iPhone 16 Pro Max vs iPhone 18 Pro Max

The iPhone 18 Pro Max costs $100 more at the 256GB tier than the 16 Pro Max did at launch, and it adds a $1,999 2TB variant that the earlier model does not offer.

The A20 Pro is built on a 2nm process versus 3nm for the A18 Pro, and it pairs a 7-core GPU with the same 6 CPU core count. A newer process node generally improves power efficiency, which can help sustained workloads, but this page compares specifications rather than benchmark results.

Both main sensors are 48MP, but the 18 Pro Max adds a variable aperture that can open wider in low light and stop down in bright conditions. Whether that hardware change shows up in your photos depends on shooting conditions and how Apple's processing uses it.

The 18 Pro Max raises telephoto resolution from 12MP to 48MP, but it lists 4x optical zoom instead of the 5x on the 16 Pro Max, with both capped at 25x digital zoom. You gain detail per shot on the newer phone while giving up some optical reach.

The 18 Pro Max carries an 18MP front camera with autofocus, while the 16 Pro Max uses a 12MP f/1.9 sensor. Autofocus is useful when you or the subject move closer to or further from the lens during video calls and selfies.

Both phones list the same 4,685 mAh capacity and 25W wireless charging, but wired charging triples from 20W to 60W and the 18 Pro Max adds reverse wireless charging. If you frequently top up midday, the charging speed is a larger practical change than the identical capacity suggests.

Both panels are 6.9 inches with 120Hz refresh rates and the same 1320 x 2868 resolution, but the 18 Pro Max is rated 800 nits brighter at peak. Higher peak brightness mainly helps readability in direct sunlight and HDR highlight rendering.

The 18 Pro Max adds a 2TB tier that the 16 Pro Max does not have. Both use NVMe storage and neither supports expansion, so the top capacity you buy is the ceiling.

Our data lists the iPhone 16 Pro Max as discontinued and the iPhone 18 Pro Max as available. In practice that means new 16 Pro Max stock depends on remaining inventory, while the 18 Pro Max can be bought new across four storage tiers.

Is the iPhone 18 Pro Max worth upgrading to from the iPhone 16 Pro Max?

It depends on which specs you value. The 18 Pro Max brings a 2nm A20 Pro chip (versus 3nm), a variable aperture main camera, a 48MP telephoto, 60W wired charging (versus 20W), reverse wireless charging, 2,800-nit peak brightness (versus 2,000 nits), and a 2TB option. Battery capacity (4,685 mAh), weight (227 g), display size (6.9 inches), and update commitment (6 years) are unchanged, so you are paying $100 more at 256GB for camera, charging, and chip changes.

What is different about the cameras?

Both phones use 48MP main and 48MP ultrawide sensors. The 16 Pro Max has a fixed f/1.78 aperture and a 12MP f/2.8 telephoto with 5x optical zoom, while the 18 Pro Max adds a variable f/1.48-f/4.0 aperture and a 48MP f/2.8 telephoto with 4x optical zoom. Front cameras go from 12MP f/1.9 to 18MP f/1.9 with autofocus. Both record 4K at 120fps with ProRes.

Do both phones have the same battery?

Both list a 4,685 mAh capacity and 25W wireless charging. The difference is wired charging: 20W on the iPhone 16 Pro Max versus 60W on the iPhone 18 Pro Max. The 18 Pro Max also supports reverse wireless charging, which the 16 Pro Max does not. The 16 Pro Max uses a Li-Ion battery type while the 18 Pro Max is listed as Li-Po.

How much do they cost and how much storage do they offer?

The iPhone 16 Pro Max started at $1,199 for 256GB ($1,399 for 512GB, $1,599 for 1TB). The iPhone 18 Pro Max starts at $1,299 for 256GB, $1,499 for 512GB, $1,699 for 1TB, and $1,999 for 2TB. Neither phone supports expandable storage.

How long will both phones receive updates?

Both the iPhone 16 Pro Max and iPhone 18 Pro Max are listed with 6 years of OS updates and 6 years of security updates. The 16 Pro Max launched on iOS 18, while the 18 Pro Max launched with a newer iOS version in September 2026, so the 18 Pro Max starts its support life later.
