Imagine this: You're using your phone as usual, scrolling through social media or replying to messages, when you notice something odd—the back cover of your device seems to be lifting slightly. Or maybe your phone wobbles on a flat surface when you tap on it. At first, you ignore it, but then you realize your phone has been heating up more than usual, sometimes even shutting down unexpectedly. These could be warning signs of a swollen battery, a problem that shouldn’t be taken lightly.

As Carlcare, the official service provider for TECNO, Infinix, and itel, we’ve seen firsthand how swollen batteries can damage smartphones and even pose safety hazards. Let’s dive into what causes battery swelling, how to identify it, and why timely replacement with a genuine battery is crucial.

How to Identify a Swollen Battery

A swollen battery doesn’t always show visible bulging immediately, but there are some clear warning signs to look out for. Recognizing these early can prevent potential hazards and save your device from further damage.

One of the most obvious signs is your phone's back cover or screen lifting. If you notice that your device doesn’t close properly, has a slight gap, or seems like it's coming apart, a swollen battery could be the culprit. Since a swollen battery expands internally, it pushes against the phone’s frame, forcing the cover or screen to separate.

Another way to check is by placing your phone on a flat surface. If your device wobbles when you try to use it, it may indicate that the battery is expanding and pushing against the phone’s body unevenly.

Additionally, unexpected shutdowns or overheating can signal a battery issue. A swollen battery struggles to deliver consistent power, which may cause random restarts or excessive heating, even when performing basic tasks. This happens because the internal components are under strain due to the irregular power supply from the damaged battery.

In rare cases, you may even hear hissing or strange sounds coming from your phone. This is due to gas buildup inside the battery, which can be a serious warning sign that your battery is at risk of leaking or bursting. If you notice this, take immediate action.

What You Should Do Immediately

If you suspect that your TECNO, Infinix, or itel phone has a swollen battery, here’s what you should do without delay to ensure your safety and protect your device.

Stop Using Your Phone Immediately

A swollen battery is highly unstable. Continuing to use the device or attempting to charge it could worsen the swelling, cause leaks, or even lead to an explosion. The safest step is to power off your phone immediately and disconnect it from any charger.

Do Not Puncture or Press the Battery

Many users try to press down the lifted battery or check its condition by poking it—this is extremely dangerous. A swollen battery contains gases that, if released through puncturing, could cause a chemical reaction, fire, or even an explosion. Never attempt to squeeze or press the battery to force it back into place.

Avoid DIY Battery Replacement

Modern TECNO, Infinix, and itel smartphones are designed with built-in, non-removable batteries, which makes DIY replacement risky. Improper handling can cause further damage to your phone and expose you to harmful substances. Attempting to remove a swollen battery without the right tools and expertise can puncture it, leading to hazardous consequences.
