iPhone 14 Pro Max vs iPhone 15 Pro Max: bottom line

Amy Axworthy, Which? mobile phones expert, says:

Amy Axworthy

'Apple made as big of a deal about the iPhone 15 Pro Max’s advancements as you’d expect. Announcements included a new titanium design, an upgraded chipset, extra zoom software for its cameras, and a new action button for personalised shortcuts. But when it boils down to if the upgrades are worth the extra money, it’s a no from me. 

Both devices are a joy to use and have market-leading specifications in their screen quality and cameras, and plus, they have similar-sized batteries.'

Why you can trust our mobile phones tests

Our reviews of the iPhone 14 Pro Max vs iPhone 15 Pro Max 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.
