Features

Both the iPhone 12 and Galaxy S21 lineups are feature-packed, with just about anything you could want in a smartphone. They’ve got excellent camera performance, top-notch specs, and head-turning designs.

Each phone has multiple camera lenses. The iPhone 12 Mini and iPhone 12 both have 12MP wide-angle and 12MP ultra-wide lenses. The Galaxy S21 and S21 Plus also have 12MP wide-angle and ultra-wide sensors, with an additional 64MP telephoto shooter that should provide much better long-distance photos (if you’re into that kind of thing).

To get a telephoto lens on the iPhone, you’ll have to step up to the 12 Pro or 12 Pro Max models, which have an additional 12MP sensor. The latter also has a larger main sensor for improved low light performance. The Galaxy S21 Ultra takes things to a whole other level, with a 108MP wide-angle, two 12MP telephoto (3x and 10x), and 12MP ultra-wide cameras. This makes it the most versatile of the bunch, but ultimately the best photos will come down to software tuning — stay tuned for our own testing.

As for the specs, you’re getting top-of-the-line performance no matter which phone you buy. Both the Snapdragon 888 and Apple Bionic A14 processors are best-in-class. Unlike in previous years, the Samsung Exynos 2100 shouldn’t be too far behind either based on initial impressions. The Galaxy models have more RAM, but due to iOS optimization, you won’t notice a difference.

The main thing that separates each of these phones is size. The iPhone 12 Mini is the smallest of the bunch, measuring just 5.4-inches. The standard iPhone 12 is also smaller than the smallest Galaxy S21 phone, at 6.1-inches vs 6.2-inches. The largest devices are 6.7-inches and 6.8-inches, with the Galaxy S21 Ultra barely edging out the iPhone 12 Pro Max as the largest option available.

When it comes to truly unique features, however, the Galaxy S21 Ultra is the only one that’s a leg ahead. This year, for the first time, it will have S Pen support something that was previously exclusive to the Galaxy Note series.

  • Galaxy S21: $799/€849/£769
  • S21 Plus: $999/€1,049/£949
  • S21 Ultra: $1,199/€1,249/£1,149
  • iPhone 12 Mini: $699/€809/£699

  • iPhone 12 Pro: $999/€1,159/£999
  • iPhone 12 Pro Max: $1,099/€1.259/£1,099

When it comes to pricing, Samsung has stepped back from the exorbitant prices of last year’s Galaxy S20 lineup. Each of the new phones starts $200 cheaper than their predecessors. This makes them attractive options for anyone looking for a flagship Android phone.

The Apple iPhone models are also relatively affordable, with the iPhone 12 Mini providing an inexpensive entryway into the iOS ecosystem. If you can, however, it’s worth bumping up to the iPhone 12 for the added screen real estate.

The highest-end iPhone 12 Pro Max starts at $1,099, which is a bit less than the Galaxy S21 Ultra. Considering Samsung’s offering has more impressive camera optics (on paper) and S Pen support, it may warrant spending a bit more.

That said, you’ll have to buy the S Pen separately, which will run you about $30. It’s also worth noting that none of these phones come with chargers in the box. You’ll therefore have to shell out even more if you don’t have one handy.

Apple iPhone 12 series Four to choose from
There are a total of four new iPhones in Apple's iPhone 12 lineup: the iPhone 12, iPhone 12 Mini, iPhone 12 Pro, and iPhone 12 Pro Max. Brighter displays, faster processors, and more durable build quality are what you can expect with all four of these new phones.

Usually, it’s easy to declare a winner in at least a few categories, but when it comes to the Galaxy S21 series vs the Apple iPhone 12 series, it’s not so simple. All of the phones in each lineup perform extremely well. You’re unlikely to be disappointed no matter which one you pick.

That said, for the very budget-conscious the iPhone 12 Mini is a great option. It starts at $699, which is a full $100 less than the cheapest Galaxy S21 phone. It does, however, have huge bezels, a small screen, and somewhat limited battery life.

Between the iPhone 12/12 Pro and the Galaxy S21/S21 Plus, the choice will likely come down to whether you want to use Android or iOS. Pricing is almost identical in the US, although in the rest of the world the Galaxy S21 series is slightly cheaper. Feature sets are also very similar. Nevertheless, the S21 series offers larger screens.

If you can afford the best flagship smartphones out there, the Galaxy S21 Ultra and iPhone 12 Pro Max are fantastic options. S Pen support is a nice touch on the S21 Ultra, but if what you’re looking for is everyday performance and great cameras, they’re both first-in-class. Granted, they’re also very large so be prepared to use them two-handed.

Another thing to keep in mind is that only the iPhone 12 series has officially been released. You can pre-order the Galaxy S21 devices, but they won’t ship until the end of January. We’ll revisit this comparison once we’ve had more hands-on time with Samsung’s latest. Stay tuned for more info soon!
