1. Charge Your iPhone

Upon noticing your iPhone's failure to turn on, the first suspects are the charging process and the battery. Maybe it is an empty battery or a faulty USB cable or adapter. It could also be a slight software glitch that's causing it not to turn on even on a full battery. Fortunately, connecting the iPhone to a power source can be enough to eliminate this issue.

Steps:

  1. Plug in your iPhone and wait a few minutes to see if the charging interface pops up. If you see it, it means your iPhone is okay.
  2. If step one doesn't work, try charging with a different USB cable and power adapter. Your iPhone may fail to charge because your charger is faulty. Ensure you inspect the cable and adapter for any signs of physical damage.
  3. You can also unplug the iPhone from the charging socket and power it by connecting it to a computer.
  4.  Charge your iPhone.

2. Force Restart Your iPhone if it Has a Broken Screen

Here, it would help if you ascertained whether a dead screen is a culprit. Ask someone to call your iPhone and check if it rings. If it does but the display remains dark; you may need to replace the screen. But before that, you should force reboot the iPhone for a quick fix. All processes boot up to start afresh, which solves minor software errors and could be your solution.

Steps:

The steps you need to take to force restart your iPhone depend on the iPhone's model.

  1. Press and immediately let go of the Volume Up button.
  2. Repeat step one for the Volume Down button.

5. Via DFU Mode

DFU means Device Firmware Update. This is the deepest method of restoration to perform on an iPhone, allowing more changes than recovery mode. When in DFU mode, you use iTunes via a computer to reload every bit of code on your iPhone and its firmware. Doing so is irreversible, and you risk making the iPhone totally unusable. Thus, this method is a last resort to rule out software errors.

Steps:

  1. Connect the iPhone to your computer, then open iTunes if you are using a PC or a Mac running on macOS Mojave or earlier. Supposing you are using a Mac operating on macOS Catalina or newer, open Finder.
  2. Put the iPhone in DFU Mode.

    For iPhone 8 to iPhone 14:

    1. Quick press the Volume Up button, then quickly press the Volume Down button, and then long press the Side button until the iPhone screen turns black.
    2. Once the screen is black, long press the Volume Down button while still holding the Side.
    3. Release the Side button after 5 seconds while still holding the Volume Down Wait for your iPhone to show up on iTunes or Finder.
    4. Once your iPhone appears on the iTunes app, let go of the Volume Down.

    For iPhone 7 or older:

    1. For iPhone 6s and below, long press the Sleep and Home For iPhone 7, press and hold your Sleep and Volume Down buttons. Hold the buttons together for 8 seconds.
    2. Now, release the Sleep button but keep pressing the other button ( Home or Volume Down) until your iPhone shows up in iTunes or Finder.
    3. Release the Home or Volume Down Your iPhone's screen should be entirely black if it has successfully entered DFU mode. If it isn't black, restart this process.
  3. Click OK on iTunes or Finder to restore your iPhone.
  4.  Restore your iPhone via DFU mode.
  5. Click Restore iPhone.

  • DFU mode is free to use.

Cons:

  • It erases all data on your iPhone.
  • If the restore fails due to physical damage, like water damage, your iPhone can become completely unusable.
  • This process can be complex.

6. Restore Your iPhone via iTunes

Many people consider this method to be ideal, but it has many limitations. For example, you must have synced your iPhone to iTunes before it refused to turn on. Alternatively, you may be required to enter your password. If you cannot fulfill any of the above conditions, iTunes will not register your iPhone, and you will be unable to restart it.

Steps:

  1. Connect the faulty iPhone to a USB cable and plug it into a computer.
  2. Open iTunes on your PC/Mac.
  3. Check whether iTunes recognizes your iPhone. You will notice a phone icon in the top left corner of your iTunes window when iTunes registers the iPhone. If you see the icon, you are in luck. It means your iPhone is powered on, and you will likely be able to back it up.
  4.  Restore your iPhone on iTunes
  5. Click on the Restore iPhone button.

7. Keeping Your iPhone at a Normal/Ambient Temperature

If your iPhone won't turn on and it's extremely hot or cold outside, the reason may be a temperature condition. Once your iPhone cannot regulate its internal temperature, it goes to sleep until it returns to its normal operating temperature. Hence, if your iPhone won't turn on, move it to a place with ambient temperature. The perfect temperature should be between 32°and 95°F (0°and 35°C).

Steps:

  1. Remove the iPhone from extreme temperature areas.
  2. Place your iPhone in ambient temperature.
  3. Let it rest for a while and when you feel its temperature is back to normal, try to reboot it.

8. Removing the Liquid

Water is a big enemy of electronics as it tends to cause some of your iPhone's components to fail. This may limit your iPhone from being able to power on and it’s important to remove the liquid to allow your iPhone to dry out.

 Remove the liquid to repair water damage.

Steps:

  1. Hold the iPhone horizontally so the water inside can pour out, then use a soft, absorbent cloth to dry the outside of your iPhone.
  2. Eject the SIM card to create a vent for dry air to blow into the iPhone. You may use a fan to blow cool air into the iPhone via the SIM card slot.
  3. Lay the iPhone in a flat place in a dry location.
  4. Put desiccants on your iPhone. These are tiny little packets often shipped with items like electronics and clothes. They create a state of dryness in other items.
  5. Let the water evaporate. Apple recommends waiting up to five hours, but if possible, wait for 24 hours.
  6. Try turning your iPhone on again. If you waited 24 hours, connect it to a power source before restarting it since the battery is likely dead.
  7. If your iPhone turns on, back, it up immediately since water damage spreads and it could experience more problems later.

9. Contact Apple Repair Shop

If your iPhone's issue still persists, it is likely it got dropped, punctured, crashed, or has internal water damage. Contact an Apple repair shop for professional help as they can fix it, whether it is the CPU or motherboard. But, this should be your last option since it is more expensive and takes longer.

Contact Apple support.

Steps:

  1. Check how much it will cost to repair your iPhone before going to the shop.
  2. If you decide to go to the repair shop, back up your data, then connect to the Apple repair shop.
