Samsung Galaxy Book 4: the right notebook for your daily use?

The Samsung Galaxy Book 4 arrived to occupy a very specific slice of the market: notebooks aimed at everyday use, with balance between performance, portability and integration with the Samsung ecosystem. Originally launched in 2024, it still circulates in Brazil in 2026 with more accessible prices than at launch, which makes the question about “is it worth it” even more relevant. The Book 4 line is broad, with 15 and 16-inch versions, plus Pro and Edge variants with higher configurations, so this review focuses on the base 15-inch model, which is the most commonly found in Brazil.

The short answer is: yes, it works well for those who need a reliable notebook for office work, studies and content consumption, without heavy demands for video editing or gaming. It’s not the most powerful notebook in its category, nor the cheapest. But it has decent build quality, good integration with Android and Windows, and a screen that pleases for general use.

If you’re switching from an iPhone to a Samsung, for example, the Book 4 can be an interesting ally in this transition, as the integration between Samsung devices makes tasks like screen mirroring and file continuity easier. Also, if you need to transfer data between platforms, it’s worth checking how to transfer WhatsApp from iPhone to Samsung in 2026, which can be useful in this ecosystem change process.

Samsung Galaxy Book 4 tech specs (15 inches)

Specifications based on Samsung’s official tech sheet. Configurations may vary depending on the version sold in Brazil.

Performance in daily use: where it shines and where it stumbles

The Intel Core 5 120U processor belongs to the Meteor Lake generation, Intel’s hybrid architecture that mixes high-performance cores and efficiency cores, similar to how a team has starters and reserves: the starters handle heavy tasks, the reserves handle light work without wasting energy. According to Intel, this combination improves energy efficiency compared to previous generations, which helps with battery life.

In practice, according to the tech sheet and widely documented reports from users abroad, the Book 4 handles typical office use well: browsing with dozens of tabs open in Chrome or Edge, spreadsheets in Excel, video conferences in Teams or Google Meet, and light document editing. With 16 GB of LPDDR5 RAM (a type of fast and energy-efficient memory), the system doesn’t choke on conventional multitasking.

The point of attention is Intel’s integrated GPU, which has no dedicated video memory. It shares the system’s RAM to process graphics. This means that 4K video editing, 3D rendering, or more demanding games are not the device’s strong suit. For those who use Premiere, DaVinci Resolve professionally or want to play AAA titles (high-budget games with intensive graphics), the Book 4 will frustrate. For everyone else, it’s more than enough.

15.6″ display: good enough, but no surprises

The Full HD 15.6-inch display with IPS panel delivers wide viewing angles, which is positive for those who use the notebook in meetings or show content to others. The 1920×1080 resolution is suitable for the screen size, without appearing grainy.

What’s missing is a bit more brightness for very bright environments and the 60 Hz refresh rate, which is standard for productivity, but can seem less fluid for those already accustomed to 90 Hz or 120 Hz displays on smartphones. For text, spreadsheets and video streaming, no one will complain. But don’t expect that color vibrancy that Samsung puts in the AMOLED displays of its top-end phones.

Samsung didn’t equip the base Book 4 with AMOLED, reserving this type of panel for the Pro and Edge models. If screen quality is a deciding factor for you, it’s worth researching the higher-end versions or the competitors listed below.

Battery and autonomy: a decent point, not exceptional

The 54 Wh battery is capable of, according to manufacturer information, delivering autonomy for a full workday under moderate use conditions. This type of statement, as usual, considers reduced brightness and lighter tasks. In more intense use, with high brightness and multiple applications open, the real battery life will be shorter.

Charging via USB-C with the adapter included in the box is convenient, but Samsung doesn’t consistently detail the maximum charging power for the base model in Brazilian spec sheets, so check this information before buying if charging speed is important to you. The good news is that the USB-C Thunderbolt 4 accepts third-party chargers, something that increases practicality in everyday use.

The weight of 1.55 kg is acceptable for a 15.6-inch notebook, placing it in a category of reasonable portability for those who carry it in a backpack daily.

Software, Samsung integration and Windows 11 experience

One of the real differentiators of the Book 4 compared to competitors from brands without their own ecosystem is the integration with Samsung devices. Samsung Link to Windows, built into Windows 11, allows you to mirror your Samsung phone’s screen on the notebook, reply to messages, and access photos without needing to pick up your phone. It works for real and is a concrete productivity gain.

Windows 11 Home comes pre-installed without aggressive customizations, which is positive. Samsung adds some of its own applications, but nothing that slows down the system or is difficult to remove. The initial setup is clean and straightforward.

An important aspect for the Brazilian market: verify that the purchased model is certified by Anatel, Brazil’s telecommunications regulatory agency. Imported notebooks without certification may have warranty and official support difficulties. Samsung Brasil sells certified versions, and local warranty is 12 months. Authorized stores usually offer faster service than the import process.

Frequently asked questions about the Samsung Galaxy Book 4

Does the Galaxy Book 4 run games?

Light games and titles from a few years ago work, but don’t expect adequate performance in modern titles with demanding graphics. The integrated Intel GPU shares the system’s RAM, which limits performance in graphics-intensive applications. For casual or older games, it’s acceptable.

Does the Book 4 have warranty in Brazil?

Yes, when purchased through official Samsung Brazil channels or authorized resellers, the notebook has a 12-month warranty in Brazil. Always check the Anatel certification on the packaging or on the Anatel website before finalizing your purchase, especially on marketplaces.

Is it worth paying more for the Galaxy Book 4 Pro?

If screen quality is a priority, yes: the Pro model brings an AMOLED panel with higher resolution, plus more powerful processors. For basic productivity use only, the base model already meets the needs, but the Pro is noticeably better for those who consume a lot of visual content or work with photo editing.

Is the Book 4 compatible with any external monitor?

Yes. The Thunderbolt 4 port and HDMI output allow you to connect external monitors. Thunderbolt 4 supports high-speed data transfer and can power 4K monitors. Check the specifications of the monitor you intend to use to ensure compatibility, especially regarding the maximum supported resolution.

Is it worth buying the Galaxy Book 4?

The Galaxy Book 4 is an honest notebook. It doesn’t try to be what it’s not and delivers well what it promises: a computer for the daily use of students, office professionals and those who want a second device integrated into the Samsung ecosystem. The real differentiator is the integration with Samsung phones and the careful software experience, which makes a difference especially for those who already use other Samsung products, like smartwatches or Galaxy earbuds. By the way, if you’re also building a wearable ecosystem, it might be worth comparing options like the Galaxy Fit 3 or Xiaomi Smart Band 10 to complement the Samsung experience.

Recommended for: university students, professionals who work mainly with spreadsheets, presentations and video conferences, Samsung ecosystem users who want native integration between notebook and phone, and those looking for a notebook with plenty of ports and without needing a dedicated graphics card.

It’s not the right choice for content creators who edit video professionally, gamers, or those who want the best raw hardware value for money without caring about brand or ecosystem.

Price range: between R$ 3,500 and R$ 4,500 in Brazil in 2026, with variations depending on the store and promotions. The launch price in the US in 2024 was approximately US$ 699 for the base configuration. If imported, consider the cost of internationalization and the lack of local warranty.
