Galaxy A51 vs Galaxy S22+ 5G

The Samsung Galaxy A51, released in late 2019, and the Samsung Galaxy S22 Plus 5G, launched in early 2022, represent different tiers and generations within Samsung's smartphone lineup. While both operate on the Android platform with Samsung's One UI, the S22 Plus 5G offers significant advancements in performance, camera capabilities, and overall build quality. This comparison will highlight the practical differences to help users determine which device best suits their needs.

The expected lifespan of a smartphone is heavily influenced by its release timeline and the duration of software support it receives.

• Release Timeline: The Galaxy A51 was released in December 2019, making it an older device compared to the Galaxy S22 Plus 5G, which launched in February 2022. This age difference directly impacts their remaining software support and hardware relevance.
• OS Support Duration: The Galaxy A51 launched with Android 10 and received its final major operating system update to Android 13. In contrast, the Galaxy S22 Plus 5G launched with Android 12 and is expected to receive four major OS updates, extending its software longevity significantly further, likely up to Android 16, along with five years of security updates.
• Practical Lifespan: Users prioritising long-term software support and access to the latest Android features will find the Galaxy S22 Plus 5G a more future-proof option. The A51 has already reached its end-of-life for major OS updates, meaning it will no longer receive new Android versions, though it may still get some security patches.
• Repairability: The Galaxy A51 generally has a moderate repairability score, estimated around 6 to 6.5 out of 10, with some modular components making certain repairs, like battery or screen replacement, feasible for those with technical knowledge. The Galaxy S22 Plus 5G, with its more premium and tightly integrated design, may present greater challenges for repairs, often requiring specialised tools and careful handling due to extensive use of adhesive.

The performance capabilities of these two devices cater to different user expectations, largely due to their respective hardware generations.

• Processor Capabilities: The Galaxy A51 is equipped with a mid-range processor, which capably handles everyday tasks such as web browsing, social media, and light applications. However, it may exhibit occasional slowdowns or longer loading times when running demanding applications or engaging in intensive multitasking. The Galaxy S22 Plus 5G features a flagship-tier processor, delivering robust performance for graphically intensive games, complex applications, and seamless multitasking without noticeable lag.
• System Responsiveness: The Galaxy S22 Plus 5G offers a consistently smooth and responsive user experience, with applications launching quickly and transitions feeling fluid. The A51 provides a satisfactory experience for general use, but the difference in speed and fluidity is apparent when directly compared.
• Battery Behaviour: The Galaxy A51 has a 4000 mAh battery, providing sufficient power for a full day of moderate use, though heavy users might find themselves needing to recharge sooner. The Galaxy S22 Plus 5G comes with a larger 4500 mAh battery and benefits from a more power-efficient processor and adaptive display technology. While its powerful components can consume more energy, its overall battery management is designed for extended usage, and it supports significantly faster 45W wired charging, 15W wireless charging, and 4.5W reverse wireless charging.
• Storage and RAM: The Galaxy A51 offers various RAM configurations (4GB, 6GB, 8GB) and storage options (64GB, 128GB, 256GB), with the added flexibility of microSD card expansion. The Galaxy S22 Plus 5G typically comes with 8GB of RAM and 128GB or 256GB of internal storage, but it does not support expandable storage.

Both devices feature AMOLED display technology, known for vibrant colours and deep blacks, but they differ in overall display experience and advanced features.

• Display Technology and Clarity: Both phones utilise Super AMOLED or Dynamic AMOLED 2X panels, providing excellent contrast and colour reproduction. The Galaxy A51 has a 6.5-inch Super AMOLED display with a 1080 x 2400 pixel resolution. The Galaxy S22 Plus 5G features a slightly larger 6.6-inch Dynamic AMOLED 2X display with a 1080 x 2340 pixel resolution, offering comparable clarity.
• Refresh Rate and Smoothness: A key differentiator is the refresh rate. The Galaxy A51 operates at a standard 60Hz refresh rate. The Galaxy S22 Plus 5G boasts an adaptive 120Hz refresh rate, which dynamically adjusts based on content, resulting in noticeably smoother scrolling, more fluid animations, and a more responsive feel during gaming or general navigation.
• Brightness Levels: The Galaxy S22 Plus 5G offers significantly higher peak brightness, reaching up to 1750 nits, which greatly enhances outdoor visibility and improves HDR content viewing. The A51's display, while good for indoor use, will not match the S22 Plus 5G's performance in bright sunlight.
• Screen Protection: The Galaxy A51 features Corning Gorilla Glass 3 for screen protection. The Galaxy S22 Plus 5G is equipped with the more advanced Gorilla Glass Victus+, providing enhanced durability against drops and scratches.

The camera systems on the Galaxy A51 and Galaxy S22 Plus 5G reflect their different market positions, with the latter offering a more advanced and versatile photography experience.

• Rear Camera System: The Galaxy A51 features a quad-camera setup, including a 48 MP main sensor, a 12 MP ultrawide, a 5 MP macro, and a 5 MP depth sensor. It performs well in good lighting conditions, capturing decent detail and vibrant colours. The Galaxy S22 Plus 5G comes with a triple-camera system that includes a 50 MP main sensor with optical image stabilisation (OIS), a 12 MP ultrawide lens, and a 10 MP telephoto lens with OIS and 3x optical zoom. This setup provides superior image quality, especially in challenging lighting, and greater flexibility for different photographic scenarios.
• Low-Light and Everyday Photography: The S22 Plus 5G excels in low-light conditions due to its larger sensor and OIS on the main and telephoto lenses, producing brighter, clearer images with less noise compared to the A51. For everyday photography, the S22 Plus 5G offers more consistent detail, dynamic range, and faster autofocus.
• Video Recording Quality: Both devices can record video at 4K resolution at 30 frames per second (fps) with their main cameras. However, the Galaxy S22 Plus 5G elevates video capabilities significantly, supporting 8K recording at 24fps and 4K recording at up to 60fps, along with advanced stabilisation features.
• Front Camera: The A51 has a 32 MP front-facing camera. The S22 Plus 5G features a 10 MP front camera with Dual Pixel PDAF, which offers faster and more accurate autofocus for selfies and video calls, and can record 4K video at 30/60fps.
• Audio and Speakers: The Galaxy S22 Plus 5G includes stereo speakers, providing a more immersive audio experience for media consumption. The A51 has a single bottom-firing speaker. The A51 also retains a 3.5mm headphone jack, which is absent on the S22 Plus 5G.
