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.
