No matter what your iPhone can do, at the end of the day, there is going to be a need for it to charge. This is a simple fact and one that many iPhone owners are more than happy to oblige to, but what do you do if your iPhone keeps flashing on and off while charging.

If your iPhone keeps turning, blinking, or flashing on and off while charging, it could be that the operating system needs to be updated, that the charger is damaged, that an app on the phone is causing the issue and needs to be deleted and reinstalled, or that a forced restart is needed.

Whether you are in the middle of a text, at the end of an important phone call, are going through specific notes, or are scrolling through social media, no one wants their iPhone to turn on and off without warning. Not only is this inconvenient for the user, but it makes the iPhone owner worry that something is seriously off with their device. If you notice, when using your iPhone that it suddenly turns on and on without your prompting, take a look below to find a solution.

If your iPhone keeps turning on and off, it could be that you need to update the operating system within your phone. To check to see if an update is available, go to ‘Settings’ > ‘General’ > ‘Software Update’ and look to see if any updates are ready to be installed on your iPhone.

If there are updates available, you will then need to connect your iPhone to a charger and a wifi network, then click to install the new software. During this installation process, be sure to leave your iPhone on the installation page so that the installation is not paused and it can proceed as quickly and efficiently as possible. Once the new software has been installed, you will be notified of its completion and taken through any major changes that may have been made.

If there are no available updates or if the update did not resolve your issue of your phone turning on and off on its own, it could be that the battery life of your phone has reached its end. To check the health of your iPhones battery, you will go to ‘Settings’ > ‘Battery’ > ‘Battery Health’ and check to see if the maximum capacity of your battery is listed as ‘Low.’ If it is, this could be the reason that your phone is turning off and on without warning, and should be replaced.

iPhone Keeps Blinking/Flashing On/Off

When using your iPhone, you may not be having problems with the phone turning completely on and off on its own, but you may notice that the screen blinks or flashes off and on at random moments. This may not be as inconvenient as the phone completely shutting down, but when it comes to trying to maintain focus and keep on task when you are on your iPhone, it can be incredibly interruptive. If your iPhone is blinking or flashing on and off, continue reading.

If your iPhone keeps blinking or flashing on and off, check to pinpoint when these patterns happen the most. If it is when you are using a particular app, it is likely a problem with the application, rather than the phone itself which can be resolved by deleting and reinstalling the app.

The most simple fix to an app causing your iPhone to blink and flash on and off is to close the app and reopen it. Be sure that you completely shut down the particular application, don’t just exit out of it, and then try once again to open it. Once you open the app, pay close attention to whether or not you notice the flickering on your screen anymore. If it is gone, then the issue has been resolved, but if it is still there, take a look below to find another troubleshooting method.

Once you have closed out of the app, but are still experiencing problems with your iPhone blinking and flashing on and off, it may be helpful to delete the application and reinstall it. To do this, press on the application that is causing the issues until a small ‘X’ appears in the corner of the app, which you will then press to delete. Once you have deleted the app, you can go back into the app store, find the app, and reinstall it once again.

iPhone Keeps Turning On and Off While Charging

Charging an iPhone

When charging your iPhone, you should be able to keep it on without it waffling between being powered on and powered off. During this time, you should also be able to use the phone as you normally would as long as you have enough charge for the phone to be powered on and sustain the programs on it during charging. However, if you are in the middle of charging your iPhone and notice that the phone keeps turning off and on, what can you do to resolve the issue?

If your iPhone keeps turning off and on while charging, it could be that a forced restart is in order. This restart allows the memory of your phone to refresh, which can help resolve any minor issues that may be causing your phone to turn off and on, however, this process varies for different iPhones.

If you have an iPhone 7 or 7 Plus, to complete a forced reset, you will hold down the ‘Sleep/Wake’ button as well as the ‘Volume Down’ button simultaneously until the screen turns black and then the launch screen appears. For an iPhone 6 or earlier you will simultaneously hold down the ‘Sleep/Wake’ button and the ‘Home’ button until the same screen appears as previously mentioned with the iPhone 7.

If you have completed a forced reset with your iPhone but still notice that it is turning on and off while charging, you may want to check the charging cable you are using or the outlet in which it is plugged into. If the cord has any type of damage such as exposed wires or major dents in the cord, this can cause power to inconsistently reach your iPhone which can sometimes cause it to turn off and on. Be sure to check that the outlet is also in working condition with another device.
