The iPhone is one of the most stable smartphones on the market and usually has the least number of failures, but it is true that it is not free of failures (it is impossible with any product) and sometimes it can give you a scare like not turning on or the screen going completely black . In other words, it will be completely dead.
Usually these failures are caused by the device software and more specifically by some process that has been left hanging, which does not allow iOS, your operating system, to respond normally.
Solutions to iPhone power and black screen problems
If you are in this situation and your iPhone doesn’t respond , doesn’t turn on or the screen is completely black, in the following lines I want to give you several options to recover the normal functioning of the equipment.
1.- Force the reset of the device
If you find yourself in some of these situations the quickest, and usually most effective, is to force a reboot or hard reset of the iPhone. By doing this you will get all software processes to close and when restarted they will start again, so in case of a single failure it will be fixed.
Depending on your iPhone model you will have to do the hard reset one way or another:
iPhone 11, Xs, Xr, X and 8
On the latest iPhone models you should do the following:
- Press the volume up and volume down button once.
- Press and hold the iPhone On/Off Button until the Apple logo appears on your smartphone screen.
Once this is done, you can release all the buttons and simply wait for the iOS to fully boot up before using the device again normally.
iPhone 7 and 7 Plus
The iPhone 7 was the first Apple smartphone without a home button with a mechanical movement and because of this the process to make a hardreset changed compared to previous generations. If you have one of these devices you should do the following:
- Press the volume down and on/off buttons.
- Press and hold both buttons until the Apple logo appears on the screen (this will take a few seconds).
Once this is done, you will have to wait until iOS boots up completely and you will be able to use the device again just like the rest of the devices in the firm.
iPhone 6s, 6, 5s, 5, SE and earlier generations
As I was saying, the iPhone 7 was the first Apple smartphone where the process to force the reboot changed, so if you have any previous generation the process is the next one:
- Press the device’s on/off and home buttons.
- Press and hold both buttons until the Apple logo appears on the screen.
As with recent generations, this process should take no more than a few seconds (5-10 normally), and after that time you will only have to wait for iOS to start up again to use the device normally.
If everything went well and the problem that prevented the iPhone from turning on was a one-time software failure, everything should be back to normal and you will be able to continue using the device. If the screen is still black or unresponsive, read on to see other possible solutions .
2.- Charging the iPhone battery
When the battery of an iPhone runs out completely the screen stays completely black and does not respond even if you press one of the physical buttons of the mobile. It’s true that for this to happen the battery has to be almost completely drained and you may think that it has not had time to do so, but just in case it never hurts to check it.
Put your iPhone on charge with the original charger or through a wireless charger if you have one of the latest generations, and wait a few minutes to see if the device reacts.
When the charge is fully exhausted it may take up to 15-20 minutes for the iPhone to turn on after charging, so be patient at this point. I would wait at least 30 minutes before trying the next solution if it doesn’t react, so you can be 100% sure that it’s not a power failure problem.
3.- Restore the iPhone to factory status
If all of the above has failed, the problem may be a little more serious and it may not simply be a one-time failure.
In this case before thinking about a hardware problem it is highly recommended to do a restore of the device to factory status. With this all the software will be back to the way it was when the device was new and you can verify that the problem is with the operating system or some app and not with the hardware.
Before explaining the restoration process it is important to mention that by doing so you will lose all data , settings and apps installed on the device. One more reason to remember the importance of backing up your iPhone on a regular basis; after all, you never know when it might fail or when you might simply lose it.
To restore your iOS device to factory default, follow these steps:
- Put your iPhone in DFU mode by following the steps outlined in the article in the previous link according to your smartphone model.
- Connect iPhone to a Mac or Windows PC with the USB cable and run iTunes (it’s strongly recommended that you have the latest available version of the software installed). If you’re using Catalina Macs or higher, you’ll need to use Finder instead of iTunes, since Apple has decided to remove it in this version.
- iTunes or Finder will detect the device in DFU mode and guide you through a factory reset. Simply follow the on-screen instructions until the process is complete.
After the restoration and if everything has gone well, the device will return to normal operation. No more iPhone not turning on or the screen going black, and you can use it normally in your daily life.
What if the iPhone still doesn’t turn on?
As I was saying, in most cases one of these three solutions is sufficient to repair errors caused by software. If after trying to apply these solutions the problem persists, it is likely that there will be a more significant hardware failure.
In this case my recommendation is that you go to an authorized service center so that they can check your computer and locate exactly where the problem is that keeps the screen black or that the iPhone does not turn on to solve it.
If you get to this point, there is most likely some damage to the motherboard, the device’s LCD or OLED panel, or even some of the cables connecting the panel to the motherboard. The technician may check the device and provide you with a repair estimate depending on the problem he detects. In addition, in some cases Apple may also offer to give you a new device instead of fixing the problem.
