The ASUS Zenfone 8 Hands-On Review: A New Compact Directionby Andrei Frumusanu on May 12, 2021 1:30 PM EST

Today ASUS is launching their new mainstream line-up of flagship devices, the Zenfone 8 series. Unlike last year’s iteration of the Zenfone 7 which was defined by the flip-camera design, ASUS is mixing up the formula this year with the new Zenfone 8, a completely different phone in a completely different form-factor, targeting a niche in the market which ASUS sees as an opportunity to differentiate itself in.
The Zenfone 8 is defined by its size: with a 5.9” screen and a width and height of 68.5 and 148mm, it’s by far one of the smallest flagship SoC powered devices in the market. It’s an extreme departure from the Zenfone 7 – however ASUS also introduces the Zenfone 8 Flip, essentially a Snapdragon 888 upgrade over what we’ve seen in the Zenfone 7, though this variant of the Zenfone 8 will be limited in terms of market availability, and today’s article will focus on the smaller Zenfone 8.

The Zenfone 8 and 8 Flip are powered by the new Snapdragon 888. We’ve reviewed the SoC quite extensively over the last few months in a wide range of devices from various vendors – the chip is characterised by increased performance coming at a cost of quite higher power usage due to the shift to a regressed 5nm process node.
ASUS equips the Zenfone 8 from 6 to 16GB of LPDDR5 RAM depending on the SKU model you chose, and comes equipped with 128 or 256GB of UFS 3.1 storage, with no microSD option this time around.
As noted, what really differentiates the Zenfone 8 from its predecessors as well as from other smartphones in the market is its more diminutive stature. At 148 x 68.5 x 8.9mm and only 169g weight, the Zenfone 8 is one of the smallest phones in the market, especially amongst devices powered by the latest flagship hardware internals.
ASUS states that this was a deliberate market positioning that they are experimenting with: the company has seen that while there’s tons of competitors in the now regular “larger” form-factor of phones, there’s actually very little options when it comes to smaller devices. Sony’s Xperia 5 series was one of the rare ones out there with a phone width below 70mm, however many people didn’t like Sony’s extremely elongated aspect ratio, and ASUS pointing out that the Zenfone 8 is now also the only option out there with a device height of below 150mm.
ASUS’s strategy here is I think excellent, and allows them to fill a niche in the market and compete for customers who are looking for such devices. The ergonomics of the Zenfone 8 are generally excellent due to its smaller size, but ASUS also designed the phone to have good in-hand feel due to the curved back glass design as well as the rounded metal frame of the phone.
The build quality of the phone is excellent, and I particularly notice the removal of the plastic “gasket” piece between the phone frame and the display glass that’s usually found on cheaper devices in the market.
The screen itself is a 5.9” OLED with 2400 x 1080 resolution, with an upgraded refresh rate of up to 120Hz, and a touch input of up to 240Hz. Unfortunately there is no variable refresh rate here, neither software nor hardware, so anything above 60Hz comes at the cost of battery life.
The Zenfone 8 uses a “regular” hole-punch front camera module instead of a mechanical flip mechanism of the rear cameras, which is completely fine due to the design limitations of such a much smaller device. I found it a bit weird that ASUS adopted this metallic ring design around the camera – I’ve seen it used before on other devices and I was not fan of it as it really draws the attention to the camera instead of making it inconspicuous. At least here on the Zenfone 8 it’s centred perfectly within the display hole.
The camera setup on the Zenfone 8 is extremely simple: it features the same main camera and ultra-wide module as found on last year’s Zenfone 7 Pro series, meaning a 64MP IMX686 main camera module that bins down to 16MP 1.6µm in regular auto mode pictures and features a f/1.7 optics with OIS, and a 113° UWA module powered by a 12MP IMX363 and f/2.2 aperture with autofocus capabilities. Generally we were not very impressed with this camera setup on the Zenfone 7 last year, and have similar low expectations of the Zenfone 8 – we’ll quickly check out some samples later in the piece.
The bottom of the phone features your typical SIM tray, which this time around does not feature a microSD anymore, USB-C port, as well as a good quality main speaker. Between the USB port and the speaker hole there’s actually also a small LED notification light – something that over the years has seen been deprecated by various vendors in favour on always-on displays. I greatly appreciate this feature as it’s much more power efficient compared to AOD notifications.
At the top of the phone, we find the mythical and elusive 3.5mm headphone jack. Over the many years we see countless vendors drop the feature and trying to promote wireless headphones which cost, more, have worse audio quality, and are prone to degradation due to batteries. Sony and ASUS are two vendors who did drop the headphone jack in the past and reintroduced them in subsequent generations due to negative feedback, so I applaud ASUS for also including it here on the Zenfone 8.
What’s new for ASUS, is the Zenfone 8 is an IP68 rated device, which was one feature limitation of the mechanical flip-camera design of the Zenfone 7, and continues to be so for the Zenfone 8 Flip.
Today’s hand-on review focuses around the Zenfone 8 as that’s what ASUS had sent out as samples, but the company is also launching the Zenfone 8 Flip. This phone is essentially identical to the Zenfone 7 with the exception for the upgrade to a new Snapdragon 888 SoC. Unfortunately, the 8 Flip will see a much more limited release compared to the Zenfone 8, notably with it not launching in the North American market.

shabby - Wednesday, May 12, 2021 - linkIf no sdcard is available then the storage options should be increased, 256gb isn't enough.
The galaxy s10 had a 1tb option and it still had an sdcard.
Boopop - Thursday, May 13, 2021 - linkI've been using a Sony XZ1 Compact for the past three years, without much of an issue. 256gb would be plenty for me, this ASUS phone is appealing. Just because 256gb is not enough for you it doesn't mean it's the case for everyone.
Boopop - Thursday, May 13, 2021 - link(which only has 32GB of storage, without an SD card).
shabby - Thursday, May 13, 2021 - linkSome people just don't use their phones to their full capabilities 🤷🏼♂️
I have 55gb of apps, 30gb of photos and 90gb of videos.
hemedans - Thursday, May 13, 2021 - linki have xz1 compact too, and it does have sd card, where did you get yours without sd card?
nico_mach - Wednesday, May 19, 2021 - linkIf you never install an SD card, then it doesn't have an SD card.
drajitshnew - Thursday, May 13, 2021 - linkI already have have 100+GB. And I don't take 4k videos because of storage anxiety
BedfordTim - Thursday, May 13, 2021 - linkIt is all about the trade offs at the price, but it is certainly a major limitation in terms of what you can do with the phone.
notb - Tuesday, May 25, 2021 - linkGood thesis, bad logic.
A successful product is not a product that SOMEONE will like. It's a product that many people will like.
Asus is pretty good at making niche phones that almost no one buys. So the question is: when (if ever) they start to focus on smartphone business as something they want to have an important role in (as in laptops). For now they're merely notifying their existence.
Linustechtips12#6900xt - Thursday, May 13, 2021 - linkas a galaxy s10e user this looks like a great upgrade, other than the no wireless charging bt otherwise very very compelling for me honestly
