About the Samsung Galaxy M55
The Galaxy M55 is a 2024 mid-ranger from Samsung's M series, and its selling point is unusual for a Samsung at this level: a Qualcomm Snapdragon 7 Gen 1 in place of an Exynos chip. SamMobile's review found it around 10-15% slower than the Exynos 1480 overall, but better supported by games, with Call of Duty allowing its Very High preset at the time. The 6.7-inch 120Hz Super AMOLED Plus screen is the other strength, and at 7.8mm and 180g it is slim for a phone with a 5,000mAh battery that lasted a full day of heavy use in the same testing. The compromises are clear. There is no IP rating, the frame and back are plastic, and the camera is the weak point: SamMobile reported a laggy camera app and night shots that take around seven seconds to capture, which often left them shaky. Its 50MP selfie camera did not noticeably beat Samsung's 32MP ones either. Samsung promised four Android upgrades and five years of security patches from its 2024 launch, so support runs into 2029, a shorter window than a current Galaxy A37 gets.

Samsung Galaxy M55 Specifications
Spec Scores
£200-£399 Phones · 203 phones
- Snapdragon 7 Gen 1
- Octa-core (1x2.4 GHz Cortex-A710 & 3x2.36 GHz Cortex-A710 & 4x1.8 GHz Cortex-A510)
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.
- 6.7 inches
- 1080 x 2400 pixels
- AMOLED, 120Hz, 1000 nits peak
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. Where DXOMARK has lab-tested the phone, its measured score replaces this estimate.
- 50 MP front camera
- 4K selfie video
Based on the image-processing tier (Apple Pro, Pixel Pro, Galaxy Ultra and Honor Magic lead on computational processing), sensor resolution in tiers rather than raw megapixels, autofocus, aperture and max selfie-video resolution. Calibrated against DXOMARK's selfie protocol.
- 5,000 mAh
- 45W 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.
