If your mobile phone’s back cover is bulging or if the screen is lifting slightly, stop using it immediately. This could mean that the battery is swollen. A swollen battery isn’t just a problem; it poses serious safety risks.
Understanding Swollen Batteries
Swollen batteries occur due to various reasons. They can be caused by overcharging, high temperatures, or simply old age. Lithium-ion batteries, which are commonly used in smartphones, can swell when they malfunction.
When a battery swells, it expands and can cause severe damage to the phone. This issue is not just cosmetic; it can affect the internal components of your device.
❗ Dangers of a Swollen Battery
A swollen battery can be dangerous. Here are some potential risks:
🔥 Can Overheat or Catch Fire
A bulging battery may lead to overheating. In extreme cases, this can result in fires.
💥 May Burst or Leak Harmful Chemicals
If a swollen battery bursts, it can release harmful chemicals. These substances can be dangerous if they come into contact with skin or are inhaled.
📱 Can Push Screen Out, Causing Display Damage
As the battery expands, it can push against the screen. This can lead to display damage, making the phone unusable.
⚡ Leads to Short Circuit or Total Phone Failure
A damaged battery can cause short circuits. This may completely disable the phone, requiring expensive repairs.
Even if the phone still works, continuing to use it risks both your safety and the device’s integrity. Mobile service centers often see cases where neglecting battery issues leads to more significant problems.
What to Do Instead
If you suspect your phone has a swollen battery, take the following steps:
Power Off the Phone
Turn off your device immediately to avoid any further risk.
Don’t Press or Puncture the Battery
Avoid pressing down on the battery or attempting to puncture it. This can make the situation worse and increase the risk of a fire.

Find a reliable technician for a safe battery replacement. It’s essential to address the issue promptly.
