The Xiaomi Redmi 4X remains available in the UK market as sealed new stock, offering budget-conscious buyers an affordable smartphone option released in 2017. Despite its age, the device continues to appear on price comparison platforms and retailer listings, presenting a unique opportunity for those seeking a capable secondary phone or backup device.

Understanding where to purchase this unlocked dual SIM smartphone and what prices to expect requires careful consideration of the current marketplace. Multiple UK retailers list the device, though availability fluctuates and prices vary across platforms.

This guide compiles the key purchasing information, specifications, and practical considerations for anyone looking to buy a Xiaomi Redmi 4X in the United Kingdom today.

Where to Buy Xiaomi Redmi 4X in the UK

Several UK-based retailers maintain listings for the Xiaomi Redmi 4X, with stock primarily consisting of boxed, sealed units from 2017. BulkMobiles offers direct purchasing through their product page, while PriceSpy aggregates prices from multiple sellers for comparison purposes.

Verified Purchase Points

The most reliable sources include BulkMobiles.co.uk for sealed stock, PriceSpy.co.uk for price comparisons, and established marketplace sellers on eBay.co.uk with strong feedback ratings.

Amazon.co.uk also lists Xiaomi Redmi 4X devices, though buyers should exercise caution as newer Xiaomi models frequently appear alongside older stock. Searching precisely for “Redmi 4X” rather than general “Xiaomi Redmi” queries helps isolate the correct model.

Current Prices for Xiaomi Redmi 4X

Price data collected from UK retailers indicates the Xiaomi Redmi 4X typically ranges between £135 and £139 for sealed, unlocked units. This pricing applies to the standard 3GB RAM and 32GB storage configuration, which represents the most commonly available variant in the current market.

PriceSpy.co.uk serves as a useful aggregation tool for monitoring fluctuations in real-time. Prices can vary by £5-10 depending on the retailer, seller reputation, and whether the unit includes original accessories and packaging.

Factors Affecting Pricing

Several variables influence the final purchase price. Sellers offering “boxed sealed” units command slightly higher prices than loose devices, reflecting the perceived value of new, unopened stock. Shipping costs also vary, with some retailers offering free UK delivery while others add £2-5 for postage.

Seller ratings play a significant role in price differentiation. Established sellers with hundreds of positive reviews may price slightly higher, but offer greater buyer protection through platform guarantees.

Price Awareness

The £135-£139 range represents current market pricing, though prices fluctuate based on seller, condition, and bundle inclusions. Comparing prices across at least three retailers before purchasing helps secure the best deal.

Xiaomi Redmi 4X Key Specifications

The Redmi 4X debuted in 2017 as a budget-friendly option featuring a 5-inch HD display with 720 x 1280 pixel resolution and 294 ppi pixel density. Processing power comes from a 1.4GHz octa-core Qualcomm Snapdragon 435 processor paired with 3GB RAM.

Performance Capabilities

Testing from the period indicates the device handles multitasking smoothly without noticeable lag, even with multiple apps running in the background. Gaming performance was described positively, with most games running at higher graphics settings without overheating concerns.

The 4100mAh battery stands as a particular strength, consistently delivering 25-30% capacity remaining after a full day of average use. Heavy users report approximately two days of operation, while lighter usage can extend battery life to four days. Full charging does require over two hours using the standard charger.

Hardware Summary

The Snapdragon 435 processor, while dated by 2024 standards, remains adequate for everyday tasks including web browsing, social media, messaging, and streaming video at standard resolutions.

Camera and Display

The rear camera features 13 megapixels with Phase Detection Autofocus and HDR support. While not flagship-quality, the camera satisfies basic photography needs for social media and casual capture. The front-facing camera provides 5 megapixels for selfies and video calls.

Display brightness has been noted as less impressive than competitors in the same price bracket, though the panel itself renders text sharply and colours vibrantly for a budget device. Reviewers described visibility as adequate for indoor use while noting limitations in direct sunlight.

Availability and Storage Options for Redmi 4X

The primary configuration available in UK listings features 3GB RAM paired with 32GB internal storage. This base storage can be expanded via microSD card up to 128GB, though users must sacrifice one SIM slot when adding memory cards due to the hybrid tray design.

Network and SIM Configuration

All units available as “unlocked” support dual SIM functionality, accepting one Nano-SIM and one Micro-SIM card. This configuration provides flexibility for users managing multiple phone numbers or seeking to combine personal and work lines on a single device.

Connectivity options include GPS, A-GPS, GLONASS positioning systems, Bluetooth 4.2, and network support spanning 2G, 3G, and 4G bands. Buyers should verify their specific network requirements match these capabilities, particularly regarding 4G frequency bands used by UK carriers.

Important Consideration

Using a microSD card for additional storage requires giving up the second SIM slot. Users who need both dual SIM functionality and expanded storage must choose between these options.

Build and Design

The device combines metal and plastic construction, weighing 150 grams with dimensions of 8.7mm thickness. A rear-mounted fingerprint scanner provides biometric security, while the gold colour option remains commonly available in current stock.

Redmi 4X Timeline

Understanding the device’s history helps contextualise its current market position and availability as new old stock.

  1. — Xiaomi launches the Redmi 4X as a budget-oriented smartphone targeting emerging markets and price-conscious consumers globally
  2. — Initial reviews praise battery life, processing performance for the price, and unlocked dual SIM flexibility

What We Know and What Remains Unclear

Certain aspects of the Xiaomi Redmi 4X purchasing process are well-documented, while others require buyer diligence to verify independently.

Understanding the Redmi 4X Appeal

The continued availability of the Xiaomi Redmi 4X in 2024 reflects several practical advantages for specific user scenarios. Budget-conscious buyers appreciate the sub-£140 price point for a functioning smartphone with reasonable specifications, particularly those seeking a reliable backup device or a first smartphone for younger users.

The unlocked status removes carrier restrictions, allowing immediate use with any UK network provider. Dual SIM capability proves valuable for users managing personal and business numbers or those frequently travelling internationally who require local SIM cards alongside their primary number.

However, perspective matters. By 2024 standards, the Snapdragon 435 processor and Android 6.0.1 operating system show their age. Security updates have likely ceased, and compatibility with newer applications may become problematic over time. Buyers prioritising modern features, current security patches, or longer software support should consider newer budget alternatives from Xiaomi’s current lineup.

Sources and References

Information in this guide draws from retailer listings, price aggregation platforms, and historical device reviews. Primary sources include product pages from BulkMobiles, price comparison data from PriceSpy, and specification details from GSMArena.

GSMArena provides comprehensive technical specifications for the Xiaomi Redmi 4X, including processor details, network band support, and physical dimensions.

Additional specification context comes from historical reviews published during the device’s initial launch period, cross-referenced against current retail listings to ensure accuracy regarding available configurations.

Summary

The Xiaomi Redmi 4X remains purchasable in the UK through established retailers and marketplace platforms, with prices consistently ranging between £135 and £139 for sealed, unlocked units. The device offers practical value through its 4100mAh battery, dual SIM capability, and expandable storage, though buyers should temper expectations regarding modern software support and performance standards. Verifying seller ratings and comparing prices across multiple platforms before purchasing helps ensure a satisfactory transaction. Those interested in device maintenance may find guidance on clearing cache on Samsung devices useful for general smartphone optimisation practices.
