The realme P4 5G has the larger display, higher stated refresh rate and larger battery; the vivo Y400 5G has higher rated wired charging, a higher-resolution front camera and advertised IP68/IP69 ratings. Both list a 50MP main rear camera, but their secondary cameras and chipsets differ. There is no dependable single price gap: listings vary by storage variant, seller and stock status, so compare live checkout prices for the same configuration.

Specifications are from the manufacturers’ India product information: vivo Y400 5G and realme P4 5G. A difference in listed specifications does not by itself establish which phone looks smoother, lasts longer, charges faster in practice or takes better photos.
Which phone has the better display?
The P4’s screen is 0.10 inch larger diagonally and its stated maximum refresh rate is 144Hz, compared with 120Hz on the Y400. Both are FHD+ AMOLED displays. Those figures describe the manufacturers’ specifications, not a direct comparison of brightness, color accuracy, outdoor visibility or perceived smoothness. If you are choosing based on the display, check the phones in person when possible and consider size as well as refresh rate.
How do performance and storage compare?
The Y400 uses Qualcomm’s Snapdragon 4 Gen 2, while the P4 uses MediaTek’s Dimensity 7400 Ultra. These chipset names identify different platforms; without a comparable independent benchmark or hands-on test, they are not enough to declare one phone faster for gaming, everyday apps or sustained workloads.

For storage, vivo lists the Y400 with 8GB RAM and either 128GB or 256GB storage. realme lists the P4 in 6GB/128GB, 8GB/128GB and 8GB/256GB configurations. Match both RAM and storage when comparing prices, rather than treating different variants as equivalent.
What do the camera specifications tell you?
Both phones list a 50MP main rear camera. The P4 adds an 8MP wide-angle camera; the Y400’s listed secondary rear camera is 2MP. Their front cameras are listed at 16MP on the P4 and 32MP on the Y400. Megapixel counts and camera-module labels do not establish photo quality. The specifications alone cannot show how the phones handle low light, motion, skin tones, video or image processing.

Capacity and wattage are manufacturer specifications; they do not establish comparative battery life or time to charge under real-world conditions.

How do durability and included accessories compare?
vivo advertises IP68 and IP69 ratings for the Y400. Check the manufacturer’s stated test conditions and warranty terms before exposing a phone to water; an IP rating should not be treated as a promise that every kind of liquid exposure or damage is covered. The official realme P4 product information examined does not state a comparable IP rating, which is not proof that the phone has no protection.
Both manufacturers list useful basics in the box. vivo lists a charger, cable, eject tool, case and applied protective film. realme lists a charger, cable, SIM tool, case and guide. Contents can vary by market or package, so confirm the box contents for the specific listing you buy.

What is the price difference in India?
There is no reliable, like-for-like price gap to quote from the available listings. vivo’s India store showed an 8GB/128GB Y400 at ₹31,999 on one listing and ₹40,999 on another selected listing marked unavailable; a 8GB/256GB listing showed ₹34,999 and was out of stock. Separately, a 91mobiles comparison snapshot showed ₹34,999 for a Y400 Amazon listing and ₹20,999 for a P4 listing marked out of stock. These are listing snapshots, not guaranteed checkout prices, and they do not establish a current difference between matched variants.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A vivo Community post dated August 4, 2025, stated launch prices of ₹21,999 for the Y400 8GB/128GB and ₹23,999 for 8GB/256GB. That community post is not an authoritative current-price listing. Before buying, compare the same RAM/storage configuration at checkout and check seller, stock, exchange conditions and any bank or promotional offer. Prices and availability can change.

- Consider the vivo Y400 5G if you prioritize its advertised IP68/IP69 ratings, 90W rated charging or 32MP front-camera specification.
- Decide on price only after checking live, matched variants. The available snapshots differ in listing, stock state and configuration, so they do not support a definitive claim that one is currently cheaper by a particular amount.
