Samsung Galaxy S20 4G vs Samsung Galaxy S25+
Our Verdict: There's five years between the Galaxy S20 4G and the Galaxy S25+, so the Galaxy S25+ is ahead on most things. The S20 4G has a noticeably higher-resolution main camera, 64MP against the S25+'s 50MP, and only the S25+ is a 5G phone; the S20 4G maxes out at 4G. The S25+ packs the bigger battery, 4900mAh against 4000mAh, which usually means longer between charges, and the S25+ has the bigger screen at 6.7" against 6.2", while the S20 4G has the sharper one at 566 PPI. The S25+ is the better phone; upgrade from the S20 4G if you want the newer hardware, or hold on if yours still does the job.
If you'd rather pay up front, the S20 4G is the cheaper buy at £185 SIM-free.
