Expert Review & Rating
Market Position in 2026
In 2026, the Samsung Galaxy M51 occupies a niche in the used smartphone market, primarily appealing to users prioritizing extreme battery longevity over cutting-edge performance or features. Its hardware, while capable in 2020, now positions it well below entry-level modern smartphones in terms of processing power and software support.
Performance & Daily Usage
Based on the Qualcomm Snapdragon 730G, daily usage in 2026 will likely be characterized by noticeable delays in application loading and multitasking. UI responsiveness, while initially smooth with One UI, will be hampered by the older chipset and limited Android 12 software update. Thermal management is unlikely to be an issue for general tasks, but sustained demanding applications would quickly expose the processor’s limitations.
The Best Features
The most compelling feature of the Galaxy M51 remains its 7000 mAh battery. This capacity, even by 2026 standards, is exceptionally large and allows for extended periods of use without needing a recharge, making it ideal for users who are constantly on the go or have limited access to power outlets. The Super AMOLED Plus display, while lacking a high refresh rate, still offers vibrant colors and deep blacks, providing a pleasant viewing experience for media consumption. The inclusion of a dedicated microSDXC slot and a 3.5mm headphone jack also adds practical value for specific user needs.
The Compromises
The primary compromise of the Galaxy M51 in 2026 is its Qualcomm Snapdragon 730G chipset. This 8nm processor, while competent in 2020, struggles significantly with the demands of modern applications, complex websites, and any form of gaming beyond casual titles. The device is also limited to Android 12, meaning it misses out on several years of security updates and new Android features. The 25W charging speed is slow compared to contemporary standards, making full battery replenishment a lengthy process. Furthermore, the plastic build, while durable, lacks the premium feel and rigidity of glass or metal constructions found in many modern devices, even in the budget segment. The camera system, while offering a 64MP main sensor, lacks optical image stabilization (OIS), which can result in less stable video and more motion blur in challenging lighting conditions compared to newer phones.
Buying Advice
The Samsung Galaxy M51 is a viable option in 2026 for users on a very strict budget who prioritize unparalleled battery life above all else, especially for secondary device use or basic communication. However, for anyone seeking a primary smartphone with modern performance, up-to-date software, or a responsive user experience, newer budget or mid-range alternatives are strongly recommended.
Frequently Asked Questions (FAQs)
The Samsung Galaxy M51 is generally not recommended as a primary device in 2026 due to its outdated processor and limited software support. It may be considered only for specific niche uses, such as an emergency backup phone or for users who absolutely require extreme battery life and are not concerned with performance, available at a very low price on the used market.
Based on its hardware, the 64 MP main camera with an f/1.8 aperture and 0.8µm pixels, combined with the lack of OIS, suggests that its low-light performance would be significantly challenged in 2026. Images would likely exhibit noticeable noise and reduced detail compared to modern smartphone cameras.
