Ratings

The Samsung Galaxy S23, released in February 2023, and the Samsung Galaxy S24 Ultra, launched in January 2024, are both high-end Android smartphones from Samsung's flagship Galaxy S series. While they share a common operating system and premium features, the S24 Ultra introduces advancements in durability, processing power, and long-term software support, alongside refinements in its display and camera system. These differences cater to varying user priorities, from compact design preferences to extended device longevity.

Scores

Durability

The longevity of a smartphone is influenced by its physical resilience and the duration of software support it receives. These two models present distinct offerings in both aspects.

  • Software Support: The Galaxy S23 was launched with a commitment of four major Android operating system updates and five years of security updates, extending its support until approximately 2028. In contrast, the Galaxy S24 Ultra sets a new standard with an impressive seven years of both operating system and security updates, ensuring a longer period of current software features and security patches.
  • Physical Durability: The Galaxy S23 features Gorilla Glass Victus 2 on its front and back, along with an Armor Aluminum frame, providing robust protection against everyday wear and tear. The Galaxy S24 Ultra elevates this with Corning Gorilla Glass Armor on its display, which offers enhanced scratch resistance, and a titanium frame, contributing to its overall structural integrity and resistance to bending.
  • Practical Lifespan: Users can expect both devices to perform reliably for several years. However, the S24 Ultra's extended software support means it will remain current with the latest Android features and security updates for a significantly longer period, potentially making it a more future-proof option for those who keep their devices for many years.

Performance

Performance is a key differentiator, with the newer model benefiting from generational advancements in processing technology and efficiency.

  • Processing Capabilities: The Galaxy S23 handles demanding applications and multitasking smoothly, providing a responsive user experience for daily tasks and gaming. The Galaxy S24 Ultra, equipped with a newer generation processor, offers incremental improvements in speed and efficiency, resulting in even smoother operation for intensive tasks, faster app loading, and enhanced performance in graphically demanding games.
  • Battery Behavior: Both devices feature substantial battery capacities, with the Galaxy S23 housing a 3900 mAh battery and the Galaxy S24 Ultra a 5000 mAh battery. While the S23 offers good battery life for its size, the S24 Ultra generally provides longer endurance, often lasting through a full day of heavy use due to its larger battery and more power-efficient components.
  • Storage and Multitasking: Both models offer various internal storage options, typically starting from 128GB or 256GB. The Galaxy S23 usually comes with 8GB of RAM, while the S24 Ultra features 12GB of RAM. This additional RAM in the S24 Ultra can contribute to slightly more seamless multitasking and app retention in memory, particularly for users who frequently switch between many applications.

Screen quality

Both devices offer high-quality displays, but the S24 Ultra introduces several enhancements that refine the viewing experience.

  • Display Technology and Clarity: Both the Galaxy S23 and S24 Ultra feature Dynamic AMOLED 2X displays, providing vibrant colors and deep blacks. The S23 has a 6.1-inch display with a resolution of 2340x1080 pixels, while the S24 Ultra boasts a larger 6.8-inch display with a resolution of 3120x1440 pixels, offering slightly greater pixel density and sharpness.
  • Brightness and Refresh Rate: Both phones support a 120Hz adaptive refresh rate for smooth scrolling and responsiveness. The S24 Ultra significantly increases peak brightness to 2600 nits, compared to the S23's 1750 nits, making the S24 Ultra's display more visible in bright outdoor conditions.
  • Design and Viewing Experience: The Galaxy S23 features a curved display, which some users find aesthetically pleasing and comfortable to hold. The S24 Ultra, however, adopts a flat display, which can be beneficial for S Pen usage and may reduce accidental touches along the edges. The S24 Ultra also incorporates an anti-reflective coating, further enhancing outdoor visibility and reducing glare.

The camera systems on both devices are highly capable, delivering excellent results in various conditions, though the S24 Ultra brings a revised telephoto setup.

  • Main and Ultrawide Cameras: Both the Galaxy S23 and S24 Ultra feature a 200MP main camera and a 12MP ultrawide camera, capable of capturing detailed and vibrant images. User experiences suggest minimal differences in daylight photos from the main sensor, with both producing high-quality results.
  • Telephoto Capabilities: The S23 includes a 10MP 10x optical telephoto lens, alongside a 10MP 3x telephoto. The S24 Ultra replaces the 10x optical lens with a 50MP 5x optical telephoto lens, which is designed to achieve lossless 10x zoom through advanced processing. This change means the S24 Ultra offers higher resolution at 5x zoom, while the S23 Ultra retains a dedicated 10x optical zoom.
  • Low-Light and Video Performance: Both phones excel in low-light photography with dedicated night modes. Video recording quality is strong on both, supporting resolutions up to 8K. The S24 Ultra's larger telephoto sensor can improve low-light performance at its native zoom levels.

Miscellaneous

Beyond core specifications, several practical elements contribute to the overall user experience of these devices.

  • Connectivity and Ports: Both the Galaxy S23 and S24 Ultra offer comprehensive connectivity, including 5G support, the latest Wi-Fi standards, and Bluetooth. The S23 features a USB-C port for charging and data transfer, a standard also found on the S24 Ultra.
  • Biometric Security and Features: Both devices incorporate advanced biometric security, typically including an under-display fingerprint sensor and facial recognition. The S24 Ultra, being an Ultra model, includes an integrated S Pen stylus, offering enhanced productivity for note-taking, drawing, and navigation, a feature not present on the standard S23.
  • Physical Design and Handling: The Galaxy S23 is a more compact device, weighing 168 grams and measuring 146.3 x 70.9 x 7.6mm, making it easier for one-handed use. The S24 Ultra is a larger and heavier device at 232 grams and 162.3 x 79 x 8.6mm, reflecting its larger screen and additional features. The S24 Ultra's flat display and titanium frame contribute to a different in-hand feel compared to the S23's curved screen and aluminum frame.

User sentiment for both the Galaxy S23 and S24 Ultra highlights their strengths and areas of consideration. The Galaxy S23 is often praised for its balanced performance, comfortable size, and capable camera system, with many users appreciating its overall reliability and the vividness of its display. Some users, however, note its relatively shorter software support window compared to newer models.

The Galaxy S24 Ultra receives commendation for its cutting-edge processor, significantly extended software update policy, and the enhanced durability provided by its titanium frame and Gorilla Glass Armor. Its brighter, flat display with anti-reflective coating is also a frequent highlight. Criticisms sometimes point to the revised telephoto camera setup, with some users preferring the S23 Ultra's dedicated 10x optical zoom, and occasional reports of display color saturation differences or graininess in early batches, though these have largely been addressed by software updates.

Users prioritizing a more compact form factor, a curved display, and a slightly more established camera zoom system may find the Galaxy S23 well-suited to their needs. Conversely, individuals seeking the longest possible software support, a larger flat display with superior brightness and anti-glare properties, and the latest processing power for demanding tasks will likely lean towards the Galaxy S24 Ultra. Both devices offer a premium Android experience, and choosing between them often comes down to these specific preferences. For those considering either model, exploring quality-assured refurbished options can provide an eco-friendly alternative.
