Comparison · iPhone 18 ProiPhone 18 Pro vs Pro Max: the full comparison
The two Pro models share most of their platform. Size, battery, weight and price are the real buying decisions.
For most people the choice is straightforward. iPhone 18 Pro is easier to carry and starts at £1,199. Pro Max gives you a 6.9-inch display, a larger battery and up to 43 hours of video playback, but starts at £1,299 and weighs more. Camera features are broadly shared, so do not buy Pro Max expecting a completely different camera system.
How to read this result
Tests are snapshots, not guarantees. When comparing phones, keep the method, software version, screen brightness, network and starting conditions in view. We update this page when better evidence appears.
What a fair test should show
Results only mean something when the conditions are visible. Look for the software version, brightness, network, temperature, battery health, starting charge and the exact endpoint. If a report leaves those details out, treat it as useful colour rather than a controlled comparison.
What this means for owners
iPhone 18 Pro has a published baseline of 6.3-inch Super Retina XDR OLED, ProMotion up to 120Hz and A20 Pro. Those specifications explain the platform, but they do not remove the differences created by signal strength, app mix, storage choice or personal habits. The practical conclusion should remain proportional to the evidence.
