About the Xiaomi Redmi 15 4G
The Redmi 15 4G is Xiaomi's most affordable entry in the Redmi 15 family, delivering the same impressive 7,000mAh battery and expansive 6.9-inch display as its 5G sibling but at a noticeably lower price. Powered by the Qualcomm Snapdragon 685 chipset, it handles everyday tasks such as social media, messaging, and video streaming without breaking a sweat, making it ideal for light to moderate users who do not need 5G connectivity. The Full HD+ IPS LCD panel runs at a fluid 144Hz refresh rate, which is rare at this price point and makes scrolling feel noticeably smoother. The 50MP dual camera captures solid photos in good light, and the 8MP selfie camera is perfectly fine for video calls. With IP64 splash resistance, Gorilla Glass 3 protection, 33W fast charging, and 18W reverse charging that lets the phone double as a power bank, the Redmi 15 4G is a genuinely practical smartphone for budget buyers who value battery endurance and screen size above all else. Sitting right at the entry level, it is one of the most compelling value propositions in the UK market.

Xiaomi Redmi 15 4G Specifications
Spec Scores
£200-£399 Phones · 195 phones
- Snapdragon 685
- Octa-core (4x2.8 GHz Cortex-A73 & 4x1.9 GHz Cortex-A53)
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.
- 6.9 inches
- 1080 x 2340 pixels
- IPS, 144Hz
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
- 1080p 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.
- 7,000 mAh
- 33W 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.
