The Big Three Reasons “Your iPhone Won’t Turn On” And How to Fix This

When you use the iPhone for a long time, you will ask yourself  “Why my iPhone won’t turn on?”.  This is an emergency that makes most people crazy. We are all addicted to our iPhones. If your iPhone won’t start, before you tear all your hair out and scream at the next person you see, just take a deep breath. We are here to help.

This article will answer the following questions:

  • What should you do for a black or frozen screen?
  • What do you do if your iPhone is stuck on the Apple logo?
  • How do you tell if your iPhone is recharging?
  • What do you do for a software crash or corruption?
  • What is the liquid exposure indicator?
  • How do you solve other hardware problems?

Note: If your iPad won’t turn on or iPod won’t turn on, you can also fix this error same with iPhone device.

In addition, you can also refer to some articles about fixing the errors on your iPhone:

We compiled these helpful hints from official Apple resources and former technicians who worked at an Apple service center, in order to give accurate information about what you can do on your own and step-by-step instructions about how to do it. We included images and links to videos to make it easier for you to understand what to do.

Let’s Get Started

Before trying our suggestions, make an assessment of any serious damage. If your iPhone stopped working because it was damaged by liquid, was badly dropped, or has obvious physical damage, our suggestions may not work. You may want to try our suggestions first anyway; however, if your iPhone is damaged, you may have to take it to an Apple service center for repair.

For all other reasons, these methods are definitely worth trying to see if you can get your iPhone to start up again without taking it to an Apple service center for a potentially expensive repair. Some problems, which may seem serious, can be easily repaired. You will be really proud of yourself by learning how to fix these problems.

Before you read more insight into this error, I want to share my infographic for you. It’s will help you see the basic about the reasons and how to fix the iPhone won’t turn on. If you feel like it, I hope you will be sharing my infographic for everyone 🙂

The Big Three Reasons

Before you give up and take your iPhone to an Apple service center for repair, there are three big reasons why an iPhone will not start, which are:

  1. The software is corrupted or crashed.
  2. The battery needs to be recharged.
  3. There is a hardware problem.

1. Software

If the software is the problem, the first thing to do is to reset the software with a forced restart described in Section 1. If a forced restart fails, then the software needs to be fully restored back to default factory settings described in Section 5.

There are some third-party software tools, such as Dr. Fone and others such as those offered on TenorShare, which you can use to fix an iPhone that won’t start. These tools can help when there is a system crash due to a software corruption or problems with an iOS upgrade.

2. Battery

If you are able to see anything on your screen, there is some battery power. Even a blank screen does not mean the iPhone is off or the battery has lost its charge. It may just mean that the software crashed.

3. Hardware

If your hardware is the trouble and it is causing your iPhone not to recharge, you will need to go through a series of checks and then take the remedial steps necessary to get your iPhone to work again.

If all else fails, for more serious hardware problems, you may have to bring your iPhone to the nearest Apple service center for tech support.

What Do You Do When Your iPhone Won’t Turn On?

It is best to follow our directions in this guide in the order of the sections, which are:

1 – Force a Restart

2 – Charging Problems

3 – Back Up Data

4 – Hardware Problems

5 – Reset to Factory Default Settings

Hopefully, this will help you to get your iPhone working again on your own.

Section 1 – Force a Restart

If you have a black screen and your iPhone will not turn on in a regular way, Apple recommends trying a forced restart.

Here are the things to do to accomplish a forced restart depending on your iPhone model:

iPhone models 8, 8 plus, X, XS, XS Max, and XR

Force a restart on iPhone X

  1. Find the Volume Up Button, press and then immediately release it.
  2. Find the Volume Down Button, press and then immediately release it.
  3. Press and hold down the Side Button until the Apple logo appears on the screen.

iPhone models 7, 7 plus

Force a Restart on iPhone 7 plus

 

  1. Press and hold down both the Power Button and the Volume Down Button for at least 10 seconds or more.
  2. Hold the buttons down until the Apple logo appears on the screen.

iPhone 6s and earlier models

Force a Restart on iPhone 6s

  1. Press and hold down both the Home Button and the Power Button for at least 10 seconds or more.
  2. Hold the buttons down until the Apple logo appears on the screen.

If a forced restart gets your iPhone working again, congratulations! You just saved yourself an expensive tech support repair bill.

If, after following these instructions to force a restart, your iPhone is still not yet working, the next thing to do is to check the battery power available and to see if your iPhone is recharging properly.

Section 2 – Charging Problems

If your iPhone has a charge or can be recharged, you can skip this section and move on to Section 3 – Back Up Data. This will give more help if you are still experiencing difficulty to see if you can uncover other problems.

If your iPhone still won’t start up after trying a forced restart, this may mean the battery needs a charge. If the battery is completely dead, you may not see anything on the screen.

Should you replace the battery?

No, not really. It is possible; however, it is extremely unlikely that an iPhone’s battery is the problem. It is more likely that problems come from the lightning connection cable or power adapter. These may be preventing the iPhone from recharging. Check them first, instead of replacing an iPhone battery. Also, it is the software, not the battery, which decides if the battery should be charged.

Connections, Charging Port, Cable, and Power Adapter

Here are the steps to take to make sure your iPhone is properly connected to a power source and it is able to get the power needed to recharge it:

1. Recharge your iPhone’s battery

Recharge iPhone battery

Plug in your iPhone to recharge it for an hour. After a few minutes, you should see the charging screen.

2. iPhone is not connected to a power source

If the charging screen shows, flashes three times and then goes off, this means the battery charge is very low and the iPhone is not connected to a power source for recharging. Alternatively, if you see the “connect to power” screen notification the iPhone is not connected properly to a power source.

3. Insert cleaning the charging port on an iPhone

To make sure your iPhone can recharge, check the charging port, the connector cable, and the power adapter. Make sure any USB ports used and the charging port on your iPhone are clean of debris and the lightning cable is firmly connected. Use a brand new toothbrush to clean out the charging port and USB port if needed.

4. Use a high-quality connection cable

Check the lighting connection cable for damage. If it is frayed or the connectors are damaged it may be time to get a new connection cable. Be sure to use a high-quality connection cable because cheap ones may not work properly.

5. Check your USB jack

If you are using a USB jack on a computer for a power connection, try the plug-in power adapter instead; Or you are using the plug-in power adapter, try a USB jack on the computer instead. If there is more than one USB jack available on a computer try the different ones to see if you can find one that works. Make sure the cable makes a good connection.

Be sure to use the main USB power port directly from the plug-in adapter or a USB slot from a computer. Do not use a USB slot on an extension device because the power flow may be diminished on the extension.

Will your iPhone still not charge?

If you try these steps and still your iPhone won’t turn on or charge, if possible, try a different connector cable and power adapter. Or as an alternative, use your connector cable and power adapter to charge someone else’s iPhone. If you cannot do this step on your own, you may have to go to an Apple service center to be able to try a different cable or adapter to figure out if these things are causing the problem.

If checking the charging connections, cable, and power adapter does not work, continue on to learn about correcting other software problems.

Section 3 – Back Up Data

If a forced restart and fixing charging problems got your iPhone to start up again, it is a good idea to make a backup of your iPhone’s data right now while you have a chance. Apple gives instructions about how you can back up an iPhone to a computer, to iTunes, or to the iCloud.

It is always good to have an up-to-date backup, just in case. You may need this backup of your data to use if a software corruption causes your iPhone to crash again.

Section 4 – Hardware Problems

Besides charging problems caused by hardware not working properly as we discussed in Section 2, here are some other hardware problems that can keep an iPhone from working properly.

Display Not Working

A common hardware problem is if your display is not working properly. You can check for this problem by plugging your iPhone into a computer and then going to iTunes to see if the computer can then recognize your iPhone through the iTunes interface. Using this method, the computer’s display will substitute for the iPhone’s display.

iPhone Display Not Working

If your computer sees your iPhone and it shows up in iTunes, immediately back up all of your iPhone’s data to iTunes for safekeeping. This will keep your data safe while you get your iPhone’s display repaired.

Maybe your iPhone does not show up in iTunes, try to force a restart as described in Section 1 while your iPhone is connected to a computer and to iTunes. If you see any error messages, write them down. If iTunes says you need to restore your iPhone, go ahead and allow this to happen.

Damage from Liquids

Your iPhone can be seriously damaged by coming into contact with water or liquids that contain water. This problem is so bad that Apple created a visible liquid contact indicator (LCI) that can be viewed by anyone to see if the iPhone has been in contact with water or a liquid that contains water.

The LCI display is normally white or silver. When an iPhone comes into contact with water or a liquid, like coffee, which contains water, the display turns bright red. If your LCI is red, you have a serious problem.

iphone 6 Liquid Contact IndicatoriPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus

You can check LCI for your iPhone models at Apple Support

An LCI will not activate due to humidity. An LCI activates from more serious exposure to water, like dropping your iPhone into the toilet. You may need to use a magnifying glass and hold your iPhone under good lighting to see if the LCI changed to a red color.

Apple warranty will not cover damage of this kind, so you will have to pay out-of-pocket to have the damage fixed. You may even need to buy a brand new iPhone. Water is very dangerous to an iPhone. Keep yours away from water as much as possible.

Section 5 – Reset to Factory Default Settings

If you tried everything else and still your iPhone will not start then this is the last thing you can try. If you can, back up your iPhone first.

WARNINGS

PLEASE NOTE: Taking these steps restores the iPhone to the factory default settings and you will lose all of your data and preference settings. Only try this method after you have already tried everything else. This method will work even if your iPhone will not charge because you will plug your iPhone into a computer and use the computer power to do this restore procedure.

Using this method will erase all of the software that controls the iPhone’s functions, memory, and the firmware that controls the hardware. If your iPhone is damaged, there is the possibility that something can go wrong while attempting this procedure, especially if it has water damage.

If an iPhone has water damage, it may still be working; however, using this method to fix a minor problem may cause an iPhone to stop working completely. This happens because attempting a complete restore to factory defaults may not finish properly when the restore procedure encounters damaged hardware. Again, only use this method as the very last resort.

Device Firmware Update

This deep restore method is called a device firmware update (DFU). This method comes from a former Apple technician who performed it hundreds of times to bring an iPhone back to life when all other attempts failed.

5. Continue to hold the Home Button down.

6. Keep holding the Home Button down until iTunes shows a screen that says “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.”

7. When you see this screen on the computer, release the Home Button.

8. The iPhone screen should go black if it is not black already.

9. If the iPhone screen is not black at this point, you did something wrong and you need to start again from the beginning.

10. If the iPhone screen is black, you have entered the DFU deep restore mode. Click the OK button on the iTunes screen that says “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.”

11. Restore your iPhone with iTunes.

Conclusion

We do hope you succeeded with our helpful tips on how to fix problems when your iPhone won’t turn on. If you succeeded, you should congratulate yourself because you did what the Apple Genius repair techs do and you saved having to pay a big repair bill.

If you tried all these steps and still your iPhone won’t turn on at all, there is no other easy way to recover your data. Unless you had the good sense to back up your iPhone data on iTunes, the iCloud, or on a computer, it is probably all lost. The only other option is if you are willing to pay a very high price for specialty recovery services like the kind the FBI uses to recover data in a criminal investigation.

An iPhone that does not get fixed by the methods we suggested is broken in a serious way. It needs to be taken to an Apple Service Center to see if there is any way to fix it and, unfortunately, it may be cheaper just to buy a new one.

We know your iPhone means a lot to you just like ours does to us. If you like what we had to say, found it helpful, or can add anything, tell us what you think in the comments and share this article with others.
