The OPPO F33 5G has the larger listed battery and lighter listed weight; the vivo Y400 5G has a slightly larger display, a higher-resolution front-camera specification and higher maximum charging wattage. For the closest memory match, both phones have an 8GB/128GB option, but the cited vivo store listing was ₹31,999 while OPPO’s published F33 8GB/128GB launch price was ₹34,999. That ₹3,000 difference compares a vivo store snapshot with OPPO’s launch price, not two same-time checkout offers.

On the closest RAM/storage match, the OPPO F33 5G 8GB/128GB launch price is ₹3,000 more than the cited vivo Y400 5G 8GB/128GB store price. This is not a same-time checkout-price comparison. OPPO’s 15 April 2026 announcement said F33 sales would begin on 26 April 2026; its figures should not be treated as current discounts or guaranteed live prices. The vivo price applies to the named 8GB/128GB Dynamic Green listing, not every color, storage tier or seller. See the vivo listing and OPPO launch announcement.
Which phone has the better battery and charging?
On capacity, OPPO lists a 7,000mAh typical battery for the F33 5G, compared with 6,000mAh for the vivo Y400 5G. OPPO also states a 6,830mAh rated capacity. vivo lists the higher maximum charging specification: 90W FlashCharge, versus OPPO’s 80W SUPERVOOC.

Display
The vivo’s listed screen is 0.10 inches larger diagonally, at 6.67 inches versus 6.57 inches. It is also listed at 2400 × 1080 pixels; OPPO specifies 2372 × 1080 pixels. Both are AMOLED panels with refresh rates up to 120Hz, though OPPO describes its rate as adaptive. These figures alone do not establish which screen looks better in use.

Cameras
Both phones list a 50MP + 2MP rear-camera setup. vivo lists a 32MP front camera, while the base OPPO F33 5G lists 16MP. Megapixel counts describe sensor resolution, not the quality of photos or video; the cited official material does not establish a controlled camera winner.
Be careful not to confuse the base F33 with the F33 Pro. OPPO’s launch material promotes a 50MP ultra-wide selfie camera for the F33 series, but its own specification table assigns the base F33 5G a 16MP front camera and distinguishes the Pro model’s 50MP ultra-wide front camera.

Processor and storage
vivo lists the Snapdragon 4 Gen 2 (4nm), and OPPO lists the Dimensity 6360 MAX. The available official sources do not provide comparative benchmark results for these exact phones, so the processor names alone are not enough to declare one faster. For storage, both offer an 8GB/128GB configuration; OPPO additionally lists a 6GB/128GB version, while both manufacturers list an 8GB/256GB option.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Weight, protection and software
OPPO lists the F33 at about 189g. vivo lists the Y400 at 197g in Dynamic Green and 198g in Pearl White, making the OPPO lighter on the published figures. vivo lists IP68 and IP69 protection; OPPO’s launch material lists IP66, IP68 and IP69. These are manufacturer-stated protection ratings, not a promise that either phone is damage-proof.
Best Value
- Compatible with Vivo Y400 5G Phone Cases
- The phone case features a matte PU leather exterior with a TPU frame and magnetic plate, offering skin-friendly, slim, and comfortable materials.
- The screen edges and camera frame are fully wrapped with elevated protection to effectively prevent scratches. It withstands minor drops, bumps, and impacts.
- Soft-padded edges provide a comfortable grip and resist deformation. Built-in magnetic plate enables use with car mounts and other accessories.
- Stylish appearance meets precise cutouts, allowing full access to all ports and the camera. Buttons offer soft, responsive tactile feedback for effortless operation.
vivo cautions that underwater photography should be done only in fresh water, no deeper than 2m and for no longer than 30 minutes per use; liquid-immersion damage is not covered by its warranty. Review the manufacturers’ current warranty terms and care instructions rather than treating an IP rating as coverage for water damage.
The official vivo listing names Android 15 with Funtouch OS 15. OPPO’s F33 specification page lists ColorOS 16, and its launch material describes the software as Android-based.
Which one should you choose?
- Consider the OPPO F33 5G if the larger listed battery capacity, lower listed weight or availability of a 6GB/128GB tier matters most to you.
- Consider the vivo Y400 5G if you prefer its larger listed screen, 32MP front-camera specification or higher maximum charging wattage.
- Compare the exact 8GB/128GB prices at checkout if those are the configurations you are considering. The cited ₹3,000 gap is between different price snapshots and may not match current offers.
Neither phone is an evidence-based overall winner from specifications alone: the official sources do not establish comparative day-to-day speed, battery endurance, photo quality or long-term durability.
