When someone searches for “redmi 4x to buy” in 2026, they’re often looking for an ultra-budget device or perhaps a niche solution. However, the reality of purchasing a smartphone originally released in 2017 means navigating significant compromises in performance, security, and software support. This article will help you understand if the Redmi 4X still holds any practical value today, or if your money is better spent elsewhere.
Last updated: July 9, 2026
Key Takeaways
- The Redmi 4X is an obsolete device for mainstream use in 2026, lacking current security updates and performance for modern apps.
- Its market value for a used unit typically ranges from $15 to $40, primarily found on secondary markets like eBay or Swappa.
- While incredibly cheap, its Snapdragon 435 processor and older Android versions severely limit its functionality.
- It may suit niche uses such as a simple backup phone, a dedicated media player, or for very basic, non-internet-dependent tasks.
- For daily use, even the cheapest new smartphones available in 2026 offer significantly better security, performance, and longevity.
Redmi 4X in 2026: A Realistic Overview
The Xiaomi Redmi 4X, initially launched in early 2017, was a popular budget smartphone in its day. It featured a Qualcomm Snapdragon 435 chipset, 2GB or 3GB of RAM, and a substantial 4100mAh battery for its class. Fast forward to July 2026, and these specifications are simply outdated for mainstream smartphone use.
In my years observing the smartphone market, devices typically have a practical lifespan of 3–5 years for daily drivers before performance and security become major issues. The Redmi 4X is now well beyond that window, serving more as a relic than a strong daily tool.
Understanding its age is paramount when considering a Redmi 4X to buy. It operates on an older version of Android (typically Android 6.0 Marshmallow, upgradable to 7.1 Nougat, with unofficial ROMs potentially reaching Android 8.1 Oreo), meaning it receives no official security updates or new feature support from Xiaomi or Google.
Where to Find and What to Pay for a Redmi 4X
Finding a new Redmi 4X in 2026 is virtually impossible. The market for this device exists almost exclusively in the used and refurbished sectors. Online marketplaces like eBay and Swappa are your primary hunting grounds, where listings for the Xiaomi Redmi 4X still appear.
Prices vary significantly based on condition, storage configuration (16GB, 32GB, 64GB), and seller. While some listings on eBay might show other Redmi models at higher prices, a used Redmi 4X typically fetches a very low amount. As of July 2026, you can expect a functional Redmi 4X to be priced between $15 and $40, reflecting its age and limited utility. Swappa, for instance, often shows trade-in values near $0 due to its obsolescence, further confirming its low market value.
Be wary of listings that seem too good to be true or sellers who overprice the device. Always check seller ratings and insist on clear photos of the device’s condition.
Performance Expectations in 2026
The Redmi 4X’s Snapdragon 435 processor, paired with 2GB or 3GB of RAM, was adequate for casual tasks in 2017. In 2026, however, it struggles significantly with modern applications and multitasking.
You can expect sluggish performance, long app loading times, and frequent stutters, especially with social media apps, modern web browsing, or any application requiring significant processing power. Light applications, such as basic messaging or simple games, might still run, but don’t anticipate a smooth user experience.
The device’s internal storage, often 16GB or 32GB, will also quickly fill up with system files and even a few basic apps, necessitating a microSD card for any significant media storage. The 5-inch HD display, while decent for its time, offers lower resolution and color accuracy compared to even entry-level phones today.
The Critical Security and Software Dilemma
Perhaps the most significant drawback of acquiring a Redmi 4X in 2026 is the complete lack of official software and security updates. The device stopped receiving updates years ago, leaving it vulnerable to newly discovered security exploits.
Running an outdated Android version (likely Android 7.1 Nougat or older) with no security patches means that your personal data could be at risk, especially if you use the device for banking, sensitive communications, or even general web browsing. According to Android’s official security documentation, regular updates are crucial for protecting against malware and data breaches. Using an unpatched device for sensitive tasks is a considerable security risk.
Beyond that, many modern applications in the Google Play Store may no longer support such old Android versions, or they might run very poorly. This limits the app ecosystem significantly, impacting functionality for everyday tasks.
Niche Use Cases: Where the Redmi 4X Might Still Fit
Despite its drawbacks, there are very specific scenarios where buying a Redmi 4X might still make sense, particularly for those on an extreme budget or with unique requirements:
- Emergency Backup Phone: For calls and basic texts in a pinch, it can serve as a disposable spare.
- Dedicated Media Player: If loaded with offline music or videos and kept off Wi-Fi/data, it can be a simple, non-distracting player.
- Child’s First Phone (Highly Supervised): For very young children needing only basic communication with strict parental controls and limited app access, minimizing exposure to online risks.
- IoT Controller: A cheap, dedicated device to control smart home gadgets, kept on a segregated network.
- Car Infotainment (Offline): As a dedicated GPS or music player in an older car, loaded with offline maps and media.
- Learning Device for Modding/Custom ROMs: For tech enthusiasts who want to experiment with custom Android ROMs without risking a primary device.
For any scenario involving internet access or sensitive data, its use should be approached with extreme caution due to security vulnerabilities.
Redmi 4X vs. Modern Ultra-Budget Alternatives
When considering a Redmi 4X to buy, it’s crucial to compare it against even the cheapest new smartphones available in 2026. While the Redmi 4X might cost $15-$40, a new entry-level device from brands like Xiaomi (e.g., a basic Redmi A series model) or Samsung (e.g., a Galaxy A0x) might start from $80-$150. This price difference is significant, but so is the value proposition.

Common Mistakes When Considering an Older Device
The primary mistake people make when looking to buy older smartphones like the Redmi 4X in 2026 is underestimating the impact of obsolescence. Many assume that because it turns on and makes calls, it’s still ‘good enough’ for general use.
Another common error is to prioritize the rock-bottom price over security and functionality. While saving money is always attractive, the trade-offs with a device like the Redmi 4X can lead to frustration or, worse, security compromises that cost more in the long run. For instance, expecting to use it for secure banking or regular social media without issues is unrealistic.
Furthermore, some buyers overlook battery health. A phone from 2017 will almost certainly have a significantly degraded battery, meaning much shorter usage times and a potential need for costly replacement, negating any initial savings. Always inquire about battery health if possible.
Expert Tips for Buying Any Used Smartphone
If you’re still set on buying a Redmi 4X or any older used smartphone, consider these expert insights to mitigate risks:
