  2. Unresponsive Buttons: Despite pressing the power button or any other buttons, there is no response from the device. No matter what you do, it remains unresponsive.
  3. No Vibrations: Usually, when an iPhone powers on, it produces a slight vibration. In the case of power-on issues, you won't feel any vibrations upon pressing the power button.
  4. No Apple Logo: Upon successfully turning on an iPhone, the iconic Apple logo appears on the screen. However, if your iPhone 15 won't power on, you won't see this logo at all.

Part 2: What Are the Reasons for New iPhone 15 Won’t Turn On

Encountering a situation where your brand-new iPhone 15 won't turn on can be disheartening. Several factors can contribute to this problem. These range from software-related issues to hardware malfunctions. Here are some of the most common reasons why your new iPhone 15 won't power on:

  • Battery Depletion: One of the most straightforward explanations for your iPhone 15 won't turn on could be a completely drained battery. If the battery has been fully discharged, the device won't respond to attempts to power it on until it is charged.
  • Software Glitches:Like any electronic device, iPhones can experience software-related hiccups. These can cause the device to become unresponsive. A corrupted iOS, failed software update, or an app conflict could be culprits.
  • Hardware Issues:Physical damage to critical components, such as the battery, power button, or charging port, can lead to power-on problems. Internal hardware malfunctions might also prevent the device from booting up.
  • Liquid Damage:Did your iPhone 15 come into contact with water or any other liquid? If yes, it can cause internal damage, leading to power issues.
  • Firmware Issues:Sometimes, there can be a problem with the device's firmware. This problem can prevent it from starting up correctly.
  • Overheating:If your iPhone 15 has overheated, it might go into protective mode. Thus, it can refuse to turn it on until it cools down.

  • Step 4: On your computer, iTunes/Finder should detect your iPhone 15 in DFU mode. You will receive a prompt with options to "Restore" or "Update." Choose the "Restore" option to reinstall the iPhone's firmware completely.
