Apple iPhone 16 vs Samsung Galaxy S25 Ultra

Our Verdict: Hardware priorities split the decision here, with the Apple iPhone 16 strongest for the lighter 170g body versus 219g and the Samsung Galaxy S25 Ultra stronger for the larger 6.8" screen versus 6.1", the higher-resolution 200MP rear camera against 48MP, up to 1TB storage. The Apple iPhone 16 is currently cheaper on the lowest total contract cost at about £489, roughly £101 less than the Samsung Galaxy S25 Ultra. Software preference matters as well, because this is an iOS versus Android choice as much as a hardware comparison. That makes the Apple iPhone 16 the value-led pick, unless the larger 6.8" screen versus 6.1" on the Samsung Galaxy S25 Ultra is worth paying extra for.

The iPhone 16 is the cheaper one to own: around £693 over a typical contract, £147 less than the S25 Ultra.
