In short
Buy a used Galaxy S24 if you want a compact Samsung with years of support left: its seven-year update promise has more than four years to run. It has a 6.2-inch FHD+ screen, the Snapdragon 8 Gen 3, 8GB of RAM and a 3x telephoto. Skip it if you charge in a hurry or zoom far: it charges at 25W, while the S24 Ultra takes 45W and adds a 5x telephoto.
Who it is for
- Anyone who wants a small phone. At 6.2 inches and 5.93 oz, it's the compact model of the S24 series.
- Used buyers who want a phone that stays supported for years after they buy it.
- People who mostly shoot with the main camera. The 50MP sensor has optical stabilization, and the 3x telephoto handles moderate zoom.
Who should skip it
- Heavy multitaskers. Every S24 has 8GB of RAM; the S25 moved to 12GB.
- Anyone who wants fast charging. The S24 is rated for 25W, or 50% in about 30 minutes; the S24 Ultra charges at 45W.
- Zoom fans. The telephoto stops at 3x, while the S24 Ultra adds a 200MP main camera and a 5x telephoto.
What sets it apart
- The same seven generations of Android upgrades and seven years of security updates as the S24+ and S24 Ultra.
- The lowest launch price in the S24 series, $799.99.
- The Snapdragon 8 Gen 3, a generation newer than the S23's 8 Gen 2.
- A 50MP main camera with optical stabilization, a 12MP ultra-wide and a 10MP 3x telephoto.
- A 6.2-inch FHD+ Dynamic AMOLED 2X screen that adjusts its refresh rate from 1Hz to 120Hz.
Caveats
- Storage starts at 128GB, and every model has 8GB of RAM.
- The 25W adapter is sold separately, and the 50%-in-30-minutes figure assumes it and a 3A USB-C cable.
- Samsung gives no brightness rating or battery-life hours for the S24.

Samsung Galaxy S24 extras
Specs only this model has.
| Spec | Value | Source and notes |
|---|---|---|
| RAM vs S25 | 8 + 128GB or 8 + 256GB; the S25 has 12GB | Samsung US Newsroom, S24 series |
| Wi-Fi generation | Wi-Fi 6E here and on the Plus; Wi-Fi 7 on the Ultra | Samsung US Newsroom, S24 series |
| S Pen | No; Samsung names the S Pen only for the Ultra, not the S24 or S24+ | Samsung US Newsroom, S24 series |
| Update promise | Seven Android upgrades and seven years of security updates, the same on every model in the series (footnote 32) | Samsung US Newsroom, S24 series |
The S24 arrived in January 2024 at the same Galaxy Unpacked as the first titanium Ultra, and went on sale on 31 January 2024 at $799.99. It’s the small one of the three, launched with Galaxy AI and the same seven-year update promise as its bigger siblings.
More than four years of updates to come
Samsung promises seven generations of Android upgrades, starting from Android 14 and One UI 6.1, and seven years of security updates. Counted from the January 2024 launch, that leaves more than four years of security patches as of September 2026. For a used phone, that’s the strongest argument in its favor: you can buy one now and still be covered for years.
S24 or S25?
| Spec | Galaxy S24 | Galaxy S25 |
|---|---|---|
| Chip | Snapdragon 8 Gen 3 | Snapdragon 8 Elite |
| RAM | 8GB | 12GB |
| Wi-Fi | Wi-Fi 6E | Wi-Fi 7 |
| Bluetooth | 5.3 | 5.4 |
| Thickness | 7.6 mm | 7.2 mm |
| Weight | 5.93 oz | 162 g |
The S25 is the better-equipped phone: half again as much memory, a newer chip and newer wireless standards, in a slightly thinner body. Converting Samsung’s 5.93 oz, it’s also about six grams lighter. If the price gap between them is small, take the S25.
Cameras: 50MP main, 3x telephoto
The S24’s main camera is a 50MP sensor at F1.8 with optical image stabilization. Beside it sit a 12MP ultra-wide with a 120-degree view and a 10MP telephoto with 3x optical zoom, and the selfie camera is 12MP. Samsung doesn’t publish video resolutions for the S24; its announcement names Instant Slow-mo and Super HDR across the series.
For more reach, the S24 Ultra adds a 200MP main camera and a 5x telephoto.
Battery and charging
The battery is 4,000 mAh typical (3,880 mAh rated under IEC 61960). With a 25W adapter and a 3A USB-C cable it gets to 50% in around 30 minutes; the adapter is sold separately and the phone works with USB PD chargers. Fast Wireless Charging 2.0 and Wireless PowerShare are built in.
Screen and build
The 6.2-inch Dynamic AMOLED 2X screen is FHD+, 6.0 inches once the rounded corners are counted, and its refresh rate moves between 1Hz and 120Hz. Vision booster is on board. Samsung gives a peak brightness of 2,600 nits only for the S24 Ultra, not for this model.
Its IP68 rating covers up to 1.5 meters of fresh water for up to 30 minutes. The S24 series was the first S series to use recycled steel and TPU, and the S24’s battery contains at least 10% recycled cobalt, against 50% in the S24+ and Ultra. Colors were Onyx Black, Marble Gray, Cobalt Violet and Amber Yellow, plus Jade Green, Sapphire Blue and Sandstone Orange from Samsung.com.
Price
The S24 launched at $799.99 in the US with 128GB, and there’s a 256GB model; both have 8GB of RAM. Above it, the S24+ cost $999.99 and the S24 Ultra $1,299.99. Samsung has moved on (the Galaxy S26 Ultra is its current top phone), so an S24 now comes used or refurbished. Condition and storage change the price a lot, so check before you buy.
