Apple iPhone 12 vs Samsung Galaxy S23 Ultra

Our Verdict: The Samsung Galaxy S23 Ultra has the better camera on paper, 200MP versus 12MP, and there's more battery in the S23 Ultra 5G, 5000mAh to 2815mAh, 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 storage goes higher on the S23 Ultra 5G, up to 512GB against 256GB. Only pay up for the S23 Ultra 5G if you'll use what it offers; if not, the Apple iPhone 12 makes more sense.

The iPhone 12 is the cheaper one to own: around £515 over a typical contract, £233 less than the S23 Ultra 5G.
