As you'll know, Apple now has a premium iPhone called the iPhone X with Face ID but it is still selling several Touch ID iPhones.
That means if you're in the market for a new iPhone, you have a decision to make. This feature explains how the iPhone 8 and 8 Plus stack up against the iPhone 7 and 7 Plus, as well as the iPhone 6S and 6S Plus. There's also the cheaper iPhone SE, but we've covered that elsewhere.
We've missed the iPhone X off this comparison, but you can see how it compares to the iPhone 8 and 8 Plus in our separate feature if it interests you.

Apple iPhone 8 vs iPhone 7 vs iPhone 6S: Conclusion
The iPhone 8 and 8 Plus naturally win the numbers game compared to the iPhone 7 and 6S models with a faster processor, more storage, an improved display with True Tone technology, extra camera features in the case of the 8 Plus, as well as wireless charging.
The iPhone 7 and 7 Plus are still great options though, especially given their price reductions and the same can even be said for the 6S and 6S Plus if you aren't too bothered about all the latest and greatest features.
With a starting price of £449, the iPhone 6S could be a tempting proposition if your budget doesn't allow for over £500, while the iPhone 7 offers many of the features found on the iPhone 8 bar the processor and wireless charging so is also worth considering if you have a bit of cash to splash but can't quite justify £700.
