Samsung Galaxy S20 4G vs Samsung Galaxy S26 Ultra
Our Verdict: The Galaxy S26 Ultra is six years newer than the Galaxy S20 4G, and it shows in the specs. The S26 Ultra has the better camera on paper, 200MP versus 64MP, and only the S26 Ultra is a 5G phone; the S20 4G maxes out at 4G. The S26 Ultra has the bigger battery of the two, 5000mAh against 4000mAh, which usually means longer between charges, and the S26 Ultra has the bigger screen at 6.9" against 6.2", while the S20 4G has the sharper one at 566 PPI. The S26 Ultra is the better phone; upgrade from the S20 4G if you want the newer hardware, or hold on if yours still does the job.
Buying outright, the S20 4G starts at £175 SIM-free.
