iPhone Won’t Turn On in iOS 27? Here’s why (and what to do)

by Dave Johnson

Even the best smartphone is pretty useless if you can’t get it going. Luckily, we have solutions if your iPhone won’t turn on after iOS 27 update.

There is nothing new about the problem of iPhone not turning on as it has existed on almost all iPhone models. This problem has affected many iPhone models, including iPhone 17.

If your iPhone won’t turn on after iOS 27 update, read below to learn why and what you can do about it.

Why won’t my iPhone turn on after iOS 27 update?

Whether you’re rocking an older iPhone 11, or newer iPhone 17, nothing is more frustrating than a device that won’t turn on. Before you give up, there are a few fixable reasons your iPhone may not be powering up after iOS 27 update. If none of the problems below apply to you, it could be time to take your device in for a checkup at an Apple store.

The iPhone is out of battery

The most obvious reason for your iPhone not turning on after iOS 27 update is that the battery is dead. Luckily, this is the easiest solution to fix. On the iPhone 11 and newer, charging from 0—50% takes only 30 minutes.

Fast charging works when you use an Apple USB-C to Lightning cable or USB-C cable and one of these adapters:

  • Apple 18W, 20W,2 29W, 30W, 35W, 61W, 67W, 87W, or 96W, or 140W USB-C Power Adapter
  • A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

If you’re not sure which Apple Power Adapter you have, check the wattage on the top or bottom of the adapter.

Your charger isn’t working properly

If you left your iPhone to charge up and came back to a device that still won’t turn on, your charger may be the culprit. Faulty third-party chargers or even a worn-out one from Apple are worth replacing. There is also the possibility that the outlet you are plugging into isn’t supplying power.

Your iPhone is frozen

iPhones can sometimes freeze or get stuck on a black screen. Often, this is the result of an outdated version of iOS or a glitchy app.

How to get your iPhone to turn on again

If (fingers crossed) you’re facing a minor issue, one of the solutions below will likely help you get your iPhone turned back on. If your iPhone is completely shot, it may just be time to replace it.

Charge your battery

If your device’s battery is dead, you need to charge it. If iPhone is very low on power, it may display an image of a nearly depleted battery, indicating that it needs to charge for up to 10 minutes before you can use it. If iPhone is extremely low on power when you begin to charge it, the display may be blank for up to 2 minutes before the low-battery image appears. See our troubleshooting guide if your iPhone won’t charge.

To charge iPhone, do any of the following:

  • Connect your iPhone to a power source using the charging cable (included) and an Apple USB power adapter (sold separately).
  • Place iPhone face up on MagSafe Charger or MagSafe Duo Charger (connected to Apple 20W USB-C power adapter or other compatible power adapter) or on a Qi-certified charger. (MagSafe Charger, MagSafe Duo Charger, power adapters, and Qi-certified chargers are sold separately.) Note: You can also use third-party power adapters and Qi-certified chargers that are compliant with applicable country regulations and international and regional safety standards.
  • Connect iPhone and your computer with a cable. Make sure your computer is turned on—if iPhone is connected to a computer that’s turned off, the battery may drain instead of charge. Look for the Charging icon on the battery icon to make sure your iPhone is charging.

WARNING: If your iPhone won’t turn on as a result of water damage, don’t plug the charging cable into it.

Assess your cable, adapter and outlet

If your iPhone doesn’t turn on after trying the above solution, inspect your charging cable, charging adapter and power outlet.

We understand your iPhone stopped charging after iOS 27 update, but the cable is one of the first things to check. Especially if it’s an accessory you’ve had for a long time, possibly since the phone was purchased. Our cables go through plenty of torture. They go with you to many places, not to mention we can often step or trip on them, they often get tangled up, we throw them in bags carelessly, and so on.

Inspect your charging cable thoroughly and see if there are any evident signs of damage. Any rips, bends, cuts, or general damage will be a good reason for cables not functioning correctly. Also, try to charge another device with it and see if it works. If it does, the issue might be the device. You can also try using another cable to see if it will charge your iPhone battery.

If you find out a damaged cable is the issue, go ahead and get a replacement.

Of course, the charging adapter is just as important as the cable. Go ahead and put it through the paces. Inspect it for any damage. Cracks or bent outlets are obvious red flags. Likewise, try using it with other devices and switching it with another brick to see if this is the problem.

Finally, plug something else into the same outlet you’re trying to charge your iPhone with and see if it works. Sometimes outlets go bad, or a section of your home might have electric problems. Additionally, some power sources can be weak. If you find issues with your outlet, try other outlets in the house.

Those trying to charge using a USB port in a computer or power strip might not be getting the juice the iPhone needs to charge correctly. Move to a regular outlet and see if this gets rid of your charging woes.

Check your charging port

If your cable and charger work with other devices, it’s time to start looking at your phone. A common culprit is the charging port. For starters, go ahead and check if there is any dirt or debris in the charging port. Something as simple as a dirty port will mess up your charging. You can try cleaning the charging port with a brush or compressed air.

Have you noticed the charging port feeling loose lately? Charging ports can get worn out with excessive usage. You could also find signs of corrosion in there. Sadly, there isn’t much you can do about this, other than replacing the phone or trying to have the charging port replaced.

Force restart your iPhone

If your device doesn’t charge, force a restart. Your device may have frozen after iOS 27 update and could require juice once it powers up.

To force restart your iPhone, follow the steps below:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side button until the Apple logo appears.

    4. iPhone won’t turn on still? Contact Apple Support

    If you’ve tried the solutions above, and your iPhone will not turn on, it may have a hardware failure. At this point, your best chance to get your device working is to locate the nearest Apple Store. Apple store employees can help determine what the underlying issue is with your iPhone. If you don’t have an Apple Store nearby, you can also contact Apple for support and service.

    Successfully fixed iPhone not turning on issue

    If your iPhone doesn’t turn on after iOS 27 update, it might be dead or facing issues charging. Finally, you may need to force the device to restart. Let us know which of the above troubleshooting steps fixed your iPhone not turning on issue.

In general, you can narrow it down to one of three key issues: an iOS 26 glitch, a charging malfunction, or a serious hardware problem.

Here’s how to figure out why your iPhone is not turning on after iOS 26 update and how to fix it.

How to turn on an iPhone

You need to make sure you’re turning on your iPhone the right way before trying any of the troubleshooting steps mentioned below.

Press and hold the Power button (which is on the right side. After a few seconds, an Apple logo should appear on the screen.

What to do if your iPhone won’t turn on after iOS 26 update

Once you’re sure that you can switch on your iPhone properly, you can try to get to the bottom of why it’s not turning on.

1. Force your iPhone to restart

The first thing you should do if you’re iPhone won’t turn on after iOS 26 update is forcing it to restart.

  1. Quickly press and let go of the volume up button.
  2. Quickly press and let go of the volume down button.
  3. Press and hold the side button until the Apple logo appears on the screen. Then let go.

If your phone restarts successfully, your problem is solved. It’s safe to say that a minor iOS 26 glitch was preventing your iPhone from turning on properly. If your iPhone doesn’t turn on, move onto the next solution.

2. Try charging your phone

If your iPhone doesn’t turn on, it’s possible the battery is completely dead. Here’s what you should do:

  • Plug your iPhone to a power source and let it charge for one hour.
  • Force restart your iPhone.

If your iPhone shows a low-charge battery, there might be something wrong with the way it’s charging. Check the phone’s USB-C port to make sure it isn’t filled with lint or debris, and check your charging cable and USB adapter for signs of damage, like breakage or bent prongs. Don’t use damaged accessories. If necessary, swap the cable and USB adapter for another.

Charge your iPhone again for 30 minutes or until it starts. Be sure to plug the phone directly into a wall outlet rather than a computer’s USB port, to make sure the the phone is receiving enough power supply.

It’s entirely possible that the USB-C port or your laptop’s USB port has failed, and since it wasn’t charging, you couldn’t turn it on. If so, this should solve your problem.

Quick tip: if the problem still persists, there are more troubleshooting steps you can try to fix an iPhone that won’t charge after iOS 26 update.

3. My iPhone can’t turn on past the Apple logo screen

If your iPhone turns on but gets stuck on the Apple logo screen, connect your device to a computer, then put your phone into recovery mode with these steps:

  1. Quickly press and let go of the Volume Up button. Quickly press and let go of the Volume Down button. Press and hold the Side button. Keep holding the Side button until you see the recovery mode screen.
  2. On a Mac with macOS Catalina 10.15 or later, open the Finder. On a Mac with macOS Mojave 10.14 or earlier, or on a PC, open iTunes. When asked to update or restore, choose Update. This will update your device to the latest version of iOS 26. If you choose Restore, it will erase your iPhone.

4. Troubleshoot a hardware problem

If your iPhone still won’t turn on, you might be dealing with a hardware issue. Some of the most likely issues include:

  • Water damage. You might have gotten your phone wet and it has caused some components to fail.
  • Drop damage. If you’ve dropped the phone, it might have damaged the screen (most likely) or internal components (less likely), preventing it from working.
  • Component failure. As reliable as iPhones are, it’s always possible that one can fail due to a manufacturing defect. It’s rare, but it can happen.

To see if your phone has any life in it at all, try this:

  1. Connect your ailing iPhone to a USB-C cable and plug it into a computer.
  2. If you are using a windows computer, open iTunes. If you are using a Mac, open Finder.
  3. Check to see if iTunes or Finder recognizes your iPhone. You should see the icon for your iPhone appear in the iTunes or Finder window. If so, you’re in luck — your iPhone is actually powered on, and you can probably back it up.
  4. If you see the iPhone icon appear, click it and then click Back Up Now to try to ensure you have a good backup of your phone’s apps and data. You can later use this backup to restore your phone after it’s serviced or replaced.

5. Contact Apple support

If your iPhone still won’t turn on, you might need service. Contact Apple support to have your phone serviced or replaced.
