Samsung Galaxy S23 vs Galaxy S24: Design, size comparison, and colors

At first glance, you’d be hard-pressed to tell the difference between the Samsung Galaxy S23 and the Galaxy S24. They look nearly identical, with the same visual design elements like a metal frame and vertical camera housing on the back.

The footprint and weight of each respective device in nearly the same, although the Galaxy S24 lineup squeezes in slightly larger screens thanks to reduced bezel sizes. They are still Dynamic AMOLED, but each measures .1-inches larger than their predecessors.

In terms of colors, the Galaxy S23 and S23 Plus are available in Green, Phantom Black, Lavender, and Cream. The Galaxy S24 and S24 Plus are available in Cobalt Violet, Amber Yellow, Marble Gray, and Onyx Black.

Samsung Galaxy S23 vs Galaxy S24: Features

Based on the specs sheet, the Galaxy S24 is a relatively minor upgrade over the Galaxy S23. Most of the hardware is either identical or an iterative upgrade, making these devices look and feel very similar.

The Snapdragon 8 Gen 3 for Galaxy (or Exynos 2400 on global models) found on the Galaxy S24 is a slight improvement over the Snapdragon 8 Gen 2 for Galaxy found on the Galaxy S23, but you’re unlikely to notice a difference in everyday use. You might, however, get more use out of the Galaxy AI features added to the Galaxy S24 lineup, which include real-time translations, unique photo editing tools, and AI-powered text editing. The Galaxy S24 Plus also comes with 12GB of RAM, up from 8GB on the Galaxy S23 Plus. Battery sizes have also received a modest bump, increasing by 100mAh and 200mAh respectively, although charging speeds remain the same.

The Galaxy S24 will receive seven years of Android updates, up from four on the Galaxy S23.

The biggest upgrade here is nearly a footnote, but it can be the difference maker when deciding which device to buy. The Galaxy S24 series will receive seven years of Android version updates and security updates, matching the Google Pixel 8 series for the best support in the industry. For now, Samsung is only promising this support for the Galaxy S24 series, so the S23 series is stuck with the previous commitment of four years of Android version updates and five years of security updates. Since it launched with Android 13, it will receive support through Android 18 in 2027. The Galaxy S24 will receive updates until 2031, which is several lifetimes for a smartphone.

That said, both phones currently run Android 14, and although the Galaxy S24 ships with the latest One UI 6.1, it’s only a matter of time before the Galaxy S23 receives this update as well. Some of the Galaxy AI features mentioned above may also find their way onto the Galaxy S23, similar to Pixel drops on Google phones. Ultimately though, if you like to play with cutting-edge technology, the Galaxy S24 will tick that box.

Samsung Galaxy S23 vs Galaxy S24: Price and availability

Galaxy S24 9

  • Samsung Galaxy S23: Starts at $699
  • Samsung Galaxy S23 Plus: Starts at $999
  • Samsung Galaxy S24: Starts at $799
  • Samsung Galaxy S24 Plus: Starts at $999

The Galaxy S23 lineup went on sale on February 17, 2023, and it’s still available to purchase directly from Samsung. The base model starts at $699 and the Plus model starts at $999, although each has a more expensive variant with more built-in storage. As of 2024, you can now find the phones for well below retail.

The Galaxy S24 lineup was announced today, January 17, 2024, and is already up for pre-order. It will hit the shelves at the end of the month, on January 31, 2024. During the pre-order period, you can upgrade to higher storage limits free of charge, and if you pre-order through the official Samsung website, you’ll receive an extra $100 credit. Pricing is identical to the 2023 flagship launch pricing at $799 and $999, respectively.

Many other smartphone manufacturers have increased pricing in recent years, so Samsung maintaining the same retail price is a welcome surprise. That said, the Galaxy S24 Ultra did see a $100 increase in price this year, which makes the two cheaper models an even more attractive buy.

Samsung Galaxy S23 vs Galaxy S24: Which should you buy?

Galaxy S24 2
Damien Wilde / Android Authority

The Galaxy S23 and S24 are remarkably similar on the surface, offering many of the same hardware and software features. In fact, aside from an iterative SoC upgrade and a slight RAM boost in the Galaxy S24 Plus, the hardware is nearly identical. The Galaxy S24 lineup adds a few new AI features, but over time, they will make their way to older devices as well.

The seven-year commitment to updates makes the Galaxy S24 a clear winner.

But the new seven-year commitment to updates on the Galaxy S24 series makes it a clear winner. This will extend support for the phones into 2031, a full four years longer than the Galaxy S23. Who knows what the smartphone world will look like at that point, but the peace of mind is priceless. The pre-order offer that allows you to max out internal storage for no extra cost is just the icing on the cake.

That said, there are likely to be huge discounts on the Galaxy S23 lineup, and if you replace your phone every three years or so, the extra support is largely meaningless. Sure, you might lose out on some resale value in a few years, but the savings now might more than make up the difference.
