iPhone 18 Pro Max: everything to know before you buy

Price, battery, cameras, weight and the checks to make before you pay, based on Apple’s launch details and early reviews.

The short version

Apple announced the iPhone 18 Pro and Pro Max on September 9, 2026, and they went on sale on September 18. Reviewers describe the Pro Max as a strong upgrade rather than a revolution: faster, longer-lasting, and with a more flexible main camera. If you already own an iPhone 17 Pro Max, the jump is modest. If your phone is two or three years old, it is a big step up.

Price, storage and colours

In the US the iPhone 18 Pro Max starts at $1,299 for 256GB, which is $100 more than the smaller 18 Pro at $1,199. Storage runs from 256GB to 1TB, and for the first time Apple also sells a 2TB version. The colours are Black, Silver, Glacier and Burgundy. Prices in other countries differ, and some third-party spec sites list higher figures, so check your local Apple Store or an authorised reseller instead of trusting a spec sheet.

What is actually new

A20 Pro chip. It is Apple’s first 2-nanometre chip, paired with 12GB of RAM. Early reviews call it the fastest phone chip available.
Variable aperture on the main camera. The 48MP main camera can change how much light it lets in. Reviewers say it helps with depth and low light, though one review found it more of a gadget than a breakthrough.
Three 48MP rear cameras (main, ultrawide and a longer telephoto) and an 18MP front camera.
A bigger battery. Apple rates the Pro Max at up to 45 hours of video playback, against 36 hours for the 18 Pro.
Better cooling. A new vapor chamber spreads heat away from the chip.
Smaller Dynamic Island and iOS 27 out of the box.

Battery and heat: what reviewers found

Battery life is the most praised part. Several reviews call it best in class, with the Pro Max easily lasting more than a day. Heat is better controlled than before, but not solved. One photographer who filmed for hours in desert temperatures above 30°C still saw overheating. If you shoot long videos in hot weather, which is common in many places, expect the phone to slow down or warn you. For settings that stretch any phone’s battery, see our battery guide.

Size and weight

The Pro Max has a 6.9-inch screen and weighs about 249g, and reviewers repeatedly call it heavy. It is great for video and reading, but tiring in one hand. Hold one in a shop before you commit. Some reviewers also noted that the Burgundy finish picks up fingerprints.

Check these before you pay

SIM type. Reports say the Pro models use eSIM. Confirm that your mobile network supports eSIM and that the phone you are buying works with it.
Where it was sold. Buy from Apple or an authorised reseller so the warranty is valid in your country. Avoid unusually cheap imports.
Storage. 256GB is enough for most people who use cloud photo backup. Pay for more only if you shoot lots of video.
Your current phone. Check the trade-in value, and compare with the cheaper 18 Pro before choosing the larger model.
Case and charger. The box includes a USB-C cable but no charger, so budget for one.

Who should buy it, and who should skip it

Buy it if you want the longest battery life and the biggest iPhone screen, and you watch or film a lot. Think twice if you want a lighter phone (the 18 Pro is the better fit), or if you already have last year’s Pro Max. Apple has also launched a foldable, the iPhone Duo, from $1,999, but it is a different kind of device.
