What can possibly cause your new iPhone 7 Plus to not power on or turns on but stuck on black screen?

Given the fact that what you have is a new device, the issue shouldn’t be on the hardware unless the problem started after an incident of dropping or liquid exposure. But if you are certain that none of these things happened and you’ve got your new iPhone acting up this way, then it must be triggered by something on the software components.

The first thing you need to look into is the battery. There is a higher chance that your iPhone has just ran out of power completely. Some apps can make your iPhone’s battery drain faster than usual and eventually become empty even if you were not using your device that often. When your iPhone battery is completely drained, it could take longer than usual to recharge, thereby making you think that your iPhone is dead.

The same thing can also happen when using a bad battery on your iPhone. But this should not be the case on your end because what you have is a new device, which denotes that all its components are likewise new and functional. Yet, it is still worth checking.

Other iPhone owners have also experienced similar issue after installing software updates including major iOS firmware updates on their respective devices. Apparently in this case, certain software bugs must have messed up the phone’s power system and thereby making it dead, won’t turn on, or turns on but couldn’t get past the black screen. Problems like this inevitable when it comes to major software revamps. Although Apple has made it sure that their every iOS or firmware update release must be completely error-free, the outcome can vary during the actual implementation. This is because not all users have set their iPhones in a similar way that Apple does while testing and evaluating their new software. That being said, something in the phone’s current system settings have caused conflict with the new platform and thereby prevents your iPhone from power on or complete the start-up process. For example, some users may have configured their devices in such a way that does not blend with the new iOS program structure and therefore resulted to this problem.

Aside from not turning on, an iPhone can also succumb into other issues during start-up including stuck on the Apple logo, red screen or blue screen of death following the implementation of a major software update or firmware patches.

Memory problems can also inflict similar symptoms to occur on an iPhone along with other performance issues. While this should not be happening on your end especially with the iPhone 7 Plus’ immense storage capacity, there are some factors that can cause memory issues to occur at random times. For example, a third-party app has gone rogue, messed up the phone’s memory system, and finally causes your iPhone to develop unusual symptoms including won’t turn on or won’t start up. With memory issues, your iPhone may not be able to perform as it should as your device could no longer carry out additional processes.

In worst cases, your new iPhone may not power on or stuck on black screen because of hardware problems. It can usually happen when your iPhone was dropped or got soaked into any forms of liquid. Symptoms of physical or liquid damage may not transpire immediately after the actual incident of dropping or getting wet. But when the time comes for these symptoms to manifest, your only option would be to seek for professional aid or if possible, avail for warranties.

What to do when your iPhone 7 Plus does not power on or turns on but stuck on black screen?

Fortunately in the case where the software is to blame, there are a few efficient workarounds you can try on that can possibly fix the problem and get your iPhone back up and running and without having any more trouble powering up. Considering that the problem you have is not due to any hardware damage, you may try any of the following workarounds before contacting an Apple technician.

Step 1. Connect your iPhone 7 Plus to a power source

To eliminate the possibility that your iPhone has just completely ran out of power, you can try to connect it to a power source and then let it charge for at least an hour. By the time your iPhone gets enough charge, it should turn back on. But if after an hour you noticed that your iPhone did not charge, it denotes a need for you to deal with the problem on charging first. There is a higher chance that main issue can likewise be resolved once you have settled any existing problems with charging. You may try to use other compatible chargers with your iPhone to isolate if the problem is on a faulty charger or charging equipment.

Step 2. Force your iPhone 7 Plus to restart

Should the problem is caused by random software glitches or program malfunctions, performing a force restart might be very helpful. Forcing your iPhone to restart will not erase any contents thus deemed a safe process for you to try on.

  • To force your iPhone 7 Plus to restart, press and hold the Sleep/Wake button and the Volume Down button simultaneously for at least 10 seconds until the Apple logo appears.

A force restart is usually done when a device is unresponsive and performing the usual reboot is not an option. It is a widely used workaround to deal with various issues caused by software malfunctions in mobile devices including iPhones and iPads.

Step 3. Check your iPhone 7 Plus memory status with iTunes

Although it may sound bizarre, your new iPhone can still succumb to memory glitches due to certain factors like software bugs or faulty applications. To make sure that every program installed on your device is working normally, you can connect your iPhone to a computer and use iTunes to check its memory status. You can use either Windows or Mac computer to continue with these steps:

  • Connect your iPhone to the computer using the supplied USB cable/connector.
  • Once connected, open iTunes on the computer. As much as possible, be sure to use the latest iTunes version to avoid system conflicts.
  • Select your iPhone 7 Plus from the list of available devices in iTunes. Once selected, you will see a bar that indicates how much storage each of your device content utilizes divided by the content type.
  • Move your mouse over a content type like Other or Apps, to view more information and take appropriate actions.

If you were able to get your iPhone to power on after charging, then you can just head over to Settings-> General-> Usabe-> Manage Storage and then carefully review the details on how your iPhone’s overall internal storage space is allocated. If necessary, you can clear the cache or remove temporary files for an app, or uninstall non-essential apps or complex files from your device. To view additional information on each application’s memory allocation, simply tap on a desired app from the list. If you see something suspicious like certain app is consuming too much of your phone’s memory space, then you must do something to fix it.

Step 4. Use Recovery Mode to manage your iPhone 7 Plus iOS

Another possible solution you can try on your end is putting your iPhone into Recovery Mode and then update or restore iOS through iTunes. Again, you will need a computer with the latest version of iTunes installed, in order to proceed with this method. Follow these steps when everything is ready:

  • Connect your iPhone to your computer, and then open iTunes on the computer.
  • While your iPhone is connected, perform a force restart. Again to force restart, just press and hold the Sleep/Wake button and Volume Down button simultaneously. But this time, do not release both the buttons when you see the Apple logo.
  • Keep pressing both buttons until you see the Recovery Mode screen. By then you can release both buttons simultaneously.
  • Once you’re iPhone is in Recovery Mode, you will be prompted with options to Restore or Update. If you wish to proceed with an iOS restore, tap Restore. Otherwise, tap to select Update to continue with iOS update via iTunes.

When you select Update, iTunes will try to re-install iOS without deleting your contents and then proceed with downloading of software for your iPhone. The download process could take a few minutes depending on the file size of the software to download.

If the download takes more than 15 minutes though, your iPhone will exit recovery mode and should that happens you will need to repeat the steps from the force restart down to the point when you get to the Recovery Mode screen.

You can also update your iPhone 7 Plus to the most recent iOS 10.3 version using iTunes.

Just check if that update is already available for your device and if so, you may go ahead and proceed with iOS update installation via iTunes.

Several enhancements as well as fixes to certain bugs are embedded with this iOS update. Among the key features the iOS 10.3 brings include the new Find My AirPods, a Find My iPhone tool that is designed to help users locate lost AirPods. The iOS 10.3 also contains fixes for the 30% battery bug found in iOS 10.2 and 10.2.1.

If you wish to update your iPhone 7 Plus to iOS 10.3 via iTunes, please refer to the above steps on putting your iPhone into recovery mode until you reach the Update or Restore prompt.

Step 5. Restore iPhone 7 Plus firmware via DFU Mode

If putting your iPhone into recovery mode did not give you any positive results, then your next option is to try to put your device in DFU or Device Firmware Update mode instead. DFU mode is another iOS system state that lets your iPhone device communicate with iTunes without having to load its operating system or launch the iOS boot loader. You can use DFU mode to edit the iOS firmware, whether it’s for downgrade or use of custom firmware for the iPhone. Follow these steps if you want to proceed with DFU Mode firmware restore:

  • Connect your iPhone to a computer with the latest version of iTunes installed.
  • Open iTunes on the computer.
  • With your device completely powered off, press and hold the Sleep/Wake button for 3 seconds.
  • While holding the Sleep/Wake button, press and hold the Volume Down button and keep holding both buttons for 10 more seconds.
  • If you see the Apple logo, it means that you have held the buttons for too long and in this case you will need to start all over. Otherwise, continue to the next step.
  • Release the Sleep/Wake button but keep holding the Volume Down button for 5 more seconds. The Plug into iTunes screen will appear if you have held the button for too long. This means you need to start all over.

An indication that your iPhone is in DFU mode is when the iPhone screen remains black after releasing the Volume Down button at the specified period of time. At this point, you should see an iTunes prompt, saying that iTunes has detected your iPhone and will then attempt to restore iOS. Once iTunes is finished restoring iOS, try to power on your device.

Step 6. Contact your carrier or Apple Support

If none of these recommended workarounds is able to help or your iPhone 7 Plus still does not power on or stuck on black screen, then you should contact your carrier to escalate the problem and ask for further support. Otherwise, you can go ahead and give Apple Support a call for other recommendations. You can also try to avail for iPhone 7 Plus service or unit replacement warranty, especially if there’s nothing more can be done to get your iPhone back up again.
