Refurbished iPhone 15 Plus Summary


The iPhone 15 Plus gives you the big-screen iPhone experience without paying new-phone money. You get a 6.7-inch OLED display, strong battery life, USB-C charging, Dynamic Island and the high-quality main camera from the iPhone 15 range.

It’s best for buyers who want a large, modern iPhone for watching videos, browsing, taking photos and day-to-day use. The iPhone 15 Plus is one of the best-value large iPhones to buy.

For those comparing used, second-hand and refurbished options, the key risks are condition, battery health, hidden faults and aftercare. A professionally refurbished Apple iPhone 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.

About The iPhone 15 Plus

Apple released the iPhone 15 Plus in September 2023 as the second Plus model after the iPhone 14 Plus. The idea was simple: give people the large 6.7-inch screen and strong battery life of a big iPhone, but without the higher Pro Max price.

The iPhone 15 Plus was also part of a bigger change for Apple. It moved the standard iPhone range from Lightning to USB-C, added Dynamic Island to the non-Pro models, and upgraded the main camera from 12MP to 48MP. That made it feel like a bigger step up than the iPhone 14 Plus.

Sales reports at the time were mixed. The Pro models still took most of the attention, and many buyers continued choosing older iPhones for value. That actually makes the iPhone 15 Plus interesting as a refurbished phone. It is not the flashiest iPhone, but it has the features most people notice: screen size, battery life, camera quality and USB-C.

Our view is that the iPhone 15 Plus is a better choice now than it was at launch. New, it sat close to Pro pricing. Refurbished, it becomes a large-screen iPhone with fewer compromises.

How The iPhone 15 Plus Compares

iPhone 15 Plus vs iPhone 14 Plus

The iPhone 15 Plus is a stronger upgrade over the iPhone 14 Plus than the design first suggests. The biggest changes are the camera, USB-C, Dynamic Island and brighter screen.

Feature

Technical Upgrade

What You Notice Day to Day

Charging port

USB-C replaces Lightning

You can use the same compatible USB-C cable with many other devices, such as newer laptops and power banks. This means you can carry less wires around day-to-day.

Display

6.7-inch Super Retina XDR OLED with up to 2000 nits outdoor brightness

The screen is easier to see outside and better for videos, maps and browsing.

Dynamic Island

Replaces the notch with Apple’s interactive top-screen area

Timers, calls, music, directions and alerts feel easier to follow.

Main camera

48MP main camera instead of 12MP

You can capture memories in more detail, especially in good lighting.

Zoom

2x optical-quality zoom from the 48MP sensor

You can take photos of pets and moderately distant subjects more easily, as well as tighter portrait shots.

Chip

A16 Bionic replaces A15 Bionic

Apps, camera processing and general use feel fast and stable. Ideal for daily use and casual mobile gaming.

Portraits

Improved portrait capture with automatic depth information

You can turn a normal photo into a clean portrait afterwards. This helps when you are taking quick photos of your pets, kids or friends.

Design

Contoured edges and matte colour-infused back glass

It feels slightly softer in the hand than the iPhone 14 Plus and looks more modern.

  • Screen Note: The iPhone 15 Plus still has a 60Hz screen. If you are upgrading from an older Pro iPhone with ProMotion, the display may feel less smooth when scrolling. It also does not support Apple Intelligence. If that matters to you, look at the iPhone 15 Pro or Pro Max.

  • The Big Phone Store Team Summary: The iPhone 15 Plus is still a modern, quality phone for people who want a good size and long battery life without the added price of a Pro model. It’s one of those phones that makes much more sense refurbished than it did at the full launch price.

Our Expert Opinion

The iPhone 15 Plus is a sensible large iPhone, and the screen size and battery life suit most people. From our experience, the iPhone 15 Plus is a strong choice for buyers who use their phone heavily during the day. The battery life is one of its main strengths, and the large screen makes it easier to use maps, watch videos, etc.

If you’re looking to buy a new phone for your parents or older relatives, it’s a strong choice because they may prefer the larger screen.

Whilst the big screen is useful, if you plan on using your phone for intensive tasks such as mobile gaming and complex video editing, the 15 Pro Max may be a better option.

Why it Matters

Screen

6.7-inch Super Retina XDR OLED display with Dynamic Island

You get a large, bright screen that works well for everyday use, including videos, maps, browsing and typing.

Camera

48MP main camera, 12MP ultra wide, 2x optical-quality zoom, 4K video

The main camera is a big step up from older standard iPhones. It is especially useful for everyday photos, people, pets and product shots.

Battery Life

Up to 26 hours video playback, according to Apple

The battery can last all day with moderate use, although 5G and gaming can drain it faster. You can worry less about your phone dying early in the day.

iOS

Launched with iOS 17 and supports current iOS updates

You won’t need to upgrade your device for a few years, because this phone is fully up to date with the latest security and iOS updates in 2026.

Dimensions

160.9mm x 77.8mm x 7.8mm, 201g

It is a large phone. Great for screen space, but also a little heavier because of it.

Every iPhone 15 Plus from The Big Phone Store comes with at least 85% battery health, well above Apple’s 80% replacement threshold. Like New devices have 100% battery health guaranteed.


Popular Models You May Want to Consider

  • Try the iPhone 15 if you want the same core features in a smaller and lighter phone.

  • Try the iPhone 15 Pro Max if you want the large screen on a device with stronger processing capability, a better camera system and Apple Intelligence support.

  • Try the iPhone 14 Plus if you want a large iPhone for less and want to keep using your older Apple charging cables.

  • Try the iPhone 16 Plus if you want a newer large-screen iPhone with Apple Intelligence support.

Model Highlight

Screen and Battery

The iPhone 15 Plus is best for its battery life and screen size. Most people value battery life as one of the most important features of a phone, and with the iPhone 15 Plus you won’t be disappointed. It’s a great, practical choice that makes daily use feel easy.

Its strongest feature is its balance. You get the parts most people use every day, without paying extra for Pro features you may not need.

How We Test the iPhone 15 Plus

The display matters because this is one of the main reasons people buy the Plus model. We check brightness, colour, touch response and screen condition across the full panel.

We use a trusted diagnostics platform called Phonecheck to perform 90+ checks on every device.

Visual and functional tests

  • 85%+ battery health confirmed and charging tested

  • Display brightness, colour and full-screen touch response

  • Face ID — tested, not assumed

  • Front camera and video

  • Speakers, microphone and haptic feedback

  • Wi-Fi, Bluetooth and mobile signal

  • All buttons and sensors

Background and history tests

  • IMEI and network history check via CheckMEND

  • Previous owner’s data fully erased

  • Account locks removed

  • Lost, stolen and blacklist status checked

Only devices that pass every required check are approved for sale. If a device doesn’t meet our standards, it won’t be sold. Each reconditioned X we sell is tested, cleaned and graded in-house before dispatch. 

Common Risks of Buying a Refurbished iPhone 15 Plus

There is a big difference between a second-hand iPhone 15 Plus 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 Plus 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 Plus, 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.
