Honor 400 Review: Surprising Excellence in Unexpected Features!

June 21, 2025

Test du Honor 400, un smartphone qui excelle où on ne l’attendait pas
Artificial intelligence (AI) is at the forefront of Honor’s strategy, a fact that is reinforced with the new Honor 400. This mid-range smartphone is not only efficient but also incorporates as many AI features as the top-tier high-end mobiles. But will this be enough to make up for its few shortcomings?

At MWC 2025, Honor announced its ambition to become a major player in modern mobility by offering a powerful, yet accessible hardware and AI ecosystem. In line with this vision, they introduced a new mid-range benchmark, the Honor 400.

Priced from 499 euros, it boasts an impressive spec sheet: a Snapdragon 7 Gen 3 SoC, a 6.55-inch AMOLED display, a new battery touted as highly efficient, and a camera block with a 200 Mpx main sensor. Additionally, it features a range of AI-based tools from writing assistance to photo editing and video.

The Honor 400 thus starts at 499 euros, putting it in direct competition with the Xiaomi 14T and the Realme 14 Pro, both of which are solid contenders. However, if the performance meets expectations and the AI integration is as promising as advertised, we might have a new star in the best smartphone market.

Design

The Honor 400 showcases the creativity of its designers. We are presented with a mobile phone that has very sober lines overall, which are enhanced by a meticulous treatment and an eccentric yet successful optical block.

From the front, we see a mobile that’s very much in line with modern times. It features a 6.55-inch AMOLED screen with a central punch hole at the top. The black borders are thin but still visible. They’re not excessive and are well-balanced, avoiding an oversized chin.

Like almost all current smartphones, it features flat metal edges. It’s clean, feels nice to the touch, and on the right edge, you’ll find the physical buttons for volume control and power. They are very well positioned: you won’t have to stretch or bend your thumb too much to switch from one to the other.

With dimensions of 156.5 x 74.6 x 7.3 mm, it offers a fairly compact size, and even those with smaller hands will enjoy using it. Its weight of 184 g is not excessive and is well distributed, avoiding any imbalance in the hand.

Turning to the back, we see a beautifully flat surface with a slightly satin visual finish. The texture is very pleasant in gold — it is also available in black — and just as nice to the touch. The device does not slip, but be careful on very hot days if you’re not using a case.

The camera block is a stylish touch that transforms a standard smartphone into an attractive piece. It has an unusual shape, with golden edges, just like those of each lens. It features a main sensor of 200 Mpx, accompanied by a second 12 Mpx sensor. We can only commend the aesthetic work of the designers: this single element adds real personality to the product. However, when placed flat, the optical block creates a noticeable imbalance. It’s still possible to type a message, but it won’t be very smooth.

The level of finish is very good. The Honor 400 is also certified IP65 and Drop & Crush Resistance by SGS. It’s not an all-terrain phone, but it’s durable enough to withstand the rigors of everyday life.

Screen

Honor equips its latest smartphone with an AMOLED panel at 2736 x 1264 pixels, which gives us a pixel density of 446 ppi: thus, we enjoy a beautifully fine display. There’s no LTPO panel, but it does have a step adaptive refresh rate. The mobile can automatically switch between 60 Hz and 120 Hz.

The Honor 400 offers two color display modes: Normal and Vivid. According to measurements taken with our probe and the CalMAN Ultimate software by Portrait Displays, the former offers the most natural rendering.

We measured a Delta E of 3.4, slightly higher than the reference value set at 3. It’s honest, but not perfect, just like in HDR where it follows the same pattern. This rendering is associated with a color temperature of 6434 K, compared to 6500 K for the standard. The final result remains quite natural, even if some shades appear a bit flattering. At this price level, the Honor 400 performs very well. The screen covers 103% of the sRGB space, 68% of the DCI-P3, and 47% of the BT.2020. It displays slightly fewer color nuances than some direct competitors.

In terms of brightness, we’re looking at a rather generous product. We measured 1456 nits in SDR, which allows comfortable use in all situations. Even in full sunlight, the screen remains readable, without necessarily having to squint. In HDR, our probe measured 1559 nits. The extra brightness isn’t huge, but it’s enough to enjoy HDR content in a dim or bright environment. In full daylight, however, it’s a bit tight.

Performance

At the heart of the Honor 400, we find a Snapdragon 7 Gen 3, along with an Adreno 720 GPU, 8 GB of LPDDR4X RAM, and either 256 or 512 GB of UFS 4.1 storage. A robust configuration that has already proven itself in many smartphones and remains relevant, even compared to a mobile equipped with a Snapdragon 7s Gen 3.

As our benchmarks show, this Honor positions itself very well against competitors in the same price segment. In terms of raw power, it’s not the last by any means, and it stands out in AnTuTu, for example, or in 3D benchmarks. Moreover, at less than 550 euros, it is one of the few smartphones capable of handling local AI tests. In use, we enjoy a fluid product, which offers quality performances both under Android and with apps, not to mention quite fast multitasking.

In the gaming domain, this Honor 400 does quite well. On Fortnite, in Epic mode, the framerate oscillates between 50 and 60 fps. However, on average, we’re closer to 55 fps when nothing disturbs your gaming session. As soon as the screen gets too busy or enemies appear, it drops to 50 fps, or even a bit less.

For Genshin Impact, the same observation applies: to play at 60 fps, you need to sacrifice some graphic quality. Otherwise, 45 to 50 FPS will be the norm for you.

However, on Call of Duty Mobile, the Ultra graphic mode allows reaching a nearly constant 60 fps. At high refresh rates, Fortnite (in 90 fps mode) and Call of Duty (in 120 fps mode), both in low graphic quality, we never reach the promised framerates. They oscillate between 40 fps and 65 fps for Fortnite and 75 fps to 90 fps for COD.

A GameCenter allows optimizing performance and boosting the processor. However, the difference in gaming usage is small, and the battery is much more solicited.

Honor has managed to control the heating of its mobile well. Thus, after long gaming sessions, the smartphone reaches a maximum of 40°C. It heats up, but not enough to make real use uncomfortable. Moreover, facing charging tests, the processor undergoes a slight loss of performance, on average from 12 to 15%, with rare drops to 22%. That’s very decent.

Software

Honor equips its Honor 400 with Magic OS 9 and Android 15. This pair has already proven itself, offering an interface that is both pleasant to use and swift. Moreover, it offers numerous customization options. Not to mention an equivalent of Dynamic Island, although still a bit limited.

With this Honor 400, the manufacturer applies to a mid-range product its AI strategy. And this mobile is more than richly endowed, as well — if not better — than some competitors costing twice as much. Thus, we have at our service:

  • AI Writing, which can both generate and summarize text.
  • Magic Text, which serves to copy text from an image.
  • AI Subtitle, which applies — as its name suggests — subtitles to your videos, as well as during voice calls.
  • AI Translation, which provides access to real-time translation.
  • Big novelty: AI deepfake detection. During a video call, this function is supposed to detect images generated by artificial intelligence.

With the exception of the latter, we have tested each function, and it must be admitted that they prove effective. If you add to this the presence of Gemini and Circle to Search, you get an accessible mobile… that has everything of a great in the field of AI.

And it doesn’t end there: AI Suggestion recommends the best apps according to your actions or habits, whether it’s handling text, images, or web links.

On the imaging side too, Honor brings out the heavy artillery with:

  • AI Eraser: allows removing unwanted objects or people from your snapshots.
  • AI Remove Reflection: removes reflections on photos taken through glass. Interesting, but still perfectible.
  • AI Upscale: automatically adjusts the format of your images.
  • AI Cutout: a suite of tools to modify your photos, for example by changing the background.
  • AI Face Tune (Eyes Open): detects closed eyes to avoid “failed” photos.
  • AI Image-to-video: transforms a series of photos into short videos.

It’s hard to get more complete, and there are still several small practical functions to discover daily.

And you will also get acquainted with the bloatware and some intrusive ads shipped with the Honor 400. Nothing excessive, nothing that cannot be settled in a few minutes of uninstallation… but still as unpleasant at startup.

Good point: the update policy is solid, with six years guaranteed for Android, and as much for security patches. We are not very far from the seven years offered by Samsung or Google. Bravo.

Photo

Honor here relies on a duo of sensors to compose its optical block. Thus, we have at our disposal:

  • A 200 Mpx wide-angle with an aperture of f/1.9
  • A 12 Mpx ultra wide-angle associated with an aperture of f/2.2

We are facing a classic configuration in this price range. However, the competition often offers in addition a macro sensor. Honor compensates by using the ultra-wide-angle sensor to perform macros. However, we would have preferred a telephoto lens, as offered by the Nothing Phone (3a) Pro.

Wide-angle

The main sensor captures very good level shots in broad daylight. Thus, we have very legible images, with particular care given to micro-details. Whether it’s a mandarin or a stone aqueduct, one can really feel the texture of the materials. However, it must be nuanced, because a slight digital smoothing is present, and it becomes more aggressive as one moves away from the foreground. The level of detail then drops, but this is only noticeable if one zooms into the image or if one looks at the photos on a large screen.

Brightness is managed with accuracy, provided that focus is manually achieved on the screen. Otherwise, there are sometimes misses, but rarely enough to completely spoil a photo. The contrasts are quite fine, which contributes to a good rendering of details. The colorimetry is beautiful, natural, even if it sometimes tends to saturate. This happens especially when brightness decreases: the algorithms seem to want to compensate with more flattering colors.

At night, the main sensor proves quite valiant, but it is not cut out for all situations. Thus, when urban lighting is absent or weak, the rendering is unbalanced. Although it manages to capture a good amount of light, it is at the level of digital processing that the problem lies. The foreground benefits from beautiful details — one can even distinguish the veins of some leaves —, but the further away one gets, the more aggressive the digital smoothing becomes. We also note the appearance of quite marked digital noise, especially in the less bright areas. This is the case here on the right of the bridge, which clearly lacks definition.
