iPhone gets very hot and the battery drains quickly: causes and effective solutions

If your iPhone gets very hot and the battery drains quickly, know that you are not alone. Many users of models from the iPhone X to the latest iPhone 17 Pro Max experience this issue, which can compromise the user experience and the device's lifespan. At iServices, we understand how important it is to keep your iPhone in the best condition, which is why we have gathered essential information about the most common causes and recommended solutions for this problem.

These symptoms can occur for various reasons, ranging from intensive app usage to issues with the hardware or the operating system itself. Identifying the root cause of the problem is crucial to ensure your iPhone functions efficiently again, without overheating or excessive battery consumption.

Why does the iPhone battery get hot?

Intensive use of apps and games

Apps that require a lot of resources, such as games with advanced graphics or video editing apps, put a strain on the iPhone's processor, increasing the device's temperature and battery consumption.

Operating system updates in the background

iOS performs automatic updates and synchronizations in the background, which can lead to a temporary increase in heat and energy consumption, especially after a major update.

Battery or hardware issues

Degraded or defective batteries can lead to abnormal heating and rapid battery discharge. Additionally, damaged internal components can affect the iPhone's thermal performance.

Background settings and apps

Apps that continue to run in the background, constant notifications, and active location services can increase battery consumption and cause prolonged heating.
