iPhone 8 review
At a special event hosted in the Steve Jobs Theater at Apple’s new Spaceship campus in California, Tim Cook took to the stage and announced the iPhone 8 alongside the iPhone X, Apple TV 4K and Apple Watch Series 3.
The iPhone 8 is an incremental update to the hugely popular iPhone 7, offering wireless charging and improved camera tech. Here's our review of the iPhone 8.
iPhone 8: UK pricing and availability
Before we go any further, let’s first address a couple of of the most important factors of any iPhone: when is it going to be released, and how much will it cost?
The iPhone 8, unlike previous iterations of iPhone, is available in only two storage capacities: 64GB and 256GB. It’s also available in fewer colours, but that’s something we’ll come to in more detail below.
For those looking to buy the new iPhone 8 in the UK, it’ll cost you £699 for the 64GB variant, and £849 for the 256GB variant. It’s now on-sale via the Apple Store following a 22 September 2017 launch, and is also available from a number of UK carriers such as EE, Vodafone, O2 and Three.
You can find out more about how to get the best deal in our article about where to buy the iPhone 8. We also have this comparison of how the iPhone X compares to the iPhone 8. (And we've compared it to the Pixel 2 as well.)
iPhone 8: Design and build
In terms of design, the iPhone 8 is what you’d expect from an ‘S’ upgrade. Why? The iPhone 8 sports a similar form factor to the iPhone 7 (and 6s, and 6) but with a handful of changes to make the phone competitive in 2017. So, while it’s slightly thicker than the iPhone 7 at 138.4 x 67.3 x 7.3mm and 10g heavier at 148g, there’s a reason why.
Much of the added bulk can be attributed to the introduction of a glass rear, much like the design of the iPhone 4 and 4s. It provides the smartphone with a much more premium look when compared to aluminium, but potential consumers are worried about how easily it’ll shatter.
Apple claims that the glass is custom-made with a “50 percent deeper strengthening layer”, although we’re not sure what this is compared to as the previous iPhone boasted an aluminium unibody. There’s also the introduction of a steel substructure alongside the 7000 Series aluminium band to provide extra frame reinforcement.
It won’t protect against all drops, but it should hopefully stop it shattering from less significant drops. And those with an iPhone 7 will be happy to know that most, if not all existing cases should fit the iPhone 8 too, ideal for those that worry about dropping the smartphone.
The glass, like the aluminium unibody it replaces, is gently curved at the edges to provide a comfortable, snug fit in the hand. Contrary to what many may believe, the blend of glass and aluminium actually makes the smartphone easier to grip, along with offering a high-end look and wireless charging capabilities.
The iPhone 8 also boasts a ‘cleaner’ look when compared to previous iterations of iPhone, as it has removed much of text from the lower-back of the smartphone. It still says iPhone, Designed in California and Assembled in China (plus the CE marks for European buyers) but markings including the item number are now nowhere to be seen.
There’s also redesigned stereo speakers present on the iPhone 8, boasting a 25 percent boost in volume compared to the iPhone 7, along with deeper bass. It brings it in line with the stereo-equipped iPhone 7 Plus and later, and brings many benefits including a forward-facing speaker for clearer audio when watching videos on your smartphone.
Along with general sound improvements, Apple has been making strides in augmented reality and spatial audio, with the new stereo speakers helping to enhance the AR experience on iOS.
There’s also a difference when it comes to the available colour options. While the iPhone 7 was available in a range of colours, the iPhone 8 is limited to three: Gold, Silver and Space Grey, although the Silver variant boasts a white front and rear with a silver band (which, in our opinion, looks absolutely stunning).
These are different shades than those available in the past though, thanks to the glass rear of the iPhone. It boasts a six-layer ink process that allows for a rich depth of colour present on all models of the iPhone 8, complimented by a colour-matched aluminium band that runs along the sides.
Oh, and the solid-state Home button first introduced on the iPhone 6s is still present on the iPhone 8, unlike with the iPhone X. And those hoping that Apple would revert the decision to remove the headphone jack will be disappointed, as it’s unfortunately not the case.
iPhone 8: Features and spec
What makes the iPhone 8 so impressive? It’s more of an all-round improvement to the smartphone, rather than featuring one killer feature.
Let’s start with the display: it’s still a 4.7in Retina HD display with a sub FHD (1334 x 750) resolution, but now features True Tone technology. First introduced on the iPad Pro 9.7in in 2016, True Tone technology allows your iPhone to detect the ambient light in your settings and adjust the white balance of the display accordingly, to help provide a better and more comfortable viewing experience.
The effect is immediately noticeable when looking at the smartphone, especially when under an off-white light like those in our office. The display picked up on the light levels and made the display warmer and thus, easier on the eyes.
It’s a bit like Nightshift, but much more subtle and reactive based on your environment – only those that purposely look for the change in hue will notice it, but the benefits to eye strain will be universal.
In addition to the True Tone display tech, the iPhone 8 display features a wider colour gamut for better colour reproduction, and dual-domain pixels for wider viewing angles. Of course, it also features the likes of 3D Touch and an oleophobic coating to resist smudges from your grubby mitts.
All this equates to an impressively crisp, detailed and vibrant display, despite the sub-par resolution. While Apple’s sub-FHD display provides better battery life and an improved graphical experience, many similarly-priced Androids boast at least a FHD display, if not something greater.
We’re not asking for a 4K display, but at least bump it up to Full HD so we can enjoy watching Netflix at native 1080p.
Moving beyond the display, the iPhone 8 features the most powerful mobile chipset designed by Apple to date.
It’s called the A11 Bionic chipset, and provides impressive gains in the performance department – but much more than that, too. It should help power high-end AR experiences, and the ‘neural engine’ can help process over 600 billion operations per second.
When translated to real-life usage, the iPhone 8’s A11 Bionic chipset is possibly the most powerful mobile chipset currently available on a smartphone, as is shown in our benchmarks below. It can handle anything, from high-end 3D games to augmented reality experiences rendered in real time, without even the smallest bit of lag.
The A11 Bionic chipset also features a second-generation Apple-designed performance controller that helps to provide great performance when playing games and using power-hungry apps without using too much battery power. It won’t make your iPhone last for days on end, but it lasts a bit longer during intense gaming sessions.
The sheer power of the A11 Bionic baked inside the iPhone 8 is backed up by our benchmark results, which are some of the best we’ve ever seen from any smartphone – especially with regards to the Geekbench 4 score.
We performed several tests, with a higher number indicating a better score for each: Geekbench 4, GFXBench OpenGL, GFXBench Metal and JetStream.
Let’s start with Geekbench 4, which measures the power of the A11 Bionic’s CPU and is a good indicator of the general power of the smartphone. The iPhone 8 scored a whopping 4271 and 10438 in single- and multi-core tests, leaving the likes of the Samsung Galaxy S8 (2017, 6466), Note 8 (2014, 6822) and OnePlus 5 (1955, 6726) in the dust.
It’s the highest scores we’ve seen in any smartphone to date, and is certainly an impressive feat from Apple.
Next, we ran GFXBench OpenGL, the graphical benchmark available for iOS and Android, allowing us to compare performance when gaming with competing flagship devices. We ran two tests in GFXBench OpenGL: T-Rex and Manhattan.
Rather unsurprisingly, Apple’s iPhone 8 got the perfect 60fps score in both, compared to 60- and 55fps from the Galaxy Note 8, 60- and 54fps from the Galaxy S8 and 59- and 55fps from the OnePlus 5.
Some may argue that it’s affected by the sub-FHD display of the iPhone 8, as the likes of the S8 and Note 8 have incredibly high resolution displays to power, and while may be is true, the results remain the same.
We also ran the same tests in GFXBench Metal to compare graphical performance when utilising Apple’s Metal API built into iOS and used by iOS game devs. The scores were much more impressive this time around, as the iPhone 8 scored 119- and 100fps respectively in T-Rex and Manhattan, compared to 60fps across each on 2016’s iPhone 7.
Lastly, we ran JetStream, a benchmark that tests the speed of the mobile browser.
In the case of the iPhone 8, that’s Safari, arguably the best mobile browser on the market. It seems to be backed up by our benchmark results too, as it knocked the iPhone 7 Plus (168.7) off the top spot with an incredibly score of 228. It’s blisteringly fast compared to Google Chrome on the Galaxy S8 (54.9), Note 8 (49.6) and OnePlus 5 (71) too.
For a better understanding of these benchmarks, take a look at the infographic below:
Battery life and wireless charging
Yes, you read that subheading right. The real reason behind Apple’s decision to re-introduce the glass rear on the iPhone 8 is to include support for wireless charging for the first time. After years of fans asking the company to offer wireless charging on the iPhone, Apple has complied, and announced that (in un-Apple fashion) that it’d be compatible with Qi-certified wireless chargers.
That’s right, there’s no proprietary system like with the Apple Watch, meaning it’s compatible with the millions of Qi wireless chargers found around the world, from public places like McDonalds and Starbucks to those that you can buy online for use at home.
With that being said, Apple is due to release its own wireless charging mat dubbed AirPower with advanced wireless charging tech not offered by competitors, but it’s not due out until 2018.
There’s a catch to the wireless charging, though: it’s limited to 5W at the moment. It can be used with more powerful Qi chargers, but it won’t charge the smartphone any faster.
Apple has confirmed that it’s upgrading the iPhone 8 and 8 Plus to ‘fast wireless charging’ via a software update in iOS 11.2, but that bumps it up only to 7.5W. In comparison, some Android smartphones can charge at double that speed, 15W.
The iPhone 8 features a 1,821mAh battery that is actually over 7 percent smaller than the battery found in the iPhone 7, which would leave many to believe that the iPhone 8 is worse off in the battery department.
Somewhat surprisingly, Apple’s second-generation performance controller seems to work very well – the iPhone won’t last days on a single charge, but we’ve found the iPhone 8 to last all day with average use.
And besides, with the addition of wireless charging it’s easier than ever to put your phone in a wireless charging cradle when at work or at home to top up the battery.
iPhone 8: Cameras and photography
The camera has had a bump in spec too, although it’s not ground-breaking. The iPhone 8 features a single rear-facing 12Mp camera that features a larger, faster processor that provides 0 shutter lag and perform better in low-light conditions.
There’s also a new colour filter in the lens, along with ‘deeper pixels’ and Optical Image Stabilisation (OIS) for both photo and video.
What does that mean to you at home? The iPhone 8 takes amazingly detailed photos and performs incredibly well in low-light conditions. Take a look at the following images (click to see original image):
The above photo of St. Pancras hotel is detailed and crisp with great colour reproduction on the surface, but how does it stand up when you zoom in to 100 percent? While the photo loses a bit of the definition that you see when looking at the overall photo, small details like the text on road signs and the individual bricks of the hotel are still readable, although the noise cancellation is much more apparent with an overly ‘soft’ look.
While natural light can help make a photo look better, you should also be wary about it being too bright. The sunny side of St. Pancras is a good example of this – when zooming in, you may notice that the bricks of St. Pancras are almost blown out in places. This may be fixed by using HDR, though, although it’ll depend on the scene.
The iPhone 8’s almost-instant shutter really comes in handy in terms of macro photography. Once you’ve found the perfect focus, the image is captured instantly – no need to worry about your hand moving slightly and losing the focus.
However, like most other smartphones, it’s hard to get the focus just right with macro photography on the iPhone 8. Take a look at the above – the iPhone focused on a handful of leaves instead of the bush as a whole, despite us tapping the bush several times before capturing. So while macro photography is available on the iPhone 8, it might take a few tries before getting the perfect shot.
It’s in the low-light photography department that the improvements in the iPhone 8 camera are most noticeable. Take a look at the above photo in our dedicated low-light area (aka a cupboard) and how well-lit the photo looks. You’re able to make out clearly defined edges, even on Batman’s dark cape, and make out the writing on the water bottle and the pink rubber.
There’s also a surprising lack of noticeable noise cancellation, an unwanted part of much low-light mobile photography. While it won’t capture perfect snaps in pitch black darkness, it should make photos in bars and other dark places much better.
Apple also claims that the iPhone 8 camera has been designed specifically for use with AR. While Apple’s ARKit is compatible with a range of iOS devices, the camera featured on the iPhone 8 (along with the 8 Plus and X) apparently offers superior tracking capabilities, providing high quality AR experiences on iOS.
While it’s hard to put this to the test, we must admit that AR experiences on the iPhone 8 seemed more stable than those on the iPhone 7 Plus, although both devices provide a more-than-satisfactory augmented reality experience for those interested.
Moving beyond photography, there’s also an upgrade in the video department: the iPhone 8 is the first smartphone to be able to record [email protected], an impressive feat. It has also upped the quality of the slo-mo mode, now offering [email protected], up from 120fps on the iPhone 7.
There’s a catch, though. The two new formats are only compatible with the new HEVC codec introduced in iOS 11 as the files are incredibly large (400MB for a minute of [email protected] footage, compared to 170MB for a minute of [email protected]). While this might not sound like an issue to some, the codec isn’t supported by all devices or apps, meaning your friends might not be able to watch your amazingly smooth and detailed [email protected] video.
You can convert to the standard file type when importing videos on Mac, but only those running macOS High Sierra. It’s a bit of a headache if you run into compatibility issues, so we’d recommend sticking to [email protected] unless you really need the high-end 4K recording.
In terms of the front facing camera, it doesn’t seem like anything has changed: the iPhone 8 features the same 7Mp camera with f2.2 aperture as its predecessor, and is more than enough for the likes of Snapchat and FaceTime. Those looking for an upgraded front-facing camera should opt for the iPhone 8 Plus or iPhone X, as both offer front-facing portrait mode capabilities.
iPhone 8: Software
Of course, the iPhone 8 features Apple’s latest iteration of its mobile operating system, iOS 11. iOS 11 brings with it a number of new features, including the Files app and support for Apple’s ARKit, powering high-end augmented reality experiences on a range of compatible iPhones.
In fact, there’s far too much to mention here. If you want to find out more about the software, take a look at the latest iOS 11 news.
The iPhone 8 is a gorgeous, sleek and incredibly powerful smartphone, there’s no doubt about it. The A11 Bionic chipset provided the highest benchmark scores ever, leaving Android rivals in the dirt, and the low-light camera performance is a marked improvement on the iPhone 7.
But no matter how good it is, it just isn’t a tempting enough upgrade for current iPhone 7 owners. If you’ve got an older iOS device or are looking to switch from Android to iOS, the iPhone 8 is a great option, but iPhone 7 owners might not feel it’s worth the upgrade – especially with a raised base price. The addition of wireless charging is handy, but there won’t be a noticeable difference in performance between the 7 and 8 for the majority of tasks.
