If you use Apple Intelligence features (Writing Tools, Photo Cleanup, enhanced Siri), yes. If not, iPhone 15 remains excellent and the upgrade is less compelling. The Camera Control button and Action Button are nice additions. For iPhone 14 or older users, iPhone 16 is a clear upgrade.
Camera Control is a new physical button on the right side of iPhone 16 models. It acts as a dedicated camera shutter (one click to take a photo, hold for video), and supports swipe gestures to adjust zoom, exposure, and other camera settings. It also enables quick launch of the camera from standby.
No — Apple Intelligence requires the A17 Pro chip or newer (iPhone 15 Pro) or the A18 chip (iPhone 16 lineup). The standard iPhone 15 uses the A16 Bionic, which is not compatible with Apple Intelligence. Only iPhone 15 Pro and iPhone 15 Pro Max support Apple Intelligence.
iPhone 16 and iPhone 16 Plus use the A18 chip (3nm, TSMC). This is the same generation as the Pro lineup (A18 Pro), with slightly fewer GPU cores. The A18 is approximately 30% faster in CPU and 40% faster in GPU performance vs the A16 Bionic in iPhone 15.
Expert Analysis: iPhone 16 vs iPhone 15
iPhone 15 vs iPhone 16 is Apple's consecutive generation comparison — the 2023 lineup vs the 2024 lineup, relevant for buyers deciding whether to upgrade and for the used iPhone market in 2026 where iPhone 15 models are available at significant discounts.
iPhone 15 (September 2023): Apple's 2023 lineup brought USB-C to iPhone for the first time (replacing Lightning), the Dynamic Island (extending from iPhone 14 Pro to standard iPhone 15), and a 48MP main camera. iPhone 15 base ($699): A16 Bionic (same chip as iPhone 14 Pro), 6.1" Super Retina XDR display (60Hz, no ProMotion), USB-C (USB 2.0 speeds), Dynamic Island, 48MP Main + 12MP Ultra Wide. iPhone 15 Plus ($799): same specs in 6.7". iPhone 15 Pro ($999): A17 Pro chip (3nm, first), titanium design (lighter than steel), Action Button (customizable side button replacing mute switch), 48MP Main + 12MP Ultra Wide + 12MP 3× Telephoto, USB 3 speeds via USB-C, ProMotion 120Hz OLED. iPhone 15 Pro Max ($1,199): same with 5× tetraprism periscope telephoto lens. iPhone 15's A16 Bionic (base/Plus) delivers excellent real-world performance for all tasks. iPhone 15 strength: USB-C finally enables faster charging with standard cables and direct connection to laptops, external drives, and cameras.
iPhone 16 (September 2024): iPhone 16 base ($799): A18 chip (3nm, significantly faster than A16 in CPU and GPU), 6.1" display, Camera Control button (new dedicated hardware camera button with swipe controls), 48MP Main + 12MP Ultra Wide, Action Button now standard on all models. iPhone 16 Plus ($899): same in 6.7". iPhone 16 Pro ($999): A18 Pro, 6.3" screen (larger than 15 Pro's 6.1"), 48MP Main + 48MP Ultra Wide + 12MP 5× Tetraprism Telephoto (periscope now on base Pro), Camera Control, ProMotion 120Hz. iPhone 16 Pro Max ($1,199): 6.9" screen (largest iPhone ever). iPhone 16 features: (1) Apple Intelligence — on-device AI requiring iPhone 16 or M1+ iPad/Mac; Writing Tools, Genmoji, Image Playground, Priority Messages, and Siri upgrade all require A18/A18 Pro Neural Engine. (2) Camera Control — hardware button on right edge; tap to launch camera, slide to zoom, long-press for video. (3) Video: 4K/120fps Dolby Vision recording on iPhone 16 Pro (first on any phone). iPhone 16 improvements over 15: +30% CPU, +40% GPU (A18 vs A16), Apple Intelligence access, Camera Control, better video.

Upgrade decision 2026: iPhone 15 Pro/Max owners who got A17 Pro should not upgrade — their chip is essentially equal to A18 for real-world tasks, and both run full Apple Intelligence. iPhone 15 base/Plus owners have the A16, which does NOT run Apple Intelligence — if AI features matter, iPhone 16 is the upgrade path. For new buyers: iPhone 15 (now available refurbished from Apple $499–$549 or used $350–$450) is excellent value if Apple Intelligence isn't needed; iPhone 16 ($799 or refurbished from $649) adds Camera Control and Apple Intelligence.
