You’re looking at two phones on Remobile. The refurbished iPhone 15 starts at €431. The refurbished iPhone 16 starts at €612. That’s a gap of roughly €150–180 depending on your storage. The question every smart buyer asks is simple: what exactly does that extra money buy?
This guide answers that for every model pair — standard vs. standard, Pro vs. Pro, and Pro Max vs. Pro Max — through the one lens that actually matters here: refurbished value. Not retail. Not specs-sheet fantasy. What you get at Remobile today, with a 40-point inspection, brand-new battery option, and 24-month warranty on both devices.
Pick the refurbished iPhone 15 if: you want a flagship 48MP camera and USB-C at the lowest possible price, don’t need Apple Intelligence, and plan to upgrade again in 2–3 years.
Pick the refurbished iPhone 16 if: you want Apple Intelligence, 4K/120fps video, Camera Control, and faster 25W MagSafe charging — or if the 256GB tier closes the gap to just €73.
Chip Performance: A16 Bionic vs. A18
Refurbished iPhone 15 and iPhone 16 — both 40-point certified at Remobile.eu
The iPhone 15 runs the A16 Bionic — the same chip that powered the iPhone 14 Pro. It’s Apple’s 4nm processor with a 6-core CPU, 5-core GPU, and 16-core Neural Engine. In 2026, it handles every mainstream app, game, and workflow without strain.
The iPhone 16 moves to the A18 — Apple’s second-generation 3nm chip. According to independent benchmark testing at NotebookCheck, the A18 delivers roughly 15–20% faster single-core performance and meaningfully better GPU throughput. The bigger story is the Neural Engine: the A18’s expanded on-device AI capacity is the hardware requirement for Apple Intelligence — and the A16 simply doesn’t meet it.
Round verdict: a practical tie for 2026 daily use. The A18 earns its price only if you need Apple Intelligence or plan to keep the phone past 2029.
Camera Upgrades: What Actually Changed
Both phones share a 48MP main camera and a 12MP Ultra Wide. On paper, identical. In practice, three things are meaningfully different.
Ultra Wide aperture and macro
The iPhone 16 opens its Ultra Wide to f/2.2 (from f/2.4 on the 15) and gains macro photography — previously a Pro-only feature. If you shoot close-up food, products, or nature, this is a real gain.
Camera Control button
The iPhone 16 adds a dedicated physical button on the right side — a capacitive control for launching the camera, adjusting zoom, and shooting without touching the screen. In practice it changes how naturally you shoot, especially one-handed.
4K/120fps video
The iPhone 15 records up to 4K at 60fps. The 16 doubles that to 4K at 120fps — full-resolution slow motion. The 16 also introduces Audio Mix: machine learning that separates voice, background, and ambient sound in real time for studio-quality audio without an external mic.
Round verdict: for stills in good light, the iPhone 15 camera is excellent. For video and macro photography, the iPhone 16 is a genuine step forward.
Battery Life and Charging Speed
Apple rates the iPhone 15 at up to 20 hours of video playback. The iPhone 16 extends that to 22 hours. The bigger gap is charging: the 16 supports 25W MagSafe (up from 15W on the 15) — roughly 30% faster to a full charge.
Here’s what changes the refurbished calculation: Remobile ships every device with a certified battery, upgradeable to brand-new at checkout. The worn-cell problem that plagues private secondhand sales simply doesn’t exist here.
Round verdict: iPhone 16 wins on numbers, but less dramatically than it sounds when both start with a fresh battery from Remobile.
Apple Intelligence: The Feature That Splits This Decision
Apple Intelligence is exclusive to A17 Pro and A18 chips — the standard iPhone 15 is not eligible.
This is the feature that makes the 15 vs. 16 comparison fundamentally different from any previous iPhone generation gap. Apple Intelligence requires the A17 Pro chip or newer. The standard iPhone 15, running on A16, does not qualify — regardless of which iOS version it runs.
What Apple Intelligence gives you on the iPhone 16:
- Writing Tools — rewrite, proofread, and summarise text across any app
- Priority Notifications — AI surfaces what actually needs your attention
- Smart Reply in Mail and Messages
- Image Playground and Genmoji — on-device AI image generation
- Enhanced Siri — cross-app actions, on-screen context, ChatGPT integration
- Page and email summaries at a tap
If these features are central to how you work, the iPhone 15 is off the table. If you find Apple Intelligence more novelty than necessity, the iPhone 15 does everything else at a meaningfully lower price.
Software Support Runway
Apple supports iPhones for six to seven years. The iPhone 15 should receive full iOS updates until approximately 2029. The iPhone 16 extends that to 2030–2031. See Apple’s official comparison for model-level details. For 4+ year ownership, the iPhone 16 gives you meaningfully more runway.

Pro vs. Pro: Refurbished iPhone 15 Pro vs. iPhone 16 Pro
The Pro comparison is where the price gap gets larger — and where the upgrade story becomes considerably more compelling. At Remobile, the refurbished iPhone 15 Pro starts from €596 (128GB). The refurbished iPhone 16 Pro starts from €769 (256GB).
| Criterion | Refurbished iPhone 15 Pro | Refurbished iPhone 16 Pro |
|---|---|---|
| Remobile price (from) | €596 (128GB) | €769 (256GB) |
| Chip | A17 Pro | A18 Pro |
| Display size | 6.1 inches | 6.3 inches |

The Pro jump is genuinely more compelling. The Ultra Wide leaps from 12MP to a full 48MP — a completely different capability for landscape, architecture, and product photography. You also get a larger 6.3” screen and 4 extra hours of battery.
Important note: unlike the standard iPhone 15, the iPhone 15 Pro supports Apple Intelligence via its A17 Pro chip. If Apple Intelligence is your main reason to consider the 16 series, the refurbished 15 Pro at €596 is a legitimate and cheaper alternative to the 16 Pro at €769.
Round verdict: for Pro buyers, the 16 Pro’s 48MP Ultra Wide and bigger display tip the balance. For anyone who just wants Apple Intelligence at the lowest Pro price, the refurbished 15 Pro is the smarter buy.
Pro Max vs. Pro Max: Refurbished iPhone 15 Pro Max vs. iPhone 16 Pro Max
At Remobile, the refurbished iPhone 15 Pro Max starts from €604 (256GB). The refurbished iPhone 16 Pro Max starts from €865 (256GB) — a gap of €261. Here’s exactly what that extra money buys.
| Criterion | Refurbished iPhone 15 Pro Max | Refurbished iPhone 16 Pro Max |
|---|---|---|
| Remobile price (from) | €604 (256GB) | €865 (256GB) |
| Chip | A17 Pro | A18 Pro |
| Display size | 6.7 inches | 6.9 inches |
| Main camera | 48MP f/1.8 | 48MP f/1.8 |
| Ultra Wide camera | 12MP f/2.2 | 48MP — major upgrade |
| Telephoto (optical zoom) | 12MP, 5x periscope | 12MP, 5x periscope |
| Max video | 4K / 60fps ProRes | 4K / 120fps ProRes |
| Camera Control | No | Yes |

| Battery (video) | Up to 29 hours | Up to 33 hours |
| Battery capacity | 4,422 mAh | 4,685 mAh |
| MagSafe charging | 15W | 25W |
| Frame | Titanium | Titanium |
| Remobile warranty | 24 months + 60-day returns | 24 months + 60-day returns |
The Pro Max gap is the largest in this comparison — €261 more for the 16 Pro Max. The gains are real: a bigger 6.9” screen, the Ultra Wide jumps from 12MP to 48MP, 4K/120fps video, and 4 extra hours of battery life. Apple Intelligence is supported on both (both carry the A17 Pro and A18 Pro respectively).
The honest verdict: if you’re a heavy video creator or professional photographer who will genuinely use 4K/120fps ProRes and the 48MP Ultra Wide daily, the 16 Pro Max justifies €261 more. For everyone else — including most people who just want the biggest iPhone screen and the longest battery — the refurbished iPhone 15 Pro Max at €604 is exceptional value.
Round verdict: 16 Pro Max wins on specs. 15 Pro Max wins on value. Your call depends on how hard you push the camera.
Verdict: Is the Upgrade Worth It?
For most buyers: the refurbished iPhone 15 at €431 is the smarter purchase. It delivers a genuine flagship camera, USB-C, Dynamic Island, and at least three more years of iOS updates. The €181 you save on 128GB buys a quality case, AirPods, or simply stays in your pocket. At 256GB the gap collapses to €73 — at that point, the iPhone 16 wins easily.
Choose the refurbished iPhone 16 if:
- You want Apple Intelligence and plan to actually use writing tools, Smart Reply, or enhanced Siri
- You shoot video beyond casual clips — 4K/120fps is a real, usable upgrade
- Camera Control and Audio Mix fit your daily shooting habits
- You’re planning to keep the phone for 4+ years and want the longer chip runway
- You need 256GB — at €73 more, the 16 is the obvious choice
In the Pro and Pro Max comparisons, the verdict shifts. The 16 Pro and 16 Pro Max gain a 48MP Ultra Wide (up from 12MP), larger displays, and 4+ extra hours of battery. If you’re in the Pro tier and planning to keep the phone for 3+ years, the 16 Pro earns its premium more convincingly. For Pro Max buyers on a budget, the 15 Pro Max at €604 offers outstanding value — same 5x periscope telephoto, Apple Intelligence support, and 29 hours of battery for €261 less.
Either way, both phones arrive at Remobile with the same promise: 40-point inspection, brand-new battery option, 24-month warranty, 60-day no-questions returns, and free shipping. Yesterday’s flagship, today’s smartest buy.
