About the Samsung Galaxy M23
The Galaxy M23 is the entry point into Samsung's 5G-capable M range, and it earns its place mostly on one decision: Samsung used Qualcomm's Snapdragon 750G here rather than a cheaper in-house chip. That gives it a more even, predictable feel in everyday use than you might expect at this level, and it handles 5G on all UK networks. Around that sits a familiar budget Samsung recipe - a 6.6-inch 120Hz LCD, a 5,000mAh battery, a 50MP main camera and a plastic body. The screen is the compromise. It is a TFT LCD, so blacks look grey and outdoor brightness is ordinary next to any AMOLED phone, and the 120Hz refresh rate does more for the perception of speed than the panel quality does. Where it holds up well is practicality: a 3.5mm headphone jack, a dedicated microSD slot so a memory card does not cost you a second SIM, and battery life that genuinely runs past a full day. It is a sensible, unshowy phone rather than an exciting one.

Samsung Galaxy M23 Specifications
Spec Scores
£200-£399 Phones · 194 phones
- Snapdragon 750G 5G
- Octa-core (2x2.2 GHz Kryo 570 & 6x1.8 GHz Kryo 570)
Based on calibrated CPU benchmark rankings (60%) and GFXBench GPU scores (40%). Apple chipsets included via editorial calibration since AnTuTu under-represents Apple's architecture.
- 6.6 inches
- 1080 x 2408 pixels
- TFT, 120Hz
Based on panel type (LTPO is the modern flagship gold standard), resolution, refresh rate, peak brightness, screen size, and HDR10+ / Dolby Vision support. Marketing peak-brightness claims are capped at 3500 nits to prevent inflation.
- Single camera setup
- 50 MP main camera
- 4K video recording
Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.
- 8 MP front camera
- 1080p selfie video
Based on selfie megapixels and max selfie-video resolution.
- 5,000 mAh
- 25W wired
Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
