Key Differences
-
The vivo X300 Ultra has a higher-resolution 200 MP main camera
The vivo X300 Ultra clearly leads on main camera, and 200 MP versus 48 MP is a difference that reaches well beyond the spec sheet. Megapixels are only one part of image quality, so treat this as a sign of detail potential, not a verdict on photos.
-
The vivo X300 Ultra has a dedicated 200 MP telephoto camera
On telephoto camera, the vivo X300 Ultra posts 200 MP against 48 MP for the iPhone 18 Pro, a gap big enough to feel in everyday use. Telephoto lenses earn their keep at concerts, school events and portraits: anywhere you can’t simply walk closer.
-
The vivo X300 Ultra has a 144 Hz display instead of 120 Hz
On refresh rate, the vivo X300 Ultra edges out the iPhone 18 Pro, 144 Hz to 120 Hz. A higher refresh rate makes scrolling, animations and games look smoother. Once you’re used to it, a lower-rate screen can feel sluggish by comparison.
-
The iPhone 18 Pro has a 0.74 oz lighter build
Don’t expect a night-and-day difference here. 7.44 oz against 8.18 oz is a small but genuine lead for the iPhone 18 Pro. A few grams won’t matter, but bigger gaps add up in a pocket or a small bag over a full day.
-
The iPhone 18 Pro has a bigger top storage option
This is one of the widest gaps in the whole comparison: 2 TB for the iPhone 18 Pro versus 1 TB for the vivo X300 Ultra. The top storage option only matters if you plan to buy a high-capacity version, but it caps how much you can ever keep on the phone.

Display
vivo X300 Ultra leads
If you’re keeping score, the display point goes narrowly to the vivo X300 Ultra. Choose the vivo X300 Ultra and you get a 144 Hz display instead of 120 Hz. Smoother motion is one of the most visible display upgrades, and adaptive high-refresh panels can slow down on static content to save power. If display is your priority, the vivo X300 Ultra is the phone to pick.
Refresh rate
iPhone 18 Pro: 120 Hz vivo X300 Ultra: 144 Hz You notice refresh rate every time you scroll a feed or a web page, which is why the vivo X300 Ultra feels more fluid in everyday use.
Screen size
iPhone 18 Pro: 6.3 in vivo X300 Ultra: 6.8 in A larger display also means a larger phone overall, so this is as much about your hands and pockets as it is about the picture.
Performance
iPhone 18 Pro leads
In the performance category, the iPhone 18 Pro is a step ahead rather than a leap ahead. Point to the iPhone 18 Pro for a newer 2 nm chip process. A finer process node generally lets a chip do the same work with less power, which can mean cooler running and better battery life. So if performance tops your list, lean toward the iPhone 18 Pro.
Process node
iPhone 18 Pro: 2 nm vivo X300 Ultra: 3 nm The iPhone 18 Pro’s chip is built on a more advanced process. That usually points to efficiency gains, though chip design matters just as much.
CPU cores
iPhone 18 Pro: 6 vivo X300 Ultra: 8 Phone chips mix large and small cores, so a different count mostly reflects a different design rather than a clear speed gap.
Memory & Storage
iPhone 18 Pro leads
The vivo X300 Ultra keeps it close on memory & storage, yet the iPhone 18 Pro holds a small lead. The iPhone 18 Pro answers with a bigger top storage option. Heavy video shooters and people with large offline libraries benefit from the iPhone 18 Pro’s bigger maximum. Net result: the iPhone 18 Pro leads this part of the comparison.
Max storage
iPhone 18 Pro: 2 TB vivo X300 Ultra: 1 TB Most buyers are fine with a base or middle tier, so this is a niche advantage, but a real one if you need it.
Camera
vivo X300 Ultra leads
The vivo X300 Ultra dominates the camera section, and the gaps are large enough to matter in daily use. The vivo X300 Ultra wins here with a higher-resolution 200 MP main camera. More megapixels on the main camera allow bigger crops and more detail in good light, but sensor size and processing matter just as much. For camera, the vivo X300 Ultra is the one to beat.
Main camera
iPhone 18 Pro: 48 MP vivo X300 Ultra: 200 MP The vivo X300 Ultra’s higher-resolution main sensor gives you more room to crop, which helps when you can’t get closer.
Telephoto camera
iPhone 18 Pro: 48 MP vivo X300 Ultra: 200 MP A dedicated telephoto camera captures distant subjects and portraits without heavy cropping, which keeps detail intact.
Battery & Charging
vivo X300 Ultra leads
The vivo X300 Ultra squeezes out a win in the battery & charging section. The vivo X300 Ultra scores with faster 40 W wireless charging. Wireless charging is usually slower than a cable, so this edge matters mainly to people who value the convenience. That makes the vivo X300 Ultra the natural choice for buyers focused on battery & charging.
Wireless charging
iPhone 18 Pro: 25 W vivo X300 Ultra: 40 W If you rely on a wireless pad at your desk or bedside, the vivo X300 Ultra refills quicker there.
