How to pick your Galaxy S23 deal

Two numbers decide the real cost: the monthly price and any upfront fee. A low monthly with a high upfront can cost more overall than a flat deal, so sort by effective monthly cost to compare like for like across the full contract. Pick a data allowance that matches how much you actually use rather than the biggest on offer, and choose a contract length you are happy to keep. If you already have a phone you like, a SIM-only plan is usually cheaper than a fresh contract.

Camera and display

The 6.1-inch AMOLED display is bright and sharp for video, games and everyday browsing, and the compact size suits one-handed use and smaller pockets. The 50MP main camera, part of a triple lens setup, takes strong photos in good light and holds up well after dark. The 12MP front camera is fine for video calls and selfies. As an older flagship, it cannot match the very latest models for low-light detail, but for everyday shots it still does the job well.

Performance and battery

The Galaxy S23 handles daily apps, browsing and most games without fuss, though its older chip will feel a step behind the newest phones over time. The 3,900 mAh battery comfortably lasts a full day for most people, with lighter users stretching into a second day. At 168 g it is light and easy to carry. It shipped with Android 13, so check the current update support before you buy if long-term software matters to you.

Galaxy S23 vs Galaxy S22

The Galaxy S22 is the previous generation, so the S23 is the slightly newer and faster of the two. Both share the same compact, one-handed shape and a similar everyday feel, so the day-to-day experience is close. The decision usually comes down to price. Choose the S23 if the gap is small and you want the newer model, or the S22 if it works out meaningfully cheaper for what you need.

How much storage do you need?

The Galaxy S23 comes with 128GB. That suits most people, with room for photos, apps and a few offline downloads. There is no memory card slot, so you cannot add space later. If you keep large video libraries or many games on the device, you may need to manage what you store, or pick a phone with a bigger base capacity from the start. Cloud backups can help free up room without losing your files.

Pros

  • Compact 6.1-inch AMOLED screen, easy one-handed
  • Capable 50MP main camera for everyday shots
  • 5G ready across UK networks
  • Flagship features for less now it is older

Cons

  • Older chip than the newest models
  • 128GB storage with no memory card slot
  • Fewer years of software updates ahead

Our verdict

The Galaxy S23 is a smart pick if you want a compact flagship for less and can live with an older chip and shorter update runway.
