iPhone 15 vs Galaxy S24 vs Pixel 8: Which Flagship Phone Should You Buy?

Every year the same three phones end up on the same shortlist, and 2024 is no exception: Apple's iPhone 15, Samsung's Galaxy S24, and Google's Pixel 8. All three sit in roughly the same price band, all three are genuinely excellent, and all three are built around a different philosophy of what a flagship phone should prioritize. This flagship phone comparison walks through design, display, performance, cameras, battery, and software so you can match the right phone to how you actually use it, rather than to a spec sheet.

Design and build quality

The iPhone 15 finally drops the sharp stainless-steel-adjacent edges of older iPhones for a softer, contoured aluminum frame that is noticeably more comfortable to hold for long sessions, and it is the only one of the three offered in a genuinely compact 6.1-inch body without sacrificing flagship internals. The Galaxy S24 is nearly identical in footprint at 6.2 inches, wrapped in an Armor Aluminum frame with flat sides that Samsung has refined over several generations, and it feels the most "premium" in hand of the three thanks to its glass-and-metal sandwich. The Pixel 8 keeps Google's now-familiar camera bar design and a slightly more plasticky-feeling (though still Gorilla Glass Victus protected) back panel; it is the least distinctive-feeling of the three, but also the one most people find easiest to grip one-handed.

Display: three different priorities

Samsung wins the display spec sheet outright. The Galaxy S24's 6.2-inch Dynamic AMOLED 2X panel runs at 2340x1080 with a 120Hz refresh rate and gets meaningfully brighter in direct sunlight than either rival. The Pixel 8's 6.2-inch OLED panel also reaches up to 120Hz and 2400x1080, and in practice looks nearly as good outdoors, with slightly warmer, punchier default color tuning that some people prefer. The iPhone 15 is the outlier: its 6.1-inch Super Retina XDR OLED is capped at 60Hz, which sounds like a real disadvantage on paper and does feel a little less fluid when scrolling long pages, but Apple's color calibration and touch response are still class-leading, and most buyers coming from an older iPhone won't miss the higher refresh rate as much as spec sheets suggest they should.

Performance and chipsets

All three phones are fast enough that day-to-day use — messaging, browsing, social apps, light gaming — feels instant regardless of which you choose. The Galaxy S24 ships with either the Snapdragon 8 Gen 3 or Exynos 2400 depending on region, and the Snapdragon variant in particular posts the highest raw benchmark numbers of the group, which matters if you play graphically demanding mobile games. Apple's A16 Bionic in the iPhone 15 is a generation behind the chip in the iPhone 15 Pro, but it still comfortably outpaces most Android competition in single-core tasks and sustains performance well under load. The Pixel 8's Tensor G3 is the weakest of the three in synthetic benchmarks and can run warm under sustained gaming, but Google didn't design it to win benchmarks — it's tuned specifically to accelerate the on-device AI and camera processing that defines the Pixel experience.

Cameras: this is where they really diverge

The Galaxy S24 is the only one of the three with a genuine optical telephoto lens — a 10MP 3x sensor alongside its 50MP main and 12MP ultrawide — which makes it the clear pick if you photograph kids' sports games, concerts, or wildlife from a distance. The Pixel 8 sticks to a 50MP main plus 12MP ultrawide pairing, but its results consistently punch above the hardware thanks to Google's decade of work refining computational photography: features like Best Take, which merges multiple burst shots so nobody in a group photo is blinking, and Magic Eraser, which remains the most convincing object-removal tool on any phone, are genuinely useful rather than gimmicks. The iPhone 15 pairs a 48MP main sensor (with a useful 2x in-sensor crop) with a 12MP ultrawide, and while it lacks a true telephoto, its video recording quality — particularly Cinematic mode and Action mode stabilization — remains the benchmark the other two are still chasing.

Battery life and charging

The Galaxy S24's 4,000mAh cell and 25W wired charging give it the most flexible day-to-day battery performance of the group, especially with its 120Hz display dialed to adaptive refresh. The Pixel 8's larger 4,575mAh battery sounds like it should win outright, but Tensor G3's power draw during camera and AI tasks means real-world endurance lands closer to the Galaxy S24 than the capacity gap suggests. The iPhone 15's smaller 3,349mAh battery is the lowest on paper, yet iOS's tight hardware-software integration means it typically matches or slightly beats both Android phones in mixed-use battery testing — a reminder that raw mAh numbers rarely tell the whole story.

Software and long-term support

Samsung and Google now both commit to seven years of OS updates and security patches on these models, a genuinely industry-leading software update policy that means either phone bought today should still be receiving Android version upgrades in 2031. Apple doesn't publish a fixed number of years, but its actual track record of five-plus years of updates on older iPhones remains the longest-established precedent of any manufacturer. Where the two platforms differ most is customization: Samsung's One UI 6.1 piles on Galaxy AI features like Circle to Search and live translation on top of Android's flexibility, the Pixel's near-stock Android is the cleanest and fastest to update, and iOS remains the most locked-down but also the most consistent experience across the entire iPhone lineup.

Price and value

All three launched in the same general price range, and all three now show up regularly with meaningful carrier or retailer discounts, so list price alone shouldn't be the deciding factor. If you shop primarily by trade-in and resale value, the iPhone 15 consistently retains more of its original price after two to three years than either Android flagship — worth factoring in if you upgrade phones frequently. If you want the most camera-versatile phone for the money, the Galaxy S24 justifies its price with genuine zoom capability. If you want the smartest software experience without paying Pro-tier prices, the Pixel 8 is usually the best-discounted of the three.

Verdict: which should you actually buy

There isn't a single right answer here, which is exactly why this comparison exists instead of a ranked list. Buy the Galaxy S24 if you want the most complete all-around flagship with real optical zoom and the brightest screen. Buy the Pixel 8 if computational photography, a clean version of Android, and Google's AI features matter more to you than raw specs. Buy the iPhone 15 if you're staying in Apple's ecosystem, prioritize video quality, or care about resale value down the line.
