iPhone 15 Not Turning On? Here’s Why and What You Can Do

A non-responsive iPhone 15 can be a major source of inconvenience. This troubleshooting guide outlines potential causes for this issue and offers practical solutions to restore your device’s functionality.


Common reasons why an iPhone might fail to power on

  • Battery Depletion: A fully discharged battery is the most frequent cause of iPhone startup failure. Even minimal residual charge may be insufficient for the device to power on.
  • System Malfunction: Software glitches or crashes within iOS can disrupt the normal boot sequence, resulting in a black screen or a frozen Apple logo display.
  • Defective Charging Components: Malfunctions within the Lightning cable, power adapter, or the power source itself can impede the necessary power delivery, preventing the iPhone from turning on.
  • Hardware Failure: Internal component damage, often due to physical impact or liquid exposure, can compromise the iPhone’s functionality and hinder its ability to power on.
  • Temperature Extremes: Exposure to excessively high or low temperatures can trigger protective shutdown mechanisms in the iPhone, temporarily preventing it from powering on.
