On April 24, OPPO K12 series was officially released. The K series has always been known for its balanced configuration and high cost performance, and OPPO K12 is no exception. It has 100W super flash charging with 5500mAh practical long battery life, is resistant to drops and folds, has good looks, and is also good at AI, imaging, screen eye protection, etc. There are many bright spots in this regard. I need to use two words to describe it, which is “solid”.
Next, let’s get started and actually test the OPPO K12 phone to see if it can achieve mid-range popularization of flagship experience.

Battery life: 5500mAh large battery + 100W fast charge
In terms of configuration, OPPO K12 is equipped with a long-life version of 100W super flash charge + 5500mAh large-capacity battery. The battery uses a high-voltage resistant lithium cobalt oxide system battery to achieve high energy density. It can provide higher energy density under the same volume, and has a thin and light body. It can accommodate a larger amount of power; the 100W super flash charge also adopts a new DC architecture, which increases the speed of blood replenishment and eliminates charging anxiety.
In this actual measurement, the brightness of the mobile phone was set to 200 nits at room temperature. During the entire test, the mobile phone was placed on an unobstructed mobile phone base at the front and rear. The mobile phone was set to the standard version mode. The color mode and dimming mode of the mobile phone screen were both factory default settings. The network environment is Wi-Fi and no SIM card is inserted.

After connecting to the original charging set, the fast charging results of OPPO K12 are as follows:
It can be seen that OPPO K12 can charge about 20% of the 5500mAh large battery in just 5 minutes. It takes more than half of 15 minutes and is fully charged in about 30 minutes. This speed is almost the same as that of high-end flagships. Mid-range products can also popularize flagships. level of charging speed.
Many users have the need to charge before going to bed at night, but if the mobile phone battery remains empty or fully charged for a long time, it will also have an impact on the lifespan. This OPPO K12 supports long-term charging at night. The system will stop charging when it detects that the battery reaches 80%, and it will be fully charged until early in the morning at a specific time, allowing you to go out with a full charge every morning.
After the battery was fully charged, we also conducted a five-hour intensive battery life test on OPPO K12. The same test environment included the following items:
Play the game in full screen for 30 minutes;
Watch 90 minutes of iQiyi movies;
Enter Douyin and watch videos for 60 minutes;
Enter the Taobao homepage and slide for 30 minutes;
Brush up on Toutiao news for 30 minutes;
Record 1080P 30 frames video for 15 minutes; the default main camera takes 15 minutes for a total of 30 minutes;
QQ Music plays on the screen for 30 minutes.
OPPO K12 still has nearly 70% of its power remaining after the test. It can be charged once a day during normal use.In order to further extend the service life of the mobile phone, this machine also uses an exclusive intelligent battery health algorithm and bionic repair electrolyte technology.The battery capacity can still be maintained at greater than or equal to 80% after 1,600 playback cycles. Heavy mobile phone users are not afraid of rapid battery health decline.
Design: resistant to falling on all sides, yet elegant design
In terms of appearance design, OPPO K12 focuses on a simple style. The design of the right-angled middle frame + curved back cover makes it feel tough in the hand, but thanks to the excellent corner processing, it does not pinch the hand. The rear camera module is a classic 1-shaped dew Deco, without too much protrusion, and the lens will not touch the palm of the hand when held horizontally.
OPPO K12 provides two colors this time. The one we got is the “Starry Night” color, which uses gold-labeled glitter sand technology. The gloss on the back is more textured and more restrained. Users who like bright colors can choose the “Qingyun” color, which uses Nano-brightening optical film technology makes the texture more layered.
While it looks good, OPPO K12 also has special optimizations in terms of durability. It adopts OPPO's exclusive self-developed “super anti-fall diamond structure design”. The six sides of the phone, the front, rear, left, right and four corners are equipped with anti-fall protection. The four corners are elevated and reinforced, allowing the phone to “land softly” when dropped at any angle. .
The interior of this machine is made of magnesium-aluminum metal skeleton. There are supports and protections between the upper and lower covers of the motherboard, cameras, chips and other parts. Hardware such as speakers, earpieces, flash covers, motors and other hardware also have buffer foam for sticking and fixing. The buffering effect is like a multi-directional “airbag” placed in a mobile phone.
With its hard-core drop-resistant configuration, OPPO K12 has passed more than 50 rigorous machine quality tests including three-proof, safety, climate, chemical, and mechanical categories, creating flagship standards and championship quality, and has been recognized by authoritative organizations.It has won the “Swiss SGS Gold Label Five-Star Complete Machine Fall Resistance Certification”, making it safe to use.
Turning to the front of the phone, OPPO K12 uses a 6.7-inch LTPS flexible straight screen to reduce accidental touches in games. It supports 120Hz screen refresh rate, HDR10+ certification and frame sharing ultra-high definition certification, ensuring an excellent visual look and feel.
OPPO mobile phones have always attached great importance to eye protection configuration. This OPPO K12 supports 1Pulse DC dimming under medium and high brightness conditions. It also supports 2160Hz PWM high-frequency dimming when the screen brightness is low, reducing eye discomfort caused by stroboscopic. Taking care of users’ eye health, OPPO K12’s excellent eye protection capabilities have also allowed OPPO K12 to obtain TV Rheinland hardware-level low blue light certification.
Performance: smooth operation, low power consumption, long-lasting use
In terms of performance, OPPO K12 is equipped with Qualcomm’s third-generation Snapdragon 7 mobile processing platform. It has a high-performance core cluster, including large cores, medium cores and small cores, which can achieve a good balance between multi-tasking and energy saving.
In terms of memory, it is equipped with three versions: 8GB+256GB, 12GB+256GB, and 12GB+512GB to meet the storage needs of different users. Users with larger memory needs can also enable up to an additional 12GB expansion. It also supports 1TB card storage expansion, high-definition drama You can save as much as you want.
The first is the running score test. OPPO K12 scored 926,652 points in the AnTuTu V10 test, which is in line with the positioning of this phone.
With low power consumption and good performance, OPPO K12 is enough to meet the daily needs of most users. Some large games can also bring stable and smooth frame rate performance after simple settings. This time we chose the popular “Golden Shovel War” for testing. The actual results are as follows:
OPPO K12 “Golden Shovel War” test
The picture in “The Battle of the Golden Shovel” is set to 60 frames + high quality, and the game process is still very smooth. If you want to check the lineup while playing, you can also draw the OPPO Game Assistant on the side and check the powerful lineup at any time, which is very convenient.
After the game test, it was found that the OPPO K12 body basically did not generate heat. It uses a new high-performance graphite heat dissipation material. The total graphite area reaches 11147mm, which has stronger thermal conductivity. It has a 4129mm? super large flagship-level VC liquid cooling radiator and 11 temperature sensors. Regardless of gaming or daily use, downloading large files, updating large games, or shooting videos for a long time, there will be no obvious heating.
In order to ensure continuous gaming even in weak network environments, OPPO K12 adopts a design with 8 high-performance antennas surrounding the body. The multi-position layout can effectively enhance the experience. Not only that, a game-specific antenna is also designed separately on the side of the fuselage, which can maintain a good signal connection when the user holds the phone with both hands to play games, allowing smooth gaming and continuous network connection.
Image: 50-megapixel main camera with flagship algorithm, excellent in multiple scenes
The OPPO K series is also known for its good image quality, and this time the OPPO K12 is no exception. It is equipped with a 50-megapixel ultra-clear main camera, using a Sony IMX882 sensor and supporting OIS optical image stabilization. This lens alone is It is enough to handle daily photography scenes, and there is also a 112° ultra-wide-angle lens to meet more creative shooting needs.
In bright scenes, the high-standard main camera of OPPO K12 can accurately record what the human eye sees. The exposure is good, and the details are clear after partial enlargement. The colors are true and natural, and the backlight part of the building is also relatively clear, without being blurred. Too much smear.
In order to provide a better visual experience when displaying high dynamic range image (HDR) photos, OPPO K12 also supports “Super Light and Shadow Pro XDR Display”. Press the button to expand the dynamic range of the display through the screen brightness and restore the natural scene. Every inch of light and shadow.
Since the main camera supports OIS, OPPO K12’s shooting effect in dark light environments is also guaranteed. OPPO’s flagship imaging algorithm can map and adjust the overall color in the picture through multi-frame digital film fusion calculation, RAW domain processing and segmentation algorithm. , making the details more complete.
The shooting effect of OPPO K12 in dark light environment is acceptable, the dark area is relatively pure, and it provides a good trade-off between details and noise. The shooting effect of this flagship main camera is really a bit of a dimensionality reduction at this price.
OPPO's highly acclaimed AI elimination function is not absent this time. If irrelevant passersby appear in the photo, we no longer have to spend extra energy to manually retouch the photo. We only need to circle the person in the editing function, and AI will recognize the photo. content, and intelligently eliminate and fill in the background.
