Lenovo K12 Pro Review: Budget Smartphone with Snapdragon 662 and NFC

You know, I haven’t reviewed smartphones from the Lenovo brand for a long time. Somehow they didn’t often come across to me, but today I want to tell you about one interesting model called Lenovo K12 Pro.

I note right away that this device belongs to the segment of the mid-budget class and the price tag is quite tempting. For example, you can currently get the Lenovo K12 Pro model for just $ 170.


For this price, you get a very large 6.8-inch HD screen, Snapdragon 662 processor, 4GB, and 64GB memory versions. The smartphone is powered by the Android 10 operating system and has a good 6,000mAh battery with a 20W fast charging.

The new K12 Pro model is very similar to the popular smartphones from the Xiaomi brand. I have models like Poco M3 and Redmi 9T. Therefore, in this review, you will find out the main differences between these smartphone models and will be able to make the right choice.

Thus, I offer my complete and in-depth review from the inspection of the appearance of the packaging. And then look at the design, specifications, check the camera and battery endurance.

Unboxing and packaging

I ordered a Lenovo K12 Pro device in the Chinese market through a seller on Aliexpress and a smartphone came to my hands in about three weeks. The box itself has received standard dimensions and is made in a combination of white and blue.

On the front, you can see only the name of the company and the model. But since I do not have a global version, there are inscriptions with Chinese hieroglyphs on the packaging.

Inside the box, I found the smartphone itself, which was already packed in a protective silicone transparent case. This is good news since at first, you will need it in order not to scratch the body of the device.

Next, I found a set of instructions in Chinese and English, a needle for a SIM card, a Type-C charging cable, and a 20W power adapter. That’s all, I didn’t find anything else in the configuration. Ok, let’s move on and take a closer look at the appearance of the device.

Design, workmanship, and materials

I have already said that the Lenovo K12 Pro smartphone belongs to the mid-budget class of devices. Therefore, it makes no sense to expect premium materials in your performance. The device is made of matte corrugated plastic, which practically does not leave traces of fingerprints.

The manufacturer offers two colors to choose from – black and purple. The choice is not the widest, but as for its class of devices, the user will be able to make the necessary choice. But I think purple will work for women and black for the opposite sex.

I have no strong complaints about the quality of performance, everything was done well and without unnecessary problems. For example, the buttons got a good move and response, and while using the smartphone, I did not find extraneous squeaks and sounds. This is despite the fact that the device is made entirely of plastic, both the rear and side ends.

Don’t forget that the screen size on the front is a whopping 6.8 inches. Thus, the dimensions and weight of the device will not be so small. For example, in the case of the K12 Pro model, the dimensions were 172.1 x 76.8 x 9.7 mm and the weight was about 220 grams.

From this, we can conclude that the smartphone will not be comfortable to use and the device is not comfortable in the hand. But if you hold your smartphone with both hands while watching videos or playing games, then you will get a lot of emotions from the larger screen.

Let’s tell you a little about what the screen itself is. Lenovo K12 Pro has a large 6.8-inch IPS LCD screen with a resolution of 720 x 1640 pixels. You might think that this is a very small resolution for such a large screen. Yes, maybe I agree with you, as the pixel density per inch was 263 PPI.

But as my practice has shown, even with such a density, I did not see individual pixels. And if I had not been told that this screen has only HD resolutions, I would not have seen the difference between Full HD and HD resolution.

Apart from that, I liked this screen, namely how it displays colors and also the maximum value of the brightness level. But here’s a small disappointment was the rather large bezels around the screen, especially the lower chin.

If we compare the screens with their competitors Poco M3 and Redmi 9T, then their screens will be better. Let me remind you that both smartphones received the same screen size of 6.53 inches and have Full HD resolution. But what made me happy about the K12 Pro is the round cutout for the selfie camera in the upper right corner. But on models from the Xiaomi brand, the front camera was located in a waterdrop notch.

The back of the smartphone received three sensors of the main camera with LED flash. And in the central part, there is a round sensor for a fingerprint scanner. This may not be the most convenient location for the fingerprint scanner, but this scanner works very well and responds quickly to a finger. Let me remind you that the Poco and Redmi models received the location of the fingerprint scanner on the right side of the case.

Ok, now let’s talk about the button and the external interfaces of the K12 Pro model. The right side received a power button and a volume rocker. But on the opposite side, you can see a hybrid slot for dual nano-SIM cards or one nano-SIM card and memory card. Also, just below the slot, there is an additional button with a Google Assistant.

Meanwhile, there is an additional microphone on the top with a 3.5 mm audio jack for headphones. And at the bottom, there is one speaker, a Type-C port for charging, and a microphone base. As for the sound quality, it plays pretty well. In addition, various audio mode settings can be found in the user interface. Where you can tune and select the genre of music, increase the bass or decrease the mids. Ok, now let’s find out what the device is capable of in real life.

Performance, benchmarks, games, and OS

Lenovo has always cooperated with the Qualcomm brand and I have not seen processors from MediaTek in its models. In the case of the Lenovo K12 Pro model, everything is also the same, that is, a Snapdragon 662 processor has installed onboard the smartphone.

The exact same processor is used on the Poco M3 and Redmi 9T models. This is an 11-nanometer chipset that has eight cores with a maximum clock speed of 2.0 GHz. In the benchmark tests, everything is just as good. For example, the K12 Pro smartphone scored about 180 thousand points in the AnTuTu test.

In terms of gaming capabilities, the device uses the Adreno 610 graphics accelerator. It shows ideal results in demanding and heavy games. I was able to run my favorite games like Call Of Duty, PUBG Mobile, and others. Naturally, the graphics settings were average, but during games, I did not notice any lag. Even after one hour of continuous gaming, the smartphone was not hot.

I have a version of a smartphone with a modification of 4 GB of RAM and 64 GB of internal memory. Also, you can find 4 and 128 GB memory versions. The read and write speed of the internal memory did not disappoint me. The value was in the range of 320 MBps reading, and writing – 185 MBps. In addition, you can easily expand the memory using the microSD card slot.

I can also mention a good wireless connection. The Lenovo K12 Pro smartphone uses a dual-band Wi-Fi module, built-in GPS, and Bluetooth 5.0 version. But the most interesting feature is the presence of an NFC module for contactless payment of your payments. I did not notice any problems with the above modules and sensors, and during my tests, they all worked well.

As for the operating system, the smartphone received control from the stock Android 10. I am not exactly sure whether the device will have the new Android 11. Only time will tell, but I did not find any information about the update.

Out of the box, despite the fact that the device was intended for the Chinese market, Google services and applications were already preinstalled. Also onboard the device has many languages. At the same time, I did not find any problems with the work of the user interface. All functions, features worked quickly and without any freezes.

Camera and sample photos

There are triple camera sensors on the back of the Lenovo K12 Pro device. You might think that a smartphone has four camera modules in terms of looks. But in fact, the fourth module is an LED flash. The main sensor received a resolution of 64 megapixels and shows excellent results both in the daytime and at night.

Although I did not notice a strong difference between the main module on Poco M3 and Redmi 9T smartphones with 48 megapixels and the K12 Pro model. But this is if you do not enlarge the photos and check the details. Naturally, on the Lenovo smartphone, the detail was slightly better than that of its competitors.

The second and third sensors have a resolution of 2 megapixels with an aperture of f/2.4. They were created for macro and bokeh modes. Both modules work well, but the detail of the macro mode did not please me much.

The front of the device houses a selfie camera with a resolution of 16 megapixels. It shows a good result in terms of the quality of photos, but this is if you do not take into account poor lighting.

What I didn’t like about the K12 Pro is the lack of an ultra-high mode and a maximum video resolution of only 1080p. Although I was pleased with the fact that the frame rate in seconds for the main camera was 60 fps. You can also see below examples of various photos taken with the Lenovo K12 Pro.

Battery and charging speed

The last section I would like to share with you is about battery life. The Lenovo K12 Pro has a decent 6,000mAh battery with 20W fast charging.

In real life, this battery capacity even with active use lasts for a full two days. I have used the device in rather difficult conditions. For example, I ran various benchmark tests, played games, watched various videos on Youtube, and performed other daily tasks. Yes, you can even achieve a result in 3 days, but for this you need to use your smartphone as intended.

But the charging time of the battery took about 2 hours and 15 minutes of my time and I think this is a good result for the large capacity of the built-in battery.

Conclusion, reviews, pros, and cons

The new Lenovo K12 Pro smartphone turned out to be not the worst for a mid-budget device. In some points, the best side of it in comparison with competitors, and in others worse.

Let’s talk about the positives first. The first thing I liked about the K12 Pro is its large screen size, which doesn’t look as bad in quality as it seems from the specs. I also liked how the smartphone is assembled and how it behaves in terms of performance.

The device performed well in benchmark tests, in games, and even the user interface is fast and stable. In addition, the 64-megapixel main camera shows good results even in low light. And the battery life will only delight the future user.

The disadvantages I can attribute are the large dimensions and weight of the smartphone, as well as the lack of an ultra-wide camera module. I would also like to get a Full HD screen resolution, as I think HD resolution is rather weak.

Price and where to buy cheaper?

Currently, you can buy the new Lenovo K12 Pro smartphone at a decent price of $ 169.99 with a 47% discount.

When compared with competitors, the Poco M3 and Redmi 9T models have a slightly lower cost and better technical stuffing in some aspects. But the Lenovo brand has some trump cards up its sleeve – a 64 MP main camera and the presence of an NFC module.
