Looking for a premium iPhone experience at a lower price? This page covers everything you need to know about buying a refurbished iPhone 15 Pro Max, including its features, grading options, warranty, and expert advice. Whether you're upgrading or buying your first iPhone, discover why a refurbished model can be a smart, reliable choice.
The iPhone 15 Pro Max is best for buyers who want Apple’s biggest screen, strongest battery life in the 15 range, and most flexible camera system without paying new-release prices. Its main upgrades over the iPhone 14 Pro Max are the lighter titanium design, USB-C charging, A17 Pro chip, Action Button and 5x optical zoom camera.
For buyers comparing used, second-hand and refurbished options, the key risk is condition, battery health, hidden faults and aftercare. A professionally refurbished iPhone 15 Pro Max at The Big Phone Store costs significantly less than new, and gives you the same premium Apple experience with clearer grading, testing, warranty and returns support.
The iPhone 15 Pro Max was announced at Apple’s “Wonderlust” event on 12 September 2023 as the most advanced iPhone of that year. While the standard iPhone 15 brought Pro-style features to the regular model, the Pro Max was about pushing Apple’s top-end phone further: a lightweight titanium frame, more power, and a much longer zoom camera.
The biggest story was the new titanium frame. Apple moved away from the heavier stainless steel design used on earlier Pro Max models, and tech reviewers such as The Guardian’s Samuel Gibbs praised the change because it made Apple’s largest iPhone noticeably lighter. The A17 Pro chip added to the “Pro” positioning, with Apple leaning more heavily into high-end gaming and creator workflows.
But the launch also had a small accessory controversy. Apple introduced FineWoven cases as its new leather alternative for the iPhone 15 series, but the material was quickly criticised for marking easily. Even though this had nothing to do with the device itself, it became one of the main early talking points surrounding the iPhone 15 family.
Even so, the iPhone 15 Pro Max became one of the most widely praised premium iPhones of its generation, and iPhone 15 models are still some of the most in-demand devices in the second-hand market as of early 2026.
The iPhone 15 Pro Max is not a complete rethink of the iPhone 14 Pro Max, but it improves the areas premium iPhone buyers care about most: weight, zoom, charging, speed and controls.
Feature | Technical Upgrade | What You Notice Day To Day |
Design | Titanium frame replaces stainless steel | It feels lighter in the hand despite keeping the same large screen size. |
Charging | Lightning replaced with USB-C | You can use the same cable with many other devices, such as newer laptops and power banks. There’s no need to carry a specific charger just for your iPhone anymore. |
Camera zoom | New 5x telephoto camera, up from 3x on iPhone 14 Pro Max | Better close-up shots from further away, especially for concerts, travel, and wildlife photography. |
Chip | A17 Pro replaces A16 Bionic | Faster performance, better gaming support and better long-term support for future iOS features. |
Apple Intelligence | Supported on iPhone 15 Pro Max with compatible iOS versions | You can use Apple’s newer AI features, including writing tools, smarter photo features and more. This makes the 15 Pro Max feel more current than the 14 Pro Max. |
Action Button | Replaces the mute switch | You can set it to open the camera, torch, Focus mode, or another feature you use often to personalise your experience. |
Weight | 221g, down from 240g on iPhone 14 Pro Max | It is still a large phone, but feels less heavy during long use. Easier for gaming sessions and photography. |
Video | ProRes, Log video and USB-C workflow support | Higher video quality. Better for creators who plan to edit their videos later or transfer large video files to a computer. |
Connectivity | Wi-Fi 6E support, up from Wi-Fi 6 on iPhone 14 Pro Max | You may notice faster downloads and more stable Wi-Fi, especially in busy homes or offices. |
Important note
The iPhone 15 Pro Max supports faster USB 3 data transfer, but you need a compatible USB 3 cable for this. The cable included in the box is mainly for charging and does not give you the fastest transfer speeds. If you transfer large files often, you may want to use a different cable.
Big Phone Store team summary
Compared with the iPhone 14 Pro Max, the iPhone 15 Pro Max is lighter, faster and better for zoom photography. The biggest everyday changes are the convenient USB-C port, the 5x zoom camera, the customisable Action Button and the lighter titanium feel.
The iPhone 15 Pro Max is our #3 best-selling model out of 29 iPhones for the past five months.
*The iPhone 15 family has seen a significant rise in popularity in early 2026.
“The refurbished iPhone 15 Pro Max is a phone I’d confidently recommend to someone who wants a premium iPhone but doesn’t want to pay the retail price for this year’s newest model. Most customers looking at this model want one of three things: the biggest screen, the best camera in the iPhone 15 range, or a phone that will feel modern for the next few years. The 15 Pro Max covers all three.
My best friend actually has the 15 Pro Max, and I’m still jealous of the camera quality. We used it to record some YouTube videos, and the colours looked really crisp.”
Charlie Ingram, TBPS
I’d recommend the iPhone 15 Pro Max for photographers, content creators, mobile gamers, business users, and anyone who wants the biggest iPhone screen without moving to the iPhone 16 Pro Max.
It’s also a strong choice for buyers upgrading from an iPhone 11 Pro Max, 12 Pro Max or 13 Pro Max. You will notice the camera zoom, display brightness, battery life, USB-C charging and faster performance straight away.
Avoid the 15 Pro Max if you want a smaller phone, lower price or lighter pocket feel. It’s still a large device, even though it weighs less than previous Pro Max models. The price is only really justified if you’ll make use of its more advanced features. If you won’t, the regular iPhone 15 may be more suitable.
If you already own an iPhone 14 Pro Max, the upgrade is useful but not essential unless you really want USB-C, 5x zoom, the Action Button or the lighter build.
Find the iPhone 15 Pro Max across our grades, colours and storage options.
Conditions: Like New, Pristine, Very Good, Good
Colours: Natural Titanium, Blue Titanium, White Titanium, Black Titanium
Storage: 256GB, 512GB, 1TB
Every grade (condition) we sell is fully functional. The grade describes cosmetic condition only, and refurbished devices undergo 90+ automated checks to confirm that they are fully functional before sale.
Like New is the cleanest cosmetic option and includes 100% guaranteed battery health. Choose it if you want the best condition available.
Pristine has very light signs of use and suits buyers who want a cleaner-looking phone for less.
Very Good may show light marks, but still gives you full iPhone 15 Pro Max performance.
Good shows more visible wear and is best if you want the lowest price on a fully working modern iPhone.
On the iPhone 15 Pro Max, cosmetic wear is most noticeable on the frame edges, camera surround and screen border. If you use a case and screen protector, Good or Very Good can make a lot of sense because the performance, camera system and software experience work exactly the same.
For UK buyers, every refurbished iPhone 15 Pro Max we sell is SIM-free and unlocked for compatible UK networks, so you can use your current SIM or choose a new plan.
Feature | Technical Details | Why It Matters |
Screen | 6.7-inch Super Retina XDR OLED display, 2796 × 1290 resolution at 460 ppi, ProMotion up to 120Hz | Large and sharp display for streaming, gaming, editing photos and everyday use. |
Camera | 48MP Main, 12MP Ultra Wide, 12MP 5x Telephoto, 12MP TrueDepth front camera | Gives you Apple’s best iPhone camera system from the 15 range, with much better zoom than the standard models. |
Battery life | Up to 29 hours of video playback; TBPS devices have minimum 85% battery health | Lasts the whole day and is well suited to heavy use. Best battery life in the iPhone 15 range. |
iOS | Supports current iOS updates and modern Pro iPhone features | You won’t need to upgrade your device for a few years. Gives you long-term app compatibility, security updates and access to newer Apple features. |
Dimensions | 159.9 mm × 76.7 mm × 8.25 mm, 221 g | Big screen and strong battery, but lighter in the hand than previous models. |
Every iPhone 15 Pro Max from The Big Phone Store comes with at least 85% battery health, with upgrade options available. This is the highest minimum battery health of any refurbished seller. Like New devices have 100% battery health guaranteed.
Note: The average iPhone battery lasts around 1000 cycles before significant degradation occurs.
If you’re looking for a reliable but less expensive device, try the iPhone 15.
If you want a large phone but aren’t interested in more expensive advanced features, try the iPhone 15 Plus.
Try the iPhone 15 Pro if you want a smaller device with many of the same pro features.
If you have a higher budget and would prefer longer support and even more advanced camera features, consider the iPhone 16 Pro Max.
The best feature on the iPhone 15 Pro Max is the 5x telephoto camera. It is the biggest reason to choose this model over the regular iPhone 15, iPhone 15 Plus or even the smaller iPhone 15 Pro.
Most phone cameras are fine when your subject is close, but at a distance things can start to get blurry. The 15 Pro Max camera is better for capturing these distant details. That matters at concerts, school plays, sports events, holidays, wildlife spots and family days out, where you usually cannot move closer and need the zoom to do more of the work.
The 5x zoom also gives the phone a longer useful life for people who care about photos and video. You are not only getting a larger screen and strong battery life, you are getting the most capable camera system in the iPhone 15 range, which is why the Pro Max is still a smart refurbished choice in 2026.
The iPhone 15 Pro Max is a premium camera phone, so we pay close attention to the parts customers rely on most: the 5x telephoto camera, 48MP main camera, screen, battery, and USB-C charging port.
Our testing does not stop at opening the camera app. We check photo and video performance, autofocus, lens switching, image clarity and front camera function. We also test charging behaviour through the USB-C port, because a worn or damaged port can affect daily use quickly.
Our internal refurbishment process for the iPhone 15 Pro Max includes device checks across 90+ points, including:
85%+ battery health confirmed and USB-C charging tested
Display brightness, colour and full-screen touch response
Face ID tested, not assumed
Front camera, rear cameras and video performance
Speakers, microphone and haptic feedback
Wi-Fi, Bluetooth and mobile signal
Buttons, sensors and MagSafe response
IMEI and network history checks using trusted industry tools
Full data wipe
We do not sell every iPhone 15 Pro Max we receive. Any device that fails our checks is not sold as a working iPhone 15 Pro Max.
There is a big difference between a second-hand iPhone 15 Pro Max and a refurbished one, but in both cases it's important to be careful. From years of working with used phones, we know a cheap iPhone 15 Pro Max can come with risks that are not obvious from photos. 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.
Don't just look at the cost. When buying a used iPhone 15 Pro Max, watch out for these common pitfalls.
Risk to watch for | What it means | 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 zoom, focus, Face ID, sensors or USB-C port issues may not be obvious from 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 | Low-quality 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 are here to help you by phone, WhatsApp, email and more. |
