Refurbished iPhone 17 Summary
The iPhone 17 is one of Apple's newest standard flagship phones, launched in September 2025. It's the right iPhone for you if you want a full iPhone experience (e.g fast performance, a smooth, responsive screen and versatile cameras) without paying Pro prices. You get the A19 chip, a 6.3-inch OLED display with 120Hz ProMotion, a 48MP dual-camera system, USB-C and Apple Intelligence (AI).
If you are comparing iPhone 17 deals, the main difference is testing and aftercare. A professionally refurbished iPhone from The Big Phone Store gives you clear grading, battery checks, warranty cover and support after purchase.

About The iPhone 17
Apple launched the iPhone 17 in September 2025 as the standard model in its latest lineup, alongside the iPhone 17 Pro and Pro Max. The headline change was one that standard iPhone buyers had been waiting years for: the 120Hz ProMotion screen finally came to the non-Pro range. Until the 17, every standard iPhone since 2021 had been stuck at 60Hz, meaning the screen refreshed less frequently, making scrolling and animations feel less smooth. Apple closed that gap here.
Apple also increased the screen size from 6.1 to 6.3 inches and upgraded the Ultra Wide camera to 48MP. Reviews at launch were strong. The Verge described it as "shockingly good value," highlighting the larger display and ProMotion, while Ars Technica called the screen "the real star of the show".
In 2026, the iPhone 17 is one of the strongest all-round iPhones in the refurbished range. It’s newer than most of the models we stock, with years of software support still ahead.
How The iPhone 17 Compares
iPhone 17 vs iPhone 16
The iPhone 17 builds on the iPhone 16 with a faster chip, a bigger high-refresh screen and camera upgrades. Here's how the two differ day to day.
Feature | Technical Upgrade | What You Notice Day to Day |
|---|---|---|
Chip | A19 (up from A18) | Faster apps, games and on-device AI. The phone is better equipped for demanding apps and on-device AI features. |
Display | 6.3-inch OLED, 120Hz ProMotion (from 6.1-inch, 60Hz) | Smoother scrolling and a larger screen make a noticeable everyday difference. |
Front camera | New 18MP Center Stage front camera with autofocus and a square sensor | Selfies and video calls are more flexible, including landscape selfies without turning the phone sideways and automatic framing during some calls. |
Rear camera | 48MP Main and Ultra Wide cameras | The upgraded Ultra Wide camera captures more detailed wide-angle and macro photos, ideal for group photos. |
Battery | Up to 30 hours of video playback; 8 more than the iPhone 16 | This phone should last a full day with moderate use, though gaming and heavy 5G use drain the battery faster. |
Always-On display | Supported via ProMotion | You can glance at time and notifications without waking the phone. |
Build | Ceramic Shield 2 replaces the previous-generation Ceramic Shield front | Up to 3x stronger scratch resistance protects the phone’s appearance long-term. |
-
Size Note: The iPhone 17 is slightly larger than the iPhone 16 due to the 6.3-inch screen. If you’re upgrading from a 6.1-inch phone, you may want to see the difference in person first.
-
The Big Phone Store Team Summary: The iPhone 17 finally brings the 120Hz ProMotion screen to the standard iPhone. It’s a meaningful upgrade over the 16, because you get a faster chip, a bigger display and better cameras, without paying Pro prices. If you can afford it and care about these things, the 17 is a better option.
Our Expert Opinion
The iPhone 17 is the greatest standard iPhone so far. It’s so new that I haven’t even had the chance to see it in person yet, but based on the videos I’ve watched, this phone looks amazing. The screen is the most notable improvement with this model, and it shows. The colours look really nice, and it handles busy games well. More than anything, I get the impression that this is a phone that’s built to last.
It's a good fit if you're upgrading from an iPhone 14 or older and want noticeable improvements in speed, screen smoothness and camera flexibility. Tech enthusiasts and young adults in particular tend to enjoy this phone. If you prefer a smaller phone or want advanced camera tools, this isn't the best option.

Model Highlight
Display
The 120Hz ProMotion display is the iPhone 17's headline feature. For the first time, the standard iPhone gets the high-refresh screen that was once Pro-only. Everything from scrolling to gaming looks smoother and more fluid, and you get an Always-On display too, meaning you can check the time without unlocking your phone. If a smoother screen is what you've always wanted from a standard iPhone, this is the model for you.

From years of working with used phones, we know that problems often start before the phone reaches you. There is a big difference between a second-hand iPhone 17 and a refurbished one, but in both cases it's important to be careful. The main issues are weak battery health, unclear grading, hidden faults, poor replacement parts, blocked phones and sellers listing stock they do not actually have.
Before you buy a refurbished or used iPhone 17, watch out for these common pitfalls.
Risk to Watch Out For | The Issue | What it Means for You |
|---|---|---|
Non-UK or imported models | Some phones may not be intended for the UK market. | You'll pay marginally less upfront, however the phone may sell for as little as 10-20% of its original value later on. Whilst you'll make a small saving to start with, you'll take a huge hit when it's time to dispose of the device, because imported devices are seen as a risk for buyers. |
Phones that are not actually in stock | Some sellers list phones before they physically have them ready to send. | Your phone is your lifeline, and we understand this well. Do you really want to purchase from a company who has a reputation of taking your money and then making you wait for weeks, or in some cases months for your device? |
Weak battery health | A phone can look clean but still have a worn battery. | Many of our competitors don't even mention battery life, and the battery you get is left up to chance. Who wants to spend good money on a device that only turns on for a few hours? Our minimum battery health is 85%, and you can upgrade to 100% at checkout for much cheaper than a high-street battery replacement would cost. |
Hidden faults | Camera, Face ID, sensors or charging port issues may not show in photos. | Many sellers cut costs by not testing your device properly, or in some cases not at all. We believe that every customer deserves a fully functional device from day one, which is why our return rate is one of the lowest in the industry. |
Poor-quality replacement parts | Cheap screens, batteries or camera parts can affect how the phone feels and performs. | Mobile phones are precisely built and sensitive devices. Some sellers use cheap phone parts that are more likely to break or become faulty. We use genuine Apple parts in 95% of the iPhones we repair. On the rare occasion that third-party parts are used, these will be of the highest quality possible, and only for screens and batteries. See our quality charter. |
Blocked, locked or finance-flagged phones | Risky sellers may list phones that later turn out to be blocked, iCloud locked, finance-flagged or not fully reset. | What might seem like a good deal initially could cost you further down the line when the phone is blacklisted from use. We check that your phone hasn't been reported stolen, isn't on the police register, doesn't belong to another company, isn't hacked, and doesn't have any viruses. |
Weak aftercare | Some sellers offer limited support once the phone has been delivered. | If something goes wrong and you need quick support, you may be stuck talking to an AI chatbot. In some cases, the customer support team may live in a different timezone and can't help you when you need it most. Our award-winning team is here to help you by phone, WhatsApp, email and more. |
