It was the iPhone that reminded everyone why they fell in love with iPhone in the first place.
Yes, it's been around for a few years now. But it's still covered by Apple's software updates and security patches, still quick and responsive in everyday use, and still looks and feels like a phone worth owning

The iPhone 12 still has the design many people recognise as a modern iPhone, but the safest value comes from how it has been checked. The Big Phone Store has specialised in refurbished, recycled and reused electronics since 1999, helping UK shoppers avoid private-seller risk and unclear device history.
Every refurbished iPhone 12 is tested and graded in-house before dispatch. Testing may use tools such as PhoneCheck and CheckMEND where relevant. Where parts are used, we use OEM-quality parts or higher. We are also a WEEE-certified recycler, helping keep reliable phones in use for longer.

The refurbished iPhone 12 is a great step up from older iPhones because it brings together three useful upgrades: 5G, OLED and MagSafe. The 6.1-inch Super Retina XDR OLED display gives you crisp text, deep contrast and better video viewing than older LCD iPhones. Apple lists the resolution at 2532 x 1170 pixels with 460 ppi.
The A14 Bionic chip keeps everyday use smooth across messages, banking apps, streaming, web browsing, maps, camera use and light gaming. The iPhone 12 also supports 5G, Wi-Fi 6 and Bluetooth 5.0, giving you modern connection options at a lower refurbished price.
The dual 12MP camera system gives you wide and ultra-wide shots, Night mode, Deep Fusion, Smart HDR 3 and 4K Dolby Vision HDR video recording. It is a solid choice for holidays, family photos, pets, social posts and everyday video.
A refurbished iPhone 12 is not the same as a typical second hand iPhone 12. A private seller may offer a low price, but you may not know the battery health, repair history, network status or whether the phone has been properly wiped.
Professionally Refurbished | Typical Used Phone |
Tested across 90+ points | Usually not fully tested |
Minimum 85% battery health | Battery may be weak or unknown |
Data-wiped before sale | Data removal depends on the seller |
12-month warranty included | Often no warranty |
Clear condition grading | Condition can be vague |
Network/history checks completed, including CheckMEND where relevant | Risk depends on seller honesty |
Yes. A refurbished iPhone 12 is usually safer than buying used privately because it has been tested, graded, data-wiped and sold with warranty cover. You also reduce the risk of blocked devices, weak batteries, hidden repair issues and difficult returns.
Every refurbished iPhone 12 we sell is fully functional. The grade describes cosmetic condition, not performance.
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 12 performance.
Good shows more visible wear and is best if you want the lowest price on a fully working iPhone.
"People forget that the iPhone 12 was actually a landmark release — 5G, OLED across the entire lineup for the first time, and that flat-edge redesign that Apple has stuck with ever since. It wasn't just a good phone, it was a genuinely influential one.” - The Big Phone Store Technical Team
Every refurbished iPhone 12 comes with at least 85% battery health as standard. That supports normal daily use across calls, messages, maps, browsing, social apps, streaming, photos and video.
Like New phones include 100% guaranteed battery health. Consider this option if you use maps often, stream on the go, rely on your phone for work, take lots of photos or simply want the strongest battery option from day one.
You will get at least 85% battery health as standard. If you choose a Like New refurbished iPhone 12, you get 100% guaranteed battery health.
A cheap iPhone 12 should still feel clean, quick and ready for daily use. A lower price usually reflects cosmetic grade, storage size or a current offer, not reduced functionality.
Each device is checked before dispatch across key areas, including:
Battery health and Lightning charging
MagSafe and wireless charging response
Display brightness, colour and touch response
Face ID
Wide and ultra-wide cameras
Speakers, microphones and haptics
Wi-Fi, Bluetooth and mobile signal
Buttons, sensors and other checks
OLED screen review: We check brightness, touch response and visible screen marks because the OLED display is one of the best upgrades from older iPhones.
MagSafe response: We test magnetic charging behaviour and wireless charging response, as MagSafe is a key iPhone 12 feature.
Network and history checks: We complete network and history checks, including CheckMEND where relevant.

I bought two iPhones for me and my partner. One was good, and the other was very good. They both arrived in great condition! The new batteries work perfectly. I'm really happy with both covers and can’t beat the prices. Excellent service, quick delivery, definitely would buy again!
