Samsung Galaxy A56 vs Samsung Galaxy S20 4G

Our Verdict: Same maker, different budgets: the Galaxy S20 4G is the cheaper option and the Galaxy A56 the premium one. The S20 4G has a clearly higher-resolution main camera, 64MP against the A56's 50MP, and the A56 supports 5G while the S20 4G tops out at 4G. There's more battery in the A56, 5000mAh to 4000mAh, which usually means longer between charges, and the A56 has the bigger screen at 6.7" against 6.2", while the S20 4G has the sharper one at 566 PPI. Only pay up for the A56 if you'll use what it offers; if not, the S20 4G makes more sense.

If you'd rather pay up front, the S20 4G is the cheaper buy at £175 SIM-free.
