The OPPO F33 Pro 5G has the higher listed battery capacity, while the vivo Y400 5G has the larger display and higher maximum charging wattage. OPPO announced India launch prices of ₹37,999 for 8GB+128GB and ₹40,999 for 8GB+256GB on 15 April 2026; those are launch prices, not guaranteed current offers. Which phone is the better fit depends on which specifications matter to you and the live price of the exact configuration.

Which phone has the larger display?
The vivo Y400 5G has the larger listed screen: 6.67 inches versus 6.57 inches on the OPPO F33 Pro 5G. Both are FHD+ class displays with refresh rates up to 120 Hz. OPPO describes its refresh rate as adaptive; the published diagonal and resolution figures alone do not determine which display looks better.

OPPO lists a 7,000 mAh typical battery, compared with 6,000 mAh typical on vivo. That is a higher rated capacity, not proof of longer runtime: no common battery test under matched conditions is established here. Charging ratings go the other way: vivo lists up to 90 W, while OPPO supports up to 80 W SUPERVOOC. Maximum wattage by itself does not establish full-charge time; charger compatibility and the charging curve matter.

How do the cameras compare?
Front cameras
vivo lists a 32 MP front camera. OPPO’s launch announcement specifies a 50 MP ultra-wide front camera with a 100° field of view, a configuration intended to include a wider scene or more people in a selfie. Megapixels and field of view describe different attributes, and neither establishes which phone produces better photos without comparable camera testing.
Rear cameras
The listed rear setups are 50 MP plus 2 MP on vivo and a 50 MP main plus 2 MP portrait camera on OPPO, according to its launch announcement. These specifications do not establish image quality or low-light performance.

What are the India prices?
OPPO India announced these F33 Pro 5G launch prices on 15 April 2026: ₹37,999 for 8GB+128GB and ₹40,999 for 8GB+256GB. The announcement said sales would begin on 23 April 2026 through offline stores, OPPO E-Store, Flipkart and Amazon. Treat these as launch terms, not current prices: retailer stock, offers and listings can change. See the OPPO India announcement.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A 91mobiles comparison page displayed Amazon observations of ₹31,999 for vivo Y400 and ₹39,999 for OPPO F33 Pro when accessed in 2026. These are volatile marketplace observations, not stable list prices; the exact seller, configuration, stock and offer may differ. The available evidence does not establish a durable current transaction price for vivo. Before deciding on price, compare live listings for the same storage configuration and check whether discounts depend on a bank offer or exchange. The vivo India shop listing identifies product configurations but does not establish a stable transaction price.
Rank #3
- Compatible with vivo Y400 5G Phone Case Cover
- Magnetic ring design. Compatible with most wireless magnetic products on the market, such as wireless chargers, magnetic car mounts, magnetic batteries, and magnetic wallets.
- The phone case features a dual-layer TPU+PU construction for a comfortable, non-slip feel. Corner airbags provide drop protection to safeguard your device.
- Perforated design enhances airflow for accelerated heat dissipation. Precise cutouts ensure full functionality of all ports, buttons, and cameras.
- Raised edges around the screen and rear camera elevate these components off the surface, effectively protecting them from scratches.
Do the performance figures show which phone is faster?
Both phones use different processors: Snapdragon 4 Gen 2 in vivo and Dimensity 6360 MAX in OPPO. A 91mobiles comparison page lists AnTuTu scores of 478,134 for vivo Y400 and 651,333 for OPPO F33 Pro. The page’s available figures do not establish matched firmware, benchmark version, temperature or repeatability, so they should not be treated as a controlled head-to-head result or a guarantee of gaming and everyday speed. Real-world performance also depends on software and workload.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What do the durability ratings mean?
vivo lists IP68 and IP69; OPPO’s launch release lists IP69K, IP68 and IP66. These are specific ingress-protection ratings, not blanket promises that a phone is damage-proof. Read the relevant manufacturer conditions and warranty terms before relying on a rating in a particular situation. OPPO’s description of the F series as “India’s Durable Champion” is promotional language from its launch announcement, not independent durability evidence.

Which phone should you choose?
- Choose based on screen size if a larger listed display is your priority: vivo’s diagonal is 6.67 inches, against OPPO’s 6.57 inches.
- Compare battery capacity carefully if you prioritize a higher rated figure: OPPO lists 7,000 mAh typical versus vivo’s 6,000 mAh, but matched runtime testing is not established.
- Consider selfie framing if you often take group selfies: OPPO specifies a 50 MP ultra-wide front camera with a 100° field of view; vivo lists 32 MP. That difference does not establish which camera takes better images.
- Compare current, matching configurations if price is decisive. Use the same storage capacity where possible and verify seller, stock and offer before treating a price gap as meaningful.
- Check manufacturer conditions if water and dust protection matters; do not interpret ratings as a promise against all damage.
