A Oneplus 13S back cover with rubber edges offers flexibility and impact protection, but exposure to excessive heat can sometimes cause deformation. The rubber material used in a Oneplus 13S back cover is typically made from TPU or silicone, both of which are heat-sensitive to a degree. When a mobile back cover is left in direct sunlight, inside a car, or near high temperatures for extended periods, the edges may soften or lose shape. However, a high-quality Oneplus 13S back cover is designed to withstand normal temperature variations without warping. Selecting a well-made Oneplus 13S back cover ensures durability and resilience even in mildly warm environments.

Manufacturers often treat the rubber components of a Oneplus 13S back cover with stabilizers to resist temperature-related damage. These treatments help maintain elasticity and prevent the edges from becoming brittle or stretched out. Still, continuous exposure to extreme heat can cause gradual wear over time. Users should avoid placing their Oneplus 13S back cover on hot surfaces or leaving it in direct sunlight for hours. The flexibility that makes rubber edges protective can also make them vulnerable to distortion under extreme conditions. Proper care and storage help maintain the Oneplus 13S back cover’s structure and performance longer.

In practical use, a well-engineered Oneplus 13S back cover will remain stable even during warm weather or extended phone usage. Rubber deformation is more likely in low-quality products that use cheaper materials. To ensure lasting protection, users should choose a Oneplus 13S back cover from trusted brands that prioritize material quality and heat resistance. Zapvi offers premium covers designed to handle everyday conditions while maintaining flexibility, grip, and form. With quality construction and responsible use, the rubber edges of a Oneplus 13S back cover can stay strong and durable for years.
