The iQOO 15 Ultra appears better suited on paper to buyers prioritizing a high-refresh display and larger battery, while the vivo X300 Pro is the more clearly documented camera-focused option, led by its 200MP ZEISS APO telephoto camera. There is no reliable like-for-like price difference in the cited India listings: the vivo is listed at ₹119,999, while the iQOO is marked not released in India with no store price shown. The iQOO specifications below are third-party listings, not independently confirmed here by an official iQOO source.
How the listed specifications compare
The iQOO figures come from 91mobiles; vivo’s India product page supplies the X300 Pro camera, battery, charging, and refresh-rate specifications. The display size and resolution for vivo below are from 91mobiles, not the vivo product page.
| Specification | iQOO 15 Ultra | vivo X300 Pro |
|---|---|---|
| Display | 6.85-inch QHD+ LTPO AMOLED; 144Hz (91mobiles) | 8T LTPO; 120Hz (vivo India); 6.78 inches and 1260 × 2800 pixels (91mobiles) |
| Rear cameras | 50MP main, 50MP telephoto, and 50MP ultra-wide (91mobiles) | 200MP ZEISS APO telephoto, 50MP main, and 50MP ultra-wide (vivo India) |
| Front camera | 50MP (vivo India) | |
| Battery | 7400mAh (91mobiles) | 6510mAh typical (vivo India) |
| Charging | 100W (91mobiles) | 90W wired FlashCharge and 40W wireless FlashCharge (vivo India) |
| Storage listing | 256GB (91mobiles) | |
| India availability and listed price | Marked “Not Released in India”; no available store price shown (91mobiles) | ₹119,999 at Amazon India in the 91mobiles listing; checkout price and stock can change |
Which phone suits your priorities?
Choose based on display and battery figures
The iQOO’s reported 144Hz refresh rate and 7400mAh capacity are higher than the X300 Pro’s listed 120Hz and vivo’s 6510mAh typical capacity. Those specifications may matter if you value a faster listed refresh rate or a larger stated battery. They do not establish which phone lasts longer in everyday use, charges faster in practice, or looks better: those outcomes depend on testing and usage conditions not established by these specifications.

The X300 Pro has the stronger documented telephoto specification in this comparison: vivo lists a 200MP ZEISS APO telephoto camera, alongside 50MP main and ultra-wide rear cameras and a 50MP front camera. The iQOO’s three listed rear cameras are each 50MP, according to 91mobiles. Megapixel counts alone do not demonstrate image quality, so treat this as a feature comparison rather than a camera test verdict.

vivo describes a Professional Imaging Kit designed for the X300 Pro. A vivo Pakistan announcement also names a vivo ZEISS 2.35x Telephoto Extender. Before choosing either accessory, check that the exact item is compatible with the phone variant sold in your region and confirm local contents, availability, and price.
What the prices do—and do not—show
For India, 91mobiles lists the vivo X300 Pro at ₹119,999 at Amazon India and marks the iQOO 15 Ultra as not released there, with no store price available. That is not a like-for-like price comparison, so the listing does not establish a rupee price gap or which phone is better value. Check current local availability and checkout prices before deciding.

For Pakistan, vivo’s official announcement records a PKR 349,999 launch price for the X300 Pro and says preorders began January 31, 2026. This is a historical Pakistan-market launch detail, not a current price or a comparison with the iQOO.

What to verify before buying
- Check current local availability, retail price, warranty, and the exact storage configuration for both models.
- Treat the iQOO 15 Ultra specifications here as 91mobiles listings; the sources cited here do not establish official iQOO specifications or regional launch details.
- For camera decisions, look for comparable real-world photo and video samples, particularly for telephoto performance, rather than relying on megapixel counts alone.
- Confirm accessory compatibility and regional availability directly for the X300 Pro version you intend to buy.
