Redmi 4X to Buy: Price, Specs, Pros & Cons (2025 Guide)

Some phones fade into obscurity after a few years, but the Redmi 4X still pops up in conversations and second‑hand listings long after its 2017 launch. With a 4100 mAh battery and Snapdragon 435 chip, this Xiaomi budget phone was a hit – eight years later, the real question is whether it still makes sense to buy one.

Release year: 2017 · Original price: ~$150 · Battery capacity: 4100 mAh · Display size: 5.0 inches · RAM / Storage: 3 GB / 32 GB

Here are the full specifications for the Redmi 4X as confirmed by multiple sources.

How old is the Redmi 4X?

When was the Redmi 4X released?

The Redmi 4X was officially announced on 2017‑02‑14, according to Wikipedia (user‑edited encyclopedia). Sales began in March 2017 across China, as recorded by PhoneArena (specs and review hub).

What is the current age of the Redmi 4X?

As of 2025, the Redmi 4X is approximately eight years old. That puts it in the “vintage” category for smartphones, long past the typical two‑ to three‑year update window for most manufacturers. The implication: you are buying a device that stopped receiving major software updates around 2020 (FoneArena (specs database)).

The pattern: this phone has crossed from supported to legacy status, making it a risky choice for anyone who relies on app compatibility.

Is the Mi 4X a good phone?

Key features of the Redmi 4X

• 5.0‑inch 720×1280 IPS display (PhoneBunch)
• Qualcomm Snapdragon 435 chipset, Adreno 505 GPU (same source)
• 13 MP rear camera, 5 MP front camera (same source)
• 4100 mAh battery (Wikipedia)
• Android 6.0.1 (Marshmallow) at launch, later updated to Android 7.1.2 via MIUI 11 (same Wikipedia source)

Performance for daily tasks

For basic usage – messaging, calls, social media, light browsing – the Snapdragon 435 still holds up. YouTube playback at 720p is smooth. However, demanding apps and multitasking with multiple tabs will show its age. The 3 GB RAM configuration is usable but far from snappy by 2025 standards (PhoneArena).

Comparison with 2017 competitors

Against rivals like the Moto G5 and the Samsung Galaxy J5, the Redmi 4X excelled in battery life and build quality. Its 4100 mAh cell was significantly larger than the typical 3000 mAh found in similar‑priced phones that year. The trade‑off: the 5‑inch 720p display was sharp enough for its time but is now outclassed by even entry‑level 1080p panels.

The implication: the Redmi 4X is best seen as a secondary device, not a primary workhorse.

What was the original price of a Redmi 4X?

Launch price

At its Chinese launch, Xiaomi priced the Redmi 4X at 699 Yuan (≈$100) for the 2 GB/16 GB variant and 899 Yuan (≈$130) for the 3 GB/32 GB variant, as reported by Gizmochina (tech news outlet). Outside China, the 3 GB model typically sold for about $120–$150.

Price drop over time

Today, second‑hand and refurbished units are available for €50–€80 (≈$55–$90) on platforms like Back Market and eBay. Used units without warranty can dip as low as €30–€50. The pattern: depreciation has flattened – the phone won’t get much cheaper, but it also isn’t appreciating.

What this means: the phone has reached its floor price, so it’s a safe buy if you accept the trade‑offs.

What is the weakness of Redmi?

Weaknesses of the Redmi 4X specifically

• Outdated software: Originally Android 6.0.1; official updates ended with MIUI 11 based on Android 7.1.2 (Wikipedia (user‑edited encyclopedia)). No security patches since 2020.
• No NFC: Lacks support for contactless payments (FoneArena (specs database)).
• Average camera: The 13 MP rear sensor performs poorly in low light (PhoneBunch).
• No fingerprint sensor on some models: Later batches included one, but the early units relied on pattern/PIN (Gizmochina).

General Redmi weak points

Xiaomi’s Redmi line has historically cut corners on camera sensors, software update frequency, and included accessories (no charger in some regions). The Redmi 4X exemplifies these trade‑offs: a large battery and solid build, but at the expense of the camera and software longevity.

The pattern: Redmi trades longevity for price, and this model shows that trade‑off clearly.

What is the cheapest price of Redmi?

Current cheapest Redmi 4X prices

As of early 2025, the lowest prices for a Redmi 4X in working condition are:

• Refurbished (grade B): €50–€80 on Back Market, refurbed
• Used (fair condition): €30–€50 on eBay, adverts.ie
• New‑old‑stock (very rare): €100+ on Amazon (Gizmochina)

Where to find the best deals

Marketplaces like Back Market and refurbed offer buyer protection and a warranty. eBay and local classifieds may be cheaper but carry higher risk of counterfeit or damaged units. Always check seller ratings and ask about battery health. The trade‑off: a protected purchase costs about 20% more than a private sale.

The catch: the warranty cushion is worth the extra cost for a device this old.

Timeline: Redmi 4X history

• May 2017 – Redmi 4X launched in China (Wikipedia (user‑edited encyclopedia))
• 2018 – Received MIUI 9 update (Wikipedia)
• 2019 – MIUI 10 update (Wikipedia)
• 2020 – End of major software updates (Wikipedia)
• 2025 – Still available on secondary market (Gizmochina)

What this means: the timeline confirms that the phone is now a relic, but still functional for limited use.

Clarity: what we know vs. what remains uncertain

Confirmed facts

• Redmi 4X was released in 2017 (Wikipedia)
• Has 4100 mAh battery (same source)
• Snapdragon 435 processor (PhoneBunch)
• 5‑inch 720p display (same source)
• 3 GB RAM / 32 GB storage variant existed (same source)

What’s unclear

• Whether it still receives any security patches (likely not)
• Current availability of brand‑new, unopened units
• Exact number of units still in daily use

The takeaway: the known hardware is reliable, but the software future is a black box.

What people are saying about the Redmi 4X

“Over 11 hours of screen on time is impressive for a budget phone.”

– YouTube reviewer (Redmi 4X Review After 1 Month)

“An octa‑core chip and a large battery at a super cheap price.”

– Xiaomi (via Gizmochina (tech news outlet))

The pattern: early reviewers loved the battery, and that remains the phone’s main draw.

Summary: should you buy a Redmi 4X in 2025?

The Redmi 4X is a capable backup phone or a very budget daily driver if security is not your primary concern. Its battery life remains its standout feature, and the price is hard to beat. But the lack of software support and mediocre camera mean it cannot compete with modern entry‑level phones like the Moto G14 or the Redmi 12C, both of which offer better performance and longer updates for only €100–€130. For a buyer in the New Zealand market looking to spend under NZ$80, the Redmi 4X is a safe second‑hand gamble – provided you buy from a reputable refurbisher. For anyone needing a reliable primary phone, the choice is clear: spend a little more on a newer model, or accept the trade‑offs of a vintage device.
