The iQOO 12 5G is the larger-screen option, while the vivo X300 FE is more compact and lists a larger battery plus wireless charging. Their camera hardware also differs: the iQOO has a higher-resolution ultrawide camera on paper, and the vivo pairs a 50MP main camera with a 50MP OIS telephoto. There is no reliable matched current price in the available listings, so a precise price difference cannot be stated.
iQOO 12 5G vs vivo X300 FE specifications
The figures below combine vivo’s official India specifications with third-party iQOO 12 listings. They are manufacturer or listing claims, not independent measurements of battery life, image quality, or performance.

The vivo display brightness figure is a local peak claim; the available information does not establish matching test conditions for a direct brightness comparison. The vivo specification page says maximum supported charging power assumes the original charger and cable, and that actual charging power varies with usage.
Which phone is better for screen size and handling?
Choose the iQOO 12 if a larger viewing area is your priority: its listed display measures 6.78 inches, compared with the X300 FE’s 6.31 inches. The vivo’s official dimensions and 191 g listed weight indicate a shorter, narrower handset, which may suit one-handed use or smaller pockets better. Screen size and listed dimensions do not by themselves establish comfort, since grip and personal preference matter.

Which phone has the better camera?
There is no evidence here for a universal image-quality winner. The more useful distinction is the camera hardware and zoom approach each phone lists.
iQOO 12: more ultrawide resolution on paper
The comparison listing gives the iQOO 12 a 50MP ultrawide camera and a 64MP periscope telephoto, alongside a 50MP main camera. That is the stronger listed ultrawide pixel count of the two, but megapixels alone do not determine detail, low-light performance, color, or overall image quality.
vivo X300 FE: two 50MP OIS cameras and advertised zoom modes
vivo lists a 50MP IMX921 main camera with optical image stabilization (OIS), a 50MP IMX882 telephoto with OIS, and an 8MP wide-angle camera. Its product page advertises 3x, 10x, and 20x zoom modes. vivo also names the ZEISS Telephoto Extender Gen 2 as an accessory; its availability and compatibility should be confirmed before purchase.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For a camera decision, compare sample photos taken in similar lighting and at the same focal lengths, especially for ultrawide scenes, portraits, and distant subjects. The listed specifications cannot substitute for that like-for-like image-quality comparison.
Which has better battery and charging?
On listed capacity, the X300 FE leads with 6500mAh typical capacity (6350mAh minimum rated) versus the iQOO 12’s third-party-listed 5000mAh. That does not prove longer real-world endurance: screen settings, signal strength, apps, and workload affect battery life.
The iQOO 12 listing specifies faster wired charging at 120W. The X300 FE is listed by vivo with 90W wired charging and also advertises 40W wireless charging, which the comparison says is unavailable on the iQOO 12. Charging wattage does not guarantee a particular time to full; conditions and compatible charging equipment matter.

How should you compare performance?
The comparison listing names Snapdragon 8 Gen 3 for the iQOO 12 and Snapdragon 8 Gen 5 for the X300 FE. It also reports benchmark results, but those are measurements from one publisher; methodology, software versions, and repeatability are not established here. They are not enough to declare a reliable overall performance winner.
If gaming or sustained workloads are decisive, look for tests of both exact India models conducted under comparable conditions, including thermals and performance over time. The iQOO official India page cautions that laboratory results and parameters can vary. Do not treat a single benchmark score as a guarantee of day-to-day speed.
What is the price difference in India?
A dependable current price difference is not established. The third-party comparison’s displayed prices do not provide a reliable, matched current price for both phones, and an official store result did not yield a dependable comparison. Prices can vary by storage, retailer, date, and offer.
To work out the difference, compare the same storage tier at the same retailer on the same date. Keep the listed selling price separate from bank discounts, exchange bonuses, and other conditional offers; record whether each figure is a list price or an offer price. Without those matched figures, naming one phone as cheaper or quoting a rupee difference would be misleading.
Other details to check before buying
vivo says the X300 FE box includes a quick start guide, eject tool, case, applied protective film, warranty card, and USB power adapter. Its specification page lists IP68 and IP69 ratings under specified laboratory conditions and cautions that resistance may diminish over time; liquid damage may not be covered. Confirm the contents and protection rating for the exact iQOO 12 India SKU before treating either as a deciding advantage.

These are listing details, not a guide to current stock, software support, or retail availability.
Quick Recap
Which one should you choose?
- Choose the iQOO 12 5G if you want the larger listed display, a 50MP ultrawide camera on paper, or the higher listed wired charging rate.
- Choose the vivo X300 FE if you prefer a smaller listed display and body, want wireless charging, or prioritize its higher listed battery capacity and OIS-equipped main and telephoto cameras.
- Wait for matched prices before choosing on value. Compare identical storage tiers and separate unconditional prices from offers tied to a bank card or exchange.
