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.

Close to perfection. The body may have tiny micro-scratches. For items with screens, the screen will be flawless.

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

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!

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!

I bought the premium option. I have used it for about 2 weeks so far and it works as expected, had no physical flaws, and normal battery health. Really pleased with the product so far.

Item appears brand new and big saving from buying from Apple. Really pleased with the purchase. Trade in for my old iPhone was close to what Apple were offering. Paid £655 for a brand new iPhone 17 RRP £799. Highly recommend.

The iPhone 17 is Apple’s standard model for 2025 that brings Pro‑level touches to the mainstream, including a larger 6.3-inch OLED display with ProMotion 120Hz, a new A19 chip, and upgraded cameras. It comes with iOS 26 and Apple Intelligence features out of the box, making it a practical choice for everyday use and content creation.

Key features:

Release year: 2025.
Display: 6.3-inch Super Retina XDR OLED with ProMotion up to 120Hz, Always‑On, and Dynamic Island.

Rear cameras: 48MP Fusion Main + 48MP Fusion Ultra Wide; advanced features such as Night mode, Smart HDR, and Cinematic video.
Front camera: 18MP Centre Stage camera with autofocus and 4K video.
Connectivity: 5G (sub‑6 GHz and mmWave), Wi‑Fi 7, Bluetooth 6, second‑gen Ultra Wideband, and Apple’s N1 wireless chip.

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).
