Introduction
Your smartphone’s battery is one of the most important components of the device, yet it’s often the most overlooked—until something goes wrong. At Mobile World, we frequently encounter phones with swollen batteries, and many of our customers don’t realize how serious this issue can be. A swollen battery is more than just a sign of wear and tear; it can pose real risks to your phone’s functionality and, more importantly, your safety. In this blog, we’ll explain what causes a battery to swell, how you can spot the warning signs early, and what steps to take if you think your phone’s battery may be affected.
What Causes a Battery to Swell?
A swollen battery usually results from a chemical reaction gone wrong inside a lithium-ion battery. This can happen for several reasons, including overcharging, overheating, physical damage, manufacturing defects, or simply old age. Over time, these factors can cause gas to build up inside the battery’s sealed casing. Since the gas has nowhere to escape, it causes the battery to expand and swell. This swelling puts pressure on the internal components of your phone, sometimes forcing the screen to lift or the back panel to bulge outward. If ignored, this can lead to dangerous situations, including battery leakage or fire.
Common Warning Signs of a Swollen Battery
There are a few early indicators that your battery may be swelling. One of the most obvious signs is a screen that looks lifted or separated from the body of the phone. This is because the battery underneath is expanding and pushing the screen outward. You might also notice a bulge on the back of your phone or feel that it no longer sits flat on a surface—it might rock or tilt slightly. Additionally, a swollen battery can cause your phone to overheat, even when you’re not using it heavily. You may also experience rapid battery drain, unexpected shutdowns, or problems with the touchscreen becoming less responsive, all of which are red flags that shouldn’t be ignored.
Why You Shouldn’t Attempt DIY Battery Removal
It’s important not to try removing a swollen battery yourself. Many modern smartphones have non-removable batteries, and opening the device without proper tools and experience can cause more harm than good. Puncturing a swollen battery can lead to leaks, toxic fumes, or even fire. Likewise, continuing to use or charge a phone with a swollen battery increases the risk of further damage or injury. It’s also crucial to know that you should never dispose of a swollen battery in household trash. These batteries are considered hazardous waste and must be recycled safely.
