Vivo’s latest budget 5G phone brings AMOLED display, massive 6000mAh battery and 90W charging at ₹21,999. A solid pick for battery-focused buyers.

Key Specs (at a glance)

What’s new vs Vivo Y300 5G

• Bigger battery — jumps from 5000mAh to 6000mAh for better all-day usage.
• Faster charging — 90W versus 44W means quicker top-ups during busy days.
• Enhanced durability — adds IP69 rating alongside IP68 for high-pressure water resistance.

Real-world takeaways

Display & Design

The Y400 5G sports a 6.67-inch AMOLED panel with 120Hz refresh rate and 1800 nits peak brightness. This means smooth scrolling and clear outdoor visibility. The phone measures 7.9mm thick and weighs 197g, making it reasonably portable despite the large battery. Build quality uses glass front with plastic back and frame, keeping costs manageable while offering IP68 and IP69 water resistance.

Performance & Thermals

Powered by Snapdragon 4 Gen 2 on 4nm process, the Y400 5G targets everyday tasks rather than gaming. The chipset pairs 2×2.2GHz Cortex-A78 cores with 6×1.95GHz Cortex-A55 cores. While not flagship-fast, it handles social media, messaging and light gaming adequately. The 8GB RAM gets virtual RAM expansion for better multitasking.

Cameras (photo + video)

The main 50MP sensor uses f/1.8 aperture with PDAF for quick focusing. A 2MP depth sensor assists with portrait shots. Both rear and front cameras support 1080p video at 30fps. Vivo includes Ring-LED flash and HDR modes. While not revolutionary, the setup covers basic photography needs for this price segment.

Battery & Charging

The standout feature remains the 6000mAh battery with 90W fast charging. Vivo claims 50% charge in just 20 minutes. Real-world usage should easily deliver full-day battery life, possibly stretching to two days for lighter users. The phone also supports reverse wired charging and bypass charging to reduce heat during gaming sessions.

Software & Updates

Ships with Android 15 and Funtouch 15 out of the box. Vivo includes Circle to Search functionality. The update policy and bloatware situation remain unclear from current information, which buyers should verify before purchase.

• Starting at ₹21,999 for 8GB+128GB variant
• ₹23,999 for 8GB+256GB model

Should you upgrade?

• From a 2-year-old phone — solid upgrade with modern 5G connectivity, AMOLED display and fast charging.
• Budget-focused buyers — competitive option at this price, though consider Realme or Redmi alternatives for better gaming performance.
