iPhone 12 Pro Max Specifications 2026: Complete Guide
The iPhone 12 Pro Max stands as Apple’s largest and most advanced smartphone from the iPhone 12 series, featuring a massive 6.7-inch Super Retina XDR display and the powerful A14 Bionic chip.
When I first examined the iPhone 12 Pro Max specifications, three features immediately stood out: the 6.7-inch screen (the largest ever on an iPhone at launch), the advanced triple-camera system with LiDAR scanner, and the impressive battery life that outlasts previous models.
Released in November 2020, this flagship device introduced several groundbreaking technologies including 5G connectivity, ProRAW photography, and Dolby Vision HDR video recording at 60 fps.
In this comprehensive guide, I’ll walk you through every technical specification of the iPhone 12 Pro Max, explaining what each feature means for real-world usage.
Display and Screen Technology (2026)
The iPhone 12 Pro Max display specifications showcase a 6.7-inch Super Retina XDR OLED screen with a resolution of 2778 x 1284 pixels at 458 pixels per inch.
This OLED panel delivers exceptional color accuracy with support for the P3 wide color gamut and True Tone technology that adjusts white balance based on ambient lighting.
The display achieves a typical maximum brightness of 800 nits for standard content, but can reach up to 1200 nits for HDR content playback.
⚠️ Important: The 1200 nits HDR brightness only activates when viewing HDR10 or Dolby Vision content.
The 2,000,000:1 contrast ratio creates incredibly deep blacks and vibrant colors, making it ideal for watching videos or viewing photos.
Apple’s Ceramic Shield front cover provides 4x better drop performance compared to previous iPhone models, though it’s worth noting this refers specifically to drop protection, not scratch resistance.
