Apple iPhone 13 vs Samsung Galaxy S23 Ultra

Our Verdict: The Samsung Galaxy S23 Ultra has a far higher-resolution main camera, 200MP against the Apple iPhone 13's 12MP, and the S23 Ultra 5G packs the bigger battery, 5000mAh against 3227mAh, though iOS and Android manage power differently, so more mAh doesn't always mean longer battery life. The S23 Ultra 5G has the stronger screen, bigger at 6.8" against 6.1" and sharper at 500 PPI, and the iPhone 13 is the lighter phone at 173g against 233g. Get the S23 Ultra 5G if those extras are worth it to you; otherwise the iPhone 13 covers the basics for less.

Over a full contract, the iPhone 13 works out around £433 all-in, about £312 less than the S23 Ultra 5G.
