TechRadar reviewed the Samsung Galaxy S21 Plus as a powerful phone but an "awkward middle child," recommending the standard S21 or the S21 Ultra instead. Pros include a premium matte glass design, a 6.7-inch 120Hz AMOLED display, and strong performance and battery life, while cons include a reduced Full HD+ resolution, no microSD slot, the exclusion of a charger, and largely unchanged camera hardware from its predecessor.
SamMobile’s review describes the Samsung Galaxy S21+ as a refined "middle child" offering a premium, matte Gorilla Glass Victus back and a distinctive "Contour Cut" camera design. The device features a 6.7-inch Dynamic AMOLED 2X display with an adaptive 120Hz refresh rate, though a noted downgrade is the reduction to FHD+ resolution. Performance is handled by the efficient Exynos 2100/Snapdragon 888, and the shift to a flat screen is lauded for usability. Key pros include the striking design, smooth display, and improved, snappy performance. Conversely, cons feature the lower resolution, removal of the microSD slot, lack of in-box accessories, and mostly stagnant camera hardware compared to the S20+. Despite these, the 4,800mAh battery provides solid, if not exceptional, endurance. Ultimately, the S21+ is positioned as a well-rounded flagship for users prioritizing a large display and modern design without paying for the Ultra model. It is considered a strong, "money well spent" option for those looking to upgrade from older devices. For more details, visit SamMobile. SamMobile
The Samsung Galaxy S21 Plus acts as a premium "sweet spot" in the S21 lineup, featuring a 6.7-inch 120Hz AMOLED display and a redesigned "Contour Cut" camera housing. Key advantages include a durable metal-and-glass construction, a long-lasting 4,800mAh battery, and a significantly improved, faster in-display fingerprint sensor. Despite these strengths, the device is criticized for lacking innovation compared to the S20 Plus, removing the microSD slot and charger, and downgrading the screen to FHD+ resolution.
The DXOMARK review of the Samsung Galaxy S21+ 5G (Exynos) indicates that the device, equipped with a 12 MP main sensor, 12 MP ultra-wide, and a 64 MP telephoto lens, provides a satisfying photography experience that mirrors the performance of the smaller standard S21 model. Strengths include accurate target exposure, neutral white balance, and an effective bokeh mode for portraits, alongside a wide dynamic range in video. However, the device shows high noise levels, a lack of fine detail in zoom shots, and, in some cases, dull colors in video. While a solid choice for general photography, the camera's noise-to-detail balance is less refined compared to top-tier competitors.
The Samsung Galaxy S21 Plus is positioned as a capable, large-screen device featuring a 6.7-inch 120Hz AMOLED display and a polished "contour cut" design, though it compromises with a lower 1080p resolution compared to previous models. While offering high-end performance via the Snapdragon 888 or Exynos 2100 chipset, it occupies an awkward middle ground between the standard S21 and the more advanced Ultra model. Key pros include the display quality and solid battery life, while cons focus on the high price point, lack of a microSD card slot, and absence of a charger in the box.
The Samsung Galaxy S21 Plus stands out as a balanced, ergonomic "middle child" in the 2021 lineup, featuring a premium matte glass back and a comfortable, lighter design compared to the S21 Ultra. Performance is driven by the Snapdragon 888 processor, supported by a fast, flat 1080p OLED screen and a reliable 4,800mAh battery, making it a top contender for daily use. Key cons include the removal of the microSD card slot, slower 25W charging, and a, camera system that relies on a hybrid rather than true optical telephoto zoom.
The Tom’s Guide review positions the Samsung Galaxy S21 Plus as a premium, large-screen device featuring a durable "contour cut" design, a bright 120Hz 6.7-inch AMOLED display, and strong performance from the Snapdragon 888 chipset. While the camera system is capable, a notable drawback is that the hardware lacks significant upgrades over its predecessor, alongside a reduced 1080p screen resolution and the removal of both a microSD card slot and charger in the box. Despite these cons, the phone offers good battery life, fast charging, and long-term software support, though its $999 launch price makes it a less compelling value compared to the base S21.

Cons include average battery life of around 30 hours, less than the previous model, and cost-saving measures such as a plastic back, removal of the microSD card slot, and exclusion of an in-box charging adapter. While the rear camera system is rated "Very Good", its still and video image quality was slightly outscored by the iPhone 12 Pro. For more details, visit Consumer Reports.
Digital Trends reviewed the Samsung Galaxy S21 Plus, highlighting its premium design, smooth 120Hz AMOLED display, and strong performance powered by the Snapdragon 888 or Exynos 2100 processor. A key advantage noted was the 4,800mAh battery providing significant usage time, though the phone was criticized for camera inconsistencies between lenses and zoom limitations. The review concluded the S21 Plus is a "good" but not "groundbreaking" device, positioned awkwardly between its siblings with cons including a slippery build, lack of a microSD slot, and a high initial price.
According to Android Authority, the Samsung Galaxy S21 Plus serves as a middle-ground device offering premium performance with some compromises. Its pros include a high-quality 6.7-inch AMOLED display with a 120Hz adaptive refresh rate, next-gen performance from its 5nm chipset, and a durable build with Gorilla Glass Victus. Cons noted are a downgraded FHD+ display resolution, removal of the microSD card slot, largely unchanged camera hardware from the S20 Plus, and the absence of a charger in the box and a headphone jack. The review concludes that while the S21 Plus is a capable device, it occupies an awkward position between the S21 Ultra and the standard S21, feeling like a modest update rather than a major leap.
According to a review, the Samsung Galaxy S21+ is presented as a "middle-child" flagship with a large 6.7-inch AMOLED display and a 120Hz refresh rate, offering excellent performance but with a lower resolution than previous models. While the camera provides vibrant images, its 3x hybrid zoom is noted as less capable than rivals or the S21 Ultra, and the phone lacks a headphone jack and microSD slot. The review highlights pros such as long battery life, 5G support, and refined software, concluding that while a "hard sell" at full price, it offers better value at discounted rates.
The watson.ch review characterizes the Samsung Galaxy S21 Ultra and S21+ as significant, high-quality updates featuring refined designs and aggressive pricing. The S21 Ultra is highlighted for its premium matte glass, enhanced 108MP camera, and superior 120Hz display, while the S21+ moves to a practical flat screen design. Key cons for both devices include the removal of chargers, headphones, and microSD slots, with the Ultra being criticized for its heavy weight and the Plus for limited upgrades over the base model.
The Samsung Galaxy S21 Plus is positioned as a high-performance "middle child" in the series, featuring a flat 6.7-inch display with a 120Hz adaptive refresh rate. It is noted for its premium feel, particularly with the matte finish that resists fingerprints, according to the test. While performance is top-tier, the screen resolution is capped at Full HD+. Key performance aspects include the fast Snapdragon 888/Exynos 2100 chipset and a versatile triple-camera system featuring improved low-light performance. Battery life is robust, lasting through a full day of heavy usage, which is a major positive for the device. However, the S21 Plus faces criticism for omitting a microSD card slot and removing the charger and headphones from the box. Additionally, some reviewers consider it a minor "sidegrade" over the S20 Plus, offering few compelling upgrades for existing owners.
The Journal du Geek review characterizes the Samsung Galaxy S21 and S21+ as balanced, "flawless" flagships featuring a refined "Contour Cut" camera design, with the S21 featuring a durable "Glasstic" back and the S21+ using Gorilla Glass Victus. Performance is top-tier thanks to the Exynos 2100, paired with excellent 120Hz Dynamic AMOLED 2X displays, although the resolution is lowered to Full HD+. While the camera system delivers consistent results with improved video features, the devices lack a microSD slot and exclude chargers and headphones from the box. Journal du Geek
The 01net review characterizes the Samsung Galaxy S21+ as an excellent yet disappointing device, noting it feels less premium than the S20+ due to cost-cutting measures. Key strengths include a high-quality 120Hz AMOLED display, a stylish matte design, superior Exynos 2100 performance, and solid battery life. However, the, review highlights significant drawbacks, including a reduced 1080p screen resolution, the removal of the microSD slot, no included charger, and minimal camera upgrades.
The Samsung Galaxy S21+ is a refined flagship featuring a high-quality 6.7-inch 120Hz flat display, a durable glass-metal design with a "Contour Cut" camera housing, and strong performance from the Exynos 2100 chipset. Key pros include an excellent, responsive screen, improved build quality, fast performance, and a long-term software update commitment. However, the device sacrifices resolution (FHD+), removes the microSD card slot, lacks a charger in the box, and features only 25W charging. The triple camera system provides versatile, reliable shooting, featuring a 12MP main, 12MP ultra-wide, and a 64MP telephoto lens that enables a solid, albeit hybrid, 3x zoom. Noteworthy features include the "Director's View" and improved zoom stabilization, although the hardware is largely an incremental upgrade over the previous generation and lacks the advanced capabilities of the S21 Ultra.
The Clubic review describes the Samsung Galaxy S21 as a refined, high-quality device that adopts a strategic, more affordable approach through cost-cutting measures like a plastic back and a 1080p flat display. Performance is lauded as a key strength, with the Exynos 2100 offering a smooth, fast experience combined with a high-quality 120Hz AMOLED screen. While the camera benefits from enhanced software features like Director's View, drawbacks include mediocre battery life, the removal of the microSD slot, and the absence of a charger in the box.
The Samsung Galaxy S21, reviewed by Les Numériques, adopts a more compact design with a plastic back and the distinct "Contour Cut" camera housing. It features a high-quality 6.2-inch 120Hz AMOLED screen, though resolution is reduced to FHD+. Performance is boosted by the Exynos 2100, ensuring high fluidity, but the 4,000 mAh battery offers only average, sometimes limited, endurance. The camera system, while similar to the S20, provides excellent, versatile results, enhanced by improved software processing and features like Director's View. Key limitations include the lack of a microSD slot, no charger in the box, and the switch to a polycarbonate back, which feels less premium. Ultimately, the S21 is a compact, powerful flagship that makes some concessions in build materials and battery life to reach a lower price point. It remains highly recommended for those seeking a smaller Android device without compromising on performance.
The Samsung Galaxy S21+ features a distinct "Contour Cut" design, utilizing a matte Gorilla Glass Victus back for a premium feel. While its 6.7-inch display is praised for its 120Hz refresh rate and high brightness, the downgrade to FHD+ resolution and the omission of a microSD slot are notable cons. Performance is exceptional with the Exynos 2100, and the 4,800 mAh battery delivers strong, all-day performance.
In his review, Andrea Galeazzi describes the Samsung Galaxy S21 Plus as a well-built 'middle child' featuring a 6.7-inch Dynamic AMOLED 2X display with a 120Hz refresh rate and high brightness, though it is limited to a Full HD+ resolution. Pros include a premium glass and aluminum build, excellent display, and solid battery life, while significant cons include the absence of a charger in the box, no microSD slot, and the lack of a 3.5mm headphone jack. Powered by the Exynos 2100, the device delivers fast performance, though it may heat up under heavy stress, such as 4K video recording or gaming. The 4,800mAh battery is a notable strength, comfortably lasting through a full day of heavy use, while the camera system offers good results for most users, despite the lack of true optical zoom. Galeazzi concludes that the S21 Plus offers solid, IP68-rated, waterproof performance but is difficult to recommend over the standard S21 given the nearly identical specifications and higher price point. It is viewed as a compromise device for those seeking a larger display and better battery...
The Samsung Galaxy S21 Plus functions as a refined, balanced flagship featuring a durable matte Gorilla Glass Victus back and a unique Contour Cut camera design. It boasts a 6.7-inch Dynamic AMOLED 2X display with adaptive 120Hz, powerful Exynos 2100 or Snapdragon 888 performance, and a robust 4,800 mAh battery that easily lasts over a day. While praised for its design and screen, the device is criticized for downgrading to a 1080p display, removing microSD storage, and offering limited camera zoom compared to the S21 Ultra.
The Samsung Galaxy S21 5G is characterized as a "rational" flagship that balances a compact, ergonomic design with a durable polycarbonate back. Its 6.2-inch Dynamic AMOLED 2X display offers a 120Hz adaptive refresh rate, ensuring a smooth, vibrant experience despite the resolution drop. Performance is driven by the Exynos 2100/Snapdragon 888 chipsets, resulting in top-tier speed, while camera capabilities are enhanced through better software, including Director's View and improved Night Mode. Key concessions to reach a lower price point include the lack of a microSD card slot, the omission of a charger/headphones in the box, and the absence of a 3.5mm jack. While the 4,000mAh battery typically lasts through moderate usage, it may struggle under heavy 5G or high-brightness conditions. Ultimately, the S21 is positioned as a solid, value-driven choice for users seeking flagship performance without the premium price of the Ultra model.
The Techzine.nl review characterizes the Samsung Galaxy S21 as a "refined" flagship that prioritizes usability over top-tier specs, featuring a 6.2-inch Dynamic AMOLED 2X display with a 120Hz refresh rate. While offering strong performance via the Exynos 2100 chipset, the device compromises with a plastic back and lower screen resolution compared to its predecessor. Pros include an improved, faster fingerprint sensor and a capable triple-camera system, though cons include the removal of the charger, headphones, and microSD slot. With a 4,000mAh battery providing average endurance, the S21 is positioned as an ergonomic and more accessible, budget-friendly entry into Samsung's 2021 flagship lineup. The review concludes that it is a solid choice for users seeking a compact, high-performance phone, provided they accept the move to a polycarbonate body.
The Samsung Galaxy S21+ 5G is positioned by Tweakers as a strong, all-round flagship that strikes a balance in the S21 lineup, featuring a premium glass-and-metal design. It boasts high-end performance via the Exynos 2100/Snapdragon 888, a fluid 120Hz AMOLED display, and reliable, all-day battery life. Key compromises to achieve its price point include a lower 1080p screen resolution compared to its predecessor, the removal of microSD storage, and the exclusion of a charger in the box.
The Samsung Galaxy S21+ 5G (256 GB) is recognized as a high-quality, large-screen smartphone featuring a 6.7-inch AMOLED 120Hz display, robust build quality with Gorilla Glass Victus, and IP68 water resistance. Performance is driven by top-tier processors (Snapdragon 888/Exynos 2100) and a versatile triple-camera system, though it lacks a microSD slot for storage expansion. While offering excellent battery life, the device ships without a charger or headphones in the box, representing a shift towards minimalism in packaging. For more details, visit Consumentenbond.
The Samsung Galaxy S21 Plus is positioned as a balanced, large-screen flagship featuring a 6.7-inch 120Hz AMOLED display, a premium matte glass design, and high-end performance via the Snapdragon 888 or Exynos 2100 chipset. Key strengths include solid 4,800mAh battery life and a reliable in-display fingerprint sensor, offering a premium experience similar to the Ultra model. However, the device presents several trade-offs, including a reduced 1080p screen resolution, lack of a microSD card slot, no charger in the box, and camera hardware that largely mirrors the previous generation without the advanced zoom capabilities of the S21 Ultra. These omissions make the device a contentious choice for users prioritizing maximum specifications. Targeted at users upgrading from older devices like the Galaxy S10, the S21 Plus offers a refined One UI 3.1 experience, but it is considered a lateral move for S20 series owners. It serves as a middle-ground option for those wanting a large screen without paying for the premium S21 Ultra.
