The iPhone is one of the most stable smartphones in the market and that fewer failures usually have, but it is true that it is not free of failure (it is impossible) and in some cases can give you the odd scare as it does not turn on or the screen is left in black completely.
Generally, these failures are caused by the software of the device and more specifically by some process that has been left hanging, which does not allow iOS to respond normally.
Your iPhone does not turn on? Do you keep the black screen? Here are some solutions
If you are in this situation and your iPhone does not respond, does not turn on or the screen has been completely blacked out,[appbox xda ] in the following lines I want to give you several options to recover the normal operation of the computer.
1.- Force the restart of the device
If you see yourself in some of these situations as fast, and generally effective, it usually forces a reset or hard reset of the iPhone.
By doing this you will get all the software processes closed and on restarting they will start again, so in case of a specific failure will be solved.
Depending on your iPhone model you should do the hard reset in one way or another:
iPhone Xs, Xr, X and 8
In the most recent models of the iPhone you should do the following:
- Click on the volume up button and another on the volume down button.
- Press and hold the iPhone on/off button until the Apple logo appears on the smartphone screen.
Once this is done, you will be able to release all the buttons and you will simply have to wait for iOS to fully boot to reuse the device normally.
iPhone 7 and 7 Plus
The iPhone 7 was the first Apple smartphone without home button with mechanical movement and because of this the process to make a hard reset changed in front of previous generations. If you have one of these devices you should do the following:
- Press the volume down and on / off buttons.
- Keep both buttons pressed until the Apple logo appears on the screen (it will take a few seconds).
Once this is done, you will have to wait for iOS to boot completely and you will be able to use the device again.
iPhone 6s, 6, 5s, 5, SE and previous generations
As I said, the iPhone 7 was the first Apple smartphone in which the process to force the restart changed, so if you have any previous generation the process is as follows:
- Press the on / off and home buttons of the device.
- Keep both buttons pressed until the Apple logo appears on the screen.
As with the most recent generations, this process should not take more than a few seconds (between 5 and 10 normally) and after that time you will only have to wait for iOS to start to use the device again normally.
If everything went well and the problem that prevented the iPhone from turning on was a specific software failure, everything should have returned to normal and you could continue using the device. If the screen is still black or does not respond, read on to see other possible solutions.
2.- Charge the iPhone battery
When the battery of an iPhone runs out completely the screen is completely black and does not respond even if you press any button. It is true that for this to happen the battery has to empty a lot and you may think that it could not give you time, but just in case it never hurts to check it.
Put the iPhone to 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 has run out completely it is possible that the iPhone takes a long time to turn on until 15 or 20 minutes after loading it, so be patient at this point. I would wait at least 30 minutes before trying the next solution if it does not react.
3.- Restore the iPhone to factory state
If all the above has failed, it is possible that the problem is a little more serious and perhaps it is not simply a specific failure.
In this case, before thinking about a hardware problem it is highly recommended to restore the device to the factory state. With this, all the software will be like when the device was new and so you can verify that the problem is the operating system or some app and not hardware.
Before explaining the restoration process it is important to mention that in doing so you will lose all the data, configurations and apps installed on the device. One more reason to remember the importance of backing up the iPhone on a regular basis; After all, you never know when it can fail or when, simply, you can lose it.
To restore the iOS device to the factory state you must follow these steps:
- Put the iPhone in DFU mode following the steps indicated in this article according to your smartphone model.
- Connect the iPhone to a Mac or Windows PC with the USB cable and run iTunes (it is highly recommended that you have the latest available version of the software installed).
- iTunes will detect the device in DFU mode and will guide you to perform the restoration to the factory state. Simply follow the instructions on the screen.
After the restoration and if everything went well, the device will work normally again. It is over that the iPhone does not turn on or the screen is black and you can use it normally in your day today.
What if the iPhone still does not turn on?
As I said, in most cases any of these three solutions are enough to repair errors caused by software. In the event that after trying to apply these three solutions the problem persists, it is likely that there is a more important hardware failure.
In this case, my recommendation is that you go to an authorized technical service so they can check the equipment and locate where exactly the problem is that keeps the screen black or that the iPhone does not turn on to give a solution.
