Samsung Galaxy S20 FE 5G vs Samsung Galaxy S25 Ultra

Our Verdict: If you've got the Galaxy S20 FE 5G, the Galaxy S25 Ultra is four years of updates on from it. The S25 Ultra has a dramatically higher-resolution main camera, 200MP against the S20 5G Fan Edition's 12MP, and the S25 Ultra packs the bigger battery, 5000mAh against 4500mAh, which should mean longer between charges in day-to-day use. The S25 Ultra has the stronger screen, bigger at 6.8" against 6.5" and sharper at 505 PPI, and the S25 Ultra goes up to 1TB of storage, where the S20 5G Fan Edition tops out at 256GB. The S25 Ultra is the better phone; upgrade from the S20 5G Fan Edition if you want the newer hardware, or hold on if yours still does the job.

If you'd rather pay up front, the S20 5G Fan Edition is the cheaper buy at £149 SIM-free.
