Galaxy A51 vs Google Pixel 7

The Samsung Galaxy A51 (released in December 2019) and the Google Pixel 7 (released in October 2022) are Android smartphones from different generations, targeting distinct user experiences. While the Galaxy A51 was positioned as a feature-rich mid-range device, the Pixel 7 offers a more advanced processing platform and enhanced camera capabilities. Both devices run on the Android operating system, but their software support timelines and feature sets reflect their respective release years.

The practical lifespan of a smartphone is influenced by its release timeline, software support, and physical durability. These two devices show notable differences in these areas.

• Release Timeline: The Galaxy A51, launched in late 2019, is an older device compared to the Pixel 7, which arrived in late 2022. This age difference directly impacts their remaining software support and hardware longevity.
• OS Support Duration: The Galaxy A51 initially received three generations of Android software updates and four years of security updates from its release. The Pixel 7, on the other hand, was promised five years of OS and security updates from its launch date, extending its support significantly further into the future.
• Repairability: The Galaxy A51 has a repairability score of approximately 6.5 out of 10, with some components like the battery and screen being individually replaceable, though requiring some technical knowledge due to adhesive and small parts. The Pixel 7 also has a repairability score around 6 to 6.5 out of 10, with screen replacements being relatively straightforward, but battery removal can be complex due to strong adhesive and the charging port being soldered to the motherboard.

Performance is a key differentiator, impacting how smoothly applications run and how efficiently daily tasks are handled. The gap in release dates between these two models is evident in their processing power and overall responsiveness.

• Overall System Responsiveness: The Pixel 7, with its more recent processor, offers a significantly more fluid and responsive user experience, handling demanding applications and multitasking with greater ease. Users report smoother animations and quicker app launches. The Galaxy A51 provides adequate performance for everyday tasks and lighter use, but may show slowdowns with more intensive applications or extensive multitasking.
• Battery Behavior: The Pixel 7 features a 4355 mAh battery, which users generally find robust enough for a full day of moderate to heavy use, though intensive camera use can drain it faster. The Galaxy A51 comes with a 4000 mAh battery, offering a full day of use for many, but heavy users might find themselves needing to recharge more frequently.
• Storage and RAM: The Pixel 7 typically comes with 8 GB of RAM and storage options of 128 GB or 256 GB, providing ample space and memory for smooth operation. The Galaxy A51 offered various configurations, including 4 GB, 6 GB, or 8 GB of RAM, and 64 GB, 128 GB, or 256 GB of storage, with expandable storage via microSD card.

The display is the primary interface for user interaction, and both devices offer distinct viewing experiences based on their panel technology and features.

• Display Technology and Clarity: The Galaxy A51 features a 6.5-inch Super AMOLED Infinity-O display with a 1080 x 2400 pixel resolution, providing vibrant colors and deep blacks. The Pixel 7 has a slightly smaller 6.3-inch OLED display with the same 1080 x 2400 pixel resolution, also known for its deep blacks and vibrant color reproduction.
• Brightness and Refresh Rate: The Pixel 7's OLED display offers higher peak brightness, making it more comfortable for outdoor viewing and supporting HDR content effectively. It also features a 90 Hz refresh rate, contributing to smoother scrolling and a more fluid visual experience. The Galaxy A51's Super AMOLED display operates at a standard 60 Hz refresh rate and has good brightness for typical indoor use, though it may be less bright in direct sunlight compared to the Pixel 7.
• Screen Protection: The Galaxy A51 uses Corning Gorilla Glass 3 for screen protection. The Pixel 7 features more advanced Corning Gorilla Glass Victus, offering enhanced durability against drops and scratches.

Camera performance is a significant factor for many users, and these two smartphones approach photography with different strengths and capabilities.

• Rear Camera System: The Galaxy A51 features a quad-camera setup with a 48 MP main sensor, a 12 MP ultrawide, a 5 MP macro, and a 5 MP depth sensor, offering versatility for various shots. The Pixel 7 has a dual-camera system, including a 50 MP wide-angle main camera and a 12 MP ultrawide camera. The Pixel 7's main camera, combined with its advanced computational photography, often produces brighter, clearer, and more natural-looking photos, especially in challenging conditions.
• Low-Light and Video Performance: The Pixel 7 excels in low-light photography with its Night Sight feature, capturing images quickly and with good detail. It also offers 4K video recording at 60 frames per second. The Galaxy A51 can capture decent low-light photos, but the Pixel 7 generally outperforms it in this area. The Galaxy A51 supports 4K video recording at 30 frames per second.
• Front Camera and Audio: The Galaxy A51 has a 32 MP front camera. The Pixel 7 features a 10.8 MP ultrawide front camera, which is noted for producing good selfies. Both devices offer stereo speakers for media consumption, and the Galaxy A51 includes a 3.5mm headphone jack, which is absent on the Pixel 7.
