The processor change and the increase in RAM memory represent the biggest leap from one generation to the next, promising a more fluid experience prepared for the most demanding applications and games on the market. Além Furthermore, the optimization of energy consumption stands out as an important differentiator, even with the maintenance of battery capacity.
Design and durability of devices
The Galaxy S24, launched in 2024, sets a premium construction standard, combining Armor Aluminum sides with a tough glass back panel. The device is IP68 certified, which guarantees protection against water and dust, supporting immersion of up to 1.5 meters for 30 minutes. Tanto the screen and back panel are protected by Gorilla Glass Victus 2, offering high resistance against scratches and everyday impacts. The new generation, the Galaxy S25, maintains this same philosophy of robust construction, using the glass back and sides of the Armor Aluminum, in addition to preserving the IP68 certification and the Gorilla Glass Victus 2 protection. with the S24’s 147 x 70.6 x 7.6 mm and 168 grams, a difference that can positively impact ergonomics and comfort during prolonged use.
Improvements in performance and RAM memory
The Galaxy S24 is equipped with the Exynos 2400 processor, developed by Samsung itself, accompanied by 8 GB of RAM and storage options of 128 GB, 256 GB or 512 GB. Este chip demonstrates robust performance for everyday tasks and is capable of running graphics-demanding games without difficulty, achieving around 1.6 million points in the AnTuTu benchmark test, an indicator of its processing capacity.
On the other hand, the Galaxy S25 considerably raises the performance level by adopting the Qualcomm Snapdragon 8 Elite processor, which works together with 12 GB of RAM, maintaining the same storage options as its predecessor. Choosing this Qualcomm chipset results in significantly higher performance, as its most powerful core operates at a frequency of 4.47 GHz, while that of the S24 reaches 3.2 GHz.
This difference in clock speed directly reflects the S25’s ability to deliver notably improved performance, especially in heavy applications, intensive multitasking and graphics-intensive games. Nos AnTuTu tests, the latest model achieved an impressive 2.1 million points, consolidating its position in terms of processing power and offering a more fluid interface for the most demanding users.
Visual experience with the screen
Both models, both the Galaxy S24 and the Galaxy S25, share identical display specifications, offering a high-quality visual experience. Eles are equipped with a 6.2-inch Dynamic LTPO AMOLED 2X display, which stands out for its vivid colors and depth of black tones.
The resolution remains at 1080 x 2340 pixels, ensuring sharp and detailed images. The screen also offers a refresh rate of 120Hz, HDR10+ support and a peak brightness of 2600 nits, which ensures vibrant colors and excellent visibility even in bright sunlight.
Battery and recharge autonomy
The Galaxy S24 comes with a 4000 mAh battery and supports 25W wired, 15W wireless, and 4.5W reverse charging. In autonomy tests, the device completed all stages with 5% charge remaining, demonstrating sufficient capacity for a full day of moderate to intense use.
Although the Galaxy S25 maintains the same battery capacity of 4000 mAh and the same charging powers, there has been a notable improvement in energy efficiency. Nos same tests, the S25 completed the steps with 12% charge remaining, indicating that software and hardware optimization resulted in greater durability.
This greater efficiency gives the user more time away from the socket, expanding the possibilities of using the device throughout the day and on long trips without compromising convenience.
Analysis of photographic capabilities
The Galaxy S24 is equipped with a triple rear camera system, which includes a 50 MP main sensor with optical image stabilization (OIS), a 10 MP telephoto lens with 3x optical zoom, and a 12 MP ultrawide lens with a 120-degree field of view. Para selfies and video calls, the device has a 12 MP front sensor and is capable of recording videos in resolutions of up to 8K at 30 frames per second, ensuring high image quality.
Interestingly, Samsung chose to keep exactly the same set of cameras on the Galaxy S25. Essa decision means that there were no updates to the sensor hardware or lenses between the two generations. Para users, this indicates that the quality of photo and video capture, in terms of resolution and basic functionalities, will remain identical to that of the previous model, with the focus of the new device’s improvements directed to other areas, such as general performance.
Prices and current cost-benefit
The Galaxy S24 was introduced to the market with a launch price of R$5,999. Contudo, a year after its arrival and with the launch of new models, its value was adjusted, making it possible to find it in promotions for approximately R$3,500. Essa devaluation is a common movement in the high-end smartphone market.
The Galaxy S25, launched in January 2025, reached Brasil with a slightly higher starting price of R$6,999. However, a few months later, its market value also began to correct.
Currently, the S25 can be found in several offers for a price close to R$3,500. Este rapid price alignment between generations raises questions about the real added value of the latest model at the time of purchase.
The proximity of values can lead consumers to carefully analyze which model offers the best value for money, comparing the differences in performance and extra features with the necessary investment.
Connectivity and operating system
Both generations offer a solid foundation of connectivity, but the S25 brings important updates. The Galaxy S24 was released with the One UI 6.1 based on the Android 14, and Samsung has secured a seven-year commitment of system and security updates. In terms of connectivity, the device offers Wi-Fi 6E, Bluetooth 5.3, support for 5G networks, GPS, NFC and an ultrasonic fingerprint reader under the screen, as well as stereo speakers for better audio quality.
In turn, the Galaxy S25 hits the market running the One UI 8 based on the Android 15, maintaining the same seven-year period of support for updates. Embora preserves most of the connectivity features of its predecessor, the S25 introduces significant improvements with the inclusion of Wi-Fi 7 and Bluetooth 5.4. The adoption of Wi-Fi 7 promises even higher connection speeds and lower latency, optimizing high-resolution content streaming and online gaming. Já o Bluetooth 5.4 improves the connection with wireless accessories, ensuring greater stability and energy efficiency.
