Let’s get started.
Diagnose the problem
Your iPhone can fail to turn on due to out of battery, hardware, or a software problem.
- Your iPhone runs out of battery or there is something wrong with the lightning cable or port, so it is unable to get charged
- There is a software problem with your device for preventing the screen from turning on.
- There is something wrong with the hardware of your phone.
To effectively repair your iPhone and get it to start, choose the corresponding solutions according to your situation.
If your iPhone is out of battery, try the following
The following basic troubleshooting actions will help you power on your iPhone:
1. Check to see if you can restart the phone
Unless you deliberately turned off your iPhone in the Settings app, your iPhone may still be powered-on even though the screen is black. A simple software glitch could be preventing your device from turning on fully. The easiest way to remedy this situation is to hard reboot your iPhone.
If the force restart is successful, then the problem has been solved. But sometimes the problem can recur. If this happens, then it is likely that there is an app that is not functioning properly or coms corrupt data on your iPhone that keeps interfering with its proper function. In this case, the best thing you can do is reset your iPhone to its factory settings which can be done in your iPhone’s settings.
2. Check your lighting cable and your charger
When your device fails to turn on, you may need to charge the phone using another cable and another charger. You can also try charging someone else’s device using your cable and charger. If their iPhone charges but your iPhone won’t, try connecting the charger directly to a wall outlet rather than a computer.
Some people find that their devices charge better when connected to a wall charger even with the same cable. You can also try using a different port on your computer if you have been using a wall charger.
3. Try charging your phone
Once you’ve checked the cable and charger and found a charging system that works for you, connect your iPhone to the charger and let it charge for at least an hour or two. If it still not turning on, try the following ways.
If it is a software issue, try the following
If on the other hand your iPhone is charging very well, but won’t turn on, then it is most likely a software problem. In this case, try the following solutions;
1. Force restart your iPhone
The simplest and sometimes the most effective solution when your device is experiencing software problems. Here’s what you need to do to restart your iPhone, depending on your iPhone model:
- iPhone 8 and later: Press and then quickly release the Volume up button. Do the same with the Volume Down button and then press and hold the Side Button until you see Apple Logo.
- iPhone 7 and iPhone 7 Plus: Press and hold the Side or Top button and the Volume Button at the same time until you see the Apple logo appear on the screen.
- iPhone 6s and earlier: Press and hold the Home and the Top (Side) buttons at the same time until you see the Apple logo appear on the screen.

If this process takes more than 15 minutes, your iPhone will exit recovery mode and you will need to repeat step 2 above to put it in recovery mode again.
Troubleshoot a hardware problem
If your iPhone will not respond to any of the solutions above, then it is likely that it may be experiencing a hardware issue. Hardware problems are significantly harder to diagnose and even harder to fix. Some of the likely hardware problems that can cause an iPhone to fail to turn on include the following:
- Water damage is a major cause of this issue. If your phone gets wet, several hardware components can be affected, causing your iPhone to fail to turn on.
- If you dropped your phone, you may damage the screen and other internal components which could result in your iPhone failing to start or even work properly.
- Hardware components on the iPhone have been known to fail due to manufacturing defects. This is rare but can happen particularly in newer models.
There is a very easy way to check if your iPhone’s components are damaged in any way. Just connect your iPhone to the computer and open iTunes, if it appears in iTunes and you can backup your iPhone, then it may not be damaged. But if iTunes will not recognize your iPhone, then it may be significantly damaged.
Turn to Apple
If you gave tried connecting your iPhone to iTunes and iTunes/Finder will not recognize your iPhone, then the problem may be too advanced to troubleshoot on your own. In this case, the best thing to do is to get a professional to fix it for you. In other words, it is time to make an appointment at the Genius Bar and have Apple Technicians take a look at your iPhone. They will diagnose the problem and let you know how much it will cost to repair your iPhone. You may be able to save on the repair costs if your iPhone is still under warranty.
