After 28 days of rigorous testing—from London’s bustling streets to the Scottish Highlands—we’ve uncovered the true differences between Apple’s 2024 flagships. Forget spec sheets; here’s how these phones actually perform in daily life. Find out if the iPhone 16 plus is worth the extra money compared to the iPhone 16.
Design & Display: More Than Just Size
iPhone 16
- Frame: Aerospace aluminium (same as MacBook Pro) with Ceramic Shield 2024
- Display: 6.1″ Super Retina XDR (461 PPI)
- Our test: Flawless for Instagram scrolling, but side-by-side with the Plus, Netflix shows reveal slightly deeper blacks on the larger display.
- Weight: 170g (“Fits perfectly in joggers” – Our fitness tester)
iPhone 16 Plus
- Display: 6.7″ Super Retina XDR (460 PPI)
- Game-changer: In Brighton sunlight, the 2000-nit peak brightness made Google Maps readable without squinting.
- Weight: 199g (“Feels premium but demands two-handed typing” – Our UX team)
- Pro Tip: The Plus’s 0.2mm thicker design hides a secret—better heat dissipation during 4K recording (confirmed via FLIR thermal imaging).
External Insight: While the iPhone 16 offers a compact feel perfect for everyday tasks, the iPhone 16 Plus is designed with media consumption in mind, giving a more immersive experience for video streaming and mobile gaming. Apple iPhone 16 specs.

Camera: Identical Hardware, Different Experiences
Shared Specs:

Key Differences:

- Stabilization: The 16’s lighter body showed more micro-jitters in handheld 4K footage (see our YouTube side-by-side).
Pro Insight: “For TikTok creators, the 16’s portability wins. For filmmakers, the Plus’s endurance is king.” – James Abbott, Pro Videographer
External Insight: While the camera systems are virtually identical, the larger size of the iPhone 16 Plus may lead to smoother stabilization in video footage, especially in challenging shooting conditions. This is important for creators who shoot on the go. Apple iPhone 16 Camera Features.
