Asus Zenfone 8 evaluation: Scorching little quantity

(-) – Asus is taking a unique path to a lot of the Android smartphone house with the Zenfone 8. Slightly than making an enormous cellphone, packing it with tech and asking you to pay a great deal of cash for it, it has gone compact.

The Zenfone 8 joins the likes of the Sony Xperia 5 II in providing flagship {hardware} in a compact type and is, as such, one thing of a rarity in trendy smartphones.

Design and construct

  • Dimensions: 148 x 68.5 x 8.9mm / Weight: 169g
  • Steel body, Gorilla Glass Victus back and front
  • IP65/68 water safety

The transfer to a extra compact mannequin could be enticing to these fed up with having to purchase a giant cellphone to get the most recent {hardware}.

Certainly, it is instantly enticing to these wanting a cellphone that is extra pocketable, and slipping this right into a jersey pocket when heading out biking is an actual pleasure: there is not any feeling that it is going to leap out of your pocket while you hit a bump as there’s with bigger, heavier, gadgets.

The truth that it additionally gives IP65/68 safety provides it extra rounded enchantment for outdoorsy sorts who won’t need to be carrying an enormous slab of a cellphone of their pocket when out strolling the hills or working, for instance. Rain, sweat and a dunk in a puddle isn’t any drawback for this little machine.

With a metallic body and Gorilla Glass Victus each back and front there’s some safety from scratches too, with a luscious matte frosted end to the rear that feels nice and avoids the worst of the fingerprints. Nonetheless, the design is not probably the most eye-catching, it is just a bit boring to take a look at. There is a onerous case within the field to supply safety, but it surely’s not probably the most grippy.

The entire Zenfone 8 goal is to be higher suited to single-handed use and that is actually achieved, whereas Asus has additionally included a 3.5mm headphone socket alongside stereo audio system, so there is a feeling that not an excessive amount of has been compromised in going small.

Which means it is a nice bundle for these wanting a compact cellphone, however we do surprise how many individuals on the market need a compact flagship cellphone. Apple has reportedly not had a storming success with the iPhone 12 mini (though rumours cannot at all times been believed), whereas purchaser demand has been for bigger gadgets – which is why the market is dominated as such.

One fascinating element within the Zenfone 8 is that Asus has included an LED subsequent to the USB-C port. This serves as a notification gentle, illuminating while you connect with a charger and so forth.

Asus additionally has a neat trick with the entrance digital camera, as when it is energetic, what appears like a inexperienced LED illuminates subsequent to it – it is truly only a inexperienced dot on the show, however serves the identical goal as LEDs on webcams and so forth.

Show and audio system

  • 5.9-inch AMOLED, 2400 x 1080 decision (446ppi), 120Hz refresh
  • Stereo audio system, 3.5mm headphone port

Having a smaller show will increase the reachability across the machine. That is an instantaneous profit for anybody who struggles with bigger gadgets and also you’re more likely to have the ability to attain all of the areas of this machine that want interplay.

Measuring 5.9-inches on the diagonal, that is smaller than the Xperia 5 II, however do not forget that Sony’s telephones have a 21:9 side ratio, resulting in a taller cellphone. Certainly, Asus’ play right here is to be the extra compact machine. However not too small; it is bigger than the iPhone 12 mini.

The decision and high quality of the show is not affected, nonetheless. It is a Samsung AMOLED panel, filled with vibrancy and completely succesful, with Full HD+ decision cramming within the particulars There’s respectable brightness to chop by means of in brilliant sunshine too.

It is also a 120Hz succesful panel, with choices to have that refresh charge on automated or to power it to 60Hz/90Hz/120Hz. The outcomes are nice total, conserving animations easy.

However it’s a small show and there are compromises that include it. The keyboard is extra compressed which must be thought of. This measurement of machine is not as immersive as bigger shows: for these fascinated with gaming or media consumption which may even be a consideration, as a result of the expertise simply is not pretty much as good.

With media consumption in thoughts, the inclusion of a 3.5mm headphone socket is nice for these nonetheless utilizing wired headphones, that means you do not want a dongle – and with many producers saying that do not have the house, Asus is exhibiting it could possibly occur.

Then we come to the audio system. Many small telephones scrimp on this space, however the stereo providing right here matches with the place of this as a flagship machine – one thing that Sony additionally gives on its Xperia gadgets. The Zenfone 8’s speaker on the bottom does a lot of the heavy lifting in relation to bass, but it surely’s simpler to cowl than front-firing audio system, so you may lose a few of that richness when enjoying video games.

Asus says these audio system are near these provided on the ROG Cellphone 5. Technically that could be true, however they’re a world aside on efficiency attributable to how they’ve been carried out right here. Nonetheless, for those who spend your time watching Instagram Reels in portrait, you may be completely superb.

{Hardware} and efficiency

  • Qualcomm Snapdragon 888 5G
  • As much as 16GB RAM, 256GB storage
  • 4000mAh battery, 30W Hypercharge

Positioned as a flagship machine, it is no shock to search out that the Asus Zenfone 8 has a Qualcomm Snapdragon 888 at its coronary heart. Which means built-in 5G connectivity and energy to match the most effective gadgets of 2021.

There might be a variety of totally different variants of the cellphone – topic to areas – with RAM as much as 16GB and storage as much as 256GB. There isn’t any possibility for microSD card growth, however there are twin SIM slots.

With a flagship {hardware} loadout, it is a flagship expertise you get. Every little thing is refreshingly quick for a compact machine, little totally different to the highest telephones on the market, particularly in day-to-day use.

The Zenfone 8 does undergo for its measurement, nonetheless, in relation to cooling (or, somewhat extra, heating). One of many modifications to pack in all of the performance of this cellphone has been a redesign of the printed circuit boards inside – and cooling appears to have been sacrificed within the course of. We may really feel a substantial warming of the cellphone when enjoying demanding video games, like Name of Obligation Cellular, with the highest half of the cellphone getting uncomfortably heat.

Whereas flagship video games run easily, albeit accompanied by that warmth, we do surprise if critical cell players would select a cellphone like this. Once more, the compact measurement means the expertise simply is not pretty much as good as gadgets with a bigger show and more room for display interplay.

The battery life additionally is not enormous: there’s some limitation that comes from having a 4,000mAh battery and whereas that is nonetheless sufficient to get you thru the day, we have seen higher endurance from these gadgets with greater batteries not too long ago. Evidently having a smaller show right here is not saving an enormous quantity in battery expenditure.

There are energy modes you may deploy, with the flexibility to customize issues to your preferences – maybe turning down the display brightness and refresh charge whereas permitting background information, for instance – however the overriding feeling we get is that the battery life is not pretty much as good as we would count on.

Nonetheless, the 30W charger within the field is welcomed, with that HyperCharge powering the Zenfone 8 again up actually shortly. There isn’t any wi-fi charging, nonetheless.

There’s an under-display fingerprint scanner and we have discovered this to be fairly troublesome. It typically fails to unlock or studies that the sensor is soiled. We have even discovered it struggling to finish the fingerprint registering course of, as a result of it will not progress any additional. We have typically defaulted to unlocking by way of one other technique, so this is not preferrred.


  • Twin rear digital camera system:
    • Fundamental: 64-megapixel, f/1.8 aperture, Sony IMX686 sensor (0.8μm pixel measurement)
    • Extremely-wide: 12MP, f/2.2, Sony IMX363 (1.4μm)
  • Entrance-facing selfie digital camera:
    • 12-megapixel, Sony IMX663 sensor (1.22μm pixel measurement)

Asus has averted gimmicks on the Zenfone 8 and that is noteworthy. Many different producers would have piled in a group of trash cameras with depth sensors and macro sensors so they may put “quad digital camera” on the spec sheet. Not so right here.

As an alternative Asus has gone with a 64-megapixel predominant rear digital camera, utilizing pixel binning to take it from its native 0.8μm pixel measurement to 1.6μm, with 16-megapixel images as normal. You’ll be able to entry the 64-megapixel mode if you wish to, however Asus additionally makes use of this for crop zooming as there is not any optical zoom lens.

When zooming, you may have the choice to leap to 2x (digitally), however past that you need to pinch-zoom throughout the dimensions as much as 8x. You’ll be able to see the optical picture stabilisation working onerous right here, making an attempt to counter your hand actions by the slight delay in what you see on the display. The outcomes are normal digital zoom. Far-off objects find yourself with a reasonably ‘mushy’ outcome – so it could possibly’t compete with trendy optical zoom lenses.

Nonetheless, the principle digital camera is fairly good. It provides pure outcomes, tackling HDR (excessive dynamic vary) scenes pretty effectively, generally over-exposing when issues get a bit of brilliant, however in any other case being completely succesful.

When taking pictures in low gentle, the digital camera will default to an evening mode, taking 4 second exposures and slowly growing the picture on the display. That is nice for nonetheless topics in low-light situations, but it surely’s not as succesful in very darkish situations as you may discover on the Google Pixel, for instance. Taking a photograph of a portray in a dark room and you will get outcome and that is extra prone to meet calls for than turning night time to day open air although.

One of many causes for a higher-resolution sensor is to allow 8K/24fps video, on high of the 4K at 30 or 60fps. Each provide digital stabilisation, with 1080p recording getting HyperSteady for even higher outcomes. Sluggish movement is obtainable as much as 120fps in 4K, with 480fps for 720p video.

The ultra-wide digital camera can also be fairly good. It provides a artistic possibility that is in style, giving that 0.6x view and avoiding an excessive amount of of the blurring in direction of the perimeters that some low cost wide-angle lenses undergo from. It is also fairly constant in color with the common lens, which is pretty uncommon – so good job Asus. It is poor in low-light situations although, so greatest averted at midnight.

The entrance digital camera is a 12-megapixel sensor and we’re glad that Asus has averted the temptation to throw in a higher-resolution sensor for no profit. It is autofocus succesful, which retains issues sharp, and we have discovered the efficiency to be fairly good.

It gives a portrait mode to blue the background utilizing software program smarts, however this tends to blur the background whereas overexposing – and we do not actually just like the outcomes you find yourself with as the sting detection is not the most effective. The very best outcomes are prone to come from not utilizing it, actually. It is also not very adept in low-light situations, not getting the longer night time mode exposures, so low-light selfies are weak.

Total it is a complete digital camera providing and most are prone to discover they’ve just about the whole lot they need from it. The most important omission is the zoom digital camera – and with Sony providing a brand new twin focal size optical telephoto on the Xperia 5 III, it is one thing that Asus clearly misses in comparison with its closest rival.

Software program

The Zenfone 8 comes fairly free from litter and bloatware. You will discover it utilizing Google companies as normal, with Google Uncover accessible from the house web page and Gboard because the default keyboard. That is a fantastic place to begin as there’s little or no to unpick to get going with this cellphone.

Asus does provide its personal Gallery and Climate apps, however that is about it, fairly the change from Asus gadgets only a few years in the past.

However there’s extra weaved into the background. You will discover Recreation Genie – the identical system that the ROG Cellphone 5 makes use of – to spice up your gaming expertise, AudioWizard to tune the sound output to your desire, built-in battery modes which can be customisable, and charging administration to go for slower charging or scheduled charging as acceptable.

Then you definitely’ll discover a vary of choices within the Superior menu to do issues like controlling what the aspect key does, pace up launching of some apps, or to manage the one-handed mode.

The necessity for one-handed mode does elevate some questions, as a result of so much has modified in recent times to assist these utilizing bigger telephones. Navigation, for starters, typically permits the again gesture to return in an app, somewhat than tapping an arrow within the high left-hand nook (which is simply unhealthy app design), whereas that is truly a small handset, so one-handed mode is basically pointless.

Nonetheless, as soon as it is activated, you may swipe down on the very backside of the display and have the whole thing drop down so the highest of the web page is inside attain. We truly discover it extra awkward to carry out that backside swipe than to entry the highest of the show anyway, so it feels a bit misplaced.

However total, there’s little to complain about from the software program expertise. It is a fantastic Android cellphone feeling and it would not appear to have been insensitively messed round with an excessive amount of.


There’s so much to love from the Asus Zenfone 8. It is a good compact cellphone, it has loads of energy, and it gives a fantastic expertise for many who need one thing smaller. It is lighter on the pocket and lighter on the pockets too.

The digital camera is an efficient performer, accepting that there is not any zoom, whereas the audio providing is fairly good, alongside software program that is unfussy and places Google’s Android first.

However the speedy heating beneath load outlines that this cellphone will not work for some folks, like players, whereas the inconsistent fingerprint scanner offers a simple level of irritation.

Which means there is a wholesome stability of professionals and cons – and a few would possibly need to see how Sony’s compact cellphone performs earlier than committing to the Zenfone 8.

Additionally think about

Sony Xperia 5 II

Sony is among the few producers providing a compact flagship cellphone. The 2020 Xperia 5 II is extensively out there and a fantastic performer, packing so much into its physique to maintain you entertained. It is no longer as highly effective because the Zenfone 8 due to older {hardware}, however you would possibly discover it fits your wants higher.
