iPhone 8 vs iPhone 7 comparison review

In September and October of 2017 Apple launched its new batch of smartphones, including the iPhone X (which got most of the headlines) and the iPhone 8 (which for many people is actually the better option). The tech community has a short memory, but do these new products really put 2016"s iPhone 7 in the shade? Has it become a bad phone overnight? Not so fast.

In this article we put the new iPhone 8 up against the iPhone 7 in a head-to-head comparison, weighing up the two devices" design, features, specs and prices, to help you decide which is the right phone for you.

If we convince you one way or the other, note that you can buy the iPhone 7 here and buy the iPhone 8 here. And we"ve got a separate iPhone buying guide and roundup of the best iPhone deals.

iPhone 8 vs iPhone 7: At a glance

We"ve broken down the main specs and features of the iPhone 8 and iPhone 7 in the table below, but you can continue reading for a more in-depth comparison of the specs and features to find out which is best for you.

While the iPhone X is a fairly radical redesign, broadly speaking the iPhone 8 has the same chassis design as the iPhone 7 - and the iPhone 6s and 6 before it. It"s a three-year-old design: a classic, but one that"s starting to show its age.

However, a few tweaks have been added over the years, and this year"s tweak may be the most significant: the iPhone 8 features a glass front and back, which means it"s compatible with wireless charging accessories. It also gives the smartphone a more "premium" look compared to aluminium... although there have been some worries about its durability. (We haven"t noticed any more scratches than normal, but your mileage may vary.)

iPhone 8 vs iPhone 7: Design

Apple claims the glass is custom-made with a "50 percent deeper strengthening layer", and points to the introduction of a steel substructure alongside the 7000 Series aluminium band to provide extra frame reinforcement. But subjectively it seems undeniable that the new handsets are at least a little less robust than their predecessors, and we would recommend the use of a case.

Other than issues with breakage, this change also means the iPhone 8 is fractionally bigger than the iPhone 7 at 138.4mm x 67.3mm x 7.3mm (compared to 138.3mm x 67.1mm x 7.1mm) and 10g heavier at 148g.

Neither the iPhone 7 nor the 8 have a headphone port; and they both have customisable solid-state Home buttons that buzz to simulate a click, rather than actually clicking downwards, and should in theory be less likely to malfunction than older-style Home buttons.

It"s certainly true that we"ve not had any problems with the new buttons. But it should be added that the epidemic of faulty Home buttons that we saw around the iPhone 5 era had largely been solved before the non-clicking buttons came along.

Colour finishes

If you"re looking for colour options the iPhone 7 is the better choice. That phone comes in five colours: silver, gold, Rose Gold, black and Jet Black. (It used to come in Product Red, too, but that"s since been discontinued.)

The iPhone 8 is only available in (a seemingly slightly pinker) gold, silver and Space Grey.


The iPhone 8 doesn"t get Face ID, but it does get one major new flagship feature.

Wireless charging

As mentioned above, the iPhone 8 (and all other 2017-vintage iPhones) have glass-back designs and because of this are able to be compatible with wireless charging accessories.

At launch the iPhone 8"s wireless charging capabilities were capped at 5W, which meant it was no faster than the wired charger that was bundled with it (and in practice we found it very slightly slower, presumably because of inefficiencies with the third-party wireless charging pad we were using). However, the iOS 11.2 update will raise the cap to a faster 7.5W and give us all a speed boost - assuming we use compatible accessories.

The iPhone 8 uses Qi, so any accessories certified with this standard should work with it.

Tech specs

There are some important changes on the inside, with the iPhone 8 gaining a faster processor chip, a True Tone display, improved 4K and slo-mo video support, more advanced Bluetooth and twice the storage.

  • iPhone 7: 7Mp, f/2.2, Retina Flash, 1080p video


Apple hasn"t released tech specs of the iPhone 8"s battery unit, but the 7 and 8 have the same claimed battery lives: up to 14 hours talk time, up to 12 hours of internet use and up to 40 hours of wireless audio playback. Our subjective tests support this. The iPhone 8 won"t last days on a single charge, but we"ve found it to last all day with average use.

Unlike the 7, the iPhone 8 offers compatibility with Qi-standard wireless chargers, as well as fast charging: Apple says it can charge up to 50 percent in 30 minutes.

UK price

Unsurprisingly the iPhone 7 - which is still on sale following the launch of the 8, alongside the 6s - is a cheaper option than the 8. Here are the prices:
  • iPhone 8 (64GB): £699

  • iPhone 8 (256GB): £849

  • iPhone 7 (32GB): £549

  • iPhone 7 (128GB): £649
