Samsung Galaxy Z Fold3 5G

  • Innovative foldable display for multitasking
  • More powerful Snapdragon 888 processor
  • S Pen support (sold separately)
  • Under-display camera for immersive viewing

  • Significantly shorter battery life
  • Higher price point
  • Durability concerns with foldable screen

Samsung Galaxy Note20 Ultra 5G

  • Exceptional battery life
  • Brighter display for outdoor visibility
  • Integrated S Pen for productivity
  • More mature and refined software experience

  • Less powerful processor compared to Z Fold3
  • Regional chipset variations (Exynos vs Snapdragon)
  • Conventional smartphone form factor
  • No foldable display for tablet-like experience

Display Comparison

The Note20 Ultra boasts a brighter display, peaking at 1024 nits, compared to the Z Fold3’s 922 nits, making it more visible outdoors. However, the Z Fold3’s foldable 7.6-inch internal display fundamentally alters the experience, offering a tablet-like canvas. While the Note20 Ultra’s 6.9-inch display is excellent, it can’t match the Z Fold3’s versatility. The Z Fold3 utilizes a more advanced under-display camera (UDC) for a less intrusive viewing experience, though image quality from that camera is lower. Both displays offer a 120Hz refresh rate, but the Z Fold3’s is dynamically adjusted, potentially impacting smoothness in certain scenarios.

Camera Comparison

Both phones offer versatile camera systems, but the Z Fold3’s camera benefits from the newer chipset’s image signal processor (ISP). While detailed sensor specs are not provided, the Z Fold3’s processing likely results in improved dynamic range and low-light performance. The Note20 Ultra’s camera system is known for its excellent zoom capabilities and color science. Both phones are capable of recording high-quality video, but the Z Fold3’s newer processor may offer more advanced video features. The inclusion of a 2MP macro camera on the Note20 Ultra is largely inconsequential, offering limited practical benefit.

Performance

The Z Fold3’s Snapdragon 888 5G (5nm) chipset represents a generational leap over the Note20 Ultra’s Exynos 990 (7nm+) or Snapdragon 865 5G+ (7nm+), depending on the region. The 5nm process node of the Snapdragon 888 delivers improved power efficiency and thermal performance, translating to sustained performance during demanding tasks. The Z Fold3’s CPU, with its Cortex-X1 prime core, offers a noticeable performance advantage in single-core tasks. While the Note20 Ultra remains capable, the Z Fold3’s chipset provides a smoother experience for gaming and resource-intensive applications. The Note20 Ultra's regional chipset variation (Exynos vs Snapdragon) introduces performance inconsistencies, a factor the Z Fold3 avoids.

Battery Life

The Note20 Ultra’s 88-hour endurance rating significantly surpasses the Z Fold3’s 75-hour rating. This difference is primarily due to the Z Fold3’s larger, more power-hungry foldable display and the demands of powering two screens. While both phones support 25W wired charging, the Note20 Ultra’s larger battery means it will take longer to fully charge. The Z Fold3 offers 11W wireless charging, while the Note20 Ultra supports 15W wireless charging (Qi), providing a slightly faster wireless charging experience. The 4.5W reverse wireless charging is identical on both devices.

Buying Guide

Buy the Samsung Galaxy Z Fold3 5G if you need a tablet-sized screen in your pocket for multitasking, content creation, and immersive media consumption, and are willing to accept shorter battery life and a higher price. Buy the Samsung Galaxy Note20 Ultra 5G if you prefer a more conventional, refined smartphone experience with exceptional battery life, a superb camera, and the integrated S Pen for productivity and creativity.

Frequently Asked Questions

❓ Does the Exynos 990 in the global Note20 Ultra overheat during prolonged gaming sessions?
The Exynos 990 has been known to exhibit thermal throttling under sustained load, particularly in warmer environments. While not a deal-breaker, users may experience reduced performance during extended gaming sessions. The Snapdragon 865+ variant in the US model mitigates this issue.
❓ Is the under-display camera on the Z Fold3 noticeable during everyday use?
The under-display camera is visible as a slight distortion in the display when viewing content with a dark background. While Samsung has made improvements in minimizing this effect, it's still noticeable. It's a trade-off for achieving a truly immersive, uninterrupted viewing experience.
❓ How does the Z Fold3 handle multitasking compared to the Note20 Ultra?
The Z Fold3 excels at multitasking thanks to its larger, foldable display and enhanced software features like App Pair. You can run three apps simultaneously and easily switch between them, offering a productivity boost over the Note20 Ultra's more traditional multitasking capabilities.
❓ Is the Z Fold3's screen durable enough for daily use?
While Samsung has made significant improvements to the durability of the Z Fold3's foldable display, it's still more susceptible to damage than traditional smartphone screens. Using a screen protector and handling the device with care is recommended.
