About the Apple iPhone 15

The Apple iPhone 15 remains a smart buy for anyone who wants a modern iPhone experience without chasing the latest model. It brought several features that were previously exclusive to the Pro line, most notably the Dynamic Island, which replaced the notch for a more interactive and visually appealing notification system. The 48MP main camera was a major leap from the 12MP sensor on the iPhone 14, delivering sharper photos with a 2x telephoto crop mode for closer shots. Under the hood, the A16 Bionic chip handles everyday tasks, gaming, and multitasking with ease, though it does not support Apple Intelligence features that require the newer A17 Pro or A18 chips. The switch to USB-C marked the end of Lightning, bringing universal charging compatibility and simpler cable management. With a 6.1-inch Super Retina XDR OLED display hitting 2,000 nits peak brightness and reliable all-day battery life, the iPhone 15 delivers a refined, capable experience. Now available at reduced prices since the iPhone 16 launch, it offers outstanding value for buyers who prioritise proven performance over cutting-edge AI features.

Frequently Asked Questions

Is the Apple iPhone 15 still worth buying?

Yes, the iPhone 15 remains an excellent phone in 2025 and beyond. It offers a 48MP camera, Dynamic Island, USB-C, and the capable A16 Bionic chip at a lower price than when it launched. The main trade-off is the lack of Apple Intelligence support, which requires newer chips. For users who value camera quality, build, and everyday performance over AI features, it is a strong choice.

Does the Apple iPhone 15 support Apple Intelligence?

No, the iPhone 15 does not support Apple Intelligence. These AI features require the A17 Pro chip found in the iPhone 15 Pro and Pro Max, or the A18 chips in the iPhone 16 range. The iPhone 15's A16 Bionic chip handles all other tasks well but cannot run the on-device AI models that Apple Intelligence requires.

How good is the Apple iPhone 15 camera?

The 48MP main camera is a significant upgrade over the iPhone 14's 12MP sensor, capturing sharper and more detailed photos. It includes a 2x telephoto crop mode for closer shots, a 12MP Ultra Wide lens, and improved computational photography with Smart HDR 5. Portrait mode automatically detects people and pets without needing to switch modes manually.

Does the Apple iPhone 15 have USB-C?

Yes, the iPhone 15 was the first standard iPhone to feature USB-C, replacing the Lightning connector used since 2012. This means you can use the same cable to charge your iPhone, iPad, Mac, and many other devices. It supports USB 2 data transfer speeds and fast charging with a compatible adapter.

How long will the Apple iPhone 15 receive software updates?

Apple typically supports iPhones with software updates for five to six years after launch. The iPhone 15, released in September 2023, can be expected to receive iOS updates through at least 2028 or 2029, ensuring ongoing security patches, new features, and app compatibility for years to come.

What is the Apple iPhone 15 battery life like?

The iPhone 15 delivers up to 20 hours of video playback, which provides reliable all-day battery life for most users. It supports fast charging via USB-C, reaching around 50% in 30 minutes with a 20W or higher adapter, and MagSafe wireless charging at up to 15W.

Is the Apple iPhone 15 Plus worth it over the Apple iPhone 15?

The biggest reason to choose the iPhone 15 Plus is battery life. Its larger 4,383mAh cell delivers up to 26 hours of video playback compared to 20 hours on the standard iPhone 15, making it one of the longest-lasting iPhones ever. You also get a 6.7-inch display instead of 6.1 inches. Both share the same A16 Bionic chip and 48MP camera, so the Plus is purely about screen size and endurance. Compare iPhone 15 Plus deals.

Is the Apple iPhone 15 Pro worth it over the Apple iPhone 15?

The iPhone 15 Pro's biggest advantage is Apple Intelligence support, which the standard iPhone 15 cannot run. You also get a 120Hz ProMotion display, a 3x telephoto lens, the faster A17 Pro chip, titanium construction at just 187g, and USB 3 data speeds. The iPhone 15 Pro starts at £469.99 SIM-free versus £379.99 for the iPhone 15. If AI features and a smoother display matter to you, the Pro is well worth the step up. Compare iPhone 15 Pro deals.
