On vivo’s own India specification pages, the vivo X300 FE lists the larger battery, faster wired charging, and newer software. The vivo V40 Pro lists the bigger screen and a lower price for its 12GB+512GB configuration. The price gap between the two is not like-for-like, because the configurations differ in storage. The figures below are what vivo lists on its India specification pages and store listings checked in 2026. They are not measured performance results.

Screen size and display

The clearest physical difference is screen size. The V40 Pro’s listed 6.78-inch display is about 0.47 inches larger than the X300 FE’s 6.31-inch panel. Both are AMOLED panels with a 120Hz refresh rate. The V40 Pro’s listed resolution is 2800 × 1260, and the X300 FE’s is 2640 × 1216. If you prefer a larger screen, the V40 Pro is the phone in this pair that offers it. If you want a smaller handset, the X300 FE is the one to consider.

Chipset and software

vivo V40 Pro

The V40 Pro’s specification page lists a MediaTek Dimensity 9200+ chipset and Funtouch OS 14 on Android 14.

vivo X300 FE

The X300 FE’s specification page lists a Snapdragon 8 Gen 5 chipset and OriginOS 6 on Android 16.

The names of the chipsets and the Android versions show which software base each phone starts from. They do not show how fast either phone will feel in daily use. Neither specification page states how long each phone will receive software updates, so that question cannot be answered from these listings.

Cameras

Telephoto 50MP, 2x optical zoom 50MP with OIS, 3x optical zoom
Front 50MP autofocus 50MP autofocus

The two phones trade off in opposite directions. The V40 Pro lists a higher-resolution wide lens, while the X300 FE lists a longer optical zoom with stabilization on its telephoto lens. Megapixel counts do not decide photo quality, because sensor size, lens design, and image processing all matter. The specification pages do not provide enough information to pick a camera winner.

Battery and charging

Item vivo V40 Pro vivo X300 FE
Typical battery capacity 5500mAh 6500mAh
Rated minimum capacity Not stated 6350mAh
Wired charging 80W 90W with original vivo charger and cable, according to vivo

On paper, the X300 FE has about 1,000mAh more typical capacity and a higher listed charging wattage. These are capacity and wattage ratings from vivo’s specification pages. They are not measured battery-life results or charging times.

Price difference: what the listings show

Model Configuration Listed price (vivo India store, 2026)
vivo V40 Pro 12GB+512GB ₹60,999
vivo V40 Pro Other configurations Not stated
vivo X300 FE 8GB+256GB ₹84,999
vivo X300 FE 12GB+256GB ₹89,999

The ₹29,000 gap is the difference between the V40 Pro 12GB+512GB at ₹60,999 and the X300 FE 12GB+256GB at ₹89,999. That comparison mixes two different storage tiers, so it overstates how much more the X300 FE costs for the same storage. The V40 Pro listing with 256GB of storage was not found in the checked store pages, so a same-storage price comparison between the two phones is not available here.

  • Its design with micro dots on the inside prevents the wet and sticky appearance, so common among transparent cases, thus helping to maintain the beautiful design for Vivo V40 5G
  • The matte side strips of the edge can increase the stability of the grip of the mobile phone, making it comfortable to hold and preventing it from slipping, while also preventing phone corrosion from hand sweat. Easy to clean, you only need to gently wipe it with a damp cloth to remove stains and dirt.
  • DIY customization: due to the special material of the transparent phone case, you can stick photos, patterns, etc. that you like on the back of the phone to personalize it and reflect your style and personality.

The only like-for-like pair in the listings is within the X300 FE: the 8GB+256GB model at ₹84,999 and the 12GB+256GB model at ₹89,999. That is a ₹5,000 difference for 4GB of additional RAM on the same storage tier. Prices shift with offers and stock, so check the current listing before deciding.

Optional accessory for the X300 FE

vivo states that its ZEISS Telephoto Extender Gen 2 is compatible with the X300 FE and must be bought separately. It is not included in the phone’s listed price. Confirm the accessory’s availability and compatibility on the vivo India X300 FE overview before buying one. The V40 Pro has no equivalent accessory listed in the sources used for this comparison.

Which phone fits which priorities

On the listed specifications alone, the X300 FE has the stronger sheet for battery, charging, chipset generation and Android version. The V40 Pro offers a larger screen and a 512GB storage option at its listed price.

  • Choose the V40 Pro if you want a 6.78-inch screen, 512GB of storage, or a lower listed entry price.
  • Choose the X300 FE if you want the larger listed battery, 90W wired charging, Android 16 software, or a 3x optical telephoto lens.
  • Consider the X300 FE’s 12GB model only if the extra RAM matters to you, since it costs ₹5,000 more than the 8GB model at listed prices.
  • Consider storage first: if you need 512GB, the V40 Pro is the only one of the two with that configuration in the listings checked.

What these listed figures do not establish

  • Real-world photo and video quality, including low-light results and colour accuracy.
  • Battery endurance, actual charging times, and heat under sustained gaming or video use.
  • Speed differences between the two chipsets in everyday tasks.
  • Software update duration for either model.
  • Current prices, which vary with offers, stock and retailer.

For these points, look for independent reviews that publish measured results, and compare them against the figures above.
