Key Differences
-
The iPhone 17 has a 1.73 oz lighter build
A clear win for the iPhone 17: 6.24 oz against 7.97 oz. Few specs in this matchup are as one-sided. Weight shows up every time you hold the phone above your face in bed or type one-handed for a long stretch.
-
The vivo X300 Pro has 50% higher peak brightness
Here the vivo X300 Pro pulls well ahead of the iPhone 17, with 4,500 nits compared to 3,000 nits. Peak brightness decides how readable the screen stays in direct sunlight and how punchy HDR content looks.
-
The vivo X300 Pro has an extra rear camera
The vivo X300 Pro doesn’t just edge this one; 3 against 2 is a lead you’ll feel. The count alone doesn’t guarantee quality, but the vivo X300 Pro gives you more lenses to choose from.
-
The vivo X300 Pro has a bigger top storage option
Big gap, real consequences. The vivo X300 Pro’s 1 TB versus the iPhone 17’s 512 GB changes how the two compare in daily use. Most buyers are fine with a base or middle tier, so this is a niche advantage, but a real one if you need it.
-
The vivo X300 Pro has a sharper 50 MP selfie camera
The iPhone 17 is clearly behind on front camera (18 MP against 50 MP), and that’s one of its biggest weak spots in this matchup. If you mainly use the front camera for calls, the gap is minor; if you post selfies often, the vivo X300 Pro’s extra resolution helps.

Display
vivo X300 Pro leads
In the display category, the vivo X300 Pro isn’t just ahead; it’s clearly ahead. Here the vivo X300 Pro offers 50% higher peak brightness. If you use your phone outdoors a lot, the vivo X300 Pro’s brighter panel is the one that holds up better at midday. The display verdict goes to the vivo X300 Pro.
Peak brightness
iPhone 17: 3,000 nits vivo X300 Pro: 4,500 nits Peak figures are usually reached only in short bursts or small areas of the screen, but a higher ceiling still helps outdoor visibility.
Screen size
iPhone 17: 6.3 in vivo X300 Pro: 6.8 in Screen size is personal. If you watch a lot on your phone, the extra area pays off; if you text one-handed on the go, compact is kinder.
Performance
Too close to call
You can skip ahead if performance was your deciding factor: the two are evenly matched here. For performance, pick whichever you prefer for other reasons.
CPU cores
iPhone 17: 6 vivo X300 Pro: 8 Core count on its own says little about speed; how the chip is designed and how fast each core runs matter more.
Memory & Storage
vivo X300 Pro leads
The vivo X300 Pro has the slight upper hand on memory & storage. In its favor, the vivo X300 Pro has a bigger top storage option. 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. So if memory & storage tops your list, lean toward the vivo X300 Pro.
Max storage
iPhone 17: 512 GB vivo X300 Pro: 1 TB Heavy video shooters and people with large offline libraries benefit from the vivo X300 Pro’s bigger maximum.
Camera
vivo X300 Pro leads
The camera comparison is one-sided. The vivo X300 Pro leads where it counts. On the vivo X300 Pro, you get an extra rear camera. More cameras help most when each covers a different view, so check the table to see what the vivo X300 Pro’s extra lens adds. The takeaway: on camera, the vivo X300 Pro is the stronger phone.
Rear cameras
iPhone 17: 2 vivo X300 Pro: 3 An extra rear camera usually means another focal length (ultra-wide, telephoto or macro) and more freedom in framing.
Front camera
iPhone 17: 18 MP vivo X300 Pro: 50 MP Front cameras are often an afterthought, so a higher-resolution sensor is a small but welcome edge for the vivo X300 Pro.
Battery & Charging
vivo X300 Pro leads
The vivo X300 Pro takes battery & charging by a nose. The vivo X300 Pro adds faster 40 W wireless charging. Faster wireless charging makes a pad or stand more practical as your main way to top up. Anyone shopping mainly on battery & charging should start with the vivo X300 Pro.
Wireless charging
iPhone 17: 25 W vivo X300 Pro: 40 W If you rely on a wireless pad at your desk or bedside, the vivo X300 Pro refills quicker there.
Software & Updates
On software & updates, the useful details are the names in the table: what each one uses, not a figure we can rank.
