Samsung Galaxy S20 4G vs Samsung Galaxy S26+

Our Verdict: The Galaxy S20 4G and the Galaxy S26+ are six years apart, which is enough for a real difference. The S20 4G has the better camera on paper, 64MP versus 50MP, and only the S26+ is a 5G phone; the S20 4G maxes out at 4G. The S26+ has the bigger battery of the two, 4900mAh against 4000mAh, which should mean longer between charges in day-to-day use, and the S26+ has the bigger screen at 6.7" against 6.2", while the S20 4G has the sharper one at 566 PPI. Coming from the S20 4G, the S26+ is a genuine upgrade rather than a token one.
