Seven years is a long time in smartphone years, but the Xiaomi Redmi 4X still shows up in shopping carts around the world. If you’re on a tight budget and wondering whether this 2017 workhorse still makes sense in 2025, you’re not alone.
Release Year: 2017 · Battery Capacity: 4100 mAh · Display Size: 5.0 inches · Used Price Range (2025): $50–$120
Quick snapshot
- 5.0-inch IPS LCD display (Wikipedia (community encyclopedia))
- Qualcomm Snapdragon 435 processor (TG Wireless (US refurbished reseller))
- 4100 mAh battery (YouTube tech review)
- Exact stock availability in Nigeria and parts of Africa
- Long-term reliability of refurbished units
- Launched March 2017, discontinued 2018–2019, still sold refurbished in 2025
- No more software updates; security risk grows each year
Six specs, one pattern: the Redmi 4X was built for endurance, not speed.
| Specification | Details |
|---|---|
| Release Date | March 2017 |
| Original Price | $120 (approx) |
| Current Used Price | $50–$80 |
| Battery | 4100 mAh (non-removable) |
| Processor | Qualcomm Snapdragon 435 |
| RAM/Storage | 2GB/16GB, 3GB/32GB, 3GB/64GB |
The implication: the core hardware remains what it was, but software has moved on.
Is the Redmi 4X a good phone?
Overall performance and value
- Processor: The Snapdragon 435 handles basic tasks like calls, messaging, and light browsing without major lag (TG Wireless (US refurbished reseller)).
- Battery: The 4100 mAh battery easily lasts two days on moderate use and up to four days with lighter use, according to a YouTube tech reviewer.
- Value: At its original $120 price, it was a steal. In 2025, a used or refurbished unit costs $50–$80, which is still competitive in the ultra-budget segment (refurbed (certified refurbished marketplace)).
The implication: the Redmi 4X delivers strong battery endurance and acceptable everyday performance for the price, but its Snapdragon 435 will struggle with modern multitasking and heavy apps.
User satisfaction ratings
- Positive feedback: On GSMarena, users consistently praise the battery life and build quality. One anonymous reviewer noted: “Easily lasts two days with moderate use.” (GSMarena (independent phone database))
- Mixed opinions: Camera performance is widely considered average, and the lack of software updates is a recurring complaint.
What this means: if you value battery above all else, the Redmi 4X still satisfies. But don’t expect a smooth experience with 2025 apps.
Battery life is outstanding — up to four days on light use — but you trade away all future software updates and app compatibility.
How is the Xiaomi Redmi 4x according to active users?
Common praise from users
- Battery life: The 4100 mAh battery is the most frequently highlighted feature. Many users report charging every other day (YouTube tech review).
- Build quality: The metal unibody design feels premium for its price bracket (Wikipedia (community encyclopedia)).
- Affordability: Original buyers appreciated the low upfront cost, and refurbished buyers still find it a cheap entry point (Cashify (Indian refurbished marketplace)).
The pattern: long battery life is the single biggest reason people still recommend this phone in 2025.
Frequent complaints and issues
- Performance lag: Users running WhatsApp, YouTube, or social media apps report stutter and slow loading times.
- Camera quality: The 13 MP rear camera and 5 MP front camera are described as “average” and struggle in low light (GSMarena (independent phone database)).
- No software updates: The device shipped with Android 6.0 and was updated only to Android 7.1.2. It now runs outdated security patches (Wikipedia (community encyclopedia)).
The catch: the Redmi 4X is now a legacy device — its software stopped evolving five years ago, leaving it exposed to modern security threats.
How old is the Redmi 4X?
Launch date and timeline
- Announcement: The Redmi 4X was announced on February 14, 2017 (Wikipedia (community encyclopedia)).
- Global release: It launched globally in March 2017.
- Discontinuation: Xiaomi stopped selling it through official channels in 2018–2019 (refurbed (certified refurbished marketplace)).
Why this matters: at seven years old, the Redmi 4X is ancient by smartphone standards. Most Android manufacturers stop security updates after three years.
Impact of age on current usability
- Security risk: No new security patches mean the phone is vulnerable to exploits discovered after 2019.
- App compatibility: Newer apps may refuse to install or run poorly on Android 7.1.
- Hardware degradation: Seven-year-old batteries often hold less charge than new — expect slightly shorter real-world battery life than the original 4100 mAh.
The implication: the Redmi 4X can still function as a secondary phone or a media player, but relying on it as a daily driver carries real security risks.
What is the price of Redmi 4X?
Original launch price
- International: It launched at approximately $120 (Wikipedia (community encyclopedia)).
- India: The Redmi 4 (India version of Redmi 4X) started at ₹6,999.
The contrast: the price has dropped significantly, but the trade-off in software support is steep.
Current market prices (new vs used)
- Refurbished via refurbed: Listed as up to 40% cheaper than new, with free delivery (refurbed (certified refurbished marketplace)).
- Cashify (India): Offers refurbished units with a 6-month warranty and easy EMI (Cashify (Indian refurbished marketplace)).
- Wholesale (Alibaba): A 2025 listing shows refurbished Redmi 4X units priced from ₹2,499 to ₹15,102 (roughly $30–$180) (Alibaba (B2B marketplace, medium confidence)).
- Bulk pricing: A Made-in-China listing offers wholesale refurbished units at US$80 for 1–49 pieces, $75 for 50–999, and $60 for 1,000+ (Made-in-China (wholesale platform)).
The pattern: used prices vary widely — expect to pay $50–$80 for a single unit in good condition, but watch for hidden costs like shipping and lack of warranty.
If you can secure a unit from a trusted refurbisher with a warranty (like Cashify or refurbed), the price is fair. But dirt-cheap listings on marketplaces may hide poor battery health or missing parts.
Where can I buy the Redmi 4X?
Trusted online retailers
- refurbed (Europe): Unlocked refurbished devices with free delivery and up to 40% savings (refurbed (certified refurbished marketplace)).
- Cashify (India): Refurbished units with 6-month warranty and EMI options (Cashify (Indian refurbished marketplace)).
- TG Wireless (US): Factory refurbished GSM unlocked models (TG Wireless (US refurbished reseller)).
- eBay / local classifieds: Used units from individuals — check seller ratings and request battery health info.
What to watch: always confirm the network bands match your carrier. The Redmi 4X supports 4G LTE but not all bands in every region.
Regional availability (Nigeria, India, Europe)
- Nigeria: The Redmi 4X is still sold on local e‑commerce platforms like Jiji and Konga, but stock is inconsistent. Be wary of non‑refurbished units with worn batteries.
- India: Cashify and local electronics stores often carry it. The Indian variant is identical to the Redmi 4 (China) (Wikipedia (community encyclopedia)).
- Europe: refurbed and Back Market offer refurbished units with buyer protection and 30‑day return policies.
The trade-off: buying from a local marketplace may save you $10–$20, but you lose warranty and quality assurance.

“Easily lasts two days with moderate use.”
— GSMarena user review (GSMarena (independent phone database))
“The Redmi 4X is an improved version of the Redmi 4 with better battery and design.”
— Wikipedia (community encyclopedia)
“With moderate use, you can get around two days of heavy use or up to four days of lighter use.”
— YouTube reviewer (YouTube tech review)
The Redmi 4X proves that a great battery can keep a phone relevant long after its software expires. For budget buyers in Nigeria, India, or Europe looking to spend under $80, it still offers a usable smartphone experience — but only if you’re willing to accept zero future updates and declining app compatibility. For cost-conscious shoppers who need a secondary device or a media player, the choice is clear: a refurbished Redmi 4X from a trusted seller like Cashify or refurbed gives you battery longevity and low upfront cost, but you must weigh those savings against the growing security risk of running an unsupported Android handset.
