OPPO K9 Pro mobile phone review: hot appearance and cool core, a great value "light flagship" choice

Today's mobile phone market has fallen into a two-tier differentiation state: high-end products priced above 5,000 yuan are stacked with crazy features, and are rushing along the road of photography benchmarking cameras, chip frequency targeting computers, and running scores overwhelm game consoles; while products below 2,000 yuan are another scene, most of which attract more users by reducing various specifications to achieve the purpose of cost-effectiveness.

This situation has caused embarrassment for a group of people: they are not heavy game users, and they don't have the habit of taking a photo every two steps. For them, a "light flagship" that can meet most of their daily needs is the most ideal mobile phone: from the perspective of holding, the mobile phone should not be too thick; in terms of taking pictures, they don't need to be very professional, but they just want to get good results with just a casual shot; in daily use, it can also ensure smooth operation and good battery life, and meet mainstream game needs other than absolute running points.

At first glance, these requirements do not seem difficult to achieve, but if you think about it carefully, it is actually not easy to find products that can meet these "ordinary" requirements at the same time - many gaming phones on the market either do not perform well in heat dissipation or are too thick and heavy; camera phones are highly targeted, and for many users, hundreds of millions of pixels can be considered an overflow and a waste; and low-priced phones may not perform well in terms of durability, and after being replaced once a year, they do not seem to have a very high cost-effectiveness.

It can be said that there is still a big gap in the current mobile phone market in the field of "light flagship" that meets the mainstream market. OPPO has arrived in time, and the latest OPPO K9 Pro is targeting this market.

A "handy weapon" that is both good-looking and feels good to hold

Sun Wukong once turned the Dragon Palace in the East China Sea upside down for a "suitable weapon". For mobile phone users, a suitable mobile phone is not easily obtained either.

If the phone is too heavy and too wide, it is not suitable to hold or put in the pocket; if the back cover is too rough, it is uncomfortable to hold; if it is too smooth, it is easy to slip out of the hand. In addition, some common needs of today's users should be considered: the screen cannot be too small, the screen quality should be good, and there should be no battery anxiety.

So, when we turn our attention to OPPO K9 Pro, we find that its body adopts the same matte and matte process. The matte process of the back cover of the phone and the Picsas process on the camera module transition naturally and smoothly without any sense of disobedience. The feel of this material is a bit like the crystal diamond process of the OPPO Reno6 series, with bright colors, delicate feel, and not easy to get fingerprints.

The OPPO K9 Pro weighs 180 grams and is only 8.5mm thick, which is definitely thin and light for a phone with a 6.43-inch screen.

This size ensures that it is comfortable to hold in one hand, and it will not be cumbersome when placed in a trouser pocket. If you are tired of the "oppression" of your hands and trouser pockets by mobile phones weighing more than 200 grams, then OPPO K9 Pro can definitely give you a good reason to change your phone.

For a mobile phone, the feeling of holding it in your hand is the first impression.

But in addition to this, the touch of the phone's controls and the look of the screen are also very important. These factors combined together constitute the first impression the screen gives us.

OPPO K9 Pro uses a 6.43-inch Super AMOLED screen with a PPI of 409 and a screen-to-body ratio of 91.7%. It supports DCI-P3 wide color gamut and HDR10, making the entire screen look outstanding, and you can get the ultimate picture enjoyment whether it is movies or games.

In terms of control, OPPO K9 Pro supports the current top 120Hz refresh rate, and the operation is as smooth as silk, especially in information flow software, which can be described as "once used, it is hard to go back." In games, the 120Hz refresh rate can also bring a significant improvement in experience.

In addition to the screen quality, another major factor that constitutes the initial experience of the phone is battery life and charging. OPPO K9 Pro is equipped with a large 4500mAh battery and also supports 60W super flash charging technology.

According to actual testing, the phone still has 70% battery left after running "Genshin Impact" for 30 minutes, "Honor of Kings" for 40 minutes, Weibo for 30 minutes, and Bilibili video playback for 25 minutes.

Flash charging has always been the strength of OPPO phones, and OPPO K9 Pro is no lag behind in this regard. After testing, it can charge 30% in 10 minutes and 50% in 16 minutes. Fast charging plus excellent battery life make this phone completely bid farewell to battery anxiety.

At first glance, the OPPO K9 Pro has a high appearance, good hand feel, comfortable control, and excellent battery life. These factors combined are enough to leave a good impression on people. In terms of the most basic point of "handy", the OPPO K9 Pro can be said to have successfully scored high marks.

Balanced performance, ultimate heat dissipation

As a lightweight flagship, OPPO K9 Pro is equipped with the Dimensity 1200 chip from MediaTek (MTK). This top-level SoC from MTK supports UFS 3.1, giving it extremely fast reading and writing speeds. Its AnTuTu score is nearly 700,000 points, which is outstanding among mobile phones of the same price.

Although the OPPO K9 Pro is not positioned entirely as a gaming phone, it is also equipped with features such as 120-frame mode designed for the ultimate gaming experience. More importantly, its performance output is more stable.

OPPO K9 Pro has built-in HyperBoost performance scheduling and "stepless frame stabilization" technology, which enables it to predict game load in multiple dimensions during operation, reasonably schedule mobile phone performance, and make the game picture more stable.

In actual tests, "Honor of Kings" can run stably at 60 frames on the K9 Pro, and even a "big devil" like "Genshin Impact" can basically achieve no frame drops during operation.

OPPO K9 Pro also has a built-in game assistant that can instantly activate practical or interesting functions such as 4D vibration and game voice changing.

There is another secret that allows OPPO K9 Pro to run "monster"-level games stably, and that is heat dissipation.

Nowadays, mobile games have become more and more sophisticated, which puts higher demands on the performance of mobile phones. However, the space of mobile phones is not large, and in order to control the weight and volume, many manufacturers have sacrificed the heat dissipation performance.

OPPO K9 Pro does not compromise in this regard.

It uses a diamond solid-liquid dual-state cooling system, which is a cooling material first used in the aerospace field. Some high-end computer DIY players have just started using it, and now OPPO has applied it to mobile phones. This material has a higher thermal conductivity and can reduce the CPU temperature by up to 17 degrees.

In the actual test, after running "Genshin Impact" for half an hour, the temperature of the left and right grip areas on both sides of the phone was measured with a temperature measuring gun. It can be seen that the temperature of the right hand is controlled within the body temperature level, and the temperature of the left hand is slightly higher, but also within the acceptable range. It should be noted that "Genshin Impact" is already the most stressful mobile phone load among the common mobile games nowadays. It can be seen that the heat dissipation level of OPPO K9 Pro is enough to cope with any mainstream game nowadays.

For the target audience of lightweight flagship products, stability during operation is more important than the release of extreme performance, and OPPO K9 Pro's insight and control of this demand is thorough and precise.

Record the beauty of life

Photography has always been the strong point of the OPPO mobile phone family, and the OPPO K9 Pro is no lag behind. This phone is equipped with a 16-megapixel front camera, a 64-megapixel main camera, an 8-megapixel ultra-wide-angle lens, and a 2-megapixel macro lens.

The front camera supports AI Beauty 2.0, AI Makeup and other functions, allowing selfie lovers to take photos in different styles.

The OPPO K9 Pro's rear camera has 64 megapixels, and the photos it takes are rich and bright in color. Take the sky as an example, the effect is very realistic and moving, which is very suitable for taking landscape photos.

After turning on the 64-megapixel mode, the details of the photos will be richer and the imaging effect will be better.

The distortion of the ultra-wide-angle lens is also well controlled, and the stretching effect brings a stronger visual impact to the picture.

Switching the camera to night scene mode, you can see that the camera has sufficient light intake, and the darker areas of the picture can be clearly distinguished. The brightness is also relatively balanced, and there is no obvious halo around the text on the electronic display board.

In terms of video shooting, OPPO K9 Pro has added a front and rear multi-scene recording function, and the two cameras can work at the same time to help users create more interesting videos.

While using OPPO K9 Pro to take photos, the most appropriate adjective that comes to my mind is still "convenient". As someone who wants to take a photo from time to time, but doesn't want to spend too much time composing the photo, and even less willing to do post-editing, what I need is a phone that can easily take photos and automatically beautify them appropriately. The OPPO K9 Pro has an extremely fast imaging speed when taking photos, which is basically the same as the iPhone, and the resulting effect will not be too overwhelming. It is a product that is very suitable for recording life at hand.

A handy "light flagship"

It can be seen that OPPO K9 Pro did not blindly pursue the so-called "leapfrog" to compete head-on with higher-priced mobile phones, but used the best configuration in the same price range to do what it should do. For many users who do not have specific needs, allocating the overflow costs of some links evenly to the overall mobile phone is the truly value-for-money "light flagship" choice.

The biggest feeling OPPO K9 Pro gives people is "convenient": it is light and textured, and it is easy to hold; the screen is of high quality, supports 120Hz refresh rate, and is easy to operate; the chip adopts flagship configuration, coupled with performance scheduling and excellent heat dissipation, it is easy to use; the camera has fast imaging, the photos are of high quality, and it is easy to take.

There is no doubt that these features are enough to make OPPO K9 Pro a highly versatile mobile phone product. If you do not have a clear demand for a certain application field, and simply want to find a reasonably priced and comfortable mobile phone, then the OPPO K9 Pro "light flagship" is definitely an option worthy of your serious consideration.
