Furthermore, the charging cable itself can also impact phone heating. A damaged or worn-out cable can result in increased resistance, leading to higher power loss and heat generation. It is essential to regularly inspect and replace charging cables to maintain optimal charging performance and prevent overheating.

While phone usage alone is not the primary cause of heating issues, certain activities such as playing graphics-intensive games or using power-hungry apps while charging can put additional strain on the phone's components, consequently contributing to increased heat generation.

When the phone is being used intensively, it requires more power from the battery, which in turn leads to higher current flow. This increased current flow can cause the phone's internal components, such as the processor and display, to work harder, generating more heat. Additionally, prolonged usage during charging can restrict airflow around the device, further exacerbating the heating issue.

It is advisable to avoid using power-intensive applications or games while charging, especially if the phone is already experiencing heating issues. Allowing the phone to charge without any additional load can help dissipate heat more effectively and prevent potential damage to the device.
