Top 6 Best-Selling Smartphones in 2024: Head-to-Head Comparison

The 2024 smartphone landscape was defined by premiumization, AI hype, and the continued dominance of Apple and Samsung. According to Counterpoint Research, the iPhone 15 was the world's best-selling smartphone for the entire year, followed by the iPhone 15 Pro Max and iPhone 15 Pro in second and third place.

Samsung secured four spots in the global top 10, up from three in 2023, with the Galaxy S24 Ultra marking the first time an S-series flagship returned to the list since 2018.

What's striking is that only Apple and Samsung models made the top 10 for the third consecutive year—no Chinese brands, no Google Pixels. The iPhone 14, despite being a year old, still ranked 8th globally due to aggressive carrier discounts and its role as Apple's entry-level option after price cuts.

The shift toward premium devices accelerated dramatically. One-quarter of consumers who purchased smartphones in 2024 spent more than $600, driven by AI features, longer replacement cycles, and interest-free financing. Samsung's early adoption of generative AI with features like Circle to Search and real-time translation proved to be a key differentiator, while Apple Intelligence features remained limited to newer Pro models.

Budget champions also emerged. The Samsung Galaxy A15 (4G and 5G variants) and Xiaomi's Redmi Note 13 Pro carved out massive market share in emerging markets, offering 90Hz+ displays, 50MP cameras, and 5000mAh batteries at $150-300 price points. These phones proved that 'good enough' is now genuinely good.

Specifications tell part of the camera story, but real-world performance reveals the truth. I've tested all six phones extensively, and here's what actually matters:

Daylight Photography: The iPhone 15 and Galaxy S24 are tied for overall versatility. The iPhone's 48MP sensor delivers excellent detail and Apple's processing nails color accuracy every time. The Galaxy S24's 10MP 3x telephoto gives it an edge for distant subjects—something the iPhone 15 lacks.

Google's Pixel 8 produces the most natural-looking images with superior dynamic range, though its colors can look muted compared to Samsung's punchier processing.

Low-Light Performance: The Pixel 8 wins decisively. Google's Night Sight remains unmatched, pulling detail from shadows that look like pure noise on other phones. The iPhone 15 is second, with excellent stabilization and natural color rendering. The Galaxy S24 tends to oversharpen and oversaturate in low light, though recent updates have improved this.

Portrait Mode: All three flagships deliver excellent portrait shots with accurate edge detection. The Pixel 8's computational photography creates the most natural bokeh, while the iPhone 15 has the most consistent skin tones across different lighting. The Galaxy S24's portraits can look over-processed.

Video Quality: The iPhone 15 dominates. Apple's video stabilization, HDR processing (Dolby Vision), and consistent exposure during recording are unmatched. The Galaxy S24 is close, with excellent 8K recording and low-light video. The Pixel 8's video quality lags behind—Google's Tensor chip struggles with real-time video processing, leading to occasional frame drops and less refined stabilization.

Budget Camera Reality: The Galaxy A54 and Redmi Note 13 Pro deliver surprisingly good daylight photos, but low-light performance collapses quickly. The Redmi's 200MP sensor is mostly marketing—photos are pixel-binned to 12.5MP and lack the computational magic of flagship processors. Video quality on both is mediocre at best.

Samsung sets the display standard. The Galaxy S24's 2600-nit peak brightness and 120Hz LTPO panel are objectively superior to everything else here. Colors are vibrant (sometimes overly so), blacks are perfect, and outdoor visibility is excellent. The Galaxy A54 inherits much of this display tech—its 120Hz Super AMOLED panel is brighter than the iPhone 14's screen.

Apple's decision to reserve 120Hz for Pro models remains indefensible. The iPhone 15's 60Hz display is smooth enough for most tasks, but once you've used 120Hz, going back feels like a downgrade. The 2000-nit peak brightness is excellent for HDR content, but Samsung's panel is noticeably brighter outdoors.

Apple's color accuracy is technically superior—displays are calibrated to DCI-P3 with professional precision.

The Pixel 8's Actua display hits 120Hz and 2000 nits, making it functionally equivalent to the iPhone 15's screen. Google's color tuning is more neutral than Samsung's but warmer than Apple's. The bezels are slightly thicker than competitors, giving it a less premium look.

Design Trends: All six phones have converged on similar aesthetics—glass sandwich designs with metal frames. The iPhone 15's color-infused glass backs look distinctive, while Samsung's matte finishes resist fingerprints better. Google's Pixel 8 has a unique horizontal camera bar that's polarizing—I find it gives the phone character, but many consider it ugly.

Build quality on budget phones has improved dramatically: the Galaxy A54 feels surprisingly premium for $449, though the plastic frame is noticeable in hand.

Battery life is where budget phones shine. The Galaxy A54 and Redmi Note 13 Pro, both packing 5,000 mAh batteries, consistently delivered 6-7 hours of screen-on time in my testing—easily lasting a full day of heavy use. The Pixel 8's 4,575 mAh battery performed similarly, lasting 5-6 hours screen-on time thanks to efficient optimization.

The iPhone 15 and Galaxy S24 tell a different story. Their smaller batteries (3,349 mAh and 4,000 mAh respectively) mean moderate-to-heavy users will need a mid-day top-up. The iPhone 15 averaged 4-5 hours screen-on time, while the Galaxy S24's more powerful Snapdragon chip pushed it to around 4 hours. Both phones prioritize thin designs over battery capacity—a trade-off I disagree with.

Charging Speed Reality: Apple's 20W charging is embarrassingly slow in 2024. The iPhone 15 takes 90+ minutes to fully charge. Samsung's 25W is better but still mediocre at 70 minutes. Google's 27W gets you to 50% in about 30 minutes. The real winner? Xiaomi's 67W charging hits 50% in just 15 minutes and full charge in under 40 minutes.

Budget Chinese phones have leapfrogged flagships in charging technology.

Wireless Charging: Only the three flagships support wireless charging—15W MagSafe for iPhones, 15W Qi for Samsung, and 18W for the Pixel 8. MagSafe's magnetic alignment is genuinely useful, making nightstand charging foolproof. The Galaxy A54 and Redmi Note 13 Pro's lack of wireless charging is a notable omission but understandable at their price points.

Software updates became the surprise differentiator in 2024. Samsung and Google both committed to 7 years of OS and security updates for their flagships—matching Apple's typical support window and crushing everyone else in the Android ecosystem. The Galaxy S24 and Pixel 8 will receive updates through 2031, making them viable long-term purchases.

Apple's iOS remains the gold standard for polish and ecosystem integration. Features like Handoff, AirDrop, and iMessage lock you into the Apple universe, but they work flawlessly. iOS 17 runs identically smooth on the iPhone 15 and iPhone 14—Apple's optimization is unmatched. The downside is limited customization and Apple's walled-garden approach.

One UI vs. Stock Android: Samsung's One UI 6 has matured into a feature-rich experience, but it's still cluttered. You get powerful multitasking, extensive customization options, and Samsung's DeX desktop mode. But you'll also deal with duplicate apps (Samsung and Google versions of everything), aggressive battery optimization that kills background apps, and occasional lag on mid-range hardware.

Google's Pixel 8 offers stock Android 14—clean, fast, and bloat-free. You get features like call screening, live transcription, and Recorder app transcription that actually work. Updates arrive instantly. The trade-off is fewer customization options and no desktop mode. If you value simplicity over features, Pixel is the way.

Budget Reality: The Galaxy A54 gets 4 OS updates and 5 years of security patches—respectable for $449. The Redmi Note 13 Pro's 3 years of updates is weak, and Xiaomi's track record for timely delivery is poor. MIUI 14 is feature-rich but ad-laden and bloated. You're trading software polish for hardware value.

The price-to-performance ratio has never been more skewed. The iPhone 15 and Galaxy S24 cost $799—2.3x more than the Redmi Note 13 Pro—but don't deliver 2.3x better experiences. You're paying for:

Ecosystem lock-in and brand premium: Apple charges $200+ more than comparable Android hardware because of iMessage, AirDrop, and status signaling. Samsung charges flagship prices for displays and cameras that are only marginally better than mid-range competitors.

Camera processing power: Flagship chips enable computational photography magic—Night Sight, Magic Eraser, ProRAW. Budget phones lack the processing muscle for real-time HDR and advanced AI features. This is where the price gap feels justified.

Software support longevity: 7 years of updates on Pixel 8 and Galaxy S24 vs. 3 years on Redmi Note 13 Pro means flagships remain secure and functional far longer. Over a 5-year ownership period, the per-year cost difference shrinks significantly.

Build quality and durability: IP68 vs IP54 water resistance, Gorilla Glass Victus vs. standard Gorilla Glass, metal vs. plastic frames—these differences matter for long-term durability and resale value.

The sweet spot in 2024 is $400-500. The Galaxy A54 delivers 80% of flagship performance for 56% of the price. That's where value peaks. Above $700, you're paying exponentially more for diminishing returns. Below $300, compromises pile up quickly—weak processors, mediocre cameras, and poor software support.
