Noticed that the back of your iPhone is pulling away from the screen? Or that it’s turning off unexpectedly? This could be a sign of battery swelling, a serious issue that affects many iPhones, especially as they age or are exposed to repeated charging cycles. In this post, we’ll explore what causes an iPhone battery to swell, why it’s important to address it, and how to keep your device (and yourself) safe.

Why Do iPhone Batteries Swell?

iPhones use lithium-ion batteries, known for their efficiency and ability to be recharged repeatedly. However, when a lithium-ion battery starts to malfunction, gases can build up inside, causing it to swell and push against the phone’s components. Here are a few common causes:

1. Battery age: Older batteries have reduced capacity and stability, making them more susceptible to swelling.
2. Excessive heat: iPhones left in direct sunlight or warm environments for long periods can heat up, impacting battery health.
3. Improper charging practices: Overcharging (leaving it plugged in after reaching 100%) or using non-certified chargers can degrade the battery.
4. Physical damage: Drops or impacts can damage the internal structure of the battery, potentially leading to expansion.

Why Ignoring a Swollen iPhone Battery Is Risky

A swollen battery isn’t just a sign that your iPhone needs a repair; it’s a potential safety risk. Here’s why you should act quickly:

Fire hazard: While rare, swollen iPhone batteries can overheat and, in extreme cases, catch fire. The swelling indicates the battery is malfunctioning and unable to safely store energy.

iPhone damage: A swollen battery exerts pressure on the screen and internal components, possibly causing permanent damage to the device.

Step-by-Step Guide: What to Do If Your iPhone Battery Is Swelling

1. Power off your iPhone immediately: To reduce the risk of overheating, turn off the device as soon as you notice any swelling.

2. Avoid charging or using it: Do not charge the device or use it until the battery issue is resolved.

3. Don’t attempt DIY removal: Removing a swollen iPhone battery yourself can be dangerous. If punctured, it could release toxic chemicals or catch fire.

4. Visit an authorized Apple service provider: Apple’s technicians are equipped to safely handle and replace swollen batteries. You can schedule an appointment at your nearest Apple Store or authorized repair center for a professional assessment.

5. Dispose of the battery properly: Swollen batteries contain harmful chemicals, so be sure to recycle it through an electronics recycling facility.
