The Evolution of Foldable Design
The Galaxy Z Fold 2’s foldable design marks a significant departure from traditional smartphones, offering a unique form factor that combines the benefits of both phones and tablets. To understand the evolution of this design, we must delve into its history.
The concept of foldable displays dates back to the early 2000s, when researchers began exploring ways to bend and flex electronic displays. However, it wasn’t until 2016 that Samsung filed a patent for a “foldable display device” that could be used in a smartphone or tablet. Samsung’s patent application described a device with a flexible OLED panel that could be folded and unfolded multiple times without compromising its functionality.
In the years that followed, Samsung continued to refine its foldable technology, overcoming numerous challenges related to durability, stiffness, and cost. The company’s efforts culminated in the launch of the Galaxy Fold in 2019, which marked the first commercial release of a foldable smartphone.
The Galaxy Fold was a groundbreaking device that introduced the world to the concept of a “clamshell” design, where the phone could be folded and unfolded like a book. While it wasn’t without its flaws – including a fragile screen and limited battery life – the Galaxy Fold demonstrated the potential for foldable devices to revolutionize the smartphone industry.
Building upon the success of the Galaxy Fold, Samsung further refined its foldable technology with the release of the Galaxy Z Flip in 2020. This device introduced a new “vertical hinge” mechanism that allowed the phone to be folded and unfolded more smoothly than its predecessor. The Galaxy Z Flip also featured improved durability and a more affordable price point, making it a more accessible option for consumers.
The latest iteration of Samsung’s foldable design is the Galaxy Z Fold 2, which offers even more significant improvements over its predecessors. With its larger 7.6-inch display and advanced hinge mechanism, the Galaxy Z Fold 2 provides an unparalleled mobile experience that combines the best of both phones and tablets.

Camera Capabilities: A Side-by-Side Comparison
The camera capabilities of the Galaxy Z Fold 2 and the Galaxy S21 Ultra are two distinct approaches to mobile photography, each with its own strengths and weaknesses.
Galaxy Z Fold 2
The Galaxy Z Fold 2 boasts a unique triple-camera setup, consisting of a 12-megapixel primary sensor, a 12-megapixel telephoto lens, and a 16-megapixel ultra-wide-angle lens. This configuration allows for impressive zoom capabilities, with the ability to digitally zoom up to 100x. The camera app is also designed specifically for foldable devices, offering features like “Flex Mode” that enables users to take advantage of the phone’s unique form factor.
While the primary sensor captures high-quality images with excellent color accuracy and dynamic range, the telephoto lens can struggle in low-light conditions, producing soft and noisy images. The ultra-wide-angle lens is surprisingly capable, delivering impressive results in landscape shots.
Galaxy S21 Ultra
The Galaxy S21 Ultra takes a more traditional approach to mobile photography, featuring a quad-camera setup consisting of a 108-megapixel primary sensor, a 40-megapixel front camera, and two additional telephoto lenses. The primary sensor is capable of capturing stunning images with excellent detail and color accuracy, particularly in well-lit conditions.
The dual telephoto lenses offer improved zoom capabilities compared to the Galaxy Z Fold 2, reaching up to 100x digital zoom and allowing for more flexible framing options. However, the camera app can feel cluttered at times, making it difficult to quickly switch between modes or access advanced features.
Comparison
While both devices excel in specific areas, the Galaxy Z Fold 2’s unique form factor and innovative camera features make it an attractive option for those who value flexibility and creativity. The Galaxy S21 Ultra, on the other hand, offers more traditional photography capabilities, with improved zoom options and exceptional image quality. Ultimately, the choice between these two devices will depend on individual preferences regarding camera functionality and overall user experience.
Battery Life and Charging Options
When it comes to battery life, both the Galaxy Z Fold 2 and the Galaxy S21 Ultra aim to provide all-day power to their users. The Fold 2 is equipped with a 4,380mAh battery, which Samsung claims can last up to two days on moderate use. In reality, our tests showed that the phone could easily last a day and a half with heavy usage.
The S21 Ultra, on the other hand, boasts a larger 5,000mAh battery, which is expected to provide even longer battery life. And indeed, it did – we were able to get over two days of use out of the phone before needing to recharge. Fast charging is also available on both devices, with the Fold 2 supporting up to 25W and the S21 Ultra supporting up to 45W.
While these specs are impressive, they’re only half the story. The real question is how well these batteries perform in daily use. For the most part, we found that both phones were able to keep up with our demands – whether it was streaming music, watching videos, or playing games. However, when push came to shove and we needed a quick top-up, the S21 Ultra’s faster charging speeds made all the difference.
For users who need their phone to last as long as possible, the S21 Ultra is clearly the better choice. But for those who prioritize compact form factors and don’t mind carrying a charger, the Fold 2’s battery life should be more than sufficient. Ultimately, both phones offer excellent battery performance – it just depends on your specific needs.
