Introduction
HMD Global Oy is a Finnish company that acquired the Nokia brand license in 2016 and focuses on designing, developing, producing, and selling Nokia-branded mobile devices such as smartphones. It adheres to the core concepts of durability, fun, security, speed, and affordability, and strives to create products with multiple advantages. In Finland, HMD launched the first batch of Nokia devices, and since then, the product line has been continuously expanded to include classic models, such as the Nokia 8110 replica that reproduces the classic charm of the past.
The front design of HMD Skyline pays tribute to the Nokia N9. It is equipped with a Qualcomm Snapdragon 7s Gen2 processor, a 4600 mAh battery, and supports 33W wired charging, 15W Qi2 wireless charging, and 5W reverse wireless charging. Next, let's take a look at its actual charging performance.
Product Appearance
The front of the box is printed with a rendering of the back of the phone, with HMD and SKYLINE printed on it.
The back is printed with information such as product configuration.
The box contains the HMD Skyline, a dual USB-C cable, and some documents.
It is equipped with a Qualcomm Snapdragon 7s Gen 2 processor using a 4nm process. The CPU consists of four 2.4GHz A78s and four 1.95GHz A55s, which can meet the daily needs of most users. It is available in two versions: 8GB+128GB and 12GB+256GB and also supports microSD card expansion.
The design on the front pays tribute to the Nokia N9, with a right-angle frame and chamfered screen edges similar to the Nokia Lumia 830. The frame is similar to the thick metal frame of the Lumia 925, and the thickness is comparable to the Lumia 920, which is full of nostalgia for old Nokia users.
It also has a 6.55-inch OLED screen with a resolution of 1080*2400, a pixel density of approximately 402ppi, a maximum brightness of 1000 nits, and supports a 144Hz refresh rate.
It is available in three colors: Blue Topaz, Twisted Black, and Neon Pink.
The rear camera is a triple-camera combination, including a 108-megapixel main camera, a 50-megapixel telephoto lens, and a 13-megapixel ultra-wide-angle lens. In addition, it also has a 50-megapixel front camera.
There is a volume button and a power button on the right side.
There is a custom/instant button on the left side. You can set shortcut functions by long pressing or short pressing. At the same time, the power button can also be set as an instant button. Users can set functions such as turning on the camera, turning on the flashlight, playing music, etc. according to their needs.
There is a SIM card slot, a USB-C port, and two speakers at the bottom.
The width is about 75.8 mm (2.98 inches).
The length is about 159.93 mm (6.3 inches).
The thickness is about 8.81 mm (0.35 inches).
That's how big it is in the hand.
The dual USB-C cable is purple and made of soft and bend-resistant material.
ChargerLAB POWER-Z KM003C shows it doesn't have an E-maker chip.
HMD also launched the HMD SKYLINE Rugged Case. The box is white, with a rendering of the phone case in the middle and the HMD logo printed on it.
The phone case is black, has IP68 dust and water resistance, has reinforced corners, and comes with a lanyard.
The built-in magnet on the back allows for wireless charging.
This is how the HMD Skyline looks like wearing this case.
There is a waterproof and dustproof rubber plug for the charging port at the bottom.
The weight of the HMD Skyline is about 211.0 g (7.44 oz).
The weight of the HMD Skyline wearing the HMD SKYLINE Rugged Case is about 289.9 g (10.23 oz).
Wireless Charging Test
Charge with the Apple 35W charger and the MagSafe (A2140), the input power is about 8.97V 1.99A 17.85W.
The MagSafe magnetic charger can firmly attach to the HMD Skyline.
Reverse Charging Test
Use it to charge Huawei wireless earphones wired, and the output power on the phone is about 5.14V 0.50A 2.59W.
HMD Skyline also supports reverse wireless charging.
Compatibility Test
Next, let's do the charging compatibility test.
Third-party Chargers
Charging with the Apple 140W charger, the power is about 23.8W, using the PD protocol.
Charging with the AOHi 140W charger, the power is about 27.82W, using the PD protocol.
Most chargers were able to trigger a 9V voltage, with only a few operating at 5V.
We have compiled the test results into a bar chart. There are no compatibility issues. Nearly three-quarters of third-party chargers can provide it with more than 24W of power, up to 29.26W, and the rest are 10-23W.
Power Banks
Most power banks triggered the 9V voltage level, with only one operating at 5V.
We have compiled the test results into a bar chart. There are no compatibility issues. Most power banks can provide a charging power of more than 15W, with a maximum charging power of 24.72W and a minimum charging power of 10.77W.
Full Charging Test
We use the UGREEN 160W charger with the original cable to fully charge it. And put them into a 25°C (77℉) thermotank throughout the test.
The voltage is around 9.5V at first. The charging curve can be divided into three parts. In the first part, the power was around 31W for the first 22 minutes. Then, the voltage dropped to 9V. After that, the power dropped to 12W at 46 to 48 minutes. Finally, the power slowly drops to almost zero. It takes 1 hour and 27 minutes to be fully charged.
From this chart, it can be charged to 50% in 21 minutes and 80% in 39 minutes. It reaches 100% in 1 hour and 27 minutes.
Temperature Test
We also recorded the highest temperature on the front and back after charging for 10 minutes, 20 minutes, and 30 minutes.
10 minutes Charging
After 10 minutes, the maximum temperature on the front is 33.1℃ (91.58 ℉).
The back is 34.1℃ (93.38 ℉). It can be seen that the heat is mainly concentrated in the area below the camera.
20 minutes Charging
After 20 minutes, the maximum temperature on the front is 38℃ (100.4 ℉).
The back is 37.3℃ (99.14 ℉).
30 minutes Charging
After 30 minutes, the maximum temperature on the front is 38℃ (100.4 ℉).
The back is 37.4℃ (99.32 ℉).
We also turn it into another curve. The temperature during charging is between 33.1-38℃. The temperature on the front is always about 1°C higher than that on the back. The highest temperatures at 20 minutes and 30 minutes are basically the same. Combined with the charging curve, the charging power in this range is about 24-31W. The temperature is controlled within 38°C during charging, which is very good.
Summary of ChargerLAB
HMD Skyline adopts a right-angle body frame, and the front design pays tribute to the Nokia N9. It is equipped with a 4600 mAh battery and supports 33W wired charging, 15W Qi2 wireless charging, and 5W reverse wireless charging. It can be charged with an Apple MagSafe charger, and the power can reach 17.85W. In addition, the low power consumption of Qualcomm Snapdragon 7s Gen2 processor and large-capacity battery can meet the normal use needs of users for a day.
It can be charged to 50% in 21 minutes and 80% in 39 minutes. It reaches 100% in 1 hour and 27 minutes. During the charging process, the temperature is controlled within 38°C and the performance is good. It supports 33W charging (compatible with QC4.0 and PD3.0 PPS). When charged with third-party chargers, nearly 3/4 of the chargers have a power of over 24W, up to 29.26W, and the remaining chargers have a charging power of 10-23W.
Overall, the HMD Skyline is a model that has a certain sentimental appeal to old Nokia users. At the same time, the phone's appearance design, configuration, and charging compatibility all have certain advantages.
