Nonetheless the perfect small-sized telephone available on the market in 2023, the Asus Zenfone 9 delivers glorious efficiency and extremely succesful digicam {hardware}. Nonetheless, there are a number of minor gripes that permit it down, together with charging velocity, picture processing, and its thickness.

Design and Display screen

  • It’s a small however thick brick
  • Uncommon roughened-but-soft end
  • Daring and brilliant OLED show with good out of doors visibility

The Asus Zenfone 9 is an unusual-looking telephone. It has a small footprint, however the digicam lenses on the again are large, just like the eyes of a kind of yellow Minions characters. 

Additionally it is on no account skinny at 9.1mm thick. And that doesn’t look like the measurement of probably the most sticky-outy digicam lens both, simply the principle physique. 

The Zenfone 9 is mild and never a handful, however it’s not fairly modern and slender like a number of the different small telephones you may look into. Nonetheless, this suits with Asus’s type. It has by no means been a family telephone model within the US, UK, or Europe, and its largest successes have arguably been fashions such because the ROG Telephone 6 Professional that might attraction to the nerdy crowd who may like its RoG gaming PCs.

The rear end is uncommon right here too. On the value you may hope to see glass, maybe aluminium, however Asus used a “polymer” within the Zenfone 9.  I often take this as a advertising and marketing spin on “plastic” however the Zenfone 9’s rear does have an uncommon really feel to it. It’s softer than a daily plastic, however isn’t rubberised. 

I suppose the purpose is to offer the Zenfone 9 a kind of furitistic industrial really feel, one thing that isn’t glass or aluminium however doesn’t really feel low cost. Nonetheless, I do have some worries about the way it will maintain up long run. You’ll be able to put a mark in it with a comparatively mild graze of a fingernail. And whilst you can rub out inconsistencies within the end, easy-wear surfaces hardly ever age that nicely. 

Asus does bundle in a rear cowl, however it’s easy plastic and doesn’t really feel pretty much as good. Nonetheless, it’s best to most likely use it.

There are lot of nice options to be discovered on this telephone’s {hardware}. For starters, it has a headphone jack; a rarity as of late. It additionally has stereo audio system, ones with glorious efficiency for a smaller telephone. There’s one driver above the display screen, and one other on the backside, and they’re roughly matched, tonally. Generally you get a bassy speaker and a tinny one, however that’s thankfully averted on this case. Most quantity is nice, and there’s a good substance right here. 

The Zenfone 9 is water-proof to IP68, the very best score you’ll discover in a “regular” telephone, and there’s a quick fingerprint on the aspect. The show glass is top-tier Gorilla Glass Victus, so it’s constructed to be proof against scratches.

This can be a properly designed and weird telephone, however one potential downside that I can see is the corners of its plastic rear panel turning shiny by put on.

The Asus Zenfone 9 is a smaller telephone, so naturally doesn’t have a large display screen. It’s a 5.9-inch OLED panel, a flat one with decision of 2400 x 1080 pixels. The display screen borders are small, and the panel is flat. It’s nonetheless the smallest panel round in 2023, with most different Android makers seemingly shunning something lower than 6.1 inches.

There’s nothing right here to instantly sign you spent extra money on the Zenfone, however that is largely as a result of nearly all £200-plus telephones have glorious screens as of late. For instance, you will get comparable specs for much much less cash in mobiles just like the Xiaomi Redmi Notice 11 Professional.

Asus claims the Zenfone 9 can attain 1100 nits of brightness. However does it? In a usually lit room the telephone will head as much as round 442 nits of brightness. And in its turbo-charged excessive brightness mode it may well hit 805 nits. This can be a very wholesome determine, sufficient to make outside visibility largely a non-issue. The excessive brightness mode will have interaction robotically while you head outside on a brilliant day. 

It’s a handsome, colour-rich and contrasty display screen. The small dimension makes it simpler to stretch your thumb throughout too, and Asus helps you to use the Zenfone 9’s energy button to tug down the notification window in case you like, because of a function referred to as ZenTouch, the place the capacitive properties of the fingerprint reader permit it to double as a contact floor. 


  • Nice-quality {hardware} throughout the board
  • Good normal picture high quality together with at evening
  • A number of the finer factors of picture processing could possibly be improved

You’ll be able to’t miss the Zenfone 9’s cameras, sitting proper there on the again behind a pair of coke bottle glasses. As you may inform from there being simply two cameras, Asus has not loaded up this telephone with sensors simply to make it look sensible. 

The first digicam has a 50MP IMX766 sensor, a big chip that Asus has used earlier than within the Asus RoG Telephone 6. OPPO additionally employed it within the top-tier Oppo Discover X5 Professional. The ultra-wide digicam makes use of the Sony IMX363, which was the brains of the principle digicam within the much-lauded Pixel 5. And the selfie digicam makes use of the Sony IMX663. 

Asus was clearly going for it with the Zenfone 9 digicam, utilizing all-Sony sensors when cost-conscious fashions usually throw in some Omnvision or Samsung {hardware}, as a minimum. Nonetheless, in one other sense Asus has held again; the Zenfone 9 has no zoom digicam. Becoming one in a telephone this small can be a problem, and would no double improve prices dramatically, but it surely’s the one lacking half of what’s in any other case a powerful set of bits of {hardware}.

Asus makes use of A-grade sensors, and whereas it doesn’t fairly have the software program to keep away from criticism totally, the tip end result remains to be a super-capable and fun-to-use digicam. 

The primary nice Zenfone 9 function is how the unusually high-quality ultra-wide digicam means there’s no apparent high quality compromise while you change lenses, even when taking pictures in poorer mild. Degradation of the picture on the corners is best than common, lens distortion is robotically corrected, and ultra-wide photographs maintain as much as shut scrutiny fairly nicely. 

A high-quality ultra-wide with geometric distortion correction means it’s not at all times instantly apparent which digicam any shot was taken with (and that’s a very good factor), as you may see from the images under:

“Gimbal” stabilisation is Asus’s second star function. This refers to super-charged optical picture stabilisation, matched with software program stabilisation. It could possibly compensate for as much as three levels of movement, and you may clearly see the lens shifting when the digicam app is open. 

That is most helpful when taking pictures video, as stabilisation simply isn’t that obligatory throughout the day, and at evening software program does quite a lot of the legwork. Whereas I don’t discover the stabilisation miles higher than that of some flagship telephones, it’s at that degree. And its hardware-based nature means even the Zenfone 9’s prime taking pictures mode will get some type of stabilisation — that’s a whopping 8K decision (at 24fps) on this case. 

The Zenfone 9’s video is robust throughout the board. 4K video at 60fps is my most well-liked mode. It’s easy, sharp and clear. You’ll be able to even shoot HDR video in case you drop all the way down to 30fps. 

1080p footage doesn’t look overly gentle, because it typically can do in telephones. And whereas I don’t assume the 8K mode is price utilizing that always over 4K because of the decreased movement readability, and elevated picture and color noise, the stabilisation makes it extra usable than loads of 8K modes I’ve used up to now. Good job, Asus.

Let’s head again to stills. The Asus Zenfone 9 can deal with just about any state of affairs. It maintains foreground readability when taking pictures into the solar. At evening the high-quality sensor and OIS repay, netting you clear and clear pictures whether or not you utilize the devoted evening mode or not. They don’t take an arduous period of time to seize both. 

Perceived element from each the usual and ultra-wide lenses is nice and the Asus Zenfone 9 is best at preserving highlights in lots of scenes than the Motorola Edge 30 Fusion I got here from utilizing every week or so forward of this evaluation.

There are a number of quirks, principally associated to processing. The Asus Zenfone 9 doesn’t have class-leading color dealing with. Whereas tones don’t look comically oversaturated, the telephone will at instances clip color channels when, for instance, taking pictures a brilliant crimson flower. 

Have a look at pictures all the way down to the pixel degree and also you’ll discover the Zenfone 9 has much less natural-looking element processing than an iPhone, Pixel or one of many best Samsungs. I believe Asus’s has tuned the “AI” texture rendering too arduous. Look shut at a gravel path and the patina of its floor will typically look “made up”. As a result of it kinda is. And much away bushes and leaves received’t look as pure as they might do, shut up. 

That is the sort of processing type Samsung has largely weaned itself off over time, and Asus’s type nonetheless has some maturing to do. Nonetheless, this isn’t all that evident till you look shut, so is barely going to be a serious difficulty while you begin cropping into pics.

The side-effects of the HDR type are going to be extra apparent. This telephone tries rather less arduous to retain excessive highlights in very excessive mild distinction scenes than many. You’ll be able to see this while you shoot immediately Into the solar. The place some telephones will render the solar as somewhat dot, it turns into an even bigger white splodge by the Zenfone 9. The remainder of the scene will usually look nice, with exemplary mid-tone readability and fairly good dealing with of color in these excessive situations. However, once more, Asus’s software program isn’t fairly top-tier. 

There’s additionally a wee little bit of shutter lag within the Zenfone 9. It’s not an ideal digicam, and a few of its heights aren’t that far off these of the cheaper Pixel 6a or OnePlus Nord 2T. Nonetheless, the constant excessive degree of high quality within the {hardware} is spectacular. 

The Zenfone 9’s selfie digicam is nice too, for instance. It could possibly take care of poor mild and backlight scenes whereas retaining quite a lot of tremendous element. And it may well’t damage than the selfie digicam has comparatively giant 1.22 micron sensor pixels. 


  • Highly effective processor with no better throttling than bigger fashions
  • Good for gaming, though somewhat small for the job
  • Unfussy customized interface

The Zenfone 9 ran Android 12 out of the field at launch with a customized interface on prime, although it acquired the replace to Android 13 in 2023.

At first look I believed its app drawer regarded a bit cramped, somewhat text-heavy; however that is actually only a knock-on impact of the display screen dimension. 5 columns of icons right into a 5.9-inch display screen is the next density than your eyes could also be accustomed to, and it may well take a little bit of getting used to.

I’m happy to report that there’s nothing too offensive happening right here, software-wise. The interface is mild sufficient to point out off Android options like the colorful function toggle blobs. You’ll be able to alter the color of those — issues just like the Wi-Fi toggle button — to vary the look of your telephone somewhat. 

Lots of the preliminary Asus visible flavour is de facto simply all the way down to the moderately daring Zenfone 9 preinstalled animated wallpaper. Altering it to one thing static, much less abrasive, takes the sting off and makes the Zenfone really feel a lot nearer to the expertise of utilizing a Pixel telephone.

The Asus Zenfone 9 had the perfect telephone processors on this planet on the time of launch. It’s the Qualcomm Snapdragon 8 Plus Gen 1, a follow-up to the “non plus” Snapdragon 8 Gen 1. 

This can be a higher-clocked chipset, however can also be made utilizing a distinct manufacturing course of that Qualcomm claims dramatically improves energy effectivity. After being initially impressed by the unique Snapdragon 8 Gen 1’s benchmark outcomes, I believe it has proved to be a little bit of a dud. It causes quite a lot of machine heat-up in each telephone I’ve used, leading to thermal throttling which means you received’t at all times get dramatically higher real-world gaming outcomes after some time than a mid-tier chipset just like the Snapdragon 870 or MediaTek Dimensity 1300. 

The place a lot of the Snapdragon 8 Gen 1 telephones I’ve used find yourself with underneath half their peak gaming energy after some time, the Asus Zenfone 9 holds on to 75.2% in accordance with 3D Mark’s Wild Life Excessive benchmark. Asus does appear to have tailor-made this telephone for efficiency, although, because the aluminium sides did get fairly toasty by the tip of this 20-minute take a look at. 

Peak graphics efficiency can also be round 27% increased than that of a Snapdragon 8 Gen 1 telephone just like the Galaxy S22 Extremely. It nonetheless can’t match the iPhone 14’s A16 Bionic, although. However that telephone is £150 greater than the unique value of the Zenfone 9. Nonetheless, it’s going to sail by any recreation you may select to play — though I’d recommend contemplating a larger-screen telephone if you’re cellular gaming obsessive.

It’s price noting that the Snapdragon 8 Plus Gen 1 has been changed by the even newer Snapdragon 8 Gen 2 utilized by many 2023 flagships, however you’ll be hard-pressed to see a distinction in efficiency in real-world situations, making it simply as tempting in 2023 because it was in 2022.

  • Charging is on the sluggish aspect 
  • First rate stamina for a small telephone
  • No wi-fi charging

The Asus Zenfone 9 has a 4300mAh battery, an ideal tremendous capability for its dimension. However it’s proven up by the Sony Xperia 10 IV, which inserts a 5000mAh battery right into a narrower and thinner (if taller) shell. 

Its charging velocity can also be fairly poor in comparison with that of the opposite Chinese language manufacturers you may head to with this a lot cash to spend: OnePlus, Xiaomi and so forth. The Zenfone 9 features a 30W charger however, utilizing an influence meter to examine the facility draw, the speed heads in every single place throughout a cost cycle.

The Asus Zenfone 9 takes 84 minutes to achieve 100% cost, and 33 minutes to hit 50%. It’s a bit garbage when you think about a full cost of the OnePlus 10T takes lower than 20 minutes. 

Precise battery life is a non-event in evaluation phrases. It’s not good, it’s not dangerous. I discovered I can get by a day, no downside, however not with sufficient cost to make plugging the telephone in, say, each different day a viable proposition. 

It’s nowhere close to as long-lasting because the Sony Xperia 10 IV, a telephone I in any other case don’t like almost as a lot because the Zenfone 9, and is nearer to the OnePlus Nord 2T in stamina phrases.

The Asus Zenfone 9 is a traditional pocket powerhouse Android telephone, combining a small body with top-tier energy, superior digicam tech and high quality parts all through.

Whereas the telephone performs nicely in nearly each space, a number of finer factors like digicam processing, charging velocity and its thickness are small disappointments

Last Ideas

The Asus Zenfone 9 remains to be the perfect small “pocket rocket” telephone for demanding consumers, even nearly a 12 months after its preliminary launch. It’s probably the most compact Android you’ll discover, it’s not overpriced, could be very highly effective, it appears to be like distinctive, and Asus makes use of high-quality digicam {hardware} throughout the board. 

There are a number of points. I’m not persuaded the rear end goes to age nicely. Asus’ digicam processing isn’t as refined as the perfect. Charging velocity will not be nice. And a few received’t like that the Zenfone 9 is dramatically chunkier than, say, the iPhone SE. 

Nonetheless, it’s a singular telephone, not fairly like the rest on the market proper now. And that’s price celebrating in itself.
