Samsung’s 2025 Galaxy Line up: AI-powered S25 flagships and next-generation foldables

Samsung’s 2025 smartphone family takes a two‑pronged approach: the Galaxy S25 series pushes the traditional candy‑bar form factor to new heights with AI‑centric features and high‑resolution cameras, while the foldable Galaxy Z Fold7 and Z Flip7 showcase the company’s most advanced flexible displays. Announced in January and July 2025 respectively, these devices introduce the Exynos 2500 and Snapdragon 8 Elite chipsets tailored for Galaxy AI, improved screens with up to 120 Hz refresh rates, larger batteries and refined designs. Below, we break down each model’s standout features and compare their specifications.

Galaxy S25 Series – AI companion for traditional form factors

Samsung markets the Galaxy S25 family as its first “true AI companion.” The phones run One UI 7 on Android 15 and use a customized Snapdragon 8 Elite mobile platform with on‑device AI acceleration. New multimodal AI agents process text, voice, images and video to enable context‑aware actions (for example, Circle to Search now recognizes phone numbers, emails or URLs on the screen and offers one‑tap actions). Privacy features such as an on‑device personal‑data engine and post‑quantum cryptography ensure that these AI experiences remain secure.

Galaxy S25 Ultra

The Galaxy S25 Ultra is Samsung’s top bar‑shaped phone. It features a 6.9‑inch QHD⁺ Dynamic AMOLED 2X display with a 1–120 Hz adaptive refresh and Vision Booster to improve outdoor visibility. The aluminium and glass chassis measures 77.6 × 162.8 × 8.2 mm and weighs 218 g. A quadruple rear camera system combines a 50 MP ultra‑wide, 200 MP wide, 50 MP telephoto with 5× optical zoom and 10 MP telephoto with 3× optical zoom; a 12 MP front camera handles selfies. Memory configurations start at 12 GB RAM with 256 GB storage and scale up to 1 TB. A 5,000 mAh battery supports 65 % charge in roughly 30 minutes with a 45 W adapter, alongside fast wireless charging and Wireless PowerShare for accessories. It offers IP68 water/dust resistance and includes 5 G, LTE and Wi‑Fi 7 connectivity.

Galaxy S25 and S25⁺

The standard Galaxy S25 and larger S25⁺ share many traits with the Ultra but offer more compact designs. The S25 uses a 6.2‑inch FHD⁺ screen while the S25⁺ steps up to 6.7‑inch QHD⁺; both panels are Dynamic AMOLED 2X with 1–120 Hz refresh, Vision Booster and Adaptive Color Tone. The S25 measures 70.5 × 146.9 × 7.2 mm and weighs 162 g, whereas the S25⁺ is slightly larger at 75.8 × 158.4 × 7.3 mm and weighs 190 g. Each model has a triple rear camera array: 12 MP ultra‑wide, 50 MP wide and 10 MP telephoto (3×), plus a 12 MP front camera. Both phones pair 12 GB of RAM with storage options ranging from 128 GB to 512 GB. Battery capacities are 4,000 mAh (S25) and 4,900 mAh (S25⁺); they can charge to 50 % in about 30 minutes with a 25 W adapter or 65 % with a 45 W adapter. Like the Ultra, they are rated IP68 and support Wi‑Fi 7 and 5 G.

S25 series at a glance

The table below summarizes the key specifications for the S25 models. All three devices offer high‑refresh displays, large batteries and AI‑enhanced cameras; the Ultra stands out with its 200 MP main sensor and larger QHD⁺ screen.

Galaxy Z Fold7 – Samsung’s flagship foldable

Launched in July 2025, the Galaxy Z Fold7 refines Samsung’s book‑style foldable. It introduces a thinner hinge, improved durability with Corning Gorilla Glass Ceramic 2 and Victus 2, and IP48 water‑resistance certification. The phone unfolds to reveal an 8‑inch QXGA⁺ Dynamic AMOLED 2X main display and a 6.5‑inch FHD⁺ cover screen, both supporting 1–120 Hz adaptive refresh rates. Despite its large screen, it remains surprisingly portable at 72.8 × 158.4 × 8.9 mm folded and 215 g.

The Z Fold7’s triple‑camera system features a 200 MP wide‑angle sensor, 12 MP ultra‑wide and 10 MP telephoto (3× optical zoom), complemented by a 10 MP front camera and a 10 MP cover selfie camera. Samsung pairs these cameras with AI‑powered editing features and “Space Zoom” up to 30×. Under the hood is Qualcomm’s Snapdragon 8 Elite for Galaxy, 16 GB or 12 GB of RAM, and storage options up to 1 TB. A 4,400 mAh dual battery supports 50 % charge in about 30 minutes via 25 W wired charging along with fast wireless charging and Wireless PowerShare. The device ships with Android 16 / One UI 8 and connects over 5 G, LTE and Wi‑Fi 7.

Galaxy Z Flip7 – Pocket‑sized power with a bigger cover screen

The clamshell Galaxy Z Flip7 brings a larger, edge‑to‑edge 4.1‑inch FlexWindow on the exterior and a 6.9‑inch main display inside, both using Dynamic AMOLED 2X panels with a 120 Hz refresh rate. At 13.7 mm thin when folded, 6.5 mm when unfolded and 188 g, it is Samsung’s slimmest flip phone yet. The cover and back use Gorilla Glass Victus 2, while a restructured Armor Flex Hinge and Armor Aluminium frame improve durability.

The Z Flip7’s rear camera system includes a 12 MP ultra‑wide and a 50 MP wide‑angle lens; the 10 MP front camera sits within the main screen. The phone runs on Samsung’s Exynos 2500 processor with 12 GB of RAM and offers 256 GB or 512 GB of storage. A 4,300 mAh dual battery delivers up to 31 hours of video playback and supports 25 W wired fast charging (50 % charge in around 30 minutes) plus Fast Wireless Charging 2.0 and Wireless PowerShare. The device ships with Android 16 / One UI 8 and includes Wi‑Fi 7, Bluetooth 5.4 and IP48 water resistance.

Conclusion – Choosing the right Galaxy

Samsung’s 2025 line‑up demonstrates the company’s dual strategy: maintain traditional bar‑shaped flagships while pushing the limits of foldable technology. The S25 series offers three sizes with consistent performance, long battery life and AI‑enhanced photography. Power users will gravitate toward the S25 Ultra for its 200 MP camera and S Pen support, while the S25 and S25⁺ deliver flagship features in more pocket‑friendly packages. For those seeking something different, the Z Fold7 offers the largest canvas for productivity and multitasking, whereas the compact Z Flip7 provides flagship‑level performance and a fun, pocketable design. Across the board, Samsung’s integration of Galaxy AI and next‑generation hardware signals a step forward in personalized, context‑aware smartphones.
