What the differences mean in everyday use
Screen size versus display detail
The Y31 5G has the larger 6.68-inch screen, which may suit people who prefer more viewing area. The X300 FE’s 6.31-inch panel is smaller but has a substantially higher listed resolution and uses AMOLED rather than LCD. Choose based on whether you value a larger display or a compact phone with a higher-resolution screen; the specifications alone do not establish which looks better to you.
Storage flexibility
The Y31 5G lists microSD support up to 2TB through a hybrid SIM tray, so using a memory card may affect how you use the second SIM slot. The X300 FE does not list expandable storage, so select enough built-in capacity when purchasing.
Rank #2
- 6.3” HD+ Infinity Display with Curved Glass Design
- A.I Powered Dual Main 13MP+Depth Sensor with LED flash and 13MP Selfie
- 64GB Internal Memory, 3GB RAM. Micro SD up to 64GB; Octa-Core 1.6GHz Processor with ARM Cortex-A55 Chipset
- Super 4,000mAh Battery with Quick Charge, Fingerprint Sensor, and Android 9 Pie
- 4G LTE (1/3/4/5/7/28) 3G: (850/1900/2100)
Camera hardware
The X300 FE lists separate main, telephoto, and wide rear cameras, while the Y31 5G lists a 50MP main camera and a 0.08MP secondary camera. That gives the X300 FE more explicitly specialized rear-camera hardware, but megapixel counts and camera types do not prove better photos. No direct comparative image testing is established here. Its front camera is listed at 50MP with autofocus, compared with 8MP on the Y31 5G; those specifications likewise do not guarantee portrait or low-light results.

Battery and charging
Both India pages list a 6,500mAh typical battery. The Y31 5G lists 44W charging; vivo says its standard charger is supplied. The X300 FE lists up to 90W FlashCharge when used with the original charger and cable. These figures do not establish actual endurance or charging duration. Y31 5G charger and charging specification
Rank #3
- This refurbished product is tested and certified to look and work like new. The refurbishing process includes functionality testing, basic cleaning, inspection, and repackaging. The product ships with all relevant accessories, and may arrive in a generic box
Size and protection
By vivo’s dimensions, the X300 FE is shorter, narrower, thinner, and 18g lighter than the Y31 5G. Both models list IP68 and IP69 ratings. These ratings do not make either phone waterproof; follow the model-specific exposure cautions and warranty terms.
Which one should you choose?
- Choose the Y31 5G if the lower listed price, a larger screen, or microSD expansion matters most. Its listed display is HD+ LCD, and its front camera is 8MP.
- Choose the X300 FE if you want a smaller, high-resolution AMOLED screen, higher-tier listed chipset, more base memory and storage, or dedicated telephoto and wide rear cameras—and the higher price fits your budget.
- Check another option if expandable storage is essential but you need the X300 FE’s other features: the X300 FE page does not list expandable ROM, while the Y31 5G provides microSD support.
X300 FE telephoto extender and regional differences
vivo says its ZEISS Telephoto Extender Gen 2 is compatible with the X300 FE and must be purchased separately. Check local availability and the full cost if you plan to use it. vivo X300 FE telephoto extender information
