About the Xiaomi Redmi 12

The Redmi 12 is Xiaomi's affordable all-rounder for 2023, delivering a large 6.79-inch FHD+ display, a capable 50MP camera, and solid all-day battery life at a price that undercuts most of the competition. While it sits in the budget segment, it packs features that were mid-range territory just a generation ago, including a 90Hz refresh rate, an 8MP ultrawide camera, and up to 256GB of storage with microSD expansion. The MediaTek Helio G88 chipset handles everyday tasks smoothly, from messaging and social media to web browsing and video streaming, making it a reliable daily driver for undemanding users. The 50MP main camera captures good-quality photos in daylight with natural colours, and the ultrawide adds useful flexibility for group shots and landscapes. A 5,000mAh battery ensures comfortable all-day endurance, though the 18W charging speed is slow by modern standards and takes over two hours for a full charge. The build combines a plastic frame with a textured back available in several attractive colours. For students, first-time smartphone buyers, and anyone who wants a large-screen phone with a competent camera and reliable performance without stretching their budget, the Redmi 12 delivers solid everyday value.

Frequently Asked Questions

Is the Redmi 12 worth buying?
The Redmi 12 is worth buying as an affordable everyday phone. Its large FHD+ display, 50MP camera with ultrawide, and 5,000mAh battery provide a solid core experience for basic tasks. However, the slow 18W charging and modest Helio G88 chipset mean it is best suited for undemanding users. If you need faster charging or 5G, consider newer alternatives.
How good is the Redmi 12 camera?
The 50MP main camera produces good-quality photos in daylight with natural colours and reasonable detail for social media sharing. The 8MP ultrawide adds useful versatility for wider scenes and group shots. Low-light performance is limited without OIS, but the camera is perfectly adequate for everyday photography at this price point.
Does the Redmi 12 have a big screen?
Yes, the Redmi 12 features a 6.79-inch FHD+ display with a 90Hz refresh rate, making it one of the larger screens in the budget segment. The Full HD+ resolution ensures sharp text and images, and the 90Hz refresh rate provides smoother scrolling than standard 60Hz panels. It is excellent for video watching and browsing.
How long does the Redmi 12 battery last?
The 5,000mAh battery provides comfortable all-day use for typical tasks like messaging, social media, and web browsing. Most users will easily get through a full day with battery to spare. The main weakness is the 18W charging speed, which takes over two hours to fully recharge the battery.
Does the Redmi 12 support expandable storage?
Yes, the Redmi 12 supports microSD card expansion up to 1TB alongside its 128GB or 256GB internal storage. This is a valuable feature for users who store lots of photos, music, or videos, and it ensures you will not run out of space even on the base storage model.
How does the Redmi 12 compare to the Redmi 14C?
The Redmi 14C offers a larger 6.88-inch 120Hz display versus the Redmi 12's 6.79-inch 90Hz panel, a slightly bigger 5,160mAh battery, and runs a newer Android version. The Redmi 12 fights back with a sharper FHD+ resolution versus HD+, an 8MP ultrawide camera that the 14C lacks, and the more established Helio G88 chipset. The 14C is the newer phone with a smoother display, while the 12 has a sharper screen and more versatile camera. Compare Redmi 14C 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.
