Ratings

The Samsung Galaxy S21 Ultra 5G, released in early 2021, and the Google Pixel Fold, launched in mid-2023, represent distinct approaches to high-end smartphone design. While the S21 Ultra offers a traditional premium smartphone experience with a large, flat display, the Pixel Fold introduces a foldable design, transforming from a compact device into a larger tablet-like screen. These differences cater to varying user preferences, particularly in screen utility and form factor.

Scores

Durability

When considering the long-term usability of these devices, their release timelines and software support policies are key factors. The Galaxy S21 Ultra 5G, being an earlier release, has a shorter remaining software support window compared to the newer Pixel Fold.

  • Software Longevity: The Samsung Galaxy S21 Ultra 5G, released in January 2021, received its final major Android OS update with Android 15 (One UI 7) in the first half of 2025, with security updates continuing quarterly until January 2026. The Google Pixel Fold, launched in June 2023, is guaranteed five years of OS and security updates from its release, extending its support until at least June 2028 for security updates and June 2026 for OS updates.
  • Repairability: The Galaxy S21 Ultra 5G received a repairability score of 3 out of 10 from iFixit, largely due to the extensive use of glue for its battery, display, and rear panel, making repairs challenging. The Pixel Fold received a PBK Reviews repairability score of 6.5 out of 10, with iFixit noting that Google provides spare parts and guides, making many repairs possible, though the USB-C port is soldered, and battery pull tabs can be delicate.
  • Practical Lifespan: Users prioritizing extended software updates and potentially easier access to repair resources may find the Pixel Fold to offer a longer practical lifespan. However, the inherent complexity and delicate nature of foldable screens mean that the Pixel Fold's physical durability over many years of folding and unfolding is a consideration.

The Samsung Galaxy S21 Ultra 5G and the Google Pixel Fold cater to different user priorities, reflecting their distinct designs and release timelines. Users often praise the S21 Ultra for its robust camera system, particularly its versatile zoom capabilities, and its vibrant, high-resolution display. Some common criticisms for the S21 Ultra include its large size and weight, and for some users, battery life that might not consistently last a full day with heavy use.

The Google Pixel Fold is frequently lauded for its innovative foldable design, offering the utility of a larger screen in a more portable form factor. Its wider outer display is often preferred for one-handed use compared to other foldables, and its camera system benefits from Google's renowned image processing. However, user concerns for the Pixel Fold often revolve around its overall weight, average battery life for a device of its class, and the inherent durability considerations of a foldable screen.

Users prioritizing a traditional, high-performance smartphone with an exceptional camera zoom and a single, expansive display may find the Galaxy S21 Ultra 5G well-suited to their needs. Conversely, those who value the versatility of a foldable screen for enhanced multitasking and media consumption, coupled with Google's signature camera experience, may lean toward the Pixel Fold. Both devices represent premium Android experiences, and choosing between them often comes down to whether a conventional flagship or an innovative foldable form factor aligns better with individual usage patterns. For those considering either device, exploring quality-assured refurbished options can be a sustainable choice.
