Amy Axworthy, Which? mobile phones expert, says:

The battle of Apple and Samsung’s flagship phones has continued for over a decade, and both of these phones are some of the best on the market. If I had to choose which beats the other in the closest of photo finishes, it’s the Samsung S24 Ultra that takes the gold.

With enviable specifications on both phones, it’s best to make your decision based on if you’d prefer an iPhone or Android phone. For example, it’s worth considering their compatibility with your other tech products when deciding, such as smartwatches and tablets.

Why you can trust our mobile phones tests

Our reviews of the iPhone 15 Pro Max vs Samsung Galaxy S24 Ultra 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.
