Apple iPhone 15 Pro vs Apple iPhone 17 Pro

Our Verdict: The Apple iPhone 15 Pro has the clearer appeal for the lighter 187g body versus 206g; the Apple iPhone 17 Pro pushes back through the larger 6.3" screen versus 6.1", the sharper 18MP selfie camera, the larger 3988mAh 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 £475 less than the Apple iPhone 17 Pro. There is also much wider deal availability for the Apple iPhone 17 Pro, with 19,123 active deals versus 994. That makes the Apple iPhone 15 Pro the value-led pick, unless the larger 6.3" screen versus 6.1" on the Apple iPhone 17 Pro is worth paying extra for.

Over a full contract, the 15 Pro 5G works out around £862 all-in, about £164 less than the 17 Pro.
