Part 1: Three Reasons Cause Your iPhone 11/12/13 Won't Turn On

As mentioned above, there are several reasons why your iPhone 11/12/13 won't turn on. Below, we'll dig deeper into these causes to better grasp what may have caused your iPhone to be dead.

Power Problems

power issues

Three possible power problems might cause your iPhone not to turn on. Check them out below.

  • Battery Discharged

Check if your iPhone has been completely discharged. When the battery is too low to power on, the iPhone usually displays a screen prompting you to plug it in. But if the battery is extremely low, there may not be enough energy to power the display. Before ruling out battery discharge, plug your phone into a known functional charging setup for 10 minutes.

  • Bad Battery

Smartphone batteries degrade over time, allowing them to hold less and less charge. If you've been charging your iPhone many times, your battery may have degraded to the disabled point.

Furthermore, lithium-ion batteries, such as the one in your iPhone, dislike being fully charged or fully discharged . If you've kept your iPhone at one of these extremes for several weeks or months, the battery life may have suffered significantly, even if your charge cycle count is low.

  • Damaged Charging Port

Many iPhones' charging ports can become damaged due to wear from plugging and unplugging charging cables, especially if you aren't gentle with the port. If the port is damaged to the point where the contacts break, the phone cannot be charged via cable. In this case, your phone will no longer turn on because it has been discharged.

If your phone has wireless charging capabilities, try using a wireless charging pad to see if it will power up. If your phone turns on, you'll need to replace the charging port, which is usually located on the device's daughterboard. Find the daughterboard guide on the page for your specific iPhone and follow it to replace the charging port.

Physical or Liquid Damage

When your iPhone is dropped on the ground or in water, several things can go wrong, the most annoying of which is that the device does not turn on. You may still get a black screen, no matter how hard you press and hold the sleep/wake button. Although your iPhone is designed with fall-proof and water-proof materials to protect it, the materials cannot guarantee 100% security.

Another reason might be a damaged motherboard. Typically, the motherboard fails only after a significant impact, exposure to water, extreme temperatures, or changes to the BIOS settings (like when a jailbreak attempt is unsuccessful). If you suspect any of the above have damaged your motherboard, you may need to replace it to restore your phone's functionality.

Software Crashes

If your iPhone stops working for no apparent reason, i.e., you haven't exposed it to water, dropped it, or sustained other damage since the last time you turned it on, the most likely cause is a firmware crash. Force restart on your iPhone can get out of a bad firmware loop.

Part 2: 6 Ways to Fix iPhone 11/12/13 Won't Turn On

Below are some diagnostic ways and tips you can do to help you fix your iPhone 11/12/13 that won't turn on.

Force Restart Your iPhone

If the issue is caused by the iOS software freezing or crashing, you can force restart your device to resolve the iPhone Won't Turn On problem.

To Fix iPhone 11/12/13 that Won't Turn On:

  1. Press and quickly release the "volume up" button
  2. Then press and quickly release the "volume down" button, followed by the side button.
  3. Release the button to see the Apple logo.

Check iPhone Screen Display

If your iPhone screen is not working, there might be a problem with your device's screen display. There are two possibilities: your display cable has been disconnected from the logic board, or your screen has become damaged. Both can happen if you drop or knock on your iPhone.

If you drop your iPhone, the screen will likely be broken. If you have knocked it against something, the screen is very likely to be dislodged. If the screen is broken, you must replace it. If it becomes dislodged, you must reconnect the cable. The dislodged screen is repaired for free at the Apple Store.

Get Your iPhone Charged

As previously stated, your dropped iPhone not turning on is due to a depleted battery. It would help if you charged it in this case by plugging it into a wall charger. Check if your iPhone turns on after 30 minutes or an hour. Please check the cable if your iPhone is not charging.

Note: Ensure that your cable, charging block, and outlet are all operational for your phone to receive power.

Try Recovery Mode to Restore iPhone

Another solution is to enter your iPhone into recovery mode. Recovery mode can proceed with restoring your device by erasing your data. To do this, you can go with our steps:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button
  3. And press and hold the side button.

  1. After this, you have to exit your iPhone from recovery mode. Suppose you see the option to Restore or Update your device in Finder or the iTunes app, select Restore. Your device will exit recovery mode if it takes more than 15 minutes.

Perform DFU Mode

If Recovery mode restore does not work on your iPhone, your final option is DFU mode restore. It is not recommended because you risk bricking your iPhone if something goes wrong. That is why, if you are unsure, you should avoid taking the step. If you still want to go for it, here are the steps.

  1. Restart your computer and begin again. Using a lightning cable, connect your iPhone to your computer.
  2. While holding the Side button, press and hold the Volume Down button. If you see the Apple logo, you have failed and must release all buttons and begin again.

  1. If you don't see the Apple logo, release the Side button while holding down the Volume Down button.
  2. Once iTunes detects your iPhone, you can release the Volume Down button and follow the on-screen instructions to complete the DFU mode restoration process.

Note: If you see the message "Plug into iTunes" on your screen, it is not in DFU mode. You must restart from scratch. Let us reiterate that you can have the job done by an Apple expert who has used DFU mode before rather than you trying it for the first time.
