The 18 Pro Max gets the biggest battery jump in iPhone history. Here is everything else that changed, and what did not.
The upgrade is battery. The iPhone 18 Pro Max gets up to 45 hours of video against 39, charges faster and adds the variable-aperture camera. It costs you 16 g. If your iPhone 17 Pro Max already gets you through the day, keep it.

Round by round
Up to 45 hours of video against 39. Apple calls it the biggest battery jump ever on iPhone. Six extra hours is more than a Toronto to Vancouver flight.
50% in about 15 minutes with a 60W adapter, against 20 minutes with 40W.
The main camera adds a variable aperture and manual controls. Zoom and selfie cameras are the same.
A20 Pro with a 7-core GPU. You'll feel it in long gaming sessions.
233 g against 249 g. 16 g is about two and a half loonies. The extra weight is the bigger battery.
Same 6.9-inch 3000-nit screen and same aluminum design.
The 18 Pro Max wins on paper. The real question is whether you'll feel it. If your 17 Pro Max already lasts all day, you won't.
Skip it if
Skip the iPhone 17 Pro Max if
- You end most days under 20%
- You want the newest camera
- You play long gaming sessions
Skip the iPhone 18 Pro Max if
- You own a 17 Pro Max and its battery is still healthy
- The 17 Pro Max already feels heavy in your hand
- You mostly text, browse and stream
SOur take
This is the most honest upgrade of the year for heavy users: the battery gain is big and you'll feel it every day.
For everyone else on a 17 Pro Max, it's the same phone with a heavier body. Keep yours, or trade it in when the battery starts to fade.
