Why won't my iPhone turn on?
We'll start by examining common causes of iPhone not turning on because understanding the root issue is crucial to implementing the appropriate solution.
The reasons for this are numerous, but the following four are the most common:
If you are confused by a black screen on your iPhone, the cause could be a dead battery.
Power issues are common when your device shuts down suddenly despite having a longer battery, or when it tends to heat up quickly.
As Apple batteries age, their efficiency decreases and their capacity to hold a charge decreases.
As a result, their performance drops, especially when operating with low battery levels, often resulting in unexpected shutdowns.
Despite the proliferation of waterproof designs in modern devices, it's important to note that even a small amount of liquid can damage certain internal components and render your iPhone unusable.
If you suspect your iOS device has experienced liquid damage and isn't responding, we recommend checking out our comprehensive water damage guide.
If you've recently dropped your iPhone, it may stop working even if it doesn't show any visible signs of damage.
To find out if this is the case, shine a lamp on the screen to check for damage and try calling your phone to see if it rings or vibrates.
Even if your screen has been cracked for a long time, constant use has further damaged the device, making it appear as if it is turned off.
Sometimes software issues can cause your iPhone not to turn on.
Problems due to certain apps or iOS updates can contribute to this situation.
Also, if your iPhone crashes during an OS update, it can cause it to become unresponsive.
What to do to fix iPhone won't turn on issue?
1.Charge your iPhone
The problem may not be a software bug, but a dead battery.
The first step is to charge your phone. Give it an hour or two to charge the battery. If you see the "plug in lightning cable" icon, don't worry and let it charge for a while.
To rule out excessive heat as a cause, connect your phone directly to a power adapter and not to a computer's USB port. If the Lightning or USB connector is defective, charging and switching on can be prevented.
If charging with an AC adapter doesn't work, we recommend contacting Apple Support or visiting an Apple Retail Store for more help.
However, when you plug in your charger, you may get an error message like "Liquid detected in Lightning connector' or 'Unable to charge'. You can solve this problem with a simple tap.
2.Check your cable and charger
It's important to check your cable, charger, and Lightning connector for signs of damage.
It is also recommended to clean the port with a soft tool and use a different cable or charger if necessary to avoid fake chargers.
If you still see the Connect Lightning Cable icon, your iPhone won't turn on. In this case, try using other cables and chargers.
It is also important to dispose of any damaged cables responsibly, e.g. by recycling them on site.
3.Force restart iPhone
To determine if your iPhone is experiencing a software bug that is preventing it from waking, try forcing the device to restart.
Remember that your iPhone is normally on unless intentionally turned off, even if the screen is dark.
If the device restarts, the problem is probably due to corrupted data or an error in an app you are using.
The steps to force restart your iPhone may vary depending on the model.
