Instead of just racing in hardware configuration, HONOR 400 5G makes itself stand out by integrating many convenient and useful AI functions.

The HONOR 400 5G is a fusion of premium design inspired by HONOR flagships, a modern and efficient mid-range processor, and an operating system with a strong focus on Edge AI. As such, the HONOR 400 5G represents a shift towards a holistic user experience where deep-rooted AI plays a key role.

Specifically, the HONOR 400 5G focuses its resources on three main pillars: a screen with segment-leading display quality and eye protection technology, a camera system with a main sensor with a resolution of up to 200 MP, and an AI ecosystem deeply integrated into both hardware and software. The HONOR 400 5G is not an “all-round” smartphone but a “focused” device. It represents a smart product approach where the balance between end-user experience, marketing power, and manufacturing cost is a top priority.

HONOR 400 5G Design

The HONOR 400 5G adopts a “boxy” design language with both the front and back being flat, combined with a metal frame with flat edges. This choice creates a modern, somewhat angular look, different from the soft curved trend on many competitors and even on the HONOR 400 Pro version.

The “Desert Gold” color version is the aesthetic highlight among the color options of HONOR 400 5G. This color brings a warm, sophisticated feeling and is different from the basic colors. The special feature of this version lies in the frosted texture on both the back and the frame. This finish not only creates a luxurious visual effect but also has high practical value, effectively preventing fingerprints and sweat, keeping the device clean and beautiful.

Ergonomics is one of the strongest points of the HONOR 400 5G. With a thickness of only 7.3 mm and a weight of 184 grams, combined with reasonably rounded corners, the device provides an extremely comfortable and solid grip. The HONOR 400 5G is one of the most comfortable smartphones in its segment to hold – a factor that is often overlooked but directly affects the daily usage experience.

In terms of durability, the HONOR 400 5G is equipped with an IP66 water and dust resistance standard. This standard can help the HONOR 400 5G resist higher pressure water jets than the IP65 standard. This is enough to protect the device from rain or accidental water spills. The lack of IP67/68 shows that HONOR has identified this as a “nice-to-have” feature rather than a “must-have” for its target customer group. This point is one of the most important and calculated sacrifices to keep the product price competitive.

Gorgeous display

The screen is where the HONOR 400 5G clearly excels, and is also one of the main pillars in the company's product strategy. The screen is equipped with a 6.55-inch flat AMOLED panel, capable of displaying 1 billion colors and a high resolution of 1264 × 2736, reaching a pixel density of about 460 ppi, providing sharp and detailed images. The most notable highlight is the maximum brightness (peak brightness) of up to 5000 nits. Note that this "peak" brightness is usually only achieved in a small area of ​​the screen when displaying HDR content, in order to reproduce the most realistic highlights. In actual full-screen usage conditions, the brightness of the HONOR 400 5G is around more than 1500 nits. This is an impressive brightness figure and is among the top in the mid-range segment, ensuring clear visibility even under harsh sunlight.

In addition to the display quality, the HONOR 400 5G also features pulse width modulation (PWM) dimming technology with an ultra-high frequency of 3840 Hz. This is a clear competitive advantage over many competitors, which often use lower frequency PWM on mid-range devices, which can cause eye strain if you are sensitive. The high PWM frequency helps reduce screen flicker at low brightness, providing a significantly more comfortable viewing experience, especially in low-light environments.

In addition, the device also integrates many AI-based eye protection technologies such as AI Defocus Eyecare and AI Circadian Night Display, which automatically adjusts color temperature and display parameters to match the user's circadian rhythm. In addition, Ultra Dark Mode can reduce brightness to just 1.5 nits.

200 MP Camera

The heart of the camera system is a 200 MP main sensor, which comes with very impressive specifications: a large 1/1.4-inch sensor size, f/1.9 aperture, and optical image stabilization (OIS). The sensor size is larger than some flagship models on the market, promising better light capture and a more natural bokeh effect.

In bright conditions, the main camera produces photos with very high detail, vivid colors and wide dynamic range. In particular, the portrait mode, developed in collaboration with the famous French studio Harcourt, produces high-quality images, especially the ability to handle light and create photos with artistic depth. In low light conditions, thanks to the large sensor size, OIS and HONOR's image processing algorithms, the device is still capable of producing good quality photos, retaining details and effectively controlling noise.

The camera cluster also shows a deliberate trade-off strategy, focusing on the center. The device does not have a telephoto camera, so all zoom shots are digital zoom. HONOR also takes advantage of the super high resolution of 200 MP to crop images, applying additional “AI Super Zoom” algorithms when zooming is needed. The quality of digital zoom at 2x to 4x is still quite good and usable thanks to AI intervention, but of course it cannot compare to the optical quality and flexibility of a real telephoto lens.

The HONOR 400 5G can shoot 4K video, but the frame rate is limited to 30 fps. The ultra-wide-angle camera has a resolution of 12 MP, the image quality is average, best used only in well-lit areas.

Performance, battery and charging

HONOR 400 5G configuration is equipped with Qualcomm Snapdragon 7 Gen 3 processor, manufactured on TSMC's 4nm process. This chip has 8 CPU cores, including 1 high-performance Cortex-A715 core clocked at 2.63 GHz, 3 balanced performance Cortex-A715 cores clocked at 2.4 GHz and 4 power-saving Cortex-A510 cores clocked at 1.8 GHz. Graphics are handled by Adreno 720 GPU. Quick test shows that HONOR 400 5G achieved about 860,000 AnTuTu v10 points, higher than Exynos 1580 on Galaxy A56. This shows that Snapdragon 7 Gen 3 is still a chip with enough power and performance for modern smartphones. Although in the mid-range, the performance of Snapdragon 7 Gen 3 easily meets the daily needs of users. Testing with heavy games like Genshin Impact, HONOR 400 5G still responds well with reasonable graphics settings.

HONOR 400 5G uses Silicon-Carbon battery technology, providing higher energy density and better life than traditional Lithium-ion batteries. The battery capacity on HONOR 400 5G is 6000 mAh, in fact, normal use can last up to 2 days before needing to be recharged. The total screen-on time when reaching 5% battery is more than 15 hours. Note that this is a normal usage test, meaning that all connection functions such as WiFi, 4G/5G, speakerphone are still fully enabled... The longer battery life is partly thanks to the support of MagicOS 9 with the "Predictive Scheduling Engine" mechanism. This tool learns user usage habits and intelligently manages system resources.

HONOR 400 5G supports 80W (20V @ 4A) wired fast charging. Actual charging data shows that the device can be fully charged from 0% in just over 40 minutes and reach 80% battery after only 30 minutes of charging. This is a very fast charging speed. However, the device does not support wireless charging, but in return, the box comes with a 100W HONOR SuperCharge charger.

MagicOS 9 and AI features

If the hardware of HONOR 400 5G is a set of strategic choices, then the MagicOS 9 software and the integrated AI ecosystem are the soul, largely determining the user experience and the most important differentiating factor of the product.

MagicOS 9, based on Android 15, shows HONOR's significant efforts in improving the user interface. The transition and opening animations are smooth and intuitive. The biggest and most strategic highlight of the software is the commitment to 6 years of Android OS updates. This commitment helps remove one of the biggest barriers when users consider between HONOR and Samsung, and enhances the long-term use value of the device.

HONOR invests heavily in AI, implementing a multi-layered strategy that combines both Edge AI and Cloud AI to deliver intelligent features. With Edge AI, user interactions and requests are processed directly on the device, leveraging the power of the NPU integrated in the Snapdragon 7 Gen 3. The advantages of this approach are fast response speed, the ability to operate without a network, and most importantly, ensuring privacy because user data does not need to be sent to an external server. Outstanding on-device AI features:

• Magic Portal: One of the most iconic AI features. When users long-press on any content (text, image, address), a toolbar appears at the edge of the screen, automatically suggesting relevant apps based on the context. Users can drag and drop that content into the desired app to perform immediate actions (e.g. drag an address to Google Maps, drag an image to email). This feature significantly speeds up daily workflows. In addition to long-pressing, users can also circle with the back of their finger to activate Magic Portal.
• AI Deepfake Detection: An important security feature that can detect AI-altered, AI-edited videos (deepfakes) in video calls, helping to protect users from increasingly sophisticated forms of fraud.
• Background features: AI algorithms also work in the background to optimize performance and battery life, such as the Predictive Scheduling Engine.

For Cloud AI and Generative AI, these features require a lot of computing power, so they are processed on cloud servers of partners, specifically Google. These features bring unique creative possibilities but also come with limitations: they require a stable Internet connection, processing can take time and importantly, can be expensive. Notable features:

• Image to Video: Using the Google Veo 2 model – Generative AI for video, this feature is capable of turning a still photo into a 5-second short video with natural movements. It is not an exaggeration to say that HONOR 400 5G is the first smartphone to integrate Veo 2, allowing users to experience the easiest and most convenient, especially creative and fun with daily photos.
• AI Outpainting: Allows you to expand the frame of a photo by letting AI automatically “paint” additional details around it, with quite reasonable results.

In addition to the above features, the HONOR 400 5G is also equipped with a practical AI toolkit, including AI Eraser to erase unwanted objects, AI Remove Reflection to remove reflections on glass, along with office tools such as AI Notes (recording and automatically summarizing meetings), AI Translate (real-time translation) and AI Summary (text summary).

Conclude

The HONOR 400 5G is a smartphone that has been crafted with a very clear strategic goal: to bring a near-flagship experience in the most visible and valuable aspects. Users will get good screen quality and high camera resolution at a mid-range price. This is not an attempt to create an “all-rounder” phone that can do everything well, but a “focused” product that accepts calculated trade-offs. Fortunately, these trade-offs are reasonable and it even brings many interesting and unique experiences to users, instead of just competing for configuration.
