Refurbished Galaxy S24 vs iPhone 15 UK (2026)

If you're deciding between a refurbished Samsung Galaxy S24 vs iPhone 15 in the UK, you're looking at two of the smartest flagship buys on the refurbished market in 2026. Both launched in 2023, both have since dropped to genuinely compelling second-hand prices, and both deliver performance that rivals new phones costing far more. But they suit different kinds of buyers. This guide breaks down every key difference — display, camera, performance, battery, software, and UK price — so you can make the right choice with confidence.

Quick Verdict

The refurbished Samsung Galaxy S24 offers better value per pound, a smoother 120Hz display, a versatile triple camera with optical zoom, and an impressive seven-year software update commitment. The refurbished iPhone 15 wins on video quality, ecosystem integration, and iOS simplicity — and if you're already in the Apple world, it's the more seamless choice. Read on to find out which suits you.

Key Specs at a Glance

Display: S24 Wins on Smoothness

The Galaxy S24 packs a 6.2-inch Dynamic AMOLED 2X panel with a variable refresh rate up to 120Hz and peak brightness of 2,600 nits — one of the best screens in its class. That high refresh rate makes scrolling, gaming, and everyday animations feel noticeably more fluid than on the iPhone 15.

The iPhone 15 uses Apple's 6.1-inch Super Retina XDR OLED — a stunning display with punchy, accurate colours and excellent outdoor legibility, but it tops out at 60Hz. If you've never owned a high-refresh phone before you won't miss it day to day, but side by side the difference is clear. For sheer display quality, the S24 edges ahead; for colour accuracy and natural tone, both phones are excellent.

Performance: A16 Bionic vs Exynos 2400

Apple's A16 Bionic chip inside the iPhone 15 remains one of the fastest mobile processors available in 2026, with exceptional single-core performance and rock-solid iOS optimisation. Every app opens instantly, every animation is smooth, and the chip handles multitasking without breaking a sweat.

The UK version of the Galaxy S24 runs Samsung's Exynos 2400 — a significant step up from earlier Exynos chips and now genuinely competitive in real-world speed. Day-to-day tasks, streaming, social media, and photography feel fast and responsive. Power users and mobile gamers may find the A16 holds a modest advantage under sustained heavy load, but for the vast majority of users, both phones are more than capable in 2026.

Camera: Versatility vs Video Quality

This is where the two phones diverge most clearly, and your priorities will decide the winner.

The Galaxy S24 packs a triple rear camera: a 50MP main sensor, 12MP ultrawide, and a 10MP telephoto lens with 3x optical zoom. That third lens is a real-world advantage — whether you're photographing wildlife, capturing a moment at a gig, or shooting architecture from a distance, you get clean, sharp zoom shots without the blurring that comes from digital cropping. Samsung's Galaxy AI tools also add powerful creative editing features, including the ability to reframe or remove objects from photos.

The iPhone 15 uses a dual camera — a flagship-grade 48MP main sensor (a major upgrade from its predecessor) and a 12MP ultrawide. Without optical zoom, you're relying on a digital crop when you need reach. However, Apple's computational photography and video processing remain best-in-class at this price point: colours are natural, skin tones are flattering, and video quality — especially in Cinematic Mode — is outstanding and well ahead of the S24 for content creators.

• Best for zoom photography: Samsung Galaxy S24
• Best for video and portraits: iPhone 15
• Best for photo editing tools: Samsung Galaxy S24 (Galaxy AI)
• Best for natural colour consistency: iPhone 15

Battery Life and Charging

The Galaxy S24's 4,000 mAh battery comfortably outguns the iPhone 15's 3,349 mAh cell. In real-world mixed use, the S24 typically delivers around 7–8 hours of screen-on time, edging ahead of the iPhone 15's 6–7 hours. If you're a heavy user who pushes their phone hard all day, the S24 is likely to last the distance more reliably.

Charging speeds are modest on both: 25W on the S24 and 20W on the iPhone 15 — both phones fully charge in under 90 minutes. Neither includes a charger in the box (as is standard for both brands), so factor in a USB-C charger if you don't have one. Both support Qi wireless charging when using compatible accessories.

Software Updates and Long-Term Value

Samsung has committed to seven years of Android OS and security updates for the Galaxy S24, carrying it through to approximately 2031. For a refurbished phone purchased today, that's an exceptional guarantee — you won't need to worry about your device becoming unsupported or vulnerable for many years.

Apple doesn't publish formal end-of-life dates, but based on its track record, the iPhone 15 is expected to receive major iOS updates through approximately 2028–2029. Both phones will remain well-supported through 2026 and beyond. If you plan to keep your phone for five or more years, the S24's explicit seven-year commitment is a meaningful advantage.

Build, Design, and Everyday Handling

Both phones use premium glass-and-metal construction with IP68 water and dust resistance — meaning both can survive a drop into one metre of water for up to 30 minutes. Both weigh in similarly: the S24 at 167g, the iPhone 15 at 171g. Both switched to USB-C in 2023, so existing USB-C cables work for either.

The S24 is fractionally slimmer at 7.6mm. The iPhone 15 features Apple's distinctive Dynamic Island — the interactive pill-shaped front camera cutout that displays notifications, live activities, and alerts in a uniquely Apple way. It's a genuinely clever interface element that Android phones haven't replicated.

UK Refurbished Prices in 2026

The refurbished Galaxy S24 is typically £80–£100 cheaper than an equivalent iPhone 15 in the same storage tier — a meaningful saving that could cover accessories, a case, or a quality charger. At refurb-phone.com, both the refurbished Samsung Galaxy S24 and refurbished iPhone 15 are available graded, tested, and backed by a UK warranty, so you can shop with confidence.
