Samsung Galaxy Book 4: Can the Korean notebook hold its ground in Brazil?

The Samsung Galaxy Book 4 arrived as Samsung’s bet to compete in the premium notebook segment with Intel’s 14th generation processors. It’s a machine aimed at users already living in the Samsung ecosystem, who want integration with their Galaxy phone and need a thin, lightweight notebook for professional daily use. The short answer to the title’s question: yes, it’s worth it, but with important caveats that depend directly on your usage profile and how much you’re willing to pay for the brand experience.

In Brazil, the Galaxy Book 4 faces a classic challenge: heavy taxes on imported electronics make any foreign notebook more expensive and place the product in a price range where competition is fierce. Nevertheless, Samsung’s proposal has concrete arguments, especially for those who use a Galaxy smartphone and want to take advantage of continuity features between devices, something the manufacturer has been developing consistently in recent years.

This review was built based on Samsung’s official specifications, publicly available information released by the manufacturer, and availability data in the Brazilian market. We do not claim to have tested the unit in our own laboratory.

Samsung Galaxy Book 4 Technical Specifications

Specifications may vary depending on the version sold. Confirm the exact configuration on Samsung Brazil’s official website before purchasing.

Real-World Performance: What Intel Core Ultra Delivers

The heart of the Galaxy Book 4 is the Intel Meteor Lake platform, which represents an important shift in Intel’s notebook processor architecture. Unlike previous generations, Meteor Lake uses a modular design called “tile” (think of it as Lego pieces fitting together rather than a single chip), which allows separation of performance cores, efficiency cores, and the artificial intelligence processing unit, called NPU.

The Core Ultra 7 155H, found in the more complete versions, features 16 cores and 22 threads. For office work, browsing with many tabs open, video conferencing, and light photo editing, according to Samsung’s specifications, the configuration is more than sufficient. The major leap from previous generations lies precisely in AI-heavy workloads, a point Microsoft has been pushing with Windows 11 and its Copilot features.

The integrated Intel Arc GPU can handle casual games and video editing at lower resolutions, but it wasn’t designed for heavy gaming. If gaming is your priority, the Galaxy Book 4 isn’t the right product. In that case, it’s worth checking the complete guide to notebooks under 4000 reais in 2026 to understand which alternatives deliver dedicated GPU in more accessible price ranges.

15.6-inch AMOLED Display: Strength With a Caveat

The screen is undoubtedly one of the Galaxy Book 4’s biggest selling points. The AMOLED panel (organic light-emitting diode technology that produces light from each pixel) guarantees absolute blacks and vibrant colors that conventional LCD panels simply cannot replicate. For those who consume a lot of streaming content or work with photo editing, the difference is immediately noticeable.

The downside is the 60 Hz refresh rate. Competitors in the same price range, such as notebooks with 120 Hz or 144 Hz IPS panels, deliver noticeably more fluid scrolling and animations. For standard professional use, 60 Hz isn’t a real problem, but if you’re sensitive to this difference, especially if you’re coming from a 120 Hz smartphone, the screen might feel “sluggish” at first.

The maximum brightness claimed by Samsung is adequate for indoor environments. When used outdoors in direct sunlight, visibility can drop, something common to many AMOLED panels that prioritize color quality over raw brightness. Check the nits value in the technical specifications of the specific model you plan to buy.

54 Wh Battery: Honest Autonomy, Not Exceptional

The 54 Wh battery is one of the specifications that generates the most questions in thin notebooks. For reference: notebooks with similar performance from competitors typically come with batteries between 65 Wh and 86 Wh. According to the manufacturer, estimated battery life revolves around one day of typical office use, but this figure depends heavily on the processor configuration chosen and screen brightness.

The 65 W USB-C charger is a concrete positive point. Charging via USB-C means that in many cases, you can use the same charger as your Galaxy phone or other devices, which reduces the number of accessories in your backpack. Samsung doesn’t specify the exact recharge time from 0 to 100%, but 65 W chargers on 54 Wh batteries typically complete the cycle in about 1.5 hours. Check this data in the official documentation before finalizing your evaluation.

Samsung Ecosystem Integration: The Real Differentiator

Here lies the strongest argument of the Galaxy Book 4 for Brazilian users who already own a Galaxy smartphone. The Samsung Link to Windows feature (integration with Windows 11’s Link to Windows app) allows you to mirror your phone’s screen on the notebook, reply to messages, and use Android apps directly on your PC, without cables. Samsung went further and implemented features like dragging and dropping files between phone and notebook over local network.

For those who also use Galaxy Buds earphones, the automatic connection switching between devices works smoothly, according to public user reports and international specialized publications. This integration has no equally polished equivalent on other Windows notebooks, except Microsoft’s Surface in combination with Android. If you use an iPhone, this argument loses all its appeal and the Galaxy Book 4 loses its main differentiator.

Galaxy Book 4 Pros and Cons

Pros:

• High-quality AMOLED display with vibrant colors and deep blacks
• Thin and lightweight design for a 15.6-inch machine
• 65 W USB-C charging eliminates proprietary charger
• Native integration with Samsung phones and accessories is among the best on the market
• Intel Core Ultra processor with NPU prepared for Windows 11 AI features
• Anatel approved with official Samsung Brazil warranty

Cons:

• Screen refresh rate limited to just 60 Hz in the standard version
• 54 Wh battery below what direct competitors offer
• No dedicated GPU, limiting heavy editing and gaming
• Brazilian price heavily impacted by import taxation

Competitors and Alternatives in Brazil

Prices are estimates based on values observed in the Brazilian market in 2026 and subject to variation by store, promotion, and exchange rate.

The main rival in ecosystem integration would be the LG Gram, which doesn’t have the same smartphone integration proposal. For users who prioritize battery autonomy, the Lenovo IdeaPad Slim 5 and LG Gram 16 deliver more hours away from the outlet. For those who want high-quality display in a Samsung machine, the Galaxy Book 4 truly stands apart.

Frequently Asked Questions About Samsung Galaxy Book 4

Does the Galaxy Book 4 have Anatel approval and warranty in Brazil?

Yes. Units sold officially by Samsung Brazil go through the Anatel approval process, mandatory for any device with wireless connectivity sold in the country. Samsung Brazil’s official warranty is 12 months for manufacturing defects. Buying from unauthorized resellers or importing directly may leave you without local warranty coverage.

Is it worth importing the Galaxy Book 4 from the US to save money?

Launch price in the US hovered around USD 1,099 for basic versions. Taking into account import duties, IOF on international card transactions, and possible customs fees, the actual savings typically ends up being less than it seems. Additionally, imported units may lack local technical support or valid warranty in Brazil, which is a significant risk for a product in this price range.

Can the Galaxy Book 4 run games?

Casual games and older titles, yes. Modern games with high graphics requirements, not with good performance. The integrated Intel Arc GPU wasn’t designed to replace a dedicated graphics card. If gaming is a priority, look for notebooks with dedicated NVIDIA or AMD GPU.

Does ecosystem integration work with any Android smartphone?

Basic integration via Microsoft’s Link to Windows works with any recent Android device. However, Samsung’s exclusive features, like dragging and dropping files, mirroring phone apps, and automatic Galaxy Buds connection, only work with Galaxy line smartphones. With iPhones, none of these features are available.

Is It Worth Buying the Galaxy Book 4 in Brazil?

Recommended for: users who already own a Galaxy smartphone and want to maximize integration between devices; professionals who prioritize display quality for content consumption and presentations; anyone needing a lightweight notebook with USB-C charging and without dedicated GPU demands; Windows users who want a more cohesive ecosystem experience.

Not recommended for iPhone users, those needing dedicated GPU for gaming or rendering, those prioritizing battery autonomy above all else, or those on tighter budgets who can be satisfied with alternatives like Lenovo or ASUS that deliver competitive specs for less.

Price range: between R$ 5,500 and R$ 7,500 depending on configuration, store, and timing of purchase. Confirm updated pricing on Samsung Brazil’s official website or authorized retailers before making your final decision.
