What Causes an iPhone to Crash?


Much like other electronic devices, your iPhone may be prone to crashing every so often. Sometimes the result of user error, software can also be the culprit in iPhone crashes. Usually, a simple restart should solve the problem, but sometimes the error is so severe that your iPhone requires significant repair. By identifying the causes of your iPhone crashing, you can prevent it from happening in the future and assist tech support in finding and remedying the issue.


  • Occasionally, Apple sends iPhone software updates via iTunes and the Apple website to enhance your iPhone's performance. These iOS software updates often include enhanced security and speed patches, but also contain stability patches to decrease freezing and crashing. While update software is typically rigorously tested, it can still cause crashing when downloaded to your phone because of your apps and settings. Luckily, you can usually revert back to a previous version of iOS if your update is causing crashes.

Application Overload

  • Your iPhone gives you access to the App Store, which houses hundreds of thousands of applications for entertainment, games, organization and functionality. Unfortunately, overloading your phone with running processes and applications can cause the applications to crash on their own. This usually results in the application shutting down when opened or a frozen screen and subsequent crashed iPhone. By closing applications not in use and getting rid of large, unused apps, you can keep memory space clear and your iPhone will crash less and operate faster.


  • While iPhone viruses are uncommon at time of publication, they still exist. Most iPhone viruses are actually created by security teams to test the vulnerability of the device, but hackers can also infect iPhones with viruses via SMS. Since there is currently no way to scan iPhones for viruses, a virus that makes your iPhone crash will need to be dealt with via Apple tech support. As technology becomes more advanced, so do viruses, which means it could become a larger problem as time goes on. Keeping your software up-to-date can also help with security patches to protect you from virus vulnerability.


  • Certain types of damage can clog and corrode the inside of your iPhone, resulting in overheating, slower processing, crashing and even a complete loss of functionality. Water is particularly damaging and is not covered by the Apple warranty. Water corrodes the inside of your iPhone, while dust and other debris can cause clogging and, subsequently, an iPhone that runs slowly and crashes frequently. You'll need to have your iPhone serviced and, in some cases, even replaced to fix the problem.
