If you’re looking to upgrade an older phone but don’t want to spend over the odds, and you aren’t too fussed about having the latest tech, there’s a good chance you’re weighing up the iPhone 12, 13 or 14. With so many similarities between them, it’s fair to wonder which one is the right choice for you.
In this guide we compare the iPhone 12, 13 and 14 on design, specs, performance and everyday use, all with refurbished pricing in mind, so you can make the smartest choice for your needs.
The short answer
For most people the refurbished iPhone 13 is the best value of the three. It brings a better battery and a faster chip than the 12, yet costs less than the 14, which shares the same A15 chip with only minor extras. On a tight budget the 12 is still a capable 5G phone, and if you want the most years of updates ahead of you, the 14 is worth the stretch.
Why older iPhones are still a great buy
Older doesn’t mean outdated. iPhones are built to last. Apple supports its devices with software updates for around 5 to 6 years, and the hardware rarely feels dated overnight.
That means buying a refurbished iPhone 12, 13 or 14 in 2026 is still a smart move, especially if you’re upgrading from something like an XR, 11 or SE. When you buy refurbished, you also avoid the inflated price of buying new, without giving up the performance you actually use.
iPhone 12 vs 13 vs 14: key specs compared
These three models share a lot of the same specs, though there are a few differences worth knowing before you buy. Here’s a quick side-by-side.
| Feature | iPhone 12 | iPhone 13 | iPhone 14 |
|---|---|---|---|
| Design | Flat-edge, aluminium and glass | Same as 12, slightly heavier | Almost identical to 13 |
| Display | 6.1″ Super Retina XDR OLED | 6.1″ Super Retina XDR OLED | 6.1″ Super Retina XDR OLED |
| Chip | A14 Bionic | A15 Bionic (4-core GPU) | A15 Bionic (5-core GPU) |
| Camera | Dual 12MP (Wide and Ultra Wide) | Same setup with sensor improvements | Slightly better low-light performance |
| Front camera | 12MP, fixed focus | 12MP, fixed focus | 12MP, autofocus |
| Battery life | Up to 17 hours video playback | Up to 19 hours | Up to 20 hours |
| 5G support | Yes | Yes | Yes |
| Original price (RRP) | From £799 | From £779 | From £849 |
So what does that mean in real-world use? The iPhone 12 is still fine for everyday apps, media and multitasking. The iPhone 13 is the sweet spot for battery and performance. The iPhone 14 is much like the 13, with minor camera and safety upgrades.
Performance and everyday use
All three run on Apple’s high-end chips, so for most people the performance difference is hard to notice. Unless you’re playing graphically heavy games or editing video on your phone, each one feels fast and reliable.
The iPhone 12, powered by the A14 chip, is still more than capable in 2026 and beyond. The iPhone 13 steps things up with a stronger GPU and better efficiency, which shows most in battery life. The iPhone 14 uses the same A15 chip as the 13, with one extra GPU core and slightly better thermal management. In day-to-day use they behave much the same: apps open quickly, the camera responds instantly, and multitasking stays smooth.
Camera differences
Apple has steadily improved its cameras year on year, often through software as much as hardware. The iPhone 12’s dual-lens system is still very capable, with sharp daylight photos and decent low-light results. The iPhone 13 builds on this with better sensors, improved night mode and sensor-shift stabilisation. The iPhone 14 adds refinements for low-light shots, plus autofocus on the front camera.
Unless you’re really into photography, the difference won’t feel dramatic. The biggest changes are in night photography and video stabilisation, so if you mostly use your phone for selfies, holiday snaps or Instagram, the 13 or 14 will more than deliver.
Battery life
This is where you’ll notice the biggest jump between generations. The iPhone 12 offers up to 17 hours of video playback, the iPhone 13 stretches that to 19 hours thanks to a bigger battery and more efficient chip, and the iPhone 14 pushes it to around 20 hours. It might not sound like much, but that extra hour or two makes a real difference if you’re on your phone a lot or travelling.

Quick questions
Which is better value, refurbished iPhone 12, 13 or 14?
For most people the refurbished iPhone 13 hits the sweet spot. It offers a meaningfully better battery and chip than the 12, and costs less than the 14, which uses the same A15 chip as the 13 with only minor improvements. If budget is the priority, the 12 is still a capable phone. If you want the most future-proofed option, go for the 14.
Is the iPhone 12 still worth buying in 2026?
Yes, for everyday use. The iPhone 12 supports 5G, has a great screen, and handles day-to-day tasks well. It’s particularly good value as a refurbished device at a budget price point.
What is the difference between the iPhone 13 and iPhone 14?
Less than most people expect. Both use the A15 Bionic chip, though the 14 has one extra GPU core. The main practical differences are the iPhone 14’s improved crash detection, Emergency SOS via satellite, and slightly better battery. For day-to-day use they perform almost identically.
How long will an iPhone 12 be supported with iOS updates?
The iPhone 12 currently runs iOS 18, and Apple typically supports its iPhones for around 5 to 6 years from release. Released in 2020, support is likely to continue through 2026 or 2027, though this isn’t guaranteed. Buying a refurbished iPhone 12 today still gives you a few more years of software updates.
What should I look for when buying a refurbished iPhone 12, 13 or 14?
Check the battery health percentage, aiming for 85% or above for good longevity. Look for a clear graded condition description, whether that’s A, B or C grade. Make sure it comes with a warranty. At The iOutlet, every refurbished iPhone includes a 12-month warranty and goes through a 70-point quality check.
