Key Differences
-
The iPhone Air has a 2.15 oz lighter build
It’s a lopsided result (5.82 oz for the iPhone Air, 7.97 oz for the vivo X300 Pro) and one of the main reasons to choose between them. A few grams won’t matter, but bigger gaps add up in a pocket or a small bag over a full day.
-
The vivo X300 Pro has 50% higher peak brightness
The spread here is large: 4,500 nits on the vivo X300 Pro versus 3,000 nits on the iPhone Air. Expect to notice it. Peak figures are usually reached only in short bursts or small areas of the screen, but a higher ceiling still helps outdoor visibility.
-
The vivo X300 Pro has an extra rear camera
Of all the specs we compared, this is one where the vivo X300 Pro makes its strongest case: 3 against 1. The count alone doesn’t guarantee quality, but the vivo X300 Pro gives you more lenses to choose from.
-
The iPhone Air has a 0.09 in slimmer body
The iPhone Air clearly leads on thickness, and 0.22 in versus 0.31 in is a difference that reaches well beyond the spec sheet. It’s a difference you mostly notice in the hand and in tight pockets.
-
The vivo X300 Pro has a sharper 50 MP selfie camera
On front camera, the vivo X300 Pro posts 50 MP against 18 MP for the iPhone Air, a gap big enough to feel in everyday use. A sharper selfie camera helps with video calls, vlogs and group selfies.

Display
vivo X300 Pro leads
The vivo X300 Pro clearly takes the display round. The vivo X300 Pro makes its case with 50% higher peak brightness. Peak brightness decides how readable the screen stays in direct sunlight and how punchy HDR content looks. If display is your priority, the vivo X300 Pro is the phone to pick.
Peak brightness
iPhone Air: 3,000 nits vivo X300 Pro: 4,500 nits If you use your phone outdoors a lot, the vivo X300 Pro’s brighter panel is the one that holds up better at midday.
Screen size
iPhone Air: 6.5 in vivo X300 Pro: 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
Too close to call
Swap one for the other and you’d lose nothing on performance. Both cover performance well enough that other priorities should break the tie.
CPU cores
iPhone Air: 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
Too close to call
This area ends level; whatever separates these two, it isn’t memory & storage. This section won’t settle the choice, so weigh the other areas more heavily.
Camera
vivo X300 Pro leads
The vivo X300 Pro wins the camera section decisively. The vivo X300 Pro scores with 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 Air: 1 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 Air: 18 MP vivo X300 Pro: 50 MP 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.
Battery & Charging
vivo X300 Pro leads
The vivo X300 Pro squeezes out a win in the battery & charging section. The vivo X300 Pro takes this one with faster 40 W wireless charging. If you rely on a wireless pad at your desk or bedside, the vivo X300 Pro refills quicker there. For anyone who cares most about battery & charging, the vivo X300 Pro is the safer choice.
Wireless charging
iPhone Air: 20 W vivo X300 Pro: 40 W Faster wireless charging makes a pad or stand more practical as your main way to top up.
Software & Updates
For software & updates, the differences are in the specifics (component names and types), so the table is the place to look.
