We decided to finally address this problem after coming across so many articles claiming to have the solution for the “iPhone won’t turn on” problem, but most of the information in these blogs is wrong.

Reasons For iPhone Won’t Turn On

The four most common reasons why your iPhone won’t turn on include the following:

Battery Failure: If the screen is completely blank, then you’re most likely dealing with a drained battery. But if you noticed that the iPhone turned off when there was still quite a lot of battery or that the battery is getting too hot to the touch, then battery failure may come into play. This is especially true if your iPhone is a little older as older batteries tend to have a problem holding on to charge. As a battery’s performance declines, unexpected shutdowns may occur more frequently.

Water DamageEven the smallest amount of water damage can mess with the internal components, causing the iPhone to turn off unexpectedly. If your iPhone fell in water at any time in the past, liquid damage may be to blame.

Physical Damage: In much the same way, if you dropped your iPhone recently, then the internal components may be damaged, causing it to shut down unexpectedly, The iPhone may also look like it is turned off when the screen is broken.

Software Issues: Your iPhone may also fail to turn off on due to software issues. Malfunctioning apps and problems with iOS updates have been known to cause this problem.

Try the Tips Below to Fix iPhone Does Not Turn On

The following are the solutions we recommend when your iPhone won’t turn on:

1. Check the Lighting Cable and Charger

Since this problem can be caused by a battery that is completely drained or one that won’t charge at all, the first thing we recommend you do is check the lightning cable and charger that you are using to charge the device. If you think that there might be something wrong with your lightning cable and charger, try using a different one.

It is also worth pointing out that sometimes the iPhone will not charge properly when connected to a laptop computer. Therefore, we recommend connecting the iPhone to a wall charger instead. Allow the iPhone to charge uninterrupted for up to 30 minutes to see if it will turn on.

2. Restart Your iPhone

Restarting your iPhone is one of the best ways to fix an iPhone that won’t turn on if the underlying cause is software related. This is because a restart will often erase some of the corrupt data that may be causing the issue.

You can try to do this even if the screen is completely blank. Just press the on/Off button at the top or side of the iPhone for a few seconds. If the device is on, you will see the “Power off Slider” appear on the screen. If it is off, it will turn on.

Step 1: Connect the iPhone to your computer and then open iTunes. You should see the iPhone’s icon in the top left region of the screen.

5. Put iPhone into DFU Mode

Your iPhone may also fail to turn on because it is stuck on the Apple Logo during startup. This typically happens when jailbreaking the iPhone or soon after updating the iOS. In this case, putting the device in DFU mode may help:

Step 1: Open iTunes and make sure that the iPhone is turned off before connecting it to the computer.

Step 2: Press and hold the Power button for about 3 seconds.

Step 3: Press the Volume Up button, quickly press the Volume Down button and hold down the Power button until the screen goes black. Don’t let go of the Power button, press the Volume Down button (Home button for iPhone 6 and earlier) and hold both buttons for about 10 more seconds. Open iTunes and follow the instructions.

Step 4: Release the power button, but continue to hold the Volume Down or Home button for 5 more seconds.

Please note that if you see the “connect to iTunes” message on the screen, you are in recovery mode and you need to start again.

If the screen remains black, you have successfully entered DFU mode. Follow the instructions in iTunes to fix the device.

6. Reset iPhone Proximity Sensor

Although this is rare, your iPhone may fail to turn on when there is a malfunction with the proximity sensor. This is the sensor that dims the iPhone’s screen when you hold it to your face. When it not working properly the screen may remain dark even when you’re not holding it up to your face.

Fortunately, you can reset it following these simple steps:

Step 1: Hard reset the iPhone and when the device restarts, the screen should be responsive enough.

Step 2:  Go to Settings > General > Reset > Reset All Settings.

This will not affect any of your data, but may very well fix the problem.

7. Is Your iPhone Still Not Turning on?

If after trying all the solutions outlined above, the iPhone still won’t turn on, there is a string likelihood that there is more going on that just software issues. Since it is never a good idea to try and repair the hardware components by yourself, we recommend bringing the device to the nearest Apple service center. Apple technicians will be able to help you even if your iPhone has suffered liquid damage or any other kind of damage to the hardware.
