Apple has long stopped separating its Pro models by internals. Same chip, same cameras - the difference is size. But behind the size hides one more important parameter that people often forget about. More on it below.
Short answer
iPhone 18 Pro - if compactness and one-handed use matter to you. iPhone 18 Pro Max - if you watch a lot of video, play games, read on your phone and want maximum battery life.
Key differences
| Spec | iPhone 18 Pro | iPhone 18 Pro Max |
|---|---|---|
| Display | 6.3", 1206×2622 | 6.9", 1320×2868 |
| Dimensions | 150 × 71.9 × 8.75 mm | 163.4 × 78 × 8.75 mm |
| Weight | 211 g | 249 g |
| Battery | 4056 mAh | 5391 mAh |
The A20 Pro chip, 12 GB of RAM, up to 2 TB of storage, cameras (48 MP with variable aperture f/1.48-f/4.0, 48 MP ultra-wide, 48 MP 4× telephoto, 18 MP front), up to 3000 nits, Wi-Fi 7 - all the same.
Size and weight
249 g on the Pro Max is noticeable. After a week with it in my jeans pocket I start to understand why many people go back to the "regular" Pro. On the other hand, 6.9 inches is almost a small tablet: video, books and spreadsheets are much more pleasant to view.
Battery life
Here is the parameter I mentioned. A bigger body means a bigger battery: the Pro Max has 5391 mAh. The Pro Max is traditionally the longest-lasting iPhone of the year, and if you are the kind of person hunting for a socket by evening, that is a strong argument.
Cameras and performance
No difference. Both shoot and perform the same - A20 Pro, 7-core GPU, doubled Neural Engine. More about the chip on the A20 Pro page.
Verdict: who should buy which
- Compactness, one hand, lightness - 18 Pro.
- Video, games, reading, maximum battery life - 18 Pro Max.
- Photo and video are identical, so there's no need to choose by camera.
