Apple iPhone 15 Pro vs Samsung Galaxy S23 Ultra
Our Verdict: The Samsung Galaxy S23 Ultra has a massively higher-resolution main camera, 200MP against the Apple iPhone 15 Pro's 48MP, and the S23 Ultra 5G has the bigger battery of the two, 5000mAh against 3274mAh, but capacity doesn't compare cleanly across iOS and Android, so it isn't a battery-life verdict on its own. The S23 Ultra 5G has the stronger screen, bigger at 6.8" against 6.1" and sharper at 500 PPI, and the iPhone 15 Pro 5G goes up to 1TB of storage, where the S23 Ultra 5G tops out at 512GB. The S23 Ultra 5G doesn't just win on price; it holds its own on specs too, which makes it the easy pick unless something specific draws you to the iPhone 15 Pro 5G.
Over a full contract, the S23 Ultra 5G works out around £746 all-in, about £116 less than the iPhone 15 Pro 5G.
