Understanding the Causes of a Swollen iPhone Battery

There is no doubt that iPhones are equipped with the best smartphone batteries that have a long lifespan. iPhones use lithium batteries which have higher energy efficiency and are also lightweight, making them better than other battery types. However, what happens when your iPhone battery starts to swell abnormally?

A swollen battery issue can not only be frustrating but also dangerous. It can also cause significant damage to your phone's internal components. In this blog post, we will delve into what causes the iPhone swollen battery issue, how to identify it, and what you can do to prevent it. So, if you are an iPhone user, read on to learn more about this common issue and how to handle it.

Overcharging is one of the leading causes of a swollen iPhone battery. The problem with overcharging is that many users tend to leave their iPhones connected to chargers overnight or for extended periods without considering the potential consequences.

When a device is continuously charged beyond its capacity, it can lead to the accumulation of gases within the battery cells, causing them to swell. This excessive charging puts a strain on the battery and disrupts its normal functioning.

To prevent overcharging, it is essential to be mindful of your charging habits and follow manufacturer-recommended guidelines. Avoid leaving your iPhone plugged in for prolonged periods and unplug it once 80% or fully charged. Additionally, using genuine Apple chargers and cables can help ensure proper charging and minimize the risk of overcharging.

Being conscious of how you charge your iPhone can go a long way in preserving the health of its battery and avoiding potentially dangerous situations caused by overcharging.

Physical damage

Physical damage is another major cause of a swollen iPhone battery. Accidental drops, impacts, or any other form of physical trauma can result in internal damage to the battery cells. When the battery is compromised, it can lead to the release of gases and subsequent swelling.

The outer casing of an iPhone is designed to protect its internal components, including the battery. However, if the device experiences a significant impact or is subjected to excessive force, it can suffer structural damage that affects the battery's integrity. This damage may not be immediately visible but could lead to swelling over time.

Extreme temperatures

Extreme temperatures can also be a significant factor in causing a swollen iPhone battery. Both excessively high and low temperatures can disrupt the chemical reactions happening inside the battery, leading to internal damage and subsequent swelling.

When exposed to extreme heat, the electrolyte fluid inside the battery can expand rapidly, causing pressure to build up. This pressure can lead to swelling and even rupture of the battery casing. On the other hand, extremely cold temperatures can slow down the chemical reactions, potentially resulting in irreversible damage to the battery cells.

It is crucial to avoid exposing your iPhone to extreme temperature conditions. Do not leave your device in direct sunlight for prolonged periods or leave it in a car on a hot day. Similarly, avoid subjecting your iPhone to freezing temperatures or storing it in environments with extremely low temperatures.

Manufacturing defects

Manufacturing defects can also contribute to a swollen iPhone battery. In some cases, batteries are not manufactured properly, resulting in potential issues down the line. These defects can include inconsistencies in the battery's internal components, such as uneven cell construction or impurities in the electrolyte fluid.

When a manufacturing defect is present, it may disrupt the normal chemical reactions happening inside the battery, leading to instability and swelling. These defects can be difficult to detect initially but become evident over time as the battery undergoes charging and discharging cycles.

Unfortunately, manufacturing defects are beyond the control of individual iPhone users. If you suspect that your iPhone battery has a manufacturing defect and notice signs of swelling or abnormal behavior, it is essential to seek professional assistance from an authorized service provider or Apple store.

They will be able to evaluate the situation and determine whether a replacement battery is necessary. Remember that addressing potential manufacturing defects promptly can help prevent further damage and ensure the overall safety of your device.

REPART iPhone Battery

Repart is one of the highest quality iPhone battery manufacturers that produce batteries that are long lasting, safe, and efficient, as well as having a longer cycle life.


In conclusion, a swollen iPhone battery is not only frustrating but also potentially dangerous. Knowing the leading causes of this issue, as well as how to prevent it, can go a long way to keeping your device safe and in good working order. Remember to be mindful of your charging habits, handle your iPhone with care, and avoid exposing it to extreme temperature conditions.
