Verdict

The Samsung Galaxy S21 Ultra (12GB + 128GB) is a top-tier Android flagship with a massive 6.8-inch Dynamic AMOLED 2X display featuring an adaptive 120Hz refresh rate and QHD+ resolution, powered by either the speedy Snapdragon 888 or Exynos 2100 processor with 12GB of RAM for seamless multitasking and 5G connectivity. Its primary strength is a versatile quad-camera system, including a 108MP main sensor and two 10MP telephoto lenses providing 3x and 10x optical zoom (up to 100x Space Zoom), plus a substantial 5,000mAh battery that easily lasts a full day of heavy usage. Key pros include the stunning screen, exceptional zoom capabilities, powerful performance, and S Pen support (sold separately), while cons involve its significant weight and bulk, the lack of a microSD card slot for storage expansion, the absence of a charger or headphones in the box, and a high initial price point.

Samsung Galaxy S21 Ultra 5G: First Impression

The Samsung Galaxy S21 Ultra 5G (128GB) is a large, premium device featuring a standout "contour-cut" camera housing, a 6.8-inch Dynamic AMOLED 2X display, and S Pen support. Pros include an exceptional 120Hz display with high brightness, a powerful Exynos 2100 processor, and a versatile camera system with 10x optical zoom. Key cons involve its heavy, 227-gram weight, lack of a microSD card slot, and the absence of a charger or headphones in the box. Consumentenbond

Samsung Galaxy S21 Ultra review: finally everything in one place

The Samsung Galaxy S21 Ultra serves as a redemption for the S20, featuring a matte Phantom Black finish, a 6.8-inch Dynamic AMOLED 2X display, and improved camera integration, though its 227g-229g weight makes it difficult to hold. Key benefits include the introduction of S Pen support and a refined design, while drawbacks include the exclusion of the stylus from the box and its large form factor. The camera system boasts a 108MP main sensor with a 3x and 10x dual-telephoto setup, offering impressive, stable 100x zoom and advanced video features like 8K recording and Director's View. However, the device can overprocess images, and the high-zoom capabilities produce noisy images in low light. Powered by the Exynos 2100 or Snapdragon 888 and a 5,000 mAh battery, the device offers top-tier performance, though intensive use quickly drains the battery. Significant omissions include the removal of the microSD card slot and the charger from the box, alongside the end of software support as of February 2026.

Samsung Galaxy S21 and S21 Ultra – Samsung at the top

According to the review from FWD.nl, the Samsung Galaxy S21 and S21 Ultra represent a refined peak for the brand, balancing high-end performance with a more competitive pricing strategy. The review highlights a "striking new design" that integrates the camera module into the frame, with the S21 Ultra offering a premium glass build, while the standard S21 utilizes a high-quality plastic back. Pros include exceptionally fast performance, vibrant 120Hz screens, and the Ultra’s added S Pen support, though significant cons include the removal of the microSD card slot and the absence of a charger. The camera systems, particularly the Ultra's 108MP sensor and 10x optical zoom, are highlighted for their sharpness, and the "Zoom Lock" feature is praised for stabilizing long-distance shots. However, battery life is identified as a potential issue, as power-heavy features like the high-resolution display and 5G can drain the battery quickly.

Samsung Galaxy S21 & S21 Ultra Review - Putting on the brakes for distinction and a better price

Tweakers.net reviews the Samsung Galaxy S21 series, highlighting a strategic shift toward lower pricing that includes notable hardware trade-offs on the base model. The S21 Ultra is positioned as the true, premium flagship with a top-tier WQHD+ 120Hz display, while the standard S21 features a polycarbonate back and 1080p resolution, which feels like a downgrade from its predecessor to achieve a better price point. Camera capabilities are a highlight, particularly the Ultra’s 108MP sensor, improved zoom stability, and new S Pen support, though the removal of the microSD slot and charger across the lineup is noted as a drawback. Performance with the Exynos 2100 is excellent and the Ultra offers solid battery life, leading to a conclusion that the S21 Ultra is for power users, while the S21 serves as a budget-friendly option.
