Phone arrived very quickly. Absolutely perfect. Only thing I had to do was change its location from USA to UK but that was no issue, it was just in device settings (just meant all my auto fill options were USA choices for phone number etc, just factory settings, easy fix) phone is perfect, as described. I actually can’t believe it was so pristine. I always ended up getting a new contract phone when I wanted an upgrade but my partner suggested Backmarket to try. I was very hesitant going for a refurbished phone as it’s not what I’m used to. But not only is the phone perfect, just like brand new, I was able to trade in my previous IPhone 14 Pro. I was given an offer, and expected it to pay out a good bit less as it seemed to too good to be true. But no, got the offer accepted and it just meant technically the price of my phone was incredible. It was very easy to trade in. And I love my new phone.

The device was in perfect condition, with no scratches or issues. The battery health was at 100% and the phone was almost brand new, it even came with the box as if I had gotten it from the Apple Store. They were also very quick to dispatch and the parcel arrived days early.

I've always just ordered direct from Apple in the past. Then I discover I can get a brand new Iphone 17 (box had been opened and phone switched on a few weeks ago, but it's unmarked, nothing configured and battery showing 100% health), with the same length warranty that Apple themselves would provide, for £112 less than getting direct from Apple. Why wouldn't you? I wish I'd discovered this option years ago.

It’s in fantastic condition, you can’t tell that it’s refurbished at all. Delivery was really quick - it arrived the day after I ordered it. This is my second time using backmarket and I highly recommend them

is this the 3rd time buying apple products from back market and, as always, im a happy customer. The phone arrived quickly, nicely protected, inside its original box. Zero battery cycles, 100% battery health and not a single sign of usage. i bought this in march 2026 and the phone noted that it had been first turned on in January of the same year. i really bought a new phone for the price of a refurbished!

Arrived in super quick time and was a new device rather than a refurbished one for the same quoted price. Very happy with the service and the phone itself as I needed it to use with new hearing aids. Still getting used to the loss of the button but really please with the improved camera. Should have upgraded years ago!

Who is this for?

The iPhone 17 suits students, commuters and professionals who want smooth scrolling and responsive performance for browsing, apps and gaming, plus reliable photo and video quality for social media or work. Its 6.3-inch screen and 120Hz ProMotion make it a comfortable upgrade over older 6.1-inch non‑ProMotion models, while still remaining pocket‑friendly. If you prioritise long‑zoom photography, consider a Pro model with a dedicated telephoto, but for most users the iPhone 17’s dual 48MP system covers everyday shooting well.

Pros & Cons: Pros Cons 120Hz ProMotion OLED delivers smooth visuals and a responsive UI. No dedicated telephoto lens for optical zoom. A19 chip provides strong all‑round performance. USB‑C data limited to USB 2 speeds. 48MP + 48MP rear cameras and 18MP Centre Stage front camera for versatile shooting. eSIM‑only design may not suit all travellers or mobile networks. Wi‑Fi 7, Bluetooth 6, UWB for modern connectivity and accessories. Larger than older 6.1-inch models; not the most compact iPhone. IP68 rating and Ceramic Shield 2 front add durability. No expandable storage (typical for iPhones).
