On April 24, the OPPO K12 series was officially released. K series has always been known for balanced configuration、High cost performance,And OPPO K12 is no exception,100W super flash charge with5500mAhPractical large battery life、Drop resistance and fold resistance,The appearance is not bad,It also has a lot of highlights in AI、Image、Screen eye protection, etc.,To describe it in two words,It is"solid"。

Next, let's get our hands on the OPPO K12 and see if it can achieve the mid-range popularity of the flagship experience.

Battery life: 5500mAh large battery + 100 watt fast charging

In order to reduce the budget, the large battery and fast charging of the common mid-range mobile phones on the market are always incompatible, and OPPO has been working the road of flash charging for a long time, and this OPPO K12 will also take battery life as a major selling point, let's test its strength first.

In terms of configuration, OPPO K12 is equipped with a longevity 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 in the same volume, and the thin and light body can also accommodate more power;

In this test, the brightness of the mobile phone was set to 200 nits in the room temperature environment, the mobile phone was placed on the front and rear unobstructed mobile phone base during the test, the mobile phone was set to the standard mode, the color mode and dimming mode of the mobile phone screen were set by factory default, the network environment was Wi-Fi, and no SIM card was inserted.

After connecting to the original charging kit, the fast charging results of the OPPO K12 are as follows:

It can be seen that OPPO K12 can charge a 5500mAh large battery with about 20% power in only 5 minutes, more than half of 15 minutes, and about 30 minutes to be fully charged, which is not much faster than that of high-end flagships, and mid-range products can also popularize flagship-level charging speeds.

Many users have the need to charge before going to bed at night, but if the mobile phone battery is kept empty and fully charged for a long time, it will also affect the lifespan. This OPPO K12 supports long-term charging at night, and the system will stop charging when it detects that the battery level reaches 80%, and it will be fully charged at a specific time in the early hours of the morning, so that you can go out with a full charge every morning.

After the battery was fully charged, we also tested the Oppo K12 for five hours of heavy battery life, and the same test environment included the following items:

Play the game in full screen for 30 minutes;

Watch iQIYI movies for 90 minutes;

Enter Douyin to brush the video for 60 minutes;

Enter the Taobao homepage and slide for 30 minutes;

Today's headlines brush the news for 30 minutes;

Record 1080P 30 fps video, 15 minutes of recording, default main camera takes 15 minutes, total 30 minutes;

QQ music plays on the screen for 30 minutes.

OPPO K12 can still have close to 7% of the battery left after the test, and it is no problem to charge it once a day for normal use. In order to further extend the service life of the mobile phone, this machine also adopts the exclusive intelligent battery health algorithm and bionic repair electrolyte technology, which can still maintain the battery capacity greater than or equal to 80% after 1600 replay cycles, and heavy mobile phone users are not afraid of rapid degradation of battery health.

Design: Ten sides are resistant to falls, and the design is elegant

In terms of exterior design, OPPO K12 focuses on a simple style, with a right-angled middle frame + curved back cover, which makes it feel tough in the hand, but thanks to excellent corner processing, it is not awkward. The rear camera module is a classic 1-line dew Deco, which does not have too many protrusions, and the lens will not touch the palm when held horizontally.

OPPO K12 provides two colors this time,What we got is"Starry Night"Color matching,Using gold label flash sand process,The gloss on the back is more textured,More restrained;Users who like bright colors can choose"Qingyun"Color matching,Using nano brightening optical film technology,The texture can show a more layered sense。

While the appearance is good, the OPPO K12 also has special optimizations in terms of durability. It adopts OPPO's exclusive self-developed "super anti-drop diamond architecture design", the front and back of the mobile phone on the left and right sides + four corners have anti-drop protection, and the four corners are raised and reinforced, so that the mobile phone can be "soft landing" when dropped at all angles.

The inside of the machine is made of magnesium and aluminum metal bones, which are supported and protected between the upper and lower covers of the motherboard, cameras, chips and other parts, and the hardware such as speakers, earpieces, flash covers, motors, etc., as well as buffer foam to play a role in pasting and fixing and buffering, just like a multi-directional "airbag" in the mobile phone.

With the hard-core drop-resistant configuration, OPPO K12 has passed more than 50 rigorous quality tests of the whole machine such as three-proof, security, climate, chemical, and mechanical, creating a flagship standard and champion quality, and has been recognized by authoritative institutions.

Flipping to the front of the phone, the Oppo K12 uses a 6.7-inch LTPS flexible vertical screen on the front to reduce false touches in games, and supports a 120Hz screen refresh rate, HDR10+ certification, and Frame Enjoy Ultra HD certification to ensure an excellent visual appearance.

OPPO mobile phone has always attached great importance to eye protection configuration,This OPPO K12 supports 1Pulse DC dimming in medium and high brightness conditions,When the screen is low brightness, it also supports2160HzPWM high-frequency dimming,Reduce eye discomfort caused by stroboscopy,Care for users' eye health,Excellent eye protection ability also makes OPPO K12 win the German Rheinland T? V hardware-level low blue light certification.

Performance: Smooth operation and low power consumption, always new for a long time

In terms of performance, the Oppo K12 is powered by Qualcomm's third-generation Snapdragon 7 mobile processing platform, which has a high-performance core cluster that includes large, medium, and small cores, which can strike a good balance between multitasking and energy saving. In terms of memory, it is equipped with 8GB+256GB, 12GB+256GB, 12GB+512GB three versions, to meet the storage needs of different users, users with larger memory needs can also turn on up to an additional 12GB expansion, and at the same time support 1TB card storage expansion, save as much as you want for high-definition dramas.

The first is the benchmark test, and the OPPO K12 received a score of 926652 in the Antutu V10 test, which is in line with the positioning of this phone.

With low power consumption and decent performance, the Oppo K12 is more than enough for most users to use on a daily basis, and some large games can also bring stable and smooth frame rate performance even after simple settings. This time, we chose the popular "Battle of the Golden Shovel" for testing, and the actual results are as follows:

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 when playing, you can also draw out the OPPO game assistant on the side, and check the strong lineup at any time, which is very convenient.

After the game test, the OPPO K12 body basically did not heat up, using a new high-performance graphite heat dissipation material, with a total graphite area of 11147mm?, and stronger thermal conductivity. Owning 4129mm? Extra-large flagship-sized VC liquid cooling heatsink and 11 temperature sensors. Whether it is a game or daily use, or when it comes to downloading large files, updating large games, or shooting videos for a long time, there will be no obvious heating phenomenon.

In order to ensure that the game can be played continuously even in a weak network environment, the OPPO K12 adopts a design with 8 high-performance antennas around the fuselage, and the multi-position layout can effectively improve the experience. Not only that, but there is also a separate game-specific antenna on the side of the fuselage, which can maintain a good signal connection when the user holds the mobile phone to play games with both hands, and the game is uninterrupted.
