Which phone has the better screen and form factor?
OPPO F31 5G: bigger display
The F31’s listed 16.69cm display is larger, making it the more obvious option if screen size matters more than one-handed handling. Its listed resolution is lower than the vivo’s, though both support refresh rates up to 120Hz.

vivo X300 FE: compact, higher-resolution panel
The X300 FE combines a 6.31-inch AMOLED panel with a higher listed resolution of 2640 × 1216. Its body dimensions are smaller in height and width than the F31’s, which may suit shoppers who prefer a compact phone. The listed weight is 191g versus about 185g for the F31; measurement conventions may differ.
Which has the stronger performance and storage setup?
On paper, these phones occupy different processor tiers: the F31 lists a MediaTek Dimensity 6300, while vivo lists a Snapdragon 8 Gen 5 built on a 3nm process. That specification difference does not establish a particular real-world speed, gaming, heat or battery advantage; those outcomes require comparable independent testing.
Rank #2
- Compatible with Oppo F31 5G / Compatible with Oppo A6 Pro 4G / Compatible with Oppo A6 Pro 5G
- Magnetic ring design supports magnetic car mounts and is compatible with MagSafe accessories.
- Premium-style high-quality synthetic leather offers a more comfortable feel. TPU + rigid PC construction: enhances durability and improves grip. Soft TPU bumpers facilitate easy installation and removal.

- Precise charging cutouts fit volume buttons, side buttons, and device curves for easy access to all buttons, controls, and ports without removing the case.
The F31 offers 8GB RAM with either 128GB or 256GB storage and supports a storage card. vivo lists 8GB/256GB and 12GB/512GB configurations and UFS 4.1 storage, but no expandable ROM. Check that the configuration you want is actually offered in your region: the vivo store’s displayed 12GB/256GB selection does not match the two configurations listed on its product specification page.

Which phone is better for cameras?
The vivo X300 FE has the clearer camera hardware advantage on the specifications available: in addition to its 50MP OIS main camera, it lists a 50MP OIS telephoto camera and an 8MP wide-angle camera. vivo also says its ZEISS Telephoto Extender Gen 2 is compatible with the X300 FE and must be purchased separately; accessory availability may vary.
Rank #3
- Compatible with Oppo F31 Pro 5G Phone Case Cover

Do not infer image quality from megapixel counts or stabilization alone. The available specifications do not establish how the phones compare in detail, low light, video or portrait results. Also keep the OPPO model suffixes straight: the F31, F31 Pro and F31 Pro+ are separate devices, so Pro-series camera claims should not be assigned to the base F31.
Which has the bigger battery, and which charges faster?
OPPO lists the larger battery capacity: 7000mAh typical and 6830mAh rated, versus vivo’s 6500mAh typical and 6350mAh minimum rated. vivo lists the higher wired charging wattage at 90W, compared with up to 80W SUPERVOOC for the F31. Capacity and maximum wattage are specifications, not measured endurance or charging-time results; actual outcomes depend on usage and charging conditions.
