Apple iPhone 15 Pro vs Samsung Galaxy S26 Ultra

Our Verdict: Start with the practical differences: the Apple iPhone 15 Pro offers the lighter 187g body versus 214g, whereas the Samsung Galaxy S26 Ultra gives you the larger 6.9" screen versus 6.1", the higher-resolution 200MP rear camera against 48MP, the larger 5000mAh battery, with the usual caveat that capacity is not the whole battery-life story. The Apple iPhone 15 Pro is currently cheaper on the lowest total contract cost at about £468, roughly £431 less than the Samsung Galaxy S26 Ultra. There is also much wider deal availability for the Samsung Galaxy S26 Ultra, with 16,176 active deals versus 994. Software preference matters as well, because this is an iOS versus Android choice as much as a hardware comparison. That makes the Apple iPhone 15 Pro the value-led pick, unless the larger 6.9" screen versus 6.1" on the Samsung Galaxy S26 Ultra is worth paying extra for.

Over a full contract, the iPhone 15 Pro 5G works out around £634 all-in, about £362 less than the S26 Ultra.
