Galaxy S27 vs iPhone 18: Expected specifications side by side

Camera comparison: the lens choice matters more than 50MP vs 48MP

The two main cameras are listed with the same 1/1.56-inch sensor format. The two-megapixel difference tells us little about which phone would take a better photo. The more useful distinction is what happens when you want to frame a shot wider or closer.

Galaxy S27 for 3x framing; iPhone 18 for ultrawide and selfie resolution

At a school performance or sporting event, the Galaxy S27’s rumored 10MP telephoto would give you a dedicated 3x optical view from your seat. The absence of a dedicated telephoto on the iPhone 18 would not rule out zoom through cropping or image processing.

For landscapes and group photos, the iPhone 18 is tipped to use a 48MP ultrawide, compared with 12MP on the Galaxy. Its expected 18MP front camera also exceeds the Galaxy’s 12MP count. Whether those extra pixels translate into better detail, particularly indoors, will require camera samples.

Display, charging and USB: where the numbers diverge

Although both screens are listed at 6.3 inches and 120Hz, the iPhone’s rumored resolution works out to roughly 458 pixels per inch, compared with 409 on the Galaxy. That gives the iPhone a pixel-density advantage on paper. The processor names alone, however, tell us little about how the Exynos 2700 and A20 would compare in games or everyday use.

The expected battery capacities differ by just 130mAh. Charging is the larger distinction: the iPhone is tipped for 40W wired and 25W MagSafe charging, versus 25W wired and 15W wireless on the Galaxy. Those ratings do not establish full-charge times or which phone would last longer between charges.

Samsung’s expected USB 3.2 Gen 1 connection could make the Galaxy the more practical choice for transferring large video files to a computer. The iPhone’s listed USB 2.0 standard concerns data transfer; it does not contradict the higher wired charging figure.

Expected price and what it means for buyers

At the same rumored $999, the strongest case for the Galaxy S27 is its combination of optical reach and faster wired file transfers. The iPhone 18’s strongest advantages on paper are its denser display, higher-resolution ultrawide and faster charging ratings.
