Refurbished iPhone 11 vs iPhone 12 UK: Which to Buy?

If you're weighing up a refurbished iPhone 11 vs iPhone 12 UK, you're in good company — both are among the most searched budget iPhones in Britain right now. They look similar on paper, but step inside and the iPhone 12 brings a string of meaningful upgrades: an OLED screen, Apple's faster A14 Bionic chip, 5G connectivity, and a better camera system. That said, the iPhone 11 still holds its own as one of the best-value smartphones you can buy. Here's everything you need to know to choose the right one.

Design and Build Quality

The most noticeable visual difference is the edge design. The iPhone 11 uses softly rounded aluminium edges — familiar and comfortable, but starting to look dated. The iPhone 12 switched to flat surgical-grade aluminium, echoing the more premium aesthetic of the iPad Pro and every iPhone since. It also introduced Ceramic Shield front glass, which Apple claims is four times tougher against drops.

• iPhone 11: Rounded aluminium frame, standard glass front
• iPhone 12: Flat aluminium frame, Ceramic Shield front — significantly more drop-resistant

Both phones share the same 6.1-inch footprint, so they feel similar in the hand. The iPhone 12 is slightly thinner and lighter, making it more pocketable day to day.

Display: The Biggest Upgrade from iPhone 11 to 12

This is where the refurbished iPhone 12 pulls clearly ahead. The jump from LCD to OLED is significant — deeper blacks, richer colours, and a sharper image that you'll notice every single day.

The iPhone 12's OLED panel makes scrolling through social media, watching video on Netflix, or simply reading feel noticeably more vivid. The 460 ppi resolution is also a significant step up — text looks crisper and images more detailed. If screen quality matters to you, this is the iPhone 12's strongest argument for the extra cost.

Performance: A13 vs A14 Bionic

Both chips are more than capable for everyday use in 2026, but there are real differences worth knowing:

• iPhone 11 (A13 Bionic): Launched in 2019. Handles browsing, messaging, social media, and gaming without breaking a sweat. Still genuinely fast and smooth.
• iPhone 12 (A14 Bionic): Launched in 2020 — Apple's first 5-nanometre chip, around 20% faster in CPU benchmarks. More future-proof for the years ahead.

For most users, neither phone will ever feel slow. But if you plan to use the phone for three or more years — as many refurbished buyers do — the iPhone 12 gives you more headroom before apps outgrow the hardware.

Camera Comparison

Both phones feature a dual 12MP rear camera setup, but the iPhone 12 brings meaningful, real-world improvements.

Rear Camera

• iPhone 11: 12MP main (f/1.8 aperture) + 12MP ultra-wide; Night Mode on main lens only; Smart HDR
• iPhone 12: 12MP main (f/1.6 aperture — lets in more light) + 12MP ultra-wide; Night Mode on all cameras including ultra-wide; Smart HDR 3; Dolby Vision HDR video recording

Front Camera

• iPhone 11: 12MP TrueDepth — great for selfies in good light
• iPhone 12: 12MP TrueDepth with Night Mode — a genuine improvement for dim environments and evening shots

For casual everyday photography, the iPhone 11 takes excellent shots. But if you photograph in low light regularly — restaurants, concerts, evenings out — the iPhone 12's Night Mode across all cameras makes a real, visible difference. The Dolby Vision HDR video recording is also a standout feature for anyone who shoots video content.

5G vs 4G LTE: Does It Matter in the UK?

The iPhone 12 was Apple's first 5G model. Whether this makes a practical difference for you depends on your situation:

• Major UK cities (London, Manchester, Birmingham, Bristol, Leeds): 5G is now widely available — you'll benefit from faster downloads, smoother streaming, and quicker load times.
• Rural or suburban areas: 4G still dominates coverage in many parts of the UK, so the iPhone 11's lack of 5G is less of a practical disadvantage.
• Future-proofing: 5G networks continue to expand rapidly across the UK. A 5G phone in 2026 makes increasing sense if you plan to keep the device for three or more years.

For many buyers, 5G alone justifies choosing the iPhone 12 over the iPhone 11 — especially when the price gap is often under £40 at refurb-phone.com.

Battery Life

Despite the iPhone 11 packing a physically larger battery (3,110 mAh vs 2,815 mAh on the iPhone 12), Apple rates both at 17 hours of video playback. In real-world use, the iPhone 11 can edge slightly ahead in screen-on time, but the difference is marginal for typical daily usage patterns.

When buying refurbished, battery health is the key variable. Every iPhone at refurb-phone.com is battery-tested and clearly graded, so you always know the health of the cell before you buy — no nasty surprises after a few weeks.

Refurbished Prices UK (2026)

The typical price gap between a refurbished iPhone 11 and iPhone 12 in the UK is around £30–£50. Given everything you gain with the 12 — OLED display, 5G, improved camera, and a faster chip — that is a compelling premium for most buyers.

iOS Support and Software Longevity

Apple's software support lifecycle is one of the best reasons to choose iPhone when buying refurbished. Both models currently run iOS 18, but their futures differ:

• iPhone 11 (launched 2019): Now entering the final phase of Apple's support cycle. Expected to receive one or two more major iOS updates before being dropped.
• iPhone 12 (launched 2020): At least another year or two of full iOS updates, plus extended security patches beyond that — giving you more peace of mind.

For security and continued access to new app features, the iPhone 12 gives you meaningfully more runway before the phone becomes obsolete from a software perspective.
