Battery swelling is one of the most dangerous and frustrating iPhone problems. It's not just a technical defect, but a real threat to the device's safety and even your health.

Why does my iPhone battery swell?
Lithium-ion batteries are susceptible to overheating, damage, and improper use. Common causes of swelling include:
1. Overheating
High temperatures trigger chemical reactions inside the battery, causing gases to form. The battery expands and becomes unstable.
2. Natural wear and tear
The battery's lifespan is 2–3 years. After 500 charge cycles, it gradually degrades, with swelling being the final stage of wear.
3. Using cheap chargers and cables
Low-quality accessories produce unstable voltage and overheat the power controller and the battery itself.
4. Mechanical damage
A drop or strong pressure can cause microcracks inside the battery cells.
5. Battery defect
This is especially common with cheap copies of batteries that are installed in “garage” workshops.
