Part 2. 60-Second Fixes to iPhone Won't Turn on

When your iPhone refuses to turn on, the first step is to check for any external issues that may be preventing it from powering up. These issues could be the result of something as simple as a faulty charger or a dirty charging port. Here are some quick fixes you can try.

Method 1. Charge Your iPhone Properly

The most overlooked issue is a completely drained battery. When your iPhone won't on, the first thing you should check is whether it's running out of power. If the battery is deeply drained, the screen may remain black for several minutes before showing the charging icon.

Step 1. Connect your iPhone to a certified charger and cable.

Step 2. Plug into a wall outlet, not a laptop USB port.

Step 3. Leave it charging for at least 30 minutes.

Method 2. Wait and Reboot iPhone

Sometimes, the issue could be a temporary software glitch that is preventing the iPhone from starting up. In such cases, wait for a few minutes and then perform a Force Restart. This does not erase your data, and it simply cuts and restores power to the processor to break a software loop.

For iPhone 8 through iPhone 17:

Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Side button until the Apple logo appears on the screen.

For iPhone 7 and 7 Plus:

Press and hold the Side button and the Volume Down button at the same time until you see the Apple logo.

For iPhone 6s and earlier:

Press and hold both the Home button and the Top button simultaneously until the Apple logo appears.

Method 3. Inspect Charging Port and Cable

If the Force Restart failed, the battery might be "deep discharged." However, the issue often isn't the battery, and it's the path the electricity takes to get there. A faulty connection can prevent your device from receiving power. In this case, it is suggested that you do some things.

• Check for dust, lint, or debris in the charging port
• Use a soft brush or wooden toothpick to clean gently
• Test with a different cable and adapter

Method 4. Check for Overheating or Physical Damage

If you have tried a Force Restart, verified your charger works, and the computer doesn't recognize the device, your iPhone likely has a hardware failure. Check the screen or back glass, and make sure whether there is physical damage. Or make sure whether the battery has reached the end of its chemical life after a long time of use.

Part 3. How to Fix iPhone 17/16/15/14 Won't Turn on

If external fixes don't resolve the issue, the problem could be internal, such as software corruption or system glitches. In this case, you may need to try software-related solution or seek professional assistance to address the issue further.

If your iPhone still won't turn on, or if it turns on but gets stuck on the Apple logo, you need to use Recovery Mode. It restores the device to normal from any state. However, this will erase all the data and settings on the device, which causes the inconvenience to you.

Step 1. On a Mac, open Finder. On Windows, open the iTunes.

Step 2. Connect your iPhone to a computer.

Step 3. Perform the Force Restart steps listed above, but do not release the Side button when you see the Apple logo. Keep holding it until the "Connect to Computer" screen appears.

Step 4. A window will pop up on your computer. Choose Restore. This will attempt to reinstall iOS, but erase your data.
