Samsung Galaxy S21 Review

What You Need to Know Before Buying the Samsung Galaxy S21

Introduction

The Samsung Galaxy S21, launched in early 2021, marks a bold evolution of the brand’s flagship series, bringing refined design, cutting-edge performance, and notable sacrifices to the forefront. While it retains the signature 6.2-inch FHD+ Dynamic AMOLED 2X display with a 120Hz adaptive refresh rate, which offers buttery-smooth scrolling and a visually immersive experience, the S21’s display is notably optimized for both color accuracy and power efficiency. This means users get an exceptional visual experience with vibrant, deep contrasts while maintaining fluid performance, whether it’s for media consumption, gaming, or productivity. The 120Hz refresh rate intelligently adapts based on the content being displayed, offering smoother interactions without overburdening the battery, a balanced approach compared to its predecessor.

Under the hood, the Galaxy S21 is powered by the Exynos 2100 (or Snapdragon 888 in select regions), built on a 5nm architecture that delivers significant gains in processing power and efficiency. With 8GB of RAM and 128GB or 256GB of internal storage (unfortunately non-expandable), the S21 delivers snappy performance across the board, from multitasking to gaming at the highest settings. The device also supports 5G connectivity, ensuring future-proofing in an increasingly connected world, with super-fast download speeds for users in compatible regions.

The camera system is another highlight of the Galaxy S21, featuring a 12MP wide sensor, a 12MP ultra-wide lens, and a 64MP telephoto lens with 3x hybrid zoom. The result is a versatile array of photographic options, from ultra-wide landscape shots to detailed telephoto close-ups. While the 64MP telephoto sensor offers excellent 3x optical zoom performance, the lack of a dedicated periscope lens means that its zooming capabilities fall short in comparison to the more advanced S21 Ultra. That said, the S21 still excels in everyday photography with its improved night mode, vibrant color reproduction, and powerful 8K video recording capabilities, which have redefined mobile videography.

However, Samsung made a few notable trade-offs in the S21, primarily to drive its pricing lower than its predecessor. The most significant of these is the switch from a glass back to a plastic rear panel, which, while still premium in feel, lacks the luxurious quality that many premium flagship users expect. This decision, though helping to reduce weight and enhance durability, does make the S21 feel slightly less refined when compared to its glass-bodied competitors. Another drawback is the absence of a microSD card slot, a feature once beloved by Galaxy fans for expandable storage. This exclusion, alongside the phone's non-removable battery, limits storage flexibility, a notable inconvenience in a world where apps, games, and multimedia files are growing ever larger.

Battery life, while improved with adaptive power management, remains a key point of contention. The 4000mAh battery provides a full day of use under moderate conditions, but power-hungry tasks like 120Hz gaming, video streaming, and 5G use can lead to quicker drain, making it essential for users to charge throughout the day if using these features regularly. Additionally, Samsung’s decision to exclude a charger from the box, a controversial move in an industry that's trending towards sustainability, means users must either use an existing charger or purchase one separately.

In conclusion, the Samsung Galaxy S21 is a powerhouse in terms of performance, offering impressive specs, camera capabilities, and an unparalleled display. Yet, its design choices, such as the plastic back and removal of certain features like expandable storage, do raise questions for those who expect a more premium, versatile experience from a flagship device. For users looking for a more affordable alternative to the S21 Ultra without sacrificing core features, the Galaxy S21 stands as a powerful, albeit slightly imperfect, option in the premium smartphone space. Its balanced blend of high-end performance, great display quality, and strong camera setup make it an excellent choice for most users, but the lack of key features and battery limitations could be a dealbreaker for others.

The 8GB of RAM in the Galaxy S21 ensures smooth multitasking, with the phone easily handling a combination of apps, games, and media without noticeable slowdowns. Apps load quickly, and switching between tasks feels almost instantaneous. The 120Hz Dynamic AMOLED 2X display further enhances the performance experience, providing a fluid and responsive touch interface. The high refresh rate makes scrolling, animations, and gameplay feel incredibly smooth, with minimal motion blur. The FHD+ resolution ensures crisp visuals that are sharp and clear, contributing to a premium feel during media consumption.

When it comes to gaming performance, the S21 handles most titles with ease. Popular mobile games like PUBG Mobile and Genshin Impact run smoothly at high settings, though, under prolonged gaming sessions, the Exynos 2100 may experience more noticeable heat build-up, leading to a slight dip in performance compared to the Snapdragon 888 variant. This thermal limitation is less of an issue with day-to-day tasks but can affect sustained high-performance scenarios.

The internal storage options (128GB and 256GB) are fast and provide ample space for most users, but the lack of an expandable storage option can be a limiting factor for power users or those who store large amounts of data locally, such as 4K videos or extensive media libraries. Moreover, the absence of a microSD card slot could push those looking for flexibility in storage management toward other devices that offer expandability.

In terms of battery performance, the Galaxy S21 comes with a 4000mAh battery, which is sufficient for a full day of moderate use, including social media, video streaming, and web browsing. However, under heavy usage—especially with high screen brightness and demanding apps—the battery may require a midday top-up. The 25W fast charging capability provides a quick recharge, while wireless charging and PowerShare offer convenient alternatives for charging accessories or other devices.

Overall, the performance of the Galaxy S21 is stellar for most use cases, excelling in everyday tasks, gaming, and media consumption.

One of the most notable omissions in the Galaxy S21 is the removal of the microSD card slot. For users who value expandable storage, this is a significant drawback. While the base model offers 128GB of storage, power users who store large amounts of media, apps, or files may find themselves needing more. The lack of expandable storage is a move toward streamlining the device, but it could alienate users who are accustomed to the flexibility Samsung’s previous phones provided.

2. Plastic Back Panel

While the plastic rear panel of the S21 helps reduce costs and makes the phone lighter, it does feel a bit less premium compared to the glass backs found on its predecessors, like the Galaxy S20. Some users may feel that this choice undermines the overall luxury feel of the phone, especially at its price point. However, the plastic does offer more durability, reducing the likelihood of cracking if dropped, which is a trade-off worth considering.

3. No Headphone Jack

Another drawback for some users is the lack of a 3.5mm headphone jack. While Samsung had already started phasing this out with previous models, its absence in the S21 might still be a deal-breaker for audiophiles or anyone who prefers using wired headphones. The solution for this, of course, is wireless headphones or using a USB-C-to-headphone adapter, but this still feels like a step backward for some.

4. No Charger in the Box

Following a trend set by Apple, Samsung has also chosen to remove the charger from the box. This means that you’ll have to buy one separately if you don’t already have a compatible USB-C charger. While this decision is meant to reduce e-waste, it’s still a downside for users who were expecting a complete out-of-the-box experience.

5. Average Battery Life

If you’re a heavy user, you may find yourself reaching for the charger earlier than expected, especially with the 120Hz refresh rate enabled. Battery optimization could have been better, especially considering the phone's price.

6. Limited Design Choices

While the Galaxy S21 has an attractive design, it does not offer as much customization as some of its competitors. For example, there are fewer premium materials used compared to the S21 Ultra, which features a glass back. Additionally, although the phone is available in multiple colors, the design is somewhat conservative and may not stand out as much compared to more radical designs from other brands.

7. Limited Zoom Capabilities

Although the S21 has a solid 3x hybrid zoom, it falls behind in terms of zoom performance compared to the S21 Ultra or even the iPhone 12 Pro Max. The lack of optical zoom beyond 3x may limit users who prioritize long-range photography. While the digital zoom can go up to 30x, the quality at higher zoom levels isn’t comparable to that of more expensive devices in the market.

In summary, The Samsung Galaxy S21 is a fantastic flagship smartphone that delivers on its promise of high-end performance, camera quality, and display brilliance at a competitive price point. Its sleek design, powerful specs, and seamless integration into Samsung’s broader ecosystem make it a solid choice for many users. However, the lack of expandable storage, the plastic back, and the removal of the headphone jack might be deal-breakers for some. For those looking for cutting-edge technology at a slightly lower price than its competitors, the Galaxy S21 is an excellent option, though it may not be the perfect fit for everyone. Ultimately, its strengths far outweigh its weaknesses, but whether it's the right choice depends on your specific needs and preferences.

Is the Samsung Galaxy S21 Still Worth Buying in 2024?

The Samsung Galaxy S21 is positioned as a premium flagship device, yet it is more affordable than some of its higher-end competitors, such as the Galaxy S21 Ultra and Apple’s iPhone 13 Pro. At launch, the Galaxy S21 started at $799 USD for the base model with 128GB of internal storage, offering a competitive price point for a smartphone of its caliber. The 256GB version typically costs around $849 USD, providing an additional storage option for users who need more space for apps, media, and photos. In comparison to its immediate rivals, the S21 offers a compelling value, especially considering its high-end features like the 120Hz Dynamic AMOLED display, flagship-grade performance, and versatile camera system. While the price of the Galaxy S21 may vary depending on promotions, sales, or trade-in offers, Samsung frequently provides discounts or bundles, making it an attractive option for users looking to get a premium smartphone without breaking the bank. Additionally, Samsung's annual trade-in programs allow customers to offset the price further by exchanging older devices. In many markets, the Galaxy S21 is priced competitively against similar flagship models, such as the Apple iPhone 12 and Google Pixel 6, positioning it as a great value in the premium segment. For those looking for a more budget-friendly alternative, the Galaxy S21 FE (Fan Edition) is expected to offer similar features at a slightly reduced price, making the Galaxy S series accessible to a broader audience.

Evolution from Previous Models

The Samsung Galaxy S21 represents a significant evolution from its predecessors in the Galaxy S series, building on the strengths of earlier models while introducing several exciting improvements. Compared to the Galaxy S20, which was already a standout with its 120Hz display and 5G connectivity, the Galaxy S21 refines the design and performance for an even more streamlined experience. One of the most noticeable changes is the shift to a more compact, sleek design with a plastic back (instead of the glass rear panel on the S20), which reduces weight and improves durability without sacrificing the premium feel. While the Galaxy S20 had a 120Hz display, the S21’s Dynamic AMOLED 2X offers a brighter and more power-efficient screen, enhancing outdoor visibility and battery life.

The camera system has also evolved—though both the S20 and S21 feature triple-camera setups, the S21’s 64MP telephoto lens and enhanced image processing software deliver sharper and more vibrant photos, especially in low light, thanks to improvements in sensor technology and AI-powered enhancements. Another key upgrade is the performance. The Exynos 2100 (or Snapdragon 888 in some regions) chipset in the S21 offers a significant leap in speed, efficiency, and gaming performance compared to the S20’s Exynos 990/Snapdragon 865. Plus, with 8GB of RAM standard across all models, multitasking and app switching is even smoother than before.

Pricing also saw a shift. Samsung made the S21 more affordable than the S20, cutting down on the entry-level cost by offering a more competitive base price without compromising on essential features, making it a better value proposition for consumers who want flagship performance without the premium price tag of the S20 Ultra or iPhone 12 Pro. In short, the Galaxy S21 takes the lessons learned from the S20 and refines them into a more polished, efficient, and cost-effective flagship, making it a great upgrade for those looking for the latest in mobile technology.

Key Decision-Making Factors

When considering whether the Samsung Galaxy S21 is the right phone for you, there are a few key decision-making factors to keep in mind. First, think about your budget—the S21 offers excellent value for its price, with flagship features like a 120Hz display, 5G connectivity, and powerful performance, all at a more affordable rate than some of its competitors. If you're looking for premium design and display quality, the Galaxy S21’s Dynamic AMOLED 2X screen is one of the best in the market, delivering vibrant colors and smooth visuals that make everything from gaming to media consumption a pleasure. Another important factor is camera performance. With its versatile triple-camera setup and enhanced low-light capabilities, the S21 is perfect for users who enjoy photography or want to capture high-quality videos. Additionally, the processor performance is top-notch, so if you’re someone who values speed, multitasking, and gaming performance, the S21’s Exynos 2100 (or Snapdragon 888) chip will easily handle everything you throw at it. However, if you're someone who needs expandable storage or a premium glass build, you might miss those features, as the S21 opts for a plastic back and lacks a microSD card slot. Lastly, consider battery life—while the S21’s 4,000mAh battery gets you through a day of normal use, it’s not the longest-lasting phone, so if heavy usage is a concern, you might want to check other options or take advantage of fast charging features. Ultimately, the S21 is an excellent choice if you're looking for a well-rounded, high-performing smartphone at a competitive price, but these factors will help you decide if it's the right fit for your specific needs.

Conclusion

In conclusion, the Samsung Galaxy S21 offers a sophisticated balance of performance, design, and technological innovation that makes it a standout in the crowded premium smartphone market. From a feature perspective, it’s equipped with a stunning Dynamic AMOLED 2X display, delivering exceptional brightness and color accuracy, making it perfect for media consumption and gaming. The device’s powerful Exynos 2100 or Snapdragon 888 (depending on the region) provides fast, responsive performance, ensuring smooth multitasking and gaming experiences. Coupled with its capable camera system, which excels in both low-light conditions and video recording, the Galaxy S21 offers versatile imaging options for all types of users.

The device’s market positioning places it just below the ultra-premium S21 Ultra, making it an attractive choice for those who want flagship-level features without the higher price tag. When compared to competitors like the iPhone 13 and Google Pixel 6, the S21 shines in areas like display quality, 5G support, and a more expansive selection of features at a lower price point. However, it’s not without its compromises—Samsung's decision to omit expandable storage and the removal of the charger from the box might not sit well with everyone.

From an evolutionary standpoint, the Galaxy S21 represents a step forward from its predecessor, the S20, with more refined design choices, faster performance, and a focus on the next-gen 5G technology. The S21's improved camera software and hardware integration also reflect Samsung's continuous refinement of its imaging capabilities, pushing it further ahead of competitors in certain use cases.

When considering its strengths and weaknesses, the S21 excels in performance, display quality, and camera versatility, but it falls short with the lack of microSD support and some may find its battery life not as competitive as some other flagship models. The price range of the Galaxy S21 positions it as an excellent value for those looking for premium specifications without the premium price tag of the S21 Ultra or iPhone 13 Pro Max. Ultimately, the S21 is a great choice for anyone seeking a top-tier Android smartphone that delivers cutting-edge technology, without breaking the bank—perfect for those upgrading from previous models or entering the premium smartphone market for the first time.
