Let us start with something most articles on this subject will not tell you: the Samsung Galaxy S27 Ultra has not been announced. The iPhone 18 Pro was launched on 9 September 2026 with full specifications and prices. Samsung's next Ultra is, at this point, an expectation.

So this comparison does two honest things. First, it lays out exactly what the iPhone 18 Pro is. Second, it explains how to choose between the iPhone and Samsung's Ultra line in Nigeria — the criteria that will still apply when the S27 Ultra exists.

What is confirmed: the iPhone 18 Pro

  • 6.3-inch Super Retina XDR OLED, 120Hz, with a smaller Dynamic Island showing up to three Live Activities
  • A20 Pro chip on a 2nm process: 6-core CPU, 7-core GPU up to 40% faster than the A19 Pro, Dual 16-core Neural Engine with roughly double the AI processing, 50% more memory bandwidth
  • New vapour chamber with three times more surface area, for up to 40% better sustained performance
  • 48MP Fusion Main camera with variable aperture — six laser-cut blades, four settings from ƒ/1.48 to ƒ/4
  • Pro controls with manual aperture, shutter speed, white balance and a histogram
  • Apple Reference Image — signed sensor data that proves a photo was not edited
  • Up to 36 hours video playback (eSIM-only models); 50% charge in about 15 minutes
  • C2 modem, N1 chip with Wi-Fi 7 and Bluetooth 6, USB-C, 5G
  • iOS 27 with Apple Intelligence and Siri AI in beta
  • $1,199 in the US, £1,199 in the UK, roughly ₦2.5 million from Nigerian sellers

What is not confirmed: the Galaxy S27 Ultra

No launch date, no chip, no camera specification, no price. Judging by how Samsung's Ultra line has developed, buyers usually expect a large 6.8-inch-plus panel, a high-end Snapdragon or Exynos chip, a long-reach periscope zoom, S Pen support and Galaxy AI features. Treat all of that as expectation. We will publish a real comparison when Samsung publishes real specifications.

How to choose between iPhone Pro and Galaxy Ultra in Nigeria

The decision is rarely about benchmarks. In practice it comes down to six things.

1. Resale value. iPhones resell faster and stronger in Nigeria. If you change phones every 18 months, that gap is real money.

2. Repairs. Both are expensive to fix here. Android flagship screens are usually cheaper to replace than Pro-series iPhone screens, and independent repairers are more comfortable with them. See screen replacement costs.

3. Zoom versus aperture. Samsung's Ultra line has traditionally led on long optical zoom — useful at events and in stadiums. Apple's new answer is aperture control and provable image authenticity. Different tools; decide which you actually use.

4. Software life. Both companies now support flagships for many years. Apple's track record on delivering updates to older hardware remains the benchmark.

5. The ecosystem you already own. If your laptop, watch, earbuds and family group are all Apple, switching costs you convenience. If your household runs on Android, the reverse is true.

6. eSIM. US iPhone 18 Pro units are eSIM-only with no SIM tray. Most Galaxy units sold here keep a tray. Read our SIM guide.

The Nigerian price reality

Price note: naira figures are estimates dated 10 September 2026 from Nigerian sellers, not official prices.

At about ₦2.5 million for the iPhone 18 Pro, and Samsung's Ultra line historically arriving at a similar level, both are simply out of reach for most buyers. That is not a criticism of either phone — it is arithmetic.

Which is why the more useful comparison for most people is not iPhone versus Samsung, but flagship versus what you can actually afford:

Our verdict, honestly stated

If you want the best camera you can buy today and you are committed to spending flagship money, the iPhone 18 Pro is confirmed, available and genuinely a step forward — the variable aperture is not a marketing feature.

If you want a Galaxy Ultra, wait for it to be announced rather than paying a premium on the current model days before a successor appears. And if you were only ever comparing the two because you enjoy the argument, spend ₦400,000 on a phone from our range and put the rest to work.
