The Samsung Galaxy A57 5G was dissected almost immediately after its official launch, revealing a design that is both familiar and user-friendly for repairs. A teardown video by PBKreviews on YouTube shows the device’s internal layout and highlights improvements aimed at making battery replacements and heat management easier.
The Galaxy A57 retains Samsung’s typical assembly style: after warming the device, the rear cover comes off, followed by unscrewing the internal frame that secures the components. Internally, the motherboard is positioned on top, while the battery occupies most of the lower space. A key update is the battery’s securing method. The 5000 mAh battery now uses pull-tab adhesive strips, a repair-friendly feature that significantly eases removal and replacement compared to previous models.
Samsung has also enlarged the vapor chamber cooling system located beneath the battery. This upgrade improves thermal management, which could translate to better sustained performance and device longevity, especially given the increasing demands of 5G and multitasking.
Thanks to these thoughtful design choices, the Galaxy A57 earned a high repairability score of 9 out of 10-a rare feat for modern smartphones, which often sacrifice ease of repair for slim profiles and waterproofing. For context, this matches the excellent rating previously given to the flagship Galaxy S26, indicating that Samsung is placing more value on serviceability in its newer devices across categories.
Such repairability upgrades come at a time when manufacturers face growing pressure from consumers and regulators to improve device longevity and reduce e-waste. With Samsung tipping the scale back toward easier repairs, the Galaxy A57 may set a modest new standard in an industry where many phones remain difficult and costly to fix. Whether this marks a lasting shift or a rare positive exception remains to be seen as other brands continue to balance design and repairability.
