In this guide, we will explore how to detect and avoid a swollen laptop or phone battery, ensuring that your devices remain in optimal condition and safe to use.

Why Do Batteries Swell In Phones And Laptops?

Batteries in phones and laptops can swell due to several reasons, primarily related to the chemistry and usage of lithium-ion or lithium-polymer batteries:

  • Chemical Reactions -Over time, chemical reactions occur within the battery, leading to the gradual breakdown of materials. These reactions produce gases like oxygen and carbon dioxide, which accumulate and cause the battery to expand.
  • Heat and Overcharging - Exposure to high temperatures, whether during charging or usage, can accelerate these chemical reactions. Prolonged overcharging, where the battery remains connected to the charger even after reaching full capacity, can also contribute to heat buildup and swelling.
  • Physical Damage -Dropping or subjecting your device to physical stress can damage the battery's internal components. Even minor damage can compromise the battery's integrity, making it more prone to swelling.
  • Manufacturing Defects -In some cases, batteries may have manufacturing defects, such as internal shorts or impurities in the materials, which can lead to swelling issues.
  • Age and Wear -Like all components, batteries degrade with time and usage. As a battery ages, its ability to hold a charge diminishes, and this aging process can make it more susceptible to swelling.
  • Poor Quality Chargers and Cables -Using low-quality or counterfeit chargers and cables can stress the battery and lead to issues with swelling and overheating.
  • Software or Firmware Bugs -Rarely, software or firmware issues in the device itself can affect how the battery is managed, potentially leading to irregular charging or overheating, which may contribute to swelling.

How Would I Know If My Device Has A Swollen Battery?

These days, it's much harder to tell if your phone's battery is getting bigger because phones with batteries that can be taken out are becoming very rare. We don't see our batteries much anymore. This makes it harder to tell if a battery is swollen or broken.

One of the most apparent signs of a swollen battery is a visible bulge in the device's casing. Take a close look at your device, especially around the battery area. If you notice any abnormal protrusions or a slight curvature in the device's shape, it's likely an indication of a swollen battery. This visual inspection is a straightforward way to spot potential issues.

Additionally, you can conduct a stability test by placing your device on a flat, stable surface. If the device wobbles or rocks when you touch it, this could be a result of a swollen battery causing an uneven surface. This test can help confirm your suspicions.

Another telltale sign of a swollen battery is performance issues with your device. Keep an eye out for a sudden and significant decrease in battery life. If your device's battery drains quickly, it may be due to a swollen battery affecting its capacity. Frequent or unexpected shutdowns or reboots can also be a red flag. Furthermore, if your device becomes unusually warm during usage or charging, this heat buildup might be linked to a swollen battery. Lastly, erratic behavior such as apps crashing or the device freezing can be attributed to battery-related issues.

Many modern laptops and smartphones come equipped with battery health monitoring apps. These apps can be invaluable for assessing your battery's condition. Check these applications for information on battery capacity and any warnings or notifications related to battery health. If your device's battery health app provides concerning data, it's worth investigating further.

Inspect your device for any visible damage, especially in the battery's vicinity. Cracks, deformities, or physical damage to the device's casing can contribute to battery swelling. This damage can be both a cause and an effect of a swollen battery, making it essential to look for any signs of wear and tear.

In rare cases, a swollen battery might produce unusual sounds or emit odors. If you hear hissing, or popping, or notice any unusual smells while using your device, take these auditory and olfactory cues seriously. Such signs can indicate a potentially dangerous situation, and you should immediately cease using the device and seek professional help.

Even something as easy as how well the battery works can be a dead giveaway. If your battery charges too slowly or doesn't stay charged for as long as it should, this could be a problem.
