ios 16 overheating

If an iPhone gets heated up to an uncomfortable level, it becomes a concern since high temperature can damage internal components and permanently shorten battery life.

In this article, we have listed some simple steps you can on your own follow to fix the issue of iOS overheating with no step skipped. Why is my iPhone overheating after updating to iOS 16?

Part 1: Why Does My iPhone Get Overheating after updating iOS 16?

There are quite a couple of reasons why iPhone devices get hot mostly after updating to the iOS 16 version of the operating system.

The first reason why you notice iPhone getting hot after the update is because iOS 16 is a very new version of iOS with a large file size of up to 5.3GB.

The bigger the update file, the more the load on the processor and other phone components playing different roles and the longer it takes to install the updates, and because of that, it’s going to take some time for your iPhone to get cold.

Importantly too, let’s attempt to look into other possible reasons why the iPhone gets hot apart from the large size of the iOS file update.

The following reasons may also cause iPhone to become hot:

  • 1. Been Left in a High-temperature Environment
  • If an iPhone is kept on a hot surface or within a high-temperature room for some time, chances are that the device will get hot.

  • 2. Faulty Battery
  • A faulty phone battery can release irregular power and cause overheating. Should you observe a notification to replace the battery, it is strongly recommended you heed the advice.

  • 3. Multiple Apps Running
  • Most times we open so many apps and just minimize them without remembering to close them. This act oftentimes makes iPhone get hot. This is because so many of the phone resources such as processor, power, memory, etc. are utilized to keep those opened apps running.

  • 4. Rigorous Streaming
  • Heavy streaming sometimes causes overheating of the iPhone because the processor, memory, and the GUI are over-utilized hence the power supply goes up to measure up with the level of phone engagement. 

  • 5. Software Bugs
  • Some bugs in either the operating system or the applications can also make the phone to be hot.
