About the Apple iPhone 12

The Apple iPhone 12 marked a turning point for the standard iPhone line in October 2020, bringing an OLED display, 5G connectivity, and a flat-edged redesign to the non-Pro model for the first time. In 2026, it remains a functional budget option, though it sits in an increasingly tight spot. The A14 Bionic chip still runs iOS 26 and copes well with browsing, social media, messaging, and streaming. The dual 12MP camera takes respectable photos in good light, and Night Mode brings usable results after dark. 5G support gives it a meaningful edge over the iPhone 11, and the OLED display is a clear step up from any LCD-equipped iPhone. However, five-plus years on, the limitations are harder to ignore: the 60Hz display feels sluggish next to modern phones, the Lightning port is a growing inconvenience, Apple Intelligence is not supported, and battery health on used units will have degraded. At refurbished prices around 150 pounds, the iPhone 12 still offers solid value as a no-frills daily driver for light users or a reliable backup phone, but buyers should have realistic expectations about its remaining useful life.

Frequently Asked Questions

Is the Apple iPhone 12 still worth buying in 2026?
For light users on a tight budget, the iPhone 12 remains a functional daily driver with 5G, an OLED display, and iOS 26 support. However, it is approaching the end of its software update lifecycle, lacks Apple Intelligence, and used units will likely have degraded batteries. It is best suited as an affordable entry point into the Apple ecosystem or a reliable backup phone rather than a long-term primary device.
How long will the Apple iPhone 12 receive software updates?
The iPhone 12 currently runs iOS 26 and is expected to receive major updates through approximately 2027, with security patches likely continuing beyond that. Apple typically provides around seven years of major iOS releases from launch. Buyers should expect one to two more years of full feature updates.
Does the Apple iPhone 12 have 5G?
Yes. The iPhone 12 supports sub-6GHz 5G, which provides faster download and upload speeds compared to 4G LTE on supported networks. This was one of the biggest upgrades over the iPhone 11, which only supported 4G. Smart Data Mode automatically switches between 5G and LTE to help conserve battery.
How good is the Apple iPhone 12 camera in 2026?
The dual 12MP camera with Wide and Ultra Wide lenses takes good photos in daylight and reasonable results in low light with Night Mode. It records 4K Dolby Vision HDR video, which was impressive at launch and still produces quality footage. It lacks the telephoto lens and LiDAR scanner of the Pro models, and newer iPhones have significantly better computational photography, but for social media and everyday snapshots it remains perfectly adequate.
Does the Apple iPhone 12 support Apple Intelligence?
No. Apple Intelligence requires an A17 Pro chip or newer, and the iPhone 12's A14 Bionic does not meet this requirement. This means no access to AI writing tools, smart notification summaries, Genmoji, Image Playground, or the enhanced Siri features introduced with Apple Intelligence.
What is the difference between the Apple iPhone 12 and iPhone 12 Pro?
The iPhone 12 Pro adds a telephoto camera for optical zoom, a LiDAR scanner for faster autofocus and AR, a stainless steel frame instead of aluminium, Dolby Vision recording at 60fps instead of 30fps, and additional RAM. The standard iPhone 12 offers the same A14 chip, OLED display, and 5G connectivity at a lower price, making it the better value if you do not need the extra camera capabilities.
Is the Apple iPhone 12 Pro worth it over the iPhone 12?
The biggest upgrade is the camera system. The 12 Pro adds a telephoto lens for optical zoom, a LiDAR scanner for faster autofocus in low light, and a premium stainless steel frame instead of aluminium. You also get brighter peak display brightness at 800 nits HBM versus 625 nits. The 12 Pro starts at around £215 SIM-free compared to £165 for the standard model, so you are paying roughly £50 more. If photography matters to you, the Pro is a worthwhile step up. Compare iPhone 12 Pro deals. Compare Apple iPhone 12 Pro deals →
