Samsung Galaxy S25: review, key features, interesting features

The Samsung Galaxy S25 series is a logical development of the flagship line of 2025. It combines familiar design with advanced hardware solutions and software capabilities. Let's take a look at the technical specifications of the main models, their key features, and evaluate their advantages and disadvantages.

Design and build

Samsung has retained the familiar body style, improving ergonomics and making the models thinner and lighter. This is especially noticeable in the base S25 — the device has become more compact compared to last year's S24.

All devices feature premium materials: aluminum and Gorilla Glass Victus 2 in the S25/S25+, titanium and Gorilla Glass Armor 2 in the Ultra, and a titanium body and ceramic glass in the Edge.

Hardware platform and display

At the heart of all models is the Snapdragon 8 Elite for Galaxy — a powerful 3nm chip with 12GB of RAM in the base configurations.

The standard S25 has a 6.2“ Dynamic AMOLED 2X display with FHD+, 1-120 Hz, and brightness up to 2600 nits. The higher-end models have 6.7” and 6.9" screens, respectively, with QHD+ and the same brightness.

Display specifications

• Dynamic LTPO AMOLED 2X with an adaptive refresh rate from 1 to 120 Hz.
• Maximum brightness up to 2600 nits and HDR10+ support.
• Protection — Gorilla Glass Victus 2 or Armor 2 (in Ultra), and ceramic glass is used in Edge.

The device shows excellent detail and brightness, and the refresh rate ensures a smooth interface and adaptation to tasks.

Cameras and multimedia

The base model S25 has a triple camera: 50 MP wide angle, 10 MP telephoto (3× zoom), and 12 MP ultra-wide.

The S25 Ultra offers an impressive set: 200 MP main, 50 MP periscope (5×), 10 MP telephoto (3×), and 50 MP ultra-wide lens.

• The front camera is the same for all models: 12 MP, 4K video.
• The Ultra and Plus offer advanced AI processing capabilities and HDR 10-bit video recording.

The overall camera rating is high, especially for the Ultra: daytime and nighttime shooting produce detailed images. However, the base model has not received any significant updates compared to the previous generation.

Battery life and charging

The base S25 is equipped with a 4000 mAh battery with 25W charging, the Plus has a 4900 mAh battery with 45W charging, the Ultra has a 5000 mAh battery with 45W charging, and the Edge has a 3900 mAh battery with 25W charging.

• All models support Qi2 wireless charging up to 15W and reverse charging up to 4.5W.
• The Edge lost battery capacity for the sake of an ultra-thin body.
• With active use, the battery lasts for one and a half to two days, except for excessive loads.

Despite sufficient autonomy, the S25 and Edge are slightly weaker than their competitors, especially in games and video consumption.

Software and AI

All devices run on Android 15 with One UI 7. Samsung guarantees 7 years of OS and security updates.

The key theme is the integration of Galaxy AI and Google Gemini: a “personal AI concierge” feature, improved video processing tools, task automation, and a user-friendly interface.

• Automatic processing of 10-bit HDR video and Audio Eraser.
• Intelligent context recognition and integration with applications.
• Overall performance increase of up to 40% for the Intel Neural Processing Unit AI processor.

The main drawback is that the current AI features are not always stable, require refinement, and need time to reach their full potential.

Features of the series models

The S25 series includes four models: S25, S25+, S25 Ultra, and S25 Edge. Each is geared toward its own audience, from compactness to maximum functionality and power.

• Edge is record-breakingly thin (5.8 mm), light, and stylish, but with a smaller battery and no TV.
• The Ultra is the flagship for photography enthusiasts and business tasks, with an S Pen (without Bluetooth functionality), powerful cameras, and a large screen.
• The S25 and S25+ are the optimal solution: a balance of size, power, and price.

Overall, the lineup is well structured: there is an option for everyone, depending on their priorities — size, camera, design, or battery life.

Final opinion

The Samsung Galaxy S25 is a confident evolutionary development of the S24. All models have received a powerful chip, high-quality displays, extended support, and advanced AI capabilities.

The main limitations are related to the battery life of the base models, the stability of AI functions, and the compromises of the slim design in the Edge. Nevertheless, the devices remain strong competitors in the Android flagship market.
