| Phone and configuration | Price and basis |
|---|---|
| vivo Y400 5G, 8GB/128GB, Dynamic Green | ₹31,999 on vivo India’s E-Store listing when checked for this comparison. See the listed configuration. |
| OPPO F33 5G, 8GB/128GB | ₹34,999, the launch price published by OPPO on 15 April 2026. See OPPO’s launch announcement. |
On those stated bases, the OPPO 8GB/128GB launch price is ₹3,000 higher. This is not a same-time checkout-price comparison, and OPPO’s published launch price should not be read as a current deal. Its other announced prices were ₹31,999 for 6GB/128GB and ₹37,999 for 8GB/256GB. Check the live listing for the exact storage tier and color before buying; prices and offers can change.
Which phone has the better battery and charging?
OPPO lists the larger typical capacity: 7,000mAh, with a rated capacity of 6,830mAh, compared with vivo’s 6,000mAh typical capacity. vivo, meanwhile, lists the higher maximum charging power: 90W versus OPPO’s 80W. Those figures alone do not show how long either phone lasts between charges or how quickly it charges in actual use; the official specifications cited here do not provide a controlled head-to-head test.

Which phone has the better display and cameras?
Display
vivo lists a 6.67-inch AMOLED screen with 2400 × 1080 resolution; OPPO lists a 6.57-inch AMOLED screen with 2372 × 1080 resolution and an adaptive refresh rate up to 120Hz. The Y400 therefore has the larger stated diagonal, while the F33 specifies an adaptive refresh rate. These specifications do not establish which screen looks better in person.
Front and rear cameras
The Y400’s listed front-camera resolution is 32MP, compared with 16MP on the base F33 5G. OPPO’s launch announcement discusses a 50MP ultra-wide selfie camera in the F33 series, but its specifications distinguish that sensor from the base F33 5G’s 16MP front camera; do not attribute the Pro model’s 50MP camera to the base phone. Both phones list a 50MP + 2MP rear-camera setup. Megapixel counts and camera configurations do not prove which phone takes better photos, and the official sources cited here do not provide a controlled comparison of image quality.

Durability, weight and software
OPPO’s launch material lists IP66, IP68 and IP69 protection for the F33 5G; vivo lists IP68 and IP69 for the Y400 5G. Water-resistance ratings are not a guarantee against damage. vivo specifically says underwater photography should be in fresh water, no deeper than 2m and no longer than 30 minutes per use, and says liquid-immersion damage is not covered by its warranty.
The listed F33 weight is about 189g. The Y400 is listed at 197g in Dynamic Green and 198g in Pearl White. The official listings identify Android 15 with Funtouch OS 15 for vivo and ColorOS 16, Android-based, in OPPO’s launch material.

- Compare the exact RAM and storage tier before deciding on price. The closest published comparison here is 8GB/128GB on both phones, but the prices have different bases and may change.
