iPhone 15 vs iPhone 15 Pro: bottom line

Amy Axworthy, Which? mobile phones expert, says:

Amy Axworthy

'Beneath the surface, the iPhone 15 and iPhone 15 Pro are very similar phones. Both offer the same high resolution (2556 x 1179) 6.1-inch Super Retina display, are a similar physical size and have a similar sized battery. 

Key differentiators include a faster processor on the Pro, at least on paper, and an additional telephoto camera (for optical zoom) and depth camera, which should mean you can expect better photos. The key question, is whether that's worth the extra price.'

Why you can trust our mobile phones tests

Our reviews of the iPhone 15 and iPhone 15 Pro are different – we don't rate phones based on individual experience, but based on the ratings and results we receive from our independent lab, where phones are tested under identical conditions using cutting edge equipment, which means they're all directly comparable. We also purchase every phone we test ourselves, so you can trust that there is no bias in our scores.

  • A Which? overall score is made up by testing various criteria, from key ratings such as battery life, camera performance, ease of use, audio quality and durability. 
  • Behind each of those ratings includes more than 40 individual tests and checks that are weighted differently. This means that the most important things, such as the quality of your pictures and videos, will more greatly impact the score than features such as how easy it is to use the phone’s music player. 
  • To keep things simple, the most important scores are shown as star ratings out of five on each phone’s Test Results page, as an easy-to-compare list of strengths and weaknesses, so you can quickly work out whether a model is right for you.
