Huawei P40 Review: Things That You Need To Know


The Huawei P series has retained and extended the flagship with a large screen and small size for us. By the current generation, the Huawei P40, it adopted a full-screen design with a high screen-to-body ratio and plugged a large 6.1-inch screen with a body comparable in size to the iPhone 11. Recently, the author started to evaluate the P40 and P40 Pro of Huawei P40 series. In terms of feel alone, for the 6.58-inch Huawei P40 Pro, my feeling is that this size is just right in the hand. For the 6.1-inch Huawei P40, holding it in my hand makes me feel a small and exquisite reunion after a long time.

While maintaining a small size of 6.1 inches and 175g, the Huawei P40 also incorporates a 1 / 1.28-inch super outsole main camera with the same brother P40 Pro and P40 Pro +, overcoming the heavy test of the internal stack design. Next, let’s conduct a comprehensive and in-depth understanding through evaluation.

HuaweiP40 Design & Appearance

Huawei P40 is available in five colors: zero degrees white, deep ocean blue, bright black, morning gold, and frost silver. We have zero degrees white in our hands. As Huawei has always claimed, the design of the P40 follows an elegant and refined style. This back sometimes reminds people of pocket cameras of another era.

The 6.1-inch screen resolution of the Huawei P40 is 2340 × 1080 pixels, and it is made of OLED material, and the daily operation is smooth and smooth. Looking at the oval black area in the upper left corner of the screen, there is a 32MP selfie camera + infrared camera.

The opening of the earpiece is completely eliminated on the Huawei P40. The sound technology of the magnetic suspension screen is adopted. The phone screen is the earpiece. In this way, there is no opening on the screen, and there is no opening in the glass. Plug holes and noise after use.

At the top is a noise reduction microphone. The bottom has a speaker opening, microphone, USB-C port, and SIM card slot. In the black matrix gathered by the rear camera modules, you can find a 50MP main camera, a 16MP ultra wide-angle camera, an 8MP telephoto lens, and a dual-tone LED flash.

3. Video experience: How strong is the perception of the IMX700 card?

Both P40 and P40 Pro have Huawei ’s largest 1 / 1.28-inch ultra-large bottom sensor to date, RYYB filter array, full-pixel octa-core focusing, and are equipped with XD Fusion image engine, which supports AI HDR + high dynamic range,

The Huawei P40 has a 204,800 ISO sensitivity range and is equipped with a multi-spectral color temperature sensor. Rear-mounted super-sensing Leica triple camera, including 50-megapixel IMX700 super-sensing main camera (F1.9 / wide-angle), 16-megapixel super wide-angle lens (F2.2), an 8-megapixel telephoto lens (F2.4 / OIS (Shake), support 3x optical zoom, 5x hybrid zoom, 30x digital zoom.

I have used Huawei P40 Pro for a long time before, but now I am switching to Huawei P40. In terms of the experience of the imaging system, there is no alienation from the diaphragm, and the transition is smooth. Combining the experience of two mobile phones, what I feel most intuitively is that both the Huawei P40 and P40 Pro have changed significantly compared to the previous generation, and attention has shifted to the lower limit.

From the P20 series to the present, Huawei ’s flagship models have focused on raising the ceiling of the imaging system, such as clear restoration in extremely low light, telephoto lenses drag the framing content to the limit of the naked eye, and the well-known powerful HDR capability and stack Mode to challenge the limits of mobile photography.

However, the design of various lifting ceilings still has certain obstacles for ordinary users who do not know much photography knowledge and conventional skills. Take the author as an example. In the past, the grasp of the photography environment and the understanding of the parameters are not very comprehensive. Often, the camera is turned on for a shot, and rarely in the professional mode.

I believe this is also the usual operation of most people using mobile photography in daily life. What Huawei P40 does is to focus on everyone’s daily “hand shot”, click the camera, do not adjust the parameters, press the shutter, you can take the best picture with exquisite picture quality.

This time, the Huawei P40’s automatic HDR in backlit and high light ratio scenes has reached a new height, especially for the enhancement and restoration of details in dark parts.

HuaweiP40  Cameras

The customized IMX700 sensor of the Huawei P40 series is up to 1 / 1.28 inches, which is only one step away from 1 inch.

In the minds of many people, 1-inch CMOS is a watershed and reaches the 1-inch level, such as Nikon J series micro-single, Sony’s RX100 series black card, are 1 inch, all considered to be the size of mobile phones can hardly come close. The special presence of the Huawei P40 series, which upgrades the main camera size to nearly 1 inch, is already challenging the final dignity of card cameras today.

The significance given by the IMX700 super-sensing lens to the Huawei P40 is that if you do not pursue further fine-grained details or imaging in extremely low-light environments, it is not necessary to turn on the night scene mode, and its own light intake is sufficient to cope with ordinary cities. Night scenes can be easily captured.

Compared with Huawei models in the past, the dynamic range, picture quality, and tone of tone have great adjustment tendencies. It should be known that the past Huawei video flagships are used to high-contrast, high-saturation, high-sharpness movies, and good eyeballs, but now they are moving towards natural and delicate.

The wide-angle lens can provide a larger angle of view, allowing the photo to accommodate more scenery. In terms of overall picture quality, the picture quality of the ultra-wide-angle lens of the Huawei P40 is not worse than the main camera under sufficient light conditions, but Due to the limitation of pixels, the resolution is slightly weaker.

Huawei P40 achieves full focal length coverage beyond our daily high-frequency use scenes. It supports 3x optical zoom, 5x hybrid zoom, and 30x digital zoom. The 5x hybrid zoom here refers to the combination of the three cameras of the main camera, super wide-angle main camera, and telephoto lens to achieve excellent 5x zoom effects in various environments through different combinations.

3x shooting at night

It can be seen that whether it is a 3x optical zoom or a 5x hybrid zoom, Huawei P40 solves the problems of chromatic aberration and color loss that are common in most high-magnification models.

HuaweiP40 Hardware

Thanks to Huawei’s strong communication technology strength and the in-depth empowerment of the world’s first flagship 5G SoC Kirin 990 5G. The Huawei P40 series still has the best 5G performance in the industry.

Specifically, the Kirin 990 5G is based on the industry’s most advanced 7nm + EUV process. The 5G Modem is integrated into the SoC for the first time, with a smaller area and lower power consumption.

According to the “Blue Ocean Strategy” created by Qian Jin and Dr. Mobonje-the product is essentially a value design. Huawei P40, as the model with the lowest entry threshold for the P40 series. Naturally withstands relatively higher value design pressure, which often makes it not advantageous in the comparison game of the “digital size” of the paper parameter table obsessed by some users.

What is the comparison game of “digital size” on the paper parameter table?

Many times, many people talk about mobile phones spending most of their time counting. And the three digits are larger than the size-for example, 990 is larger than 980. And the slightly more difficult thing is that the 40 megapixels are smaller than the 50 Megapixel number. Even in the division stage, it is not easy for some users to digest. And understand the 1 / 1.7 pixel CMOS area and the 2/3 pixel CMOS area.

The Huawei P40 has many parameters that need to be experienced in addition to its parameters. Such as face value, craftsmanship, and even the lightness and thinness that many large-sized. And large-screen mobile phones have lost today. Why emphasize non-parametric content? Because this dimension is often overlooked by so-called “parametric party” users.

If a product needs to be judged only by a parameter table used to compare the “number size”. There is a big logical problem. Powerful parameters are just a means to complete a good product., Which is definitely not the ultimate goal. The purpose of the parameters is for experience, and experience builds on user needs.

Huawei P40 is a small-sized mobile phone, only 6.1 inches, and weighs only 175g. Moreover, Huawei P40 has also taken on the role of popularizing the IMX700 super-sensing lens, but in such a body size. The Huawei P40 incorporates the IMX700 1 / 1.28-inch super outsole lens. Which puts a high test on the stacking design.

The Huawei P40 not only crams this 1-inch special presence into a 6.1-inch thin and light body but also lowers its starting price to 4188 yuan, saying that it is an IMX700 popularizer.

It is worth mentioning that, as one of Huawei’s dual flagships in parallel with the long-term business fan’s Mate series. Huawei P series users have many women, pursuing small and light, good grip, online value. And strong design, It is best to have a powerful photography system that can take beautiful pictures.

The Huawei P40 accurately captures this kind of demand, and the 6.1-inch and 175g weight bring an excellent feel. The colors such as frost silver and morning gold, as well as the AG matte process and metallic luster on the back. Bring absolute superior value and exquisiteness. It can be seen from the actual measurement that the 1 / 1.28-inch super outsole camera is endowed with high image quality and night shooting capability that does not even need to open the night scene mode. The 8Mp telephoto lens provides a 3x optical zoom to ensure the imaging quality of shooting distant scenes.

Today, most flagship mobile phones are competing for large size and large screens. And there are not many such flagships with one hand. For users who like to hold with one hand, care about lightness and thinness. Pay attention to face value, and like to take pictures. The Huawei P40 with precise positioning and precise pricing is worth experiencing.
