June 16, 2023

It’s not just you whose iPhone 7 won’t turn on. A lot of people have this problem, which can be caused by a number of things, from minor program bugs to more major hardware problems. It can be annoying, but the problem can usually be fixed without having to pay a lot for fixes. The goal of this complete guide is to give you specific instructions on how to find and fix the issue so that you can use your iPhone 7 again. If you follow the steps in this piece, you will save time, money, and trips to the repair shop that aren’t necessary.

Simple Ways to Fix Hardware and Software Problems

It’s important to rule out some simple hardware and software problems that might be stopping your iPhone 7 from starting up before looking into more complicated options. These checks are quick and simple to do, and they might fix the problem right away.

1. Battery Trouble

A fully dead battery is one of the most common reasons why an iPhone 7 won’t turn on. The first thing to check if your gadget seems to be dead is whether the battery is completely dead.

What You Need to Do: Take a break and leave your iPhone 7 plugged in for at least 15 minutes. It can take a few minutes for the gadget to respond to charging when the battery is completely dead. Make sure you use a wall outlet instead of a USB port to charge the device. A USB port might not give the device enough power to charge properly.

2. Make sure the charger and adapter are working.

Maybe the charging cords are broken if your iPhone still won’t turn on after charging. If your cords and plugs are broken or not working right, your iPhone might not charge properly.

What to Do: Look for damage that you can see in your charging cord and adapter, like wires that are frayed or connections that are bent. See if the problem still happens when you use a different charge wire and adapter. If the problem goes away when you use a different charger, the first one was probably broken.

3. Look for damage to the liquid or the material

The performance of your iPhone can be greatly affected by physical damage or being submerged in liquid. If you drop your device or let water get into it, it might not start because of damage inside.

What to Do: Look over your iPhone for any cracks, dents, or signs of water damage that you can see. Before you try to turn on your device again after it has been wet, make sure it is completely dry. Putting a gadget that has water inside it to turn on can make the damage worse.

4. Restart the device hard

A small bug in the software can sometimes make your iPhone 7 unusable. Most of the time, a hard reset can fix these problems.

What to Do: Hold down the Power and Volume Down buttons at the same time to do a hard restart. Hold down both buttons for at least ten seconds, or until you see the Apple sign. This should make the device restart, which might fix the problem.

Problem-Solving Guides for Batteries

If the simple steps for fixing don’t fix the problem, you may need to look into problems with the battery. Here are some specific things you can try if the problem is with the battery in your iPhone 7.

1. Charge your iPhone the right way

If you charge your device and then it doesn’t work, make sure you’re charging it properly. If you charge the device through a USB port on your computer, it might not get enough power to turn on.

What to Do: To charge, use a wall plug instead of the USB port on your computer. Before you try to turn it on again, plug it in and let it charge for at least 30 minutes. Making the charge last longer can help make sure the gadget has enough power to turn on.

2. Restart by force If the battery is charged all the way down,

If the battery in your iPhone 7 is totally dead and the device won’t work even after charging it, you may need to force restart it to get it to work again.

What to Do: Do what was said about the hard restart earlier. Hold down the Power and Volume Down buttons at the same time for at least 10 seconds. It’s possible for this to wake the gadget up from a deep sleep and let it turn on.

3. Check to see if the battery is bad

After following all of the steps above, if your iPhone 7 still won’t turn on, the problem may be with the battery. Batteries lose their power over time. If the battery is broken or can’t hold a charge, it could stop your device from turning on.

What to Do: If your iPhone does turn on, check the battery health by going to Settings > Battery > Battery Health. If the battery’s health has gotten very bad (generally below 80%), it’s time to think about getting a new one. If you can’t get the device to turn on, take it to an Apple Store or an authorized service provider so the battery can be checked.

Solutions for Fixing Software Problems

The problem might be with the software if the hardware is working fine and the battery seems fine. Here are a few software-related fixes that should help you figure out what’s wrong.

1. Use iTunes or Finder to restore the device.

If your iPhone 7 won’t turn on, it might be because of a problem with the program. To fix the problem, you can try to recover your device using iTunes (or Finder on macOS Catalina and later).

What You Need to Do:

Hook up your iPhone 7 to a computer that has iTunes or Finder installed.

Start up Finder or iTunes and pick out your hardware.

You will see choices to either Update or Restore your iPhone if it is found.

Before you do anything else, try the Update choice. This will reinstall the OS without wiping your info. If that doesn’t work, try the “Restore” button. This will delete all of your info, but it might fix the problem.

2. Go into DFU mode by pressing the “” button.

You might need to use DFU mode to re-flash the device’s software if your iPhone 7 still won’t work after recovering it with iTunes or Finder.

What You Need to Do:

Open Finder or iTunes on your computer and connect your iPhone 7.

Hold down the Power button for three seconds.

For 10 seconds, hold down the Volume Down button while you press and hold the Power button.

Let go of the Power button, but hold down the Volume Down button for five more seconds.

If you did everything right, the screen will stay black, and iTunes or Finder will let you know that it found a device in recovery mode.

After that, you can try to restart or update the gadget.

3. Fix problems that could be caused by a bad iOS update

An iOS update that is damaged or missing parts can sometimes make it impossible to start up. You could fix the problem by restoring your iPhone 7 using iTunes or Finder if you think this is what happened.

How to Fix It: If you can, make a copy of your info before you fix your device. After that, do what was said earlier to recover using iTunes or Finder.

How to Fix Hardware Problems

If the software-based fixes don’t work, you might need to look into hardware problems. These are some common tech issues that could make it impossible for your iPhone 7 to start up.

1. Give the charging port a clean.

Things like dust and dirt can get stuck in the charging port, stopping it from working properly and leaving your iPhone inactive.

First, turn off your device. Then, use a soft, dry brush or compressed air to carefully clean the charge port. Make sure that nothing is blocking the charging port. If there is, it could stop charging and the device from turning on.

2. Press the power button and the home button.

If the Power or Home buttons on your iPhone 7 are broken or don’t work, the phone might not turn on.

What You Should Do: Look for any actual damage on the Power and Home buttons. Once or twice, press them to see if they work. The buttons might need to be fixed or changed if they’re stuck or not working right.

3. Look at the screen

Your iPhone might be on if it moves or makes noises, but the screen goes black. This could mean that there is a problem with the screen.

How to Do It: Shine a torch on the screen. If the screen is dim or the pictures are fuzzy, it may be broken and needs to be replaced. It might look like your iPhone won’t turn on if the screen isn’t working right, but it’s actually working fine.

In conclusion

Don’t worry if your iPhone 7 won’t turn on. Many different methods of debugging can help you figure out what’s wrong and fix it. First, look for basic hardware and software problems. Then, fix any power issues, fix any software problems, and check the device for any hardware damage that might be there. Before you start fixing, make sure you have a copy of your info.

If none of the steps above fix the problem, you might want to get help from a reputable repair service like MrFixVA. You can get your iPhone 7 back to full performance and use it without any problems if you get the right help.
