About the Xiaomi Redmi A3

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 under £80 in the UK, 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.

Frequently Asked Questions

Is the Redmi A3 worth buying?
The Redmi A3 is well worth buying if you need a basic, affordable smartphone. The 90Hz display with Gorilla Glass 3 feels noticeably smoother and more durable than typical phones at this price, and the 5,000mAh battery easily lasts a full day. For under £80, it delivers a surprisingly polished experience for essential tasks.
How good is the Redmi A3 camera?
The 8MP rear camera takes acceptable photos in good lighting for social media sharing and quick snapshots. It struggles in low light, and there is no ultrawide or advanced processing. The 5MP selfie camera covers video calls and basic selfies. Photography is not the A3's strength, but it handles the basics.
Does the Redmi A3 have Gorilla Glass?
Yes, the Redmi A3 features Corning Gorilla Glass 3 on the front, which is a notable inclusion for an ultra-budget phone. This provides meaningful protection against scratches and minor drops, giving the A3 better durability than most competitors at its price.
Does the Redmi A3 support 5G?
No, the Redmi A3 is a 4G-only device. At its ultra-budget price point, 5G is not expected. For basic browsing, streaming, and social media, 4G connectivity is more than sufficient.
How long does the Redmi A3 battery last?
The 5,000mAh battery combined with the efficient HD+ display and Android Go software easily lasts a full day, often stretching to a day and a half for light users. Charging is limited to 10W, so plan for overnight charging rather than quick top-ups.
How does the Redmi A3 compare to the Redmi A2?
The Redmi A3 improves on the A2 in several key areas: a larger 6.71-inch display versus 6.52 inches, a smoother 90Hz refresh rate versus 60Hz, Gorilla Glass 3 protection which the A2 lacks, updated Android 14 software, and more generous storage up to 128GB. Battery, chipset, and cameras remain similar. The A3 is the better buy unless you need the absolute cheapest option. Compare Redmi A2 deals.

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 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.
