Samsung Galaxy Note20

  • Integrated S Pen for productivity and creativity
  • More affordable price point (especially now)
  • Expandable storage via microSD card (market dependent)

  • Older chipset with lower performance
  • Less efficient power consumption
  • Potentially lower peak display brightness

Samsung Galaxy S21+ 5G

  • Faster and more efficient chipset (Exynos 2100/Snapdragon 888)
  • Brighter and more vibrant display
  • Improved camera processing and image quality

  • Lacks S Pen functionality
  • Generally more expensive
  • No expandable storage

Display Comparison

The S21+ 5G boasts a brighter display, reaching a measured 883 nits, compared to the Note20’s unspecified peak brightness. While both utilize Dynamic AMOLED 2X technology, the S21+’s higher peak brightness translates to better visibility in direct sunlight. Both feature a 120Hz refresh rate, but the S21+’s adaptive refresh rate, likely utilizing LTPO technology (though not explicitly stated), dynamically adjusts the refresh rate to conserve battery life. The S21+ also has an 'infinite' contrast ratio, indicating deeper blacks and more vibrant colors.

Camera Comparison

Both phones offer versatile camera systems, but the S21+ 5G benefits from the newer image processing capabilities of its chipset. While both are listed as having 'Photo / Video' capabilities, the S21+’s processing pipeline likely delivers improved dynamic range and noise reduction. The Note20’s camera system, while capable, is held back by the older chipset’s processing limitations. Details regarding sensor sizes and apertures are missing, but the S21+’s newer hardware suggests a slight edge in image quality, particularly in low-light conditions. The 2MP macro cameras on both devices are largely a marketing feature and offer limited practical benefit.

Performance

The core difference lies in the chipsets. The Note20 utilizes either the Exynos 990 (globally) or the Snapdragon 865+ (USA), both built on a 7nm+ process. The S21+ 5G, however, features the more advanced Exynos 2100 (international) or Snapdragon 888 (USA/China), fabricated on a 5nm process. This smaller node allows for increased transistor density, resulting in improved performance and efficiency. The S21+'s CPU, with its Cortex-X1 prime core clocked at 2.9 GHz (international) or 2.84 GHz (USA/China), outperforms the Note20’s Mongoose M5 core. The S21+ also benefits from faster RAM, likely LPDDR5, contributing to smoother multitasking.

Battery Life

Both the Note20 and S21+ 5G achieve an endurance rating of 114 hours, suggesting similar real-world battery life despite potential differences in battery capacity (not specified in the provided data). Both support 25W wired charging with PD3.0, 15W wireless charging (Qi), and 4.5W reverse wireless charging. The S21+’s more efficient chipset, however, may translate to slightly longer screen-on time, especially during demanding tasks. The adaptive refresh rate on the S21+ also contributes to battery conservation.

Buying Guide

Buy the Samsung Galaxy Note20 if you absolutely require the S Pen for note-taking, sketching, or remote control functionality and prioritize a lower upfront cost. Buy the Samsung Galaxy S21+ 5G if you value raw performance, a brighter and more modern display, and a more streamlined software experience, even if it means sacrificing the S Pen.

Frequently Asked Questions

❓ Does the Exynos 990 in the Note20 suffer from thermal throttling during extended gaming sessions?
The Exynos 990 is known to be less thermally efficient than the Snapdragon 865+ or 888. While the Note20 can handle gaming, prolonged sessions with demanding titles may result in noticeable throttling, leading to reduced frame rates and performance. The S21+ 5G, with its 5nm chipset, manages heat more effectively.
❓ Is the S Pen a significant advantage for everyday use, or is it a niche feature?
The S Pen's utility depends heavily on individual usage. For students, artists, or professionals who frequently take notes, sketch, or require precise input, the S Pen is a game-changer. However, for users who primarily consume content and communicate via text or voice, the S Pen may remain largely unused.
❓ How does the camera performance differ in video recording between the Note20 and S21+ 5G?
The S21+ 5G likely offers superior video recording capabilities due to its more advanced image signal processor (ISP). Expect better stabilization, dynamic range, and detail in videos captured on the S21+ 5G, especially in challenging lighting conditions. The Note20 is still capable, but the S21+ provides a more polished and professional result.
