The iPhone 15 is no longer the “shiny new object” in Apple’s lineup. With the release of the iPhone 17 series and the expansion of Apple Intelligence, many tech buyers are asking: Is the iPhone 15 still worth buying in 2026?

As we navigate the current smartphone landscape, the “value per dollar/Pound” equation has shifted. This review looks at how the iPhone 15 performs today, its long-term viability, and whether you should grab one or look elsewhere.

Quick Verdict: The 2026 Reality Check

The iPhone 15 is a “Smart Buy” in 2026 if you:

• Prioritise reliability and long-term software support over cutting-edge AI features.
• Are you upgrading from an ageing iPhone 11, 12, or a budget Android device?
• Want the USB-C convenience without paying the “Pro” or “New Gen” tax.
• Can find a certified refurbished deal (often priced under £400/$450).

Skip it if you:

• Need Apple Intelligence (The iPhone 15 base model lacks the RAM/NPU for most high-end AI features).
• Demand a 120Hz ProMotion display (the 15 is still stuck at 60Hz).
• Are a power gamer who requires the A19 chip’s thermal management.

Still wants to upgrade. Check our review on the iPhone 16, which could be a newer model and still less pressure on the pocket.

What the iPhone 15 Still Does Well in 2026

1. The Power of the A16 Bionic

Even years later, the A16 Bionic chip remains a workhorse. For 90% of users—browsing, social media, and 4K video playback—the phone feels identical to the newest models. If you aren’t rendering 3D environments, you won’t miss the extra horsepower of newer silicon.

2. A Camera That Defies Its Age

The jump to the 48MP main sensor was the iPhone 15’s saving grace. In 2026, it still captures social-media-ready shots with incredible dynamic range. While it lacks the dedicated telephoto lens of the Pro models, the “2x Optical-quality” crop is perfect for portraiture.

3. Software Longevity

Apple’s support cycle is legendary. Based on current trends, the iPhone 15 will likely receive major iOS updates until at least 2030, with security patches extending even further.

The 2026 Trade-offs: Where It Feels Dated

The “AI Gap”

The biggest differentiator in 2026 is Apple Intelligence. While the iPhone 15 supports the latest iOS, it lacks many on-device AI features (such as advanced Siri and Image Playground) that require the A17 Pro or A19 chips found in newer models.

Charging and Battery Health

The iPhone 15 was the first to adopt USB-C, which is a win, but its 20W charging speed feels sluggish compared to modern standards. Furthermore, if you are buying used, you must check the Cycle Count.

Pro Tip: On iPhone 15 and later, go to Settings > Battery > Battery Health to see the exact cycle count. Look for devices with under 300 cycles for optimal longevity.

Final Verdict: Should You Buy It?

The iPhone 15 is the “sensible” choice of 2026. It isn’t a status symbol anymore; it’s a high-utility tool. If you can find a refurbished model in “Excellent” condition, you’ll get a premium experience for nearly half the price of the current flagship.

However, if you want your phone to be “future-proof” for the AI revolution, we recommend a refurbished iPhone 15 Pro, which offers the RAM needed for Apple’s latest innovations.
