Samsung Galaxy S20 5G vs Samsung Galaxy S26 Ultra
Our Verdict: The Galaxy S26 Ultra is six years newer than the Galaxy S20 5G, and it shows in the specs. The S26 Ultra has a massively higher-resolution main camera, 200MP against the S20 5G's 64MP, and there's more battery in the S26 Ultra, 5000mAh to 4000mAh, which usually means longer between charges.
