Samsung Galaxy S25 Ultra vs Samsung Galaxy A37

The Galaxy S25 Ultra is the better phone on every spec that matters: a sharper 6.9-inch LTPO screen, a 200MP camera system, a faster chip, wireless charging and a titanium build. The Galaxy A37 is the sensible pick for someone who wants a big 120Hz AMOLED screen, a 50MP camera and long software support without paying flagship money. Owners rate the S25 Ultra very highly and praise its camera and display; reviewers call the A37 a solid, easy everyday phone but note it lacks wireless charging and can feel sluggish under load.

  • Choose the Galaxy S25 Ultra if you want the best camera, display and performance Samsung makes and you keep phones for years.
  • Choose the Galaxy A37 if you want a large smooth screen, all-day battery and six years of updates at mid-range money.

  • 4.7 / 5179,000 ratings

Rated 4.7 out of 5 from about 179,000 ratings, the S25 Ultra is widely liked for its screen, battery life and camera flexibility. Owners' main complaints are its size and weight and the modest step up from the previous model.

Questions and answers

Which is better for photos?
The S25 Ultra. Its 200MP main sensor, telephoto zoom and stronger processing beat the A37's 50MP triple camera, especially in low light and at distance. The A37 takes good shots in good lighting.
Is the A37 enough for everyday use?
Yes for calls, messaging, video and casual games. Reviewers say it handles daily tasks smoothly, but the 6GB RAM and Exynos chip slow down under heavy multitasking or demanding games.
Which lasts longer?
The S25 Ultra has the sturdier titanium build and one extra year of updates. The A37 also has IP68 and Gorilla Glass Victus+, so it is no fragile phone, and six years of updates is long for its class.
Is the S25 Ultra worth stepping up to?
If you care about camera quality, a sharper screen, wireless charging or the S Pen, yes. If you mainly browse and stream, the A37 covers that well.
Does the A37 support wireless charging?
No. It charges at 45W over USB-C only. The S25 Ultra supports wireless charging and reverse wireless charging for accessories.
Which is easier to carry?
The A37. It weighs 6.91 oz against roughly 7.7 oz for the S25 Ultra, and its 6.7-inch screen is slightly smaller.
