About the Xiaomi Redmi Note 15
The Redmi Note 15 is the entry point to Xiaomi's biggest-selling family, and it plays that role sensibly rather than chasing headline specs. You get a 6.77-inch AMOLED panel with a 120Hz refresh rate and a peak brightness figure that helps in bright sunlight, a Snapdragon 6 Gen 3 chip that handles everyday apps and light gaming without drama, and a 5,520mAh battery paired with 45W charging, which is quick for this end of the market. The 108MP main camera is stabilised and produces detailed daylight shots, though the 8MP ultrawide alongside it is basic and there is no telephoto lens. Two things set it apart from rivals: it still takes a microSD card, so cheap storage expansion is on the table, and it has stereo speakers with Dolby Atmos. The trade-off for sitting at the entry point of the range is IP66 splash and dust protection rather than the full immersion rating the Pro models carry. It is a dependable, unflashy phone rather than an exciting one.

Xiaomi Redmi Note 15 Specifications
Spec Scores
Under £200 Phones · 118 phones
- Snapdragon 6 Gen 3
- Octa-core (4x2.4 GHz Cortex-A78 & 4x1.8 GHz Cortex-A55)
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.
- 6.77 inches
- 1080 x 2392 pixels (~388 ppi density)
- AMOLED, 120Hz, 3200 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
- 108 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.
- 20 MP front camera
- 1080p 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.
- 5,520 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.
