The new Vivo Y400 5G launched in India on 4 August 2025 at a starting price of ₹21,999 for the 8 GB RAM + 128 GB storage variant. While a “special launch deal” is circulating that claims the model offers 512 GB of storage, 16 GB of RAM and 200 W charging, official specifications show up to 256 GB storage, 8 GB RAM and 90 W charging — meaning consumers must proceed with caution.

Spec-Sheet vs Marketing Claims
Official Indian specifications
According to the company’s Indian product page, the Y400 5G features:
- A 6.67-inch Full HD+ (1080×2400) AMOLED display with 120 Hz refresh rate.
- Qualcomm Snapdragon 4 Gen 2 4nm chipset, up to 8 GB RAM and either 128 GB or 256 GB of UFS 3.1 storage.
- 6,000 mAh battery with support for 90 W wired fast charging.
- Dual rear cameras: 50 MP Sony IMX852 + 2 MP depth sensor; front camera: 32 MP.
- IP68 & IP69 ratings for dust and water resistance.
The “512 GB / 16 GB / 200 W” claim
Promotional statements or launch-deal materials have suggested a variant with 512 GB storage, 16 GB RAM and a 200 W charging capability. If accurate, this would significantly raise the device’s value proposition. However:
- No reputable source lists the Indian model with 16 GB RAM or 512 GB storage as standard.
- Charging spec is consistently cited as 90 W, not 200 W. (See official page)
- Some pre-launch reports referenced the device “up to” 8 GB/256 GB rather than any 16 GB/512 GB option.
Why this matters
The difference between claimed and verified specs matters because storage, RAM and charging speed are key differentiators for buyers. When such features are over-promised, consumer trust becomes vulnerable.

Vivo Y400 5G Key Features & Real-World Implications
What the device offers
Despite the discrepancy, the Y400 5G still offers strong features for its price bracket:
- The 120 Hz AMOLED display and large 6,000 mAh battery give it a competitive edge in user experience and endurance.
- IP68/69 ingress protection is relatively rare in this price segment in India.
- The 50 MP main camera and 32 MP selfie unit deliver solid results in good lighting, according to initial reviews.
Areas of limitation
- The camera lacks an ultrawide lens, which competitors may include at similar prices.
- The 8 GB RAM/256 GB storage ceiling may limit power users compared with the advertised 16/512 claim.
- Charging at 90 W, albeit fast, is not the “ultra-fast” 200 W some marketing implies — meaning real-world top-ups will be slower than expect in the higher tier claimed variant.
Competitive context
In India’s ~₹20,000-₹25,000 range, the Y400 5G positions well. Competitors might offer faster charging or more cameras but possibly sacrifice things like IP ratings or screen refresh. A balanced view: the Y400 5G is a strong mid-segment option, albeit not perfect.
Consumer Guidance & Purchase Checklist
What buyers should verify
- Confirm storage and RAM: Ensure you’re buying the required variant (128/256 GB rather than 512 GB).
- Check charger and charging speed: The box should list 90 W or indicate “supports up to”. If a 200 W charger is included, verify authenticity.
- Look for warranty and service support: When buying online or from third-party sellers, check terms for India.
- Test real-world performance: Updates, software behaviour, battery endurance and charging times matter more than advertising claims.
- Check whether offers (e.g., special launch deal) come with conditions — e.g., bank discounts, exchange offers or lesser specs.
Why hold off or buy now?
If you value a balanced feature set (display, battery, IP rating) and can accept 8 GB RAM/256 GB storage + 90 W charging, this phone is worth considering now. If you expect 16 GB RAM, 512 GB storage and 200 W charging — then monitor for an official variant update or wait for reviews confirming such a version.

Why the Spec Discrepancy Might Have Emerged
Regional variant or future upgrade possibility
It is possible that a 16 GB/512 GB/200 W variant exists in other markets (e.g., China) or will launch at a later stage in India. Leaks suggested such possibilities. (Indiatimes)
Marketing nuance and limited availability
Marketing materials describing “up to” certain specs can be interpreted as inclusive of future or overseas variants. Consumers should read fine print. Additionally, “special launch deal” may bundle extra storage via software/virtual memory or emphasise temporary discount offers rather than permanent spec upgrades.
The Vivo Y400 5G is a compelling mid-range 5G smartphone in India, offering strong value through its large battery, 120 Hz AMOLED display and IP68/69 rating. However, the widely circulated claims of a 512 GB storage variant with 16 GB RAM and 200 W charging do not align with currently verified Indian specifications, which list up to 256 GB storage, 8 GB RAM and 90 W charging.
Buyers are advised to verify the exact variant, charging accessories and pricing before purchase — and to rely on official spec sheets and independent reviews rather than promotional hype.
