The Redmi A3 is Xiaomi's refreshed entry-level smartphone for 2024, offering meaningful upgrades over its predecessor while keeping the price firmly in ultra-budget territory. The most noticeable improvement is the larger 6.71-inch display with a 90Hz refresh rate and Corning Gorilla Glass 3 protection — a rare inclusion at this price that adds genuine durability. Running Android 14 Go edition on the familiar MediaTek Helio G36 chipset, it delivers a clean, responsive experience for basic tasks like messaging, browsing, and social media. The 5,000mAh battery provides comfortable all-day endurance, and storage options up to 128GB with microSD expansion mean you are unlikely to run out of space. The 8MP rear camera and 5MP front camera are basic but functional for quick snaps and video calls. At the very bottom of the UK price ladder, the Redmi A3 hits a sweet spot for buyers who want a modern-looking phone with a smooth display and reliable battery life without spending more than they need to. It is a smart pick for children, elderly family members, or as a dependable backup device.

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.
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.
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.
Based on selfie megapixels and max selfie-video resolution.
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.
