Vivo T4 Pro 5G vs Vivo Y400 5G: specs, score & best pick

Vivo Y400 5G has the larger verified battery and a higher battery score in the supplied comparison. That makes it the clearer choice if battery capacity is the priority.

• • 7200 mAh vs 6500 mAh
• • Battery score 9.0 vs 8.2

Vivo Y400 5G is cheaper by INR 1,008, which is a difference of a little over 3%. The gap is large enough to matter, but not enough to make the devices similar-priced.

• • INR 28,991 vs INR 29,999
• • Price gap is 3.36%

Vivo T4 Pro 5G has more memory and more built-in storage. That gives it a clear advantage for buyers who keep more apps, files, or media on the phone.

• • 8GB RAM vs 6GB RAM
• • 256GB storage vs 128GB storage

The chipsets and RAM differ, but the deterministic comparison still marks performance as insufficient data. Because of that, no reliable performance winner can be declared from the verified facts alone.

• • Dimensity 7400-Turbo vs 7 Gen 4
• • MediaTek vs Snapdragon
• • 8GB RAM vs 6GB RAM

Vivo Y400 5G is cheaper by INR 1,008, but the deterministic value comparison still marks this category as insufficient data. That means no formal value winner should be declared from the verified facts alone. Price-conscious buyers can still note that Y400 5G has the lower current price.

• • INR 28,991 vs INR 29,999
• • Value comparison marked as insufficient data

Camera comparison is tied on the verified facts. Both phones list a 50MP rear camera and a 32MP front camera, and neither has verified OIS. No extra rear-camera hardware such as telephoto, ultrawide, or periscope is verified for either device, so no camera winner is declared.

• • 50MP rear camera on both phones
• • 32MP front camera on both phones
• • OIS is absent on both
• • No verified telephoto, ultrawide, or periscope on either phone

Vivo Y400 5G is the battery winner. It has the larger 7200 mAh battery and the higher verified battery score, so it is the stronger pick for buyers who care most about battery capacity. Vivo T4 Pro 5G still has a large battery at 6500 mAh, but it trails the Y400 5G here.

• • 7200 mAh vs 6500 mAh
• • Battery score 9.0 vs 8.2

Both phones have 120Hz displays, but the verified panel details are incomplete enough that no display winner can be declared. Vivo Y400 5G is listed with a 6.76-inch AMOLED screen, while Vivo T4 Pro 5G is listed at 6.77 inches with the panel type not verified. The current facts do not provide a strong enough basis to separate them on display quality.

• • 120Hz on both phones
• • Vivo Y400 5G: 6.76-inch AMOLED
• • Vivo T4 Pro 5G: 6.77-inch display, panel type not verified

No software winner can be declared because the verified facts do not include the operating system version or meaningful update-support duration for either phone. That makes long-term support impossible to compare confidently from the available data. Buyers who care about software longevity will need verified update details before making a final call.

• • Operating system details not verified for either phone
• • Update-support duration not verified for either phone

Both phones have different verified chipsets and different RAM configurations, but the comparison context does not provide enough reliable data to rank performance. Vivo T4 Pro 5G lists a Snapdragon 7 Gen 4 with 8GB RAM, while Vivo Y400 5G lists a MediaTek Dimensity 7400-Turbo with 6GB RAM. That is enough to note a hardware difference, but not enough to name a trustworthy speed winner.

• • Vivo T4 Pro 5G: 7 Gen 4, Snapdragon, 8GB RAM
• • Vivo Y400 5G: Dimensity 7400-Turbo, MediaTek, 6GB RAM
• • Performance comparison marked as insufficient data
