Do you want a Samsung smartphone from the Galaxy A series but you are hesitating between the Galaxy A05s, the Galaxy A15, the Galaxy A25, the Galaxy A35 and the Galaxy A55? Here are their main technical characteristics compared to help you see more clearly.
In terms of design, the Galaxy A05s, Galaxy A15 5G, Galaxy A25 5G, Galaxy A35 5G and Galaxy A55 5G share a minimalist and refined approach, with minute differences in the organization of the photo sensors on the back. The Galaxy A05s and A15 5G offer a sober arrangement of sensors, seemingly simply placed on the rear cover. The A25 5G and A35 5G models maintain this simplicity while introducing varied finishes and colors. The Galaxy A55 5G, on the other hand, is distinguished by a glass back and a slight domed effect on the buttons, adding a touch of elegance. Smartphone profiles are either flat or slightly rounded, with a color palette ranging from classic black to lime (lemon yellow), midnight blue and lilac.
Regarding dimensions, these smartphones have minor variations in height, width and thickness, but generally remain in a similar range, making the choice less decisive. The Galaxy A05s is the tallest (168mm) while the Galaxy A55 5G is the heaviest (213 grams), indicating a trend towards more substantial devices in recent models. Conversely, the Galaxy A15 5G, although the lightest, does not sacrifice features or performance.
Battery capacity is uniform across these models, all equipped with 5000 mAh batteries, promising good battery life. The supported charging power is identical for all devices (25 watts), without the possibility of wireless charging.
Which is the most powerful and which is the best screen?
Under the hood, each smartphone is powered by a different processor, offering a varied range of performance. The Galaxy A05s with its Snapdragon 680 is the least powerful, followed by the A15 5G and its MediaTek Dimensity 6100+ Soc. The Galaxy A25 5G and A35 5G, equipped with an Exynos 1280 and 1380 respectively, offer a notable improvement. The Galaxy A55 5G, equipped with an Exynos 1480, crowns this power hierarchy. RAM capacity and internal storage also increase with model number, providing expandable storage options via micro SD for everyone.
Analysis of the screens reveals significant differences in terms of display quality. The A15 5G, A25 5G, A35 5G and A55 5G models all benefit from AMOLED screens, known for their deep blacks and vivid colors, while the A05s stands out with an LCD screen. Screen sizes vary slightly, but all offer a 90Hz or 120Hz refresh rate for a smooth viewing experience. The peak brightness increases with more advanced models, the Galaxy A55 5G and Galaxy A35 5G standing out with its maximum brightness of 1000 cd/m² and its HDR10+ certification. The latter also benefit from significantly stronger screen protection than the others.
What configurations for photos and what connectivity?
In terms of photography, the quality of the images produced by these Samsung phones is mainly modulated here by the number of megapixels, optical stabilization (present on more high-end models) and the image processing capabilities operated by the processor. The Galaxy A55 5G, with its 50-megapixel main sensor (like the Galaxy A35 5G) and 12-megapixel ultra-wide-angle sensor as well as its 32-megapixel selfie sensor, offers the best versatility and image quality, followed by closely matched by the A35 5G and the A25 5G. The Galaxy A05s and A15 5G, although competent, are behind.
Finally, connectivity and additional features like Wi-Fi 6, NFC technology, the absence of a jack on newer models, and IP67 waterproof certification for the A35 5G and A55 5G, enrich the ecosystem of each smartphone. The placement of the fingerprint reader location varies, with a trend towards integration under the screen for an improved user experience in high-end models while it is placed on the sleep button for the Galaxy A05s, Galaxy A15 and Galaxy A25.
