Samsung Galaxy S20 5G vs Samsung Galaxy S20 Ultra 5G
Our Verdict: These are two phones from the same range, with the Galaxy S20 Ultra 5G sitting above the Galaxy S20 5G. The S20 Ultra 5G has a considerably higher-resolution main camera, 108MP against the S20 5G's 64MP, plus a 40MP selfie camera against 10MP, and the S20 Ultra 5G packs the bigger battery, 5000mAh against 4000mAh, which usually means longer between charges. The S20 Ultra 5G has the bigger screen at 6.9" against 6.2", while the S20 5G has the sharper one at 566 PPI, and the S20 Ultra 5G offers up to 512GB of storage versus 128GB on the S20 5G. The S20 Ultra 5G is the one to have if you want what it adds, but the S20 5G is the smarter buy if you'd rather keep the money.
If you'd rather pay up front, the S20 5G is the cheaper buy at £129 SIM-free.
