Ratings

The Samsung Galaxy S23 Ultra, released in February 2023, and the Samsung Galaxy Z Fold4, launched in August 2022, represent distinct approaches to high-end smartphone design. While both devices operate on the Android platform with Samsung's One UI, their fundamental form factors — a traditional slab versus a foldable — create significant differences in user experience. The S23 Ultra focuses on delivering a premium, conventional smartphone experience with advanced camera capabilities and an integrated stylus, whereas the Z Fold4 offers a versatile, tablet-like display that folds for portability, catering to users seeking enhanced multitasking and a larger screen.

Scores

Durability

When considering the long-term usability of these devices, their release timelines and software support are key factors.

  • Software Longevity: The Galaxy S23 Ultra, being released later in February 2023, is expected to receive software updates for a slightly longer period than the Galaxy Z Fold4, which launched in August 2022. Samsung typically provides four generations of Android OS upgrades and five years of security updates for its flagship devices, meaning the S23 Ultra will benefit from an additional year of official support.
  • Physical Durability: The Galaxy S23 Ultra features a robust design with Gorilla Glass Victus 2 on both the front and back, along with an aluminum frame, offering strong resistance to drops and scratches. It also boasts an IP68 rating for dust and water resistance, protecting against submersion. The Galaxy Z Fold4, while featuring Gorilla Glass Victus+ on its cover screen and back, has a more complex foldable design. Its main inner display uses Samsung's Ultra-Thin Glass with protective layers, and it carries an IPX8 water resistance rating, but lacks official dust resistance due to its folding mechanism.
  • Repairability Considerations: The traditional design of the S23 Ultra generally makes it more straightforward to repair compared to the intricate folding mechanism and dual-screen setup of the Z Fold4. The Z Fold4's foldable display, while improved for durability, remains a more delicate component.

Miscellaneous

Beyond core specifications, several practical elements contribute to the overall user experience of each device.

  • Connectivity and Ports: Both smartphones support modern connectivity standards, including 5G, Wi-Fi 6E, and Bluetooth 5.3 (S23 Ultra) or 5.2 (Z Fold4). They both utilize a USB-C port for charging and data transfer, and neither includes a traditional 3.5mm headphone jack.
  • Biometrics and Sensors: The Galaxy S23 Ultra features an ultrasonic in-screen fingerprint sensor for secure unlocking. The Galaxy Z Fold4 incorporates a side-mounted fingerprint sensor, often integrated into the power button. Both devices include a standard array of sensors such as accelerometers, gyroscopes, and barometers.
  • Design and Handling: The S23 Ultra has a traditional smartphone form factor, weighing 233g and measuring 8.9mm thick, offering a familiar feel. The Z Fold4, at 263g, is heavier and significantly thicker when folded (14.2-15.8mm), but unfolds into a much thinner device (6.3mm), providing a larger screen in a compact, albeit heavier, package. The S23 Ultra also features an integrated S Pen stylus, while the Z Fold4 supports an S Pen (sold separately) but does not have a built-in storage slot.

The Samsung Galaxy S23 Ultra and Galaxy Z Fold4 cater to different user preferences, each excelling in its own domain. Users often praise the S23 Ultra for its exceptional camera system, particularly its zoom capabilities and high-resolution main sensor, which consistently delivers detailed and vibrant photos. Its long-lasting battery life is also a frequent highlight, allowing many users to comfortably get through a full day of heavy use. Some common feedback includes its large size, which can be challenging for one-handed operation, though this is also seen as a benefit for media consumption and productivity.

The Galaxy Z Fold4 is frequently lauded for its innovative foldable design, offering the utility of a large tablet screen in a pocketable form factor. Its multitasking capabilities, allowing multiple apps to run simultaneously on the expansive inner display, are a significant draw for productivity-focused users. The unique form factor and the immersive experience of the large screen are often cited as its main strengths. However, some users note the visible crease on the main display and its increased thickness and weight when folded compared to traditional smartphones. The battery life, while generally sufficient, may require more frequent charging for those who heavily utilize the larger inner screen.

Users prioritizing a top-tier, conventional smartphone experience with industry-leading camera performance, robust battery life, and an integrated stylus will find the Galaxy S23 Ultra well-suited to their needs. Its consistent performance and durable build make it a reliable choice for everyday use and demanding tasks. Conversely, users who value innovation, a large, immersive display for media and multitasking, and a device that transforms from a phone to a tablet will lean towards the Galaxy Z Fold4. Both devices offer a premium Android experience, and for those looking for an eco-friendly alternative, quality-assured refurbished options are available, providing access to these advanced technologies sustainably.
