iPhone 17 Pro Max vs iPhone 18 Pro Max: Upgrades Compared
The iPhone 17 Pro Max vs iPhone 18 Pro Max comparison is no longer a guessing game. Both phones are now announced, and Apple has published full specifications for each. This guide, updated in September 2026 using those figures, shows exactly what changed from one generation to the next, what stayed the same, and who gains the most from upgrading.
Key Takeaways
- The iPhone 18 Pro Max moves from the A19 Pro to the A20 Pro chip, with a 7-core GPU in place of 6 cores.
- Its 48MP Fusion Main camera gains a variable aperture (ƒ/1.48 to ƒ/4.0); the ultra wide, 4x telephoto and 8x optical-quality zoom are unchanged.
- Apple rates video playback at up to 45 hours on the iPhone 18 Pro Max, against up to 39 hours on the iPhone 17 Pro Max.
- Display, depth (8.75 mm), USB 3, 25W MagSafe and Qi2 charging, and storage up to 2TB are the same on both. The 18 Pro Max weighs 249 g, 16 g more than the 17 Pro Max’s 233 g.
- GoldPrivé’s current gold collections are built on the iPhone 18 Pro and Pro Max, in 24K Gold, Rose Gold, Platinum and 18K solid gold.

Quick Answer
The iPhone 18 Pro Max is a focused update: a faster A20 Pro chip, a variable-aperture main camera and six more hours of rated video playback, in the same 6.9-inch, 8.75 mm body. If your iPhone 17 Pro Max still lasts the day and you rarely shoot in difficult light, the difference is modest. If you want the longest battery life and the most flexible main camera Apple offers in a Pro Max, the upgrade delivers both.

Figures are Apple’s own, from the iPhone 17 Pro Max and iPhone 18 Pro Max technical specifications.
Chip and Performance
The iPhone 17 Pro Max runs the A19 Pro with a 6-core CPU and a 6-core GPU. The iPhone 18 Pro Max moves to the A20 Pro, which keeps a 6-core CPU layout but adds a seventh GPU core. Day to day, both are among the fastest phones available; the extra graphics core matters most in demanding games, video editing and on-device imaging work, and a newer chip generally stays current for longer.
Camera System: One Headline Change
The only hardware change to the camera system is the main camera’s variable aperture on the iPhone 18 Pro Max. At ƒ/1.48 it gathers more light than the 17 Pro Max’s fixed ƒ/1.78 lens, and stopping down to ƒ/2.8 or ƒ/4.0 keeps more of a close-up scene in focus. The 48MP ultra wide, the 48MP 4x telephoto and the 8x optical-quality zoom range are identical.
Video capability is also matched, with 4K Dolby Vision recording at up to 120 fps on both. If you shoot mostly with the telephoto or ultra wide, you will see little difference between the two generations.
Battery Life
Apple rates the iPhone 18 Pro Max at up to 45 hours of video playback and the iPhone 17 Pro Max at up to 39 hours, a six-hour improvement in the same body. That gain comes with extra weight: the 18 Pro Max is 16 g heavier at 249 g. Both charge wirelessly at up to 25W with MagSafe and Qi2.
Display and Design
The two phones share the same 6.9-inch OLED display with ProMotion up to 120Hz and 3000 nits of outdoor peak brightness, and the same aluminium unibody at 8.75 mm deep. Once customised, neither phone is water resistant.
Colours
Apple offers the iPhone 17 Pro Max in Silver, Cosmic Orange and Deep Blue, and the iPhone 18 Pro Max in Black, Silver, Glacier and Burgundy. Neither generation comes in real gold, rose gold or platinum from Apple; those finishes are available only through precious-metal customisation, compared in our rose gold iPhone guide.
