatible it is.
Charging with the Hong Kong version MagSafe, the input power is about 8.97V 1.99A 17.85W. Excluding conversion loss, the charging power is about 15W.
Charging with the Mcdodo three-in-one wireless charger, the input power is about 8.79V 2.11A 18.96W.
Charging with the UGREEN three-in-one wireless charger, the input power is about 8.96V 2.18A 19.54W.
Charging with the Anker three-in-one wireless charger, the input power is about 14.55V 1.22A 17.73W.
Charging with the Chinese version of MagSafe, the input power is about 8.97V 0.84A 7.52W.
Charging with the Xiaomi 80W wireless charger, the input power is about 8.85V 1.12A 9.94W.
Full Charging Test
We use the Hong Kong version of the MagSafe wireless magnetic charger to fully charge it. And put them into a 25°C (77℉) thermotank throughout the test.
The voltage is always around 9V. The charging curve can be divided into four parts.
In the first part, the input power was around 18W for the first 7 minutes. After that, the power dropped to 14W and 11W in turn. Finally, the power slowly drops to almost zero. It takes 2 hours and 33 minutes to be fully charged.
From this chart, it can be charged to 50% in 1 hour and 2 minutes and 80% in 1 hour and 46 minutes. It reaches 100% in 2 hours and 33 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 36.8℃ (98.24 ℉), and the wireless charger input power is about 14W.
After 20 minutes, the maximum temperature on the phone and wireless charger contact surface is 38.8℃ (101.84 ℉).
After 30 minutes, the maximum temperature on the phone and wireless charger contact surface is 38.4℃ (101.12 ℉), and the wireless charger input power is about 11W. Overall, the temperature performance is pretty good and does not exceed 40℃.
Summary of ChargerLAB
As the first Android phone certified for Qi2 wireless charging, HMD Skyline can achieve an input power of 17-20W when paired with a charger that supports the Qi2 protocol, while the input power is 7-9W when paired with a wireless charger that does not support the Qi2 protocol.
With the Hong Kong version of MagSafe, it takes 1 hour and 2 minutes to charge 50% and about 2 hours and 33 minutes to be fully charged. Most of the time, the input power is maintained at around 11W. The temperature did not exceed 40°C within 30 minutes of charging, and the temperature control performance was excellent.
