## Product: Apple iPhone 17 Pro Max (512 GB) - Deep Blue [6.9-inch Display with Promotion, A19 Pro Chip, Best Battery Life in Any iPhone Ever, Pro Fusion Camera System, Center Stage Front Camera]
**Brand:** Apple

The iPhone 17 Pro Max measures **163.0 x 77.6 x 8.8mm** and weighs **233 grams**, featuring Apple's new heat-forged aluminum unibody design.

## Dimensions

| Spec | Measurement |
|------|-------------|
| Height | 163.0 mm (6.42") |
| Width | 77.6 mm (3.06") |
| Depth | 8.8 mm (0.35") |
| Weight | 233g (8.22 oz) |

## Design Changes

Apple switched from titanium to aluminum for improved thermal performance. The aluminum unibody integrates with the vapor chamber cooling system to deliver:
- **40% better heat dissipation**
- **40% longer sustained performance**
- Consistent temperatures during intensive tasks

## Comparison

**vs iPhone 16 Pro Max:** Slightly thicker (8.8mm vs 8.25mm) and heavier (233g vs 227g), but improved weight distribution makes it feel more balanced.

**vs Galaxy S25 Ultra:** Similar screen size, but Samsung is lighter (218g) and thinner (8.2mm).

## Case Compatibility

**⚠️ iPhone 16 Pro Max cases will NOT fit.** You need [iPhone 17 Pro Max specific cases](https://www.amazon.com/s?k=iphone+17+pro+max+case&tag=shopsavvy00-20) due to:
- Thicker body profile
- Larger camera plateau
- Revised button placement

## Comfort

Despite the large 6.9-inch display, the curved aluminum edges and matte finish make extended use comfortable. The refined weight distribution reduces fatigue compared to previous generations.
