What Causes My Iphone 15 Overheating?

1.Third-party Apps Update Overload the CPU:

One of the primary culprits behind Apple iPhone 15 Pro Max overheating stems from the relentless background activities of third-party applications. Updates from these apps can inadvertently burden the device’s CPU, leading to increased temperature levels.

2.iOS 17 Software Bugs:

The software backbone of the iPhone 15, iOS 17, may harbor occasional bugs that contribute to overheating. These glitches can manifest in various forms, impacting the device’s thermal management and causing temperature spikes.

3.Using a Fast-Charge Cable:

Opting for a fast-charging cable, while convenient, can inadvertently escalate your iPhone 15’s temperature. The accelerated charging process generates more heat, especially if the device is simultaneously in use.

4.First Setup and Data Restoration:

During the initial setup or data restoration process, your iPhone 15 may undergo intensive background tasks. This transient but resource-intensive activity can lead to a temporary rise in device temperature.
