Samsung Galaxy Note20 Ultra 5G
- Integrated S Pen for productivity and creativity
- Premium build quality and design
- Capable camera system for most users
- Less efficient chipset leads to shorter battery life
- Older processor struggles with demanding tasks
- S Pen functionality may be unnecessary for some
Samsung Galaxy S21 Ultra 5G
- Significantly improved battery life
- More powerful and efficient processor
- Superior camera performance, especially in low light
- More versatile zoom capabilities
- Lacks integrated S Pen
- Can be more expensive than the Note20 Ultra
Display Comparison
Both the Note20 Ultra and S21 Ultra boast 'Infinite' contrast ratio displays, indicating excellent black levels. However, the S21 Ultra’s display, while measuring a similar 1023 nits peak brightness to the Note20 Ultra’s 1024 nits, benefits from a more advanced panel architecture. While neither device specifies LTPO, the S21 Ultra’s adaptive refresh rate is more refined, contributing to better power efficiency. Bezels are marginally slimmer on the S21 Ultra, offering a slightly more immersive viewing experience.
Camera Comparison
Both phones offer versatile camera systems, but the S21 Ultra takes a clear lead. While both are capable of excellent photo and video, the S21 Ultra’s larger main sensor (details missing in context, but generally understood to be larger) and improved image processing algorithms deliver superior low-light performance and dynamic range. The S21 Ultra’s laser autofocus system is also faster and more reliable than the Note20 Ultra’s. The inclusion of a dual-telephoto lens system on the S21 Ultra (details missing in context) provides greater zoom versatility, a feature absent on the Note20 Ultra. The 2MP macro cameras on both devices are largely inconsequential and offer minimal benefit.
Performance
The core difference lies in the chipset. The Note20 Ultra shipped with either the Exynos 990 (Global) or Snapdragon 865+ (USA), both built on a 7nm+ process. The S21 Ultra moved to a 5nm process with the Exynos 2100 (International) or Snapdragon 888 (USA/China). This process shrink, coupled with architectural improvements – the Cortex-X1 prime core in the S21 Ultra versus the Mongoose M5 in the Note20 Ultra – results in a noticeable performance uplift. The S21 Ultra’s CPU, with its Cortex-A78 cores, offers better sustained performance and thermal management compared to the Note20 Ultra’s Cortex-A76 cores. The S21 Ultra also benefits from faster LPDDR5 RAM, contributing to snappier multitasking.
Battery Life
The S21 Ultra’s endurance rating of 114 hours significantly surpasses the Note20 Ultra’s 88 hours. This improvement isn’t solely due to a larger battery (mAh not specified in context); the more efficient 5nm chipset plays a crucial role. Both phones support 25W wired charging, PD3.0, 15W wireless charging (Qi), and 4.5W reverse wireless charging. However, the S21 Ultra’s improved power efficiency translates to faster real-world charging times and longer periods between charges.
Buying Guide
Buy the Samsung Galaxy Note20 Ultra 5G if you prioritize the integrated S Pen experience and can find it at a substantial discount. It remains a capable device for productivity and creative tasks. Buy the Samsung Galaxy S21 Ultra 5G if you value longer battery life, a more powerful processor for demanding applications, and a more modern camera system with improved low-light performance. It's the better all-around flagship.
