When your iPhone 7 fails to turn on or gets stuck during the startup process, it is easy to think that the device is more damaged than it is.
While it is possible that a hardware problem could be the cause, it is just as likely that a simple software issue could be to blame.
First, we would like you to know that this is a fairly common problem, meaning you are not alone and even more importantly, a lot of other users have successfully solved this issue.
Based on theirs and our experience, we have come up with some of the best solutions to help you fix an iPhone 7 that won’t turn on.
But before we look at these solutions, let’s begin by examining some of the main causes of this issue.
Why Does Your iPhone 7 Not Turn On?
There are a lot of reasons why your iPhone 7 is failing to turn on. The most common of these causes include the following;
App or Software Malfunction
The most common reason why your iPhone 7 may fail to turn on is due to a corrupt app or a software crash.
A corrupt or outdated software can wreak havoc on your device, causing all manner of problems with its function.
This is why it is very important to ensure that the software on your device is updated to the latest version.
Insufficient Battery Power
Your iPhone may also be unable to turn on if the battery power is insufficient or if there is some issue with the battery itself. This problem can occur when the device runs out of power completely.
In this case, the device may not even show that it is charging even when it is connected to a charger. You may need to let it charge uninterrupted for some time before attempting to turn it on.
Hardware or Liquid Damage
If this issue occurred immediately after you dropped the device or soon after it suffered some liquid damage, then the problem is likely caused by hardware damage to the device.
In this case, we don’t recommend that you try to repair the device yourself as you may cause more harm. Instead, consider contacting Apple support or bringing the device to an Apple Store to get some repair options.
The following are some of the solutions you can implement to try and fix an iPhone 7 that won’t turn on;
Perform a Force Restart
One of the most effective ways to try and get your device to respond again is to force restart it.
For an iPhone 7, press and hold the Sleep/Wake button and the Volume Down button at the same time. Continue to hold both buttons for at least 10 seconds or until the Apple Logo appears on the screen.
A force restart will not erase any of the data on the device or affect the function of the device in any way. It is therefore a simple, but often a very effective way to get the device working normally again.
Power On Your iPhone 7 for a While
Since this problem can also be caused by insufficient charge, you might also be able to get the device to power back on by simply connecting it to a charger.
Use the device’s original charger and allow the device to charge undisturbed for at least 30 minutes. Once you are certain that the device has adequate charge, try turning it back on.
If the battery is completely drained, you may want to leave it connected to the charger for at least 1 hour before attempting to turn it ob.
Here, we also recommend taking the time to make sure that the device and the charging port are not damaged.
Ensure that there is no dirt, dust, or debris in the charging port, and make sure that the power adapter, jack, and USB cable you are using are all in good condition.
You should also make sure that the iPhone is not overheating or swollen.
When charging your device, it is important to use the original (OEM) or compatible charger.
You risk further damaging the device when you use an incompatible charger, one that may not have the same amps, voltage, and plug type as the original one.
If you suspect that the cable and charger are damaged, you may need to replace them.
Force Restart While Plugged into Computer
If a forced restart and connecting the device to a charger don’t solve the problem, you can try to do both at the same time.
Hard resetting the device while it is plugged into a computer is one of the best ways to fix problems with a device that will not turn on. Follow these simple steps to do it;
- Step 1: Use a lightning cable to connect the iPhone to a power source such as a wall charger or your computer.
- Step 2: Then hard reset the iPhone by pressing the Power button and the Volume down button until the Apple Logo appears on the screen.
- Step 3: Release both buttons when the Apple logo appears and with any luck, the iPhone will turn back on.

Restore Your iPhone 7 in Recovery Mode
Another way you can restore the device to normal function is to put the device in recovery mode and use iTunes to restore it.
Before we share with you the steps, it is worth pointing out that you may lose some or all of the data on the device.
So, if you can, it may be a good idea to backup all your data before attempting this solution.
When you’re ready, follow these simple steps to enter recovery mode and restore the iPhone in iTunes;

- If not, update iTunes before moving on. This will prevent some of the iTunes errors that may arise from incompatibility issues.
- Step 2: When the device is connected, force restart it. You can do that by holding the Power and the Volume Down Keys at the same time. Keep holding down both buttons even after you see the Apple logo.

If the process takes more than 15 minutes, the iPhone may exit recovery mode and you will need to repeat the steps again.
Put Your iPhone 7 in DFU Mode
DFU (Device Firmware Update) is what you do what recovery mode fails. It is highly effective because it puts your device in a state that allows it to communicate with iTunes without locating the operating system or the iOS boot loader, making it the most ideal solution when the iOS system is the problem.
This is also why it is the most common solution for when you want to change the device firmware whether it is an iOS firmware downgrade or you want to install custom firmware as you would when jailbreaking the device. It is also a good way to fix an iPhone 7 that won’t turn on.
Follow these steps to put your device in DFU mode and restore it in iTunes;
- Step 1: Connect the iPhone 7 to the computer and then open iTunes if it doesn’t automatically open.
- Step 2: Turn off the device if it is not already off.
- Step 3: Then, press and hold the Power button on the iPhone for 3 seconds. While still holding on to the Power button, press and hold the Volume Down button.
- Step 4: Continue to hold both buttons for an additional 10 seconds. If the Apple Logo appears on the screen, it means that you’ve held the buttons down for too long and you may need to start all over again.
- Step 5: After 10 seconds, release the Power button, but continue to hold the Volume Down button for another 5 seconds. If you see the Connect to iTunes screen, you may have held the button for too long and you need to start all over again.
You will know that the device is successfully in DFU Mode when the screen remains black. A message will appear in iTunes, indicating that an iPhone in recovery mode has been detected. Follow the instructions in iTunes to restore the device.
