Realme just did something most phone brands avoid doing on purpose: it launched a cheaper version of an existing phone with a bigger battery than the pricier original.
The Realme P4x 4G went official this week, arriving roughly six months after the original 5G Realme P4x debuted in December 2025. The new variant strips out 5G connectivity to hit a lower price, and in exchange, hands buyers a larger 8,000mAh battery, up from the 7,000mAh cell in the 5G model.
In our analysis, this is a genuinely useful case study in how budget phone brands are increasingly using connectivity as the lever for price segmentation, rather than treating it as a fixed, non-negotiable feature. Understanding exactly what changed between these two models tells you a lot about where that strategy is heading.
What’s Actually Different From the 5G Original
The Realme P4x 4G isn’t simply the existing P4x with the 5G modem removed. Several other components changed alongside that swap.
Here’s the full confirmed spec sheet for the new 4G model:
- 6.8-inch LCD display, HD+ resolution, 120Hz refresh rate, with a waterdrop notch instead of the 5G model’s hole-punch cutout
- Unisoc T7250 octa-core processor
- 4GB of LPDDR4X RAM
- 64GB or 256GB of eMMC 5.1 storage, with a dedicated microSD card slot for further expansion
- 8,000mAh battery with 45W fast charging
- 50MP rear camera with autofocus, 5MP front-facing camera
- Side-mounted fingerprint scanner, 3.5mm headphone jack, USB Type-C port
- IP64 rating for dust and water resistance
- Dual-SIM support, Wi-Fi 5, Bluetooth 5.2, GPS
- 8.78mm thickness, 219 grams
- Available in Phantom Navy and Rally White, with a redesigned rear panel featuring an “AI Pulse” light
Pricing at launch: MYR 799, roughly $195, for the 4GB RAM and 256GB storage configuration.
When looking closely at the data, the chipset swap is the most consequential change here, more than the battery upgrade headlines suggest. The original 5G P4x ran on MediaTek’s Dimensity 7400 Ultra, a genuinely capable mid-range processor. The 4G variant moves to a Unisoc T7250, a considerably more basic chipset built for light, everyday use rather than demanding performance.
The Battery Upgrade Is Real, But Context Matters
An 8,000mAh battery is a genuinely large capacity, even within a market segment where oversized batteries have become an increasingly common selling point through 2026. It’s a meaningful jump from the already-substantial 7,000mAh unit in the 5G model.
A few things worth understanding about why this upgrade happened here specifically:
- Dropping 5G connectivity frees up internal space and reduces power demands from the modem itself, which gives manufacturers more room to fit a larger cell without growing the phone dramatically
- The 4G model retains the same 45W fast charging speed as its 5G sibling, meaning the larger battery doesn’t come with a meaningfully longer charging time in exchange
- This pattern, larger batteries paired with 4G-only variants, has shown up elsewhere in Realme’s recent lineup, suggesting it’s a deliberate strategy rather than a one-off decision for this specific model
That last point is worth sitting with. Realme has been using this same trade-off, dropping 5G to fund a bigger battery at a lower price, across multiple devices recently, which suggests the company has identified a real segment of buyers who value all-day battery life over network speed they may not consistently have access to or need anyway.
The Honest Trade-Offs Buyers Should Weigh
A balanced read of this phone has to be direct about where the cost savings actually came from, because the changes go beyond just the missing 5G radio.
Where the 4G model gives something up compared to its 5G sibling:
- No 5G connectivity at all, which matters significantly for buyers in markets where 5G networks are already widely available and useful
- A notably less powerful processor; the Unisoc T7250 is built for basic daily tasks, not the kind of performance the Dimensity 7400 Ultra offered in the original model
- eMMC 5.1 storage rather than the faster UFS storage standards increasingly common even in budget phones, a detail some early reader reactions to this launch have specifically flagged as a disappointing inclusion in 2026
- A lower-resolution HD+ display compared to the Full HD+ panel on the 5G version
- Only 4GB of RAM, which several early reactions to this launch noted as tight even by current budget-phone standards
That eMMC storage detail deserves a bit more explanation for readers less familiar with the distinction. eMMC storage is genuinely slower than the UFS standard that’s become common even in many budget phones, affecting things like app load times and file transfer speeds. It’s a real, noticeable difference in day-to-day use, not just a number on a spec sheet that only matters in benchmarks.
Why This Strategy Makes Sense for Realme
From a journalistic viewpoint, splitting a phone family into 5G and 4G variants, with deliberately different internals rather than just a simple connectivity toggle, reflects a fairly savvy reading of how budget phone buyers actually make purchasing decisions.
Many buyers in this price segment are choosing based on a small number of headline specs, battery life chief among them, rather than benchmarking processors or comparing storage standards in detail. Leading with a bigger battery number, at a lower price, is a genuinely effective way to capture that specific buyer’s attention.
Worth treating as reasonable industry context rather than overclaiming:
- This isn’t a strategy unique to Realme; budget-focused 4G variants of 5G phones have become an increasingly common approach across several Chinese smartphone brands competing in price-sensitive markets through 2025 and 2026
- Whether buyers fully understand the processor and storage trade-offs that come bundled with the connectivity downgrade is a genuinely open question, since marketing for these phones tends to foreground the battery upgrade much more prominently than the chipset change
- The strategy works best specifically in markets where 4G coverage remains dominant or where 5G adoption hasn’t reached the point where its absence feels like a meaningful daily limitation
Specialist’s Insight: Who Should Actually Choose the 4G Model
This is a phone built for a specific, identifiable buyer, and it’s worth being honest about who that actually is rather than assuming the bigger battery number alone makes it the better choice for everyone.
Genuinely sensible fit for the 4G variant:
- Buyers in markets where 5G coverage is still limited or inconsistent, where the connectivity difference wouldn’t be felt day-to-day anyway
- Anyone whose primary phone use is calls, messaging, social media, and casual browsing, where the Unisoc T7250’s more modest performance won’t create a noticeable bottleneck
- Buyers specifically prioritizing maximum battery life above nearly every other consideration
Better off considering the original 5G model instead, cost permitting:
- Anyone in a market with strong, widely available 5G coverage who would actually benefit from the faster connectivity
- Buyers who care about storage speed, since the jump from eMMC to UFS storage is a genuinely noticeable everyday difference
- Anyone planning even moderately demanding mobile gaming, where the Dimensity 7400 Ultra in the 5G model offers a meaningfully better experience than the Unisoc T7250
For the right buyer, the Realme P4x 4G is a coherent, sensible product, not a confused downgrade. The trade-offs are real, but they’re also consistent and predictable: less processing power and slower storage, in exchange for a lower price and meaningfully more battery capacity. Just go in understanding that trade clearly, rather than assuming the bigger battery number means this is simply a better phone than the model it’s based on.
