Software crashes or freezes can prevent your iPhone 12 from turning on. These issues may occur due to conflicting apps, outdated software, or software bugs.

iOS update problems

Problems during the iOS update process can lead to an unresponsive iPhone. Failed updates or interrupted installations can cause the device to get stuck in a boot loop or not turn on at all.

Hardware-related issues

Faulty power button

A malfunctioning power button can prevent your iPhone 12 from powering on. This can occur due to physical damage, wear and tear, or internal component failure.

Water or physical damage

Water exposure or physical damage to your iPhone can cause it to malfunction, including the failure to turn on. Water damage can corrode internal components, while physical damage can disrupt the device’s power circuitry.

Other potential causes

There could be other less common causes for an iPhone 12 not turning on, such as a faulty charging cable or adapter, a defective Lightning port, or a malfunctioning internal component.

Troubleshooting Steps

Basic troubleshooting methods

Charging the device

The first step is to ensure that your iPhone 12 has sufficient charge. Connect it to a known working charger and let it charge for at least 15-30 minutes before attempting to turn it on again.

Force restarting the iPhone

If your iPhone 12 is unresponsive, try force restarting it. Press and quickly release the volume up button, then press and quickly release the power down button (side button or sleep/wake button) until the Apple logo appears on the screen.

Advanced troubleshooting methods

Checking the charging cable and adapter

Inspect the charging cable and adapter for any signs of damage or wear. Try using a different cable and adapter to see if the issue lies with the charging accessories.

Inspecting the Lightning port for debris

Sometimes, debris or dust can accumulate in the Lightning port, preventing a proper connection. Carefully inspect the port and use a clean, dry toothbrush or compressed air to remove any debris.

Connecting to a computer for diagnostics

Connect your iPhone 12 to a computer using a Lightning cable and open iTunes or Finder. If your device is detected, you may be able to perform additional diagnostics or restore your iPhone using these tools.

Resetting settings or performing a factory reset

follow the prompts to enter recovery mode. From there, you can choose to restore your iPhone, which may fix any software-related issues causing it not to turn on.

Restoring from a previous backup
