Introduction

Apple continues to push the envelope with each iPhone generation, and the iPhone 16 Plus is no exception. But how does it truly compare to last year’s iPhone 15 Plus? Is the upgrade significant, or is it simply incremental?

This comprehensive comparison will break down the major differences between the two models to help you decide if the iPhone 16 Plus is worth your upgrade in 2025.

Design & Display: Subtle Refinements, Same Size

The iPhone 15 Plus already impressed with its sleek aluminum frame and durable Ceramic Shield. The iPhone 16 Plus maintains the same design language but adds slight refinements:

  • Slimmer bezels for a more immersive screen experience.
  • New color options introduced for a fresh visual appeal.
  • Slightly enhanced durability with better scratch and water resistance.

Both models retain the 6.7-inch Super Retina XDR OLED display, ensuring stunning visuals, but the 16 Plus offers higher peak brightness—especially noticeable under direct sunlight.

Performance: The Power of the A18 Chip

One of the standout upgrades is under the hood:

  • iPhone 15 Plus: Powered by the A16 Bionic chip.
  • iPhone 16 Plus: Features the new A18 chip, built on an advanced 3nm process.

This results in:

  • Up to 20% faster CPU performance.
  • Enhanced AI processing capabilities for smarter photography and app management.
  • Improved power efficiency extending battery life by an estimated 1–2 hours compared to the iPhone 15 Plus.

Expert Insight: According to MacRumors, Apple’s A18 chip sets a new benchmark for mobile computing, especially in AI tasks and gaming.

Camera Upgrades: More Than Just Megapixels

Photography enthusiasts will notice the difference:

  • iPhone 15 Plus: Dual-camera setup (48MP main + 12MP ultrawide).
  • iPhone 16 Plus: Introduces a larger sensor and improved Night Mode performance.

New features include:

  • AI-powered photo editing suggestions.
  • Enhanced optical zoom for better detail without distortion.
  • 4K Cinematic Video Mode upgrades for more professional-grade filming.

If smartphone photography matters to you, the 16 Plus offers a noticeable advantage.

Battery Life & Charging: Marginal Yet Meaningful

  • iPhone 15 Plus: Outstanding battery life already, typically lasting a day and a half.
  • iPhone 16 Plus: Pushes further with the new energy-efficient A18 chip and slightly larger battery capacity.

Charging remains consistent:

  • Wired fast charging (up to 50% in 30 minutes).
  • MagSafe wireless charging support.
  • A rumored new MagSafe 2.0 version with faster wireless charging (for iPhone 16 series only).

Software: iOS 18 and Exclusive Features

Both devices run on iOS 18, but the iPhone 16 Plus offers a few exclusive software perks:

  • Smart Display Mode: Your phone intelligently adapts notifications and widgets based on your surroundings.
  • Enhanced Siri 2.0: More intuitive voice control features, available first on the iPhone 16 series.

Expect quicker updates and feature access if you go for the newer model.

Pricing and Value: Is the Upgrade Worth It?

  • iPhone 15 Plus: Likely to see price cuts in 2025, making it a strong value choice.
  • iPhone 16 Plus: Launches at a premium (~$100 more than iPhone 15 Plus at its release).
  • Verdict:
    • ✅ If you’re using an iPhone 13 or older, upgrading to the 16 Plus is a major leap.
    • ✅ If you already have a 15 Plus, it depends—only power users (gamers, photographers) might immediately feel the difference.

Conclusion: Future-Proof or Stick with What Works?

The iPhone 16 Plus is undoubtedly more powerful and smarter, making it a compelling choice for those who crave the latest tech. However, if you’re content with your iPhone 15 Plus and don’t urgently need better AI features or slight battery boosts, holding off another year might be a wise call.
