Samsung Highlights Safety Guidance Amid Reports of Swollen Batteries in Older Galaxy Phones

Following user and repair-community reports of battery swelling on select older Galaxy models (e.g., Galaxy S10, Note9, and mid-range devices from 2018–2019), Samsung’s official support guidance reiterates best practices for lithium-ion safety and directs users to authorized service centers for inspection and replacement.

Warning Signs & Immediate Actions

Why Older Models Are Affected

Lithium-ion batteries naturally age. Long periods at 100% charge, repeated exposure to heat, or prolonged storage can accelerate gas formation inside the cell. As legacy devices (2018–2019) remain in daily use across many regions, swelling reports tend to surface more frequently in community forums and repair shops.
