Honor 400 Pro: Two-minute review
‘Flagship killer’ would perhaps be too strident a term to apply to the Honor 400 Pro. Rather, it seeks to subtly undermine the premium crowd with competitive specifications and a slightly lower asking price.
This is a well-built phone made of flagship-grade materials, with the kind of IP68/IP69 dust and water resistance rating that puts many a full-priced handset to shame. Its 6.67-inch OLED display, too, is about as bright, sharp, and accurate as you could reasonably expect.
While you won’t be getting the absolute best performance the smartphone market has to offer, you simply won’t notice that Honor has opted for last year’s top processor unless you take a glance at the spec sheet. The 400 Pro performs very smoothly indeed.
The headline feature here is an all-new 200MP main camera, which captures good photos in a range of lighting conditions. You also get a decent dedicated 3x telephoto camera, which can be further boosted through the use of AI.
Another impressive AI camera trick is Image to video, though its ability to turn stills into brief videos is a party trick that probably won’t see much practical use beyond showcasing the latest artificial intelligence gimmick.
No matter – the Honor 400 Pro is a thoughtfully balanced phone built on solid specifications, which includes a larger-than-average 5,300mAh battery and speedy 100W wired charging support. You also get 50W wireless charging, though both speeds are reliant on you having the necessary charger to hand.
Honor’s Magic OS 9.0 continues the brand’s slightly tiresome obsession with iOS, and it remains a somewhat busy UI. However, it’s also fast and flexible, and Honor’s new six-year update promise is one of the best in the business.
All in all, the Honor 400 Pro is part of a compelling group of in-betweener smartphones, offering less compromise than even the best mid-range smartphones while still costing much less money than your average flagship.
It’s not unique, nor is it without its flaws, but it’s a very accomplished option for those willing to leave the usual suspects behind in pursuit of a bargain.
Honor 400 Pro review: price and availability
- Costs £699.99 in the UK
- Released May 2025
- No availability in the US or Australia
The Honor 400 Pro was launched globally, alongside its brother, the Honor 400, on May 22, 2025. It won’t be receiving a launch in the US, as is customary from the brand, and there are no plans for Australia at the time of writing.
Pricing for the sole Honor 400 Pro model stands at £699.99 (around $930 / AU$1,450), which isn’t a figure we see all that often. This pitches it well above the Google Pixel 9a and the Samsung Galaxy A56 (both £499), and just short of the Google Pixel 9 and Samsung Galaxy S25 (both £799).
This isn’t quite a full-on flagship phone, then, but it’s also far too expensive to be classed as a mid-ranger. It’s one of those ‘affordable flagship’ phones like the OnePlus 13R, the Samsung Galaxy S24 FE, or the Nubia Z70 Ultra.
Incidentally, an even cheaper version of the Honor 400, the Honor 400 Lite, launched on April 22 at a cost of £249.99.

Honor 400 Pro review: design
Image 1 of 2
- Silky matte glass back
- Unusual curved-trapeze camera module
- IP68 & IP69 dust and water resistance
With the Honor 400 Pro, Honor has dropped the distinctive Casa Milá-inspired camera module of the Honor 200 Pro in favor of a kind of rounded trapezium shape (a trapercle?). It’s a little wonky-looking, though I quite like the unorthodox camera configuration.
Otherwise, Honor has retained the basic look of its affordable flagship range – unlike the regular Honor 400, which has contracted a serious case of the iPhones.
This means that the Honor 400 Pro retains its gently rounded look, with 2.5D glass to the front and back – the latter in a pleasingly silky-to-the-touch finish. The aluminum frame, too, curves around gently, resulting in a phone that sits comfortably in the hand.
These curves also serve to disguise the fact that the Honor 400 is a fairly big phone, with a thickness of 8.1mm (the Honor 400 is 7.3mm) and a relatively heavy weight of 205g (vs 184g).
This time around, Honor has fitted its almost-flagship with both IP68 and IP69 certification. That’s quite an advance on the Honor 200 Pro, which only managed an IP65 rating.
The Honor 400 Pro is available in just two colors: Lunar Grey and Midnight Black. Not the most inspiring selection, it has to be said, but they do look nice and professional, which is kind of the name of the game here.
Honor 400 Pro review: display
Image 1 of 2
- 6.7-inch quad-curved 120Hz OLED display
- 3,840Hz PWM dimming
- 5,000 nits peak brightness
Honor has really knocked it out of the park with the displays in the Honor 400 range this year. In the Honor 400, you’re getting a 6.7-inch OLED with a just-so 2800 x 1280 resolution and a 120Hz peak refresh rate.
That’s fractionally smaller than last year’s 6.78-inch screen, but I defy anyone to portray this as meaningful. Not when the peak brightness has been boosted from an already-excellent 4,000 nits in the Honor 200 Pro to 5,000 nits here.
This top-end figure applies to limited HDR scenarios, of course. With autobrightness switched off, I recorded a maximum brightness of around 600 nits. That’s decent enough, though it’s about half what the Pixel 9 can manage.
Color accuracy is superb, at least when you drop the slightly over-the-top Vivid color mode and select Normal instead.
The Honor 400 Pro display also supports an elevated PWM dimming rate of 3840Hz, just like the Honor 200 Pro before it. This helps reduce eye strain by lowering flicker at lower brightness levels. That’s something Samsung and Google continue to overlook.
The main differences between this screen and the Honor 400’s relate to small aesthetic choices. The Pro Display curves away at the edges, though this didn’t interfere with content in any way, nor did it lead to any unintended presses.
Slightly more bothersome is the longer display notch, which crams in depth-sensing capabilities at the expense of a little real estate. If you like to take your video content full screen, you’re more likely to be bothered by this, but it didn’t trouble me too much.
Honor 400 Pro review: cameras
- 200MP main (f/1.9)
- 50MP 3x telephoto (f/2.4)
- 12MP ultra-wide macro (f/2.2)
Honor has really ramped up its camera offering with the Honor 400 series this year. The headline event for the Honor 400 Pro is a new 200MP AI Main Camera, which packs a large 1/1.4-inch sensor, an f/1.9 aperture, and OIS.
We’ll get into the ‘AI’ part of that main camera soon enough, but at a basic level this camera takes sharp, contrasty shots in most situations. You can choose from three basic looks depending on whether you want your shots to look natural, punched up for social media, or to take on a certain artful film camera aesthetic.
Shots from this main sensor are slightly less impressive here on a £700 phone than they are on the £400 Honor 400, which shares the same component. There’s simply a lot more competition at this level. With that said, they’re still more than serviceable.
Unlike the Honor 400, this main sensor isn’t pulling double duty to provide all of your zoomed shots. There’s major assistance on that front from a dedicated 50MP telephoto camera, utilizing a Sony IMX856 sensor and aided by OIS, which grabs nice, sharp shots at its natural 3x zoom length and usable shots at 6x or even 10x.
Beyond that, you’ll find too much noise for this to be a viable option, though Honor’s AI image enhancement technology is one of the most impressive around. Stray beyond 30x, and the phone should offer you the chance to activate AI assistance. Head back into the picture after shooting and, after a minute or so of processing time, you’ll be given a much clearer shot.
The results here can vary wildly in effectiveness, and it certainly does no favors to the human face, while it can really miss the target with some fine details, particularly at the 50x maximum range. However, there’s no denying that this can turn out much improved hybrid zoom shots given the right subject and shooting conditions.
What I will say is that this 3x telephoto camera does change the tone of the shots from the main sensor. Moving from 2x (which crops in on the main sensor) to 3x sees a slightly jarring shift from a more natural look to a more vivid, dare I say exaggerated one. It’s not ruinous, but you don’t get the seamless transition of the truly top-level flagship phone cameras here.
The 12MP ultra-wide is the weakest camera of the three, bringing with it a marked drop-off in detail and contrast. Still, it remains a viable camera.
Going back to the matter of AI, perhaps the most attention-grabbing – if not exactly useful – feature of the Honor 400 Pro’s camera is Image to video. The Honor 400 series is the first to utilize this Google AI-driven feature, which essentially turns any normal still photo (it doesn’t even need to have been taken on the phone) into a five-second mini-video.
As with so many AI-driven features these days, the results aren’t universally brilliant, but some prove to be alarmingly convincing.
Using one shot that was sent to me of a chicken and a cat facing off under a table, this AI tool caused the chicken to strut forward while the cat casually twitched its ears. Another chicken scuttled in from off camera, while a second cat was revealed to be lying down behind that original chicken. Neither of those last two creatures even existed in the original shot.
It’s undeniably impressive, and even a little scary. But I have to ask myself when I’d use this feature beyond showing off the power of AI to my friends and family. So far, I’ve got nothing.
The 50MP front camera takes decent selfie shots, aided by an additional depth sensor for better portraits with nicely blurred, clearly delineated backgrounds.
Video capture extends to 4K and 60fps, which is another way in which the Pro stands out from the Honor 400 (which only hits 4K/30fps).

Honor 400 Pro review: performance
- Snapdragon 8 Gen 3 chipset
- 12GB RAM and 512GB storage
Performance has ostensibly taken an incremental bump over last year’s Honor 200 Pro. Out goes the stripped-back Snapdragon 8s Gen 3, in comes Qualcomm’s full-fat Snapdragon 8 Gen 3.
However, that Snapdragon 8s Gen 3 chip turned out to be much less capable than its name initially suggested, dropping behind Snapdragon 8 Gen 2 in graphical terms.
What we have here, then, is a phone that performs as well as the 2024 flagship crowd. That works out to be a pretty good level for a £700 phone, and indeed, this is the same component that runs the excellent OnePlus 13R. It also means that the Honor 400 Pro comfortably outperforms the entire Pixel 9 range.
Benchmark results are precisely what we’ve come to expect from this well-established chip, as is gaming performance. Genshin Impact will run fluidly on high settings, while demanding console racer GRID Legends speeds by at an appreciable lick.
The existence of the Nubia Z70 Ultra and the Poco F7 Ultra means that the Honor 400 Pro isn’t top of its weight class. Both of those rivals run on the superior Snapdragon 8 Elite chip, and only charge £649 for the privilege. However, Honor’s phone remains a very capable runner, backed by 12GB of RAM and a generous 512GB of internal storage.
Honor 400 Pro review: software
- Magic OS 9.0, based on Android 15
- Six years of OS updates and security patches
The Honor 400 Pro runs Magic OS 9.0, which is the company’s bespoke Android 15 skin. It’s the same basic software provision as that of the Honor Magic 7 Pro.
I think I can speak for the extended TechRadar family when I say that Honor’s UI isn’t our favorite. Bloatware continues to blight it, with unwanted preinstallations of Booking.com, Temu, ReelShort, and much more besides. Honor itself gives you duplicate App Store and email apps, and a stack of its own tool apps.
While this is a take on Google’s Android, Honor seems to be far more inclined towards Apple’s iOS. Everything from the split notification pane to the Settings menu and the lack of a dedicated app tray (by default) speaks to a fondness for Apple’s mobile operating system. Even the icons and the Settings menu are designed in a way that will be familiar to anyone who’s used an iPhone recently.
You even get a version of Apple’s Dynamic Island, here called Magic Capsule, which offers little widget-like bubbles of information around the extended selfie notch. With that said, it’s an undeniably useful way of surfacing media controls, timers, and the like, and Honor is far from the only Android manufacturer to follow Apple’s lead in this way.
Indeed, Magic OS, for all its clutter and bloat, remains a very functional and extremely snappy UI. Magic Portal is a power user’s dream, providing an easy way to drag text and images between apps. The knuckle gesture shortcut for circling text in this way isn’t 100% reliable, but you can get used to it.
Topping off Honor’s somewhat mixed software provision is a commendably strong commitment to six years of OS updates and security patches. Only Google and Samsung do this better with their respective seven-year promises.
What’s more, Honor has committed to providing an Android 16 update before the end of 2025, which isn’t something you see too often.
Honor 400 Pro review: battery life
- 5,300mAh silicon-carbon battery
- 100W wired charging
- 50W wireless charging
Honor seems intent on pushing battery and charging technology in its phones. The Honor 400 Pro gets a meaty 5,300mAh battery, which falls comfortably north of the 5,000mAh average – if not quite as far north as the OnePlus 13R and the Nubia Z70 Ultra, both of which hit the giddy heights of 6,000mAh.
It’s sufficient to get the Honor through a full day of heavy use with remaining charge to spare. Indeed, a moderate day with around four hours of screen-on time left me with more than 60% left in the tank. Average use in a fairly consistent network environment will get you two days on a single charge, no problem.
Talking of charging, Honor goes harder than it probably needs to here. There’s 100W wired charging support that’s seemingly able to get you from empty to 51% in just 15 minutes.
I say ‘seemingly’ because Honor, like most modern manufacturers, no longer bundles in a charger. Without one of Honor’s SuperCharge chargers to hand, I was unable to put those claims to the test.
Ditto for the claim of 50W wireless charging support. It’s good to see, but you’ll need one of the brand’s own SuperCharge wireless chargers to hit that maximum speed.
