Redmi K70 Pro experience: starting at 3,499 yuan, performance is still strong, appearance, photography and charging have been greatly upgraded

On November 29, the Redmi K70 series was officially released. There are three models in the series, namely:

  • K70E: starting price is 1,999 yuan, with three storage versions
  • K70: Starting price is 2,499 yuan, with four storage versions
  • K70 Pro: starting price is 3,499 yuan, with four storage versions

The large skylight design inherited from the flagship

When it comes to the design of the K series, I felt pretty good about the K60 before.

The back cover has a curved surface that fits the shape of the hand, and carbon fiber-like squares are added to the edges of the fuselage. Coupled with the rounded fuselage lines and the central punch-hole screen on the front, it is very comfortable to hold.

It's just that it lacks some unique features. If you throw it into the vast sea of ​​machines, it's still not easy to find it.

Now with the K70 series, Redmi has changed the conventional shape used by domestic Android phones. All three K70 models have adopted a tough right-angled frame design, and the DECO part on the back has become a large sunroof with a "panoramic window" that occupies the entire top of the back cover. Design, the three cameras and flash are neatly arranged into a four-frame structure.

Compared with the previous small design that was compressed to the upper side of the rear cover, the large sunroof DECO of the K70 series looks much more majestic.

If you put it together with Xiaomi MIX FOLD 3, you will find that the new design of the K70 series is more like a devolution from the MIX series, and the design can be regarded as the inheritance of a flagship symbol.

In addition to the DECO design and body shape, the K70 Pro also adds some new details to the back cover.

Redmi used velvet glass in the Qingxue and Moyu colors of the K70 Pro this time, and made subtle textures on it. The texture and black iron-like ink feather fuselage can present a basalt-like effect, making the fuselage look tougher.

The Qingxue color scheme also has the same texture. Redmi wanted to use the texture to depict a shape similar to the snow-capped mountains to cater to the theme of "Qingxue".

The K70E is positioned as the most entry-level model. It has the same "Qingxue" color body. The back of the K70E uses high-gloss glass, which lacks the texture of the velvet glass of the K70. It focuses on high-gloss, clean and smooth, and the bare machine feels moister than velvet glass. .

Both the K70 and K70 Pro use a 6.67-inch 3200 x 1400 2K 120Hz screen. The screen eliminates the plastic bracket and uses an ultra-narrow four-sided design without caulking glue. The effect of the narrow frame is more obvious. The square design with right-angled bezels makes it feel like you are holding a screen in your hand.

The screen material is a customized CSOT C8 material. The luminous efficiency is 15.9% higher than the C6 material used in the K60 Pro. The brightness in manual mode can be adjusted to a maximum of 700nits. The maximum excitation brightness of the full screen is increased to 1200nits. The highest peak brightness can reach 4000nits.

PWM dimming has been upgraded from 1920Hz of the previous generation to 3840Hz. The proportion of harmful blue light has dropped by 7% compared with the previous generation. Low blue light and stroboscopic damage to the eyes.

The screen supports 16,000-level automatic brightness adjustment, which can adjust brightness and color temperature according to environmental changes to improve viewing comfort.

In the face of screen updates, K70 Pro supports 8x HDR display and cinema mode, and supports picture adaptive function. Improving the look and feel of HDR videos when using video platforms such as Bilibili and Aiyouteng will also optimize the effect of audio playback, highlighting human voices and enhancing the sense of space.

Although it uses a 6.67-inch screen like the previous generation, the body size of the K70 Pro is a few millimeters narrower than the K60 Pro. However, due to the lack of the smooth transition at the bottom of the K60 Pro, the K70 Pro appears wider when held in the hand, which requires some readjustment.

While the body shape is updated, the protective case provided by the K70 series has been replaced by a gray matte protective case from the previous clear water case. The gray color can avoid the problem of yellowing after long-term use. The matte surface with anti-slip treatment is also comfortable to use. Overall, it is much better than the clear water case.

Signature flagship performance

Performance is the strong point of the K series Pro models, and the K70 Pro does it well as in previous years.

It is equipped with the latest Qualcomm Snapdragon 8 Gen 3 mobile platform, with up to 24GB of LPDDR5X memory and up to 1TB of UFS 4.0 flash memory. The heat dissipation part uses a 5000mm² annular cold pump ice cooling system, and the configuration has reached the flagship level in the second half of 2023. First echelon level.

The same goes for the running scores. When running AnTuTu on the K70 Pro at room temperature, the K70 Pro can exceed 2.1 million points, which is better than some flagship phones using Qualcomm Snapdragon 8 Gen 3.

After the performance improvement, K70 Pro supports the violent engine 3.0 technology assisted by AI technology, which can achieve lower power consumption, frame stabilization and image quality improvement through the HyperOS AI subsystem. The biggest upgrade in this regard is that the K70 Pro supports the 2K mode of "Genshin Impact".

Under normal conditions, the K70 Pro can set the resolution to 2K in "Genshin Impact" after upgrading. The resolution picture is much clearer. The edges of small icons, character outlines and textures on clothes have become clearer. The texture and shadow effects of rocks on large pictures have also become more delicate.

Unfortunately, after the resolution is increased to 2K, the bare metal K70 Pro can only run "Genshin Impact" at 2K 30fps. To increase the resolution to 2K 60fps, the phone must be connected to the Xiaomi Ice Cooling Backclip released at the same time. The heat dissipation power of this cooling back clip can reach 30W. After it is powered on and paired with the Bluetooth of the mobile phone, the 2K 60fps mode can be turned on.

If you don’t have high requirements for picture resolution and want to pursue smoothness, K70 Pro provides FRC and frame interpolation functions, supporting the 45fps upgrade to 90fps for “Genshin Impact” and the 60fps upgrade for “Peace Elite” and “Honor of Kings”. 120fps.

The image quality has been upgraded, and the high-pixel telephoto is back

In terms of cameras, the K70 Pro uses a standard three-camera structure of "ultra wide angle + wide-angle main camera + telephoto", which fills in the regret that the K60 Pro does not have a telephoto lens and makes the entire multi-camera system more complete.

The main camera uses the Light Hunter 800, a 1/1.5-inch 50-megapixel sensor that focuses on large dynamic range. The sensor supports dual native ISO Fusion Max technology, achieving a dynamic range of up to 13.2EV, which is six times that of the K60 Pro's main camera.

The K70 Pro's telephoto uses a 2X lens that is equivalent to close to 50mm.

Although more and more mobile phones are now adapting to portrait shooting, telephoto lenses will use a 3X lens with an equivalent viewing angle close to 75-80mm, and then provide a 2X lens through the digital zoom of the main camera.

However, if we consider practicality, the versatility of 2X will be higher than that of 3X, which has a narrower viewing angle. Users do not have such high distance requirements when shooting small objects around them. In addition, the K70 Pro telephoto also uses a 50-megapixel sensor, which can also achieve 2X to 3X zoom. As someone who frequently uses 50mm lenses all year round, I would prefer a setting like the K70 Pro.

The telephoto lens uses the Light Hunter 400 sensor, which is also part of the Light Hunter series, and has the characteristics of high pixels and high dynamic range. It is not difficult to see from the sample photos that the K70 Pro's main camera and telephoto can capture more light and dark details in HDR automatic mode.

In an environment with plenty of sunlight, the K70 Pro picture is overall bright, and the highlight positions are suppressed after processing, showing more details. The shadow part and the overall black level of the photo have been brightened, so the entire photo will basically not have an obvious situation where the highlights are all white and the shadows are all black.

▲ 100% zoom

The 50-megapixel Light Hunter 800 has good resolution. The output resolution in regular mode is pretty good. After the photo is enlarged to 100%, you can still see the texture of the walls inside and outside the window and the contents inside the coffee shop window.

When shooting with a 2X telephoto lens, the overall imaging style has not changed, it is a mode that demonstrates its own high dynamic performance.

▲ 100% zoom

The detail performance is also excellent, and you can also clearly see the hair on the puppy's head after zooming in to 100%.

In addition, the telephoto lens also has a good close-up effect. The longer focal length and the large aperture at close range make it easier to eliminate photos with obvious blur.

The 12-megapixel ultra-wide angle also has good imaging performance. The effect of detail characterization and overall light and dark control of the picture is similar to that of the main camera and telephoto. It can retain good details in the shadows, but the overall contrast will be higher than that of the telephoto and telephoto cameras. The main camera is higher and the picture is more transparent.

Based on the adjustment and optimization of the two light and shadow hunters in the initial firmware, the K70 Pro shows great dynamics while the picture is slightly low-contrast and has grayish HDR traces. Adjust the exposure appropriately when shooting, and adjust it in the album editing function after shooting. Contrast, if the picture is more transparent, it will look better.

Especially in this kind of scene where the light and shadow of the picture need to be preserved to show the tone, it is more important to select the focus point and control the exposure. The current high dynamic performance of K70 Pro seems to give users more choices. As for what style of picture to capture when shooting, it is up to the user to decide.

In portrait mode, the performance of the K70 Pro is quite satisfactory. When the environment is not too complex, the effect produced by using a small aperture is pretty good and more natural. If you want to shoot, it's okay to use it for close-ups of portraits, but it's still a little difficult to identify the foreground. It's better to keep the scene as simple as possible with less complicated relationships.

The K70 Pro performs particularly well in night scenes. After the Light Hunter 800 combines four pixels into one, the single pixel area can reach a large pixel of 2μm. With the f/1.68 aperture, the amount of light entering is 25% higher than that of the K60 Pro.

The overall picture is bright and clean, and even if you zoom in to the sky, there is no obvious noise. Highlight processing is good. The camera has been optimized in the shooting interface. A large number of highlight overexposures can no longer be seen in the preview.

The user presses the shutter at this time, and the phone will process it again when it completes the shooting. At this time, when you open the photo album, you can see that the photo shows the processed state. The phone will further suppress the highlights and brighten the dark parts, and the picture will look more balanced. This one deals more with highlights, and the dark parts have already been brightened during shooting. The preview effect here is not obvious.

The shadow part still retains a lot of details, but after brightening at night, it will have a slightly similar film fade effect. The overall contrast is not high. It is a little gray but not as obvious as during the day. Simply edit the photo. At the same time, I also hope that Redmi can adjust the HDR processing power in subsequent firmware, weaken it slightly, and make the picture contrast higher, so that the overall picture will look more transparent.

There are also some minor upgrades to the camera. For example, the night mode uses the Night Owl algorithm, which uses multi-frame fusion to achieve a higher degree of noise reduction and color calibration. After turning it on, the most intuitive change for shooting night samples is that the highlight suppression is better. Obviously, and the picture is cleaner.

The continuous shooting speed of the mobile phone has also been increased to 30 frames per second, making it easier to capture some decisive moments.

The rear camera of the K70E becomes a three-camera combination of "ultra wide + main camera + macro". The main camera uses a 64-megapixel OV64B sensor.

The shooting contrast in daytime environment will be higher than that of K70 Pro, and the overall image will be more vivid and rich, while the retention of dark details and the depiction of picture details are weaker than that of K70 Pro.

The imaging effect of the night environment is the same as that of the day. The picture can be kept clean. There is basically no obvious noise in the sky and dark light parts. When you zoom in, you will see some roughness on the wall. The highlight control is pretty good, but low-light positions will be a bit darker and not many details can be retained. It is recommended to use night mode as much as possible when shooting at night.

Return to over 100 fast charging

The K70 Pro is equipped with a large 5000mAh battery and a built-in battery management chip G1. The overall battery life is pretty good.

On the day we first got it for testing, we first charged it to 100% with a charger, then ran it three times in performance mode throughout the day, and then took sample photos from afternoon to evening. During this period, I plugged in a single card and turned on the performance mode of 5G data and battery management at full time. I browsed Weibo and web pages piecemeal on the way, and finally when I got home at about 8 o'clock in the evening, more than 45% of the battery was left. In terms of battery life, it is easy to cope with daily use with this battery life.

Charging has been greatly improved. The K70 Pro's fast charging has been increased from the K60 Pro's 65W to 120W, and it only takes 19 minutes to charge from 0-100%. This means that charging starts in the morning while washing, and you can go out with a full charge after breakfast.

As for the entry-level K70E, it is equipped with a 5500 mAh battery and supports 90W fast charging. Although the battery is larger and there is no fast charging support, the charging speed will be slower than the flagship K70 Pro, but it is sufficient for daily use.

Although the charging efficiency has been upgraded, the K70 Pro has also canceled wireless charging, and you have to go back to that line for charging at night.

In addition, the K70 series still uses a USB-A to C charging combination. If you go out for daily use, you still need to bring both the charging cable and the charger together. If you have other charging devices on you, it will be a bit troublesome to organize them.

Fortunately, this charging combination also supports PD, a universal charging protocol, so there is no problem in using it to charge laptops. If there is no requirement for the length of the charging cable, you can just use it.

A more comprehensive performance flagship

For the Redmi K series, the K70 series is a regular upgrade that brings the entire series closer to high-end flagships.

In terms of appearance, the K70 series does not need to settle for conventional designs. With the decentralization of Xiaomi MIX series design, coupled with Redmi's carving of velvet glass details, the K70 and K70 Pro already have their own characteristics in appearance, and their recognition is much higher than before.

Performance is still its strong point. With the help of Qualcomm Snapdragon 8 Gen 3, LPDDR5X + UFS 4.0 storage combination and other hardware, the K70 Pro has firmly established itself as the "performance flagship" in the Redmi and even Xiaomi product systems. For users who pursue body performance and gaming performance, this is the signature and trump card of the K70 Pro.

Charging makes up for the lack of 100-watt fast charging in the K60 Pro series. The camera has also been greatly improved in hardware after the addition of a high-pixel 2X telephoto lens and a light and shadow hunter series sensor, and photography has also made great progress. If the imaging style and details can be optimized and adjusted through firmware updates in the future, the K70 Pro shooting experience will be more complete.

Therefore, at this time when redmi is approaching its tenth anniversary, the K70 series has become more comprehensive while becoming stronger in performance.

When I recommended it before, I might have told you that you might have to make accommodations in other places for its performance. Now, these generals can be reduced.

Finally, let’s look at pricing:

  • K70 Pro: 12+256GB: 3299 yuan | 16+256GB: 3599 yuan | 16+512GB: 3899 yuan | 24+1TB: 4399 yuan
  • K70: 12+256GB: 2499 yuan | 16+256GB: 2699 yuan | 16+512GB: 2999 yuan | 16+1TB: 3399 yuan
