Problem

A Samsung Galaxy A52 has a weak or aged battery. In the available material, battery replacement is described as feasible but moderately difficult because the back cover and battery are glued. After opening, the original water and dust resistance cannot be reliably restored.

Possible diagnosis

The information indicates a worn smartphone battery. There is no reliable diagnosis for further damage. If there is swelling, heat, odor, liquid damage or deformation, the device should no longer be used and should not be opened by the user.

Is repair worthwhile?

Economic viability is uncertain. It depends on the condition of the device, the exact variant, replacement part quality and the cost of a professional repair. Device replacement is not expressly recommended by the available information.

When to use a professional

If the device is swollen, hot, damaged or wet, a specialist workshop or Samsung Service should be used. Lithium-ion batteries can catch fire or vent gas if punctured, bent, overheated or short-circuited. A swollen battery is a safety risk and should not be removed by laypeople.
