The design of smartphones is often a determining criterion in choosing a device. The Galaxy A15 offers a clean and minimalist appearance with its photo sensors simply placed on the rear shell, available in midnight blue, light blue, and lime (yellow) with a matte finish. On the other hand, the Galaxy S24 and Galaxy S24 Ultra have a more sophisticated appearance, with photo sensors also arranged in a minimalist manner on the rear shell. The Galaxy S24 comes in black, silver, indigo (purple), and cream, while the S24 Ultra comes in black, gray, purple, and amber (yellow), with a titanium frame, providing extra robustness. The profile of the Galaxy S24 and S24 Ultra is flatter overall compared to the Galaxy A15, which has softer curves.
In terms of dimensions, the Galaxy A15 measures 160.1 mm in height, 76.8 mm in width, and 8.4 mm in thickness, for a weight of 200 grams. The Galaxy S24 is more compact at 147 mm in height, 70.6 mm in width, and 7.6 mm in thickness, and weighs only 167 grams, making it the lightest model. The Galaxy S24 Ultra, on the other hand, is the largest and heaviest at 162.3 mm in height, 79 mm in width, 8.6 mm in thickness, and a weight of 232 grams. So, for those who prioritize lightness and compactness, the Galaxy S24 is the most suitable, while the S24 Ultra will suit you better if you are looking for a large screen and a more pronounced presence.
Battery capacity is a key factor in battery life. The Galaxy A15 and Galaxy S24 Ultra each have a 5,000mAh battery, potentially offering the longest battery life of the three models. In contrast, the Galaxy S24 has a 4,000mAh battery, which could result in slightly lower battery life. In terms of charging speed, the Galaxy A15 and S24 support 25 watts of charging power, while the S24 Ultra stands out with 45 watts, allowing for faster charging. Only the Galaxy S24 and S24 Ultra offer wireless charging (10 watts) and reverse charging, adding additional flexibility for users with other compatible devices.
Which one is more powerful and which has the best screen?
The Galaxy S24 Ultra is positioned at the top in terms of power with its Qualcomm Snapdragon 8 Gen 3 processor, coupled with 12 GB of RAM and a storage capacity of up to 1 TB, although it does not support expansion by micro SD card. The Galaxy S24, equipped with the Samsung Exynos 2400 processor, offers 8 GB of RAM and up to 256 GB of storage, also without the possibility of expansion. The Galaxy A15, with its MediaTek Dimensity 6100+ processor, offers 4 GB of RAM and 128 GB of storage, expandable by micro SD, making it the least powerful but also the most flexible in terms of storage.
For the screens, the Galaxy S24 Ultra offers a 6.8-inch AMOLED panel with a definition of 1440×3120 pixels, a refresh rate of 120 Hz, and a maximum brightness of 2600 cd / m², offering a superior visual experience especially since it benefits from an exceptional anti-reflective treatment, far superior to all other smartphones on the plateau. In addition, it benefits from protection that is particularly resistant to shocks and scratches. The Galaxy S24 has a 6.2-inch AMOLED screen, 1080×2340 pixels, also at 120 Hz, with a maximum brightness of 2600 cd / m². The Galaxy A15, although also featuring an AMOLED display, offers a size of 6.5 inches with a definition of 1080×2340 pixels and a refresh rate of 90 Hz, with a maximum brightness of 800 cd/m², which places it behind the other two Samsung models in terms of display quality.
What configurations for photos and what connectivity?
In terms of photography, the Galaxy S24 Ultra stands out with a 200-megapixel optically stabilized main sensor, accompanied by three other sensors (12-megapixel ultra-wide-angle, 50-megapixel telephoto with 5x optical zoom, and 10-megapixel telephoto with 3x optical zoom ), and a 12-megapixel selfie sensor. The Galaxy S24 offers a 50-megapixel optically stabilized main sensor, a 12-megapixel ultra-wide-angle sensor, a 10-megapixel telephoto lens with 3x optical zoom, and a 12-megapixel selfie sensor. The more modest Galaxy A15 has a 50-megapixel main sensor, a 5-megapixel ultra-wide-angle, a 2-megapixel macro, and a 13-megapixel selfie sensor. Thus, the S24 Ultra is the ideal choice for demanding photography enthusiasts, followed by the S24 and finally the A15.
Finally, in terms of connectivity, the Galaxy S24 Ultra is the most advanced with support for Wi-Fi 7, while the Galaxy S24 supports Wi-Fi 6E and the Galaxy A15 is limited to Wi-Fi 5. All three are NFC and Bluetooth 5.3 compatible, but only the Galaxy S24 and Galaxy S24 Ultra are eSIM compatible. None of the models has an infrared transmitter, and only the jack socket is present on the Galaxy A15. Regarding waterproofing, the Galaxy S24 and Galaxy S24 Ultra benefit from IP68 certification, guaranteeing resistance to water and dust, unlike the Galaxy A15. The fingerprint readers are placed under the screen for the Galaxy S24 and Galaxy S24 Ultra models, while it is on the profile for the slightly less practical Galaxy A15.
