iPhone battery swollen: Dangers and Solutions to protect your device

A swollen battery in the iPhone is a problem that can affect various models, from the iPhone X to the most recent iPhone 17 Pro Max. This phenomenon not only compromises the phone's performance but also poses a safety risk to the user. At iServices, specialists in phone repairs, we explain everything you need to know to identify the associated dangers and the best solutions for this problem.

With the advancement of technology, lithium-ion batteries, present in all iPhone models, are more efficient, but they also require specific care to prevent malfunctions. A swollen battery can cause damage to the screen, the phone's structure, and even lead to dangerous situations, such as leakage of toxic material or fire. Fast and adequate intervention is essential to guarantee the safety of your device and the user.

Causes of a Swollen iPhone Battery

Prolonged Overcharging

When the iPhone is charged for many hours consecutively, especially with non-certified chargers, the battery can wear out prematurely. This overcharging causes an internal chemical reaction that leads to the battery swelling.

Exposure to High Temperatures

Lithium-ion batteries are sensitive to heat. Exposing the iPhone to very warm environments, such as in the car in the sun or near heat sources, can lead to battery expansion and degradation of its integrity.

Manufacturing Defects or Aging

Although rare, some battery batches may have manufacturing defects that lead to premature swelling. Furthermore, over time, the natural wear and tear of the battery can lead to deformation, especially in devices that have been in use for several years.

Physical Damage to the Phone

Falls or hard impacts can internally damage the battery, which can cause swelling or even electrolyte leakage. In these cases, the problem can quickly worsen if not addressed.
