A variety of issues can cause your iPhone to become unresponsive or even not turn on. The good news is that you can fix most of these issues without having to take your phone to a repair shop. We’ll discuss the steps you can take below.
1. Let the iPhone cool down
When an iPhone gets too hot, it's designed to shut down and stop everything except emergency calling. There may be cases where the iPhone won't turn on at all and becomes completely unresponsive, with nothing on the screen. But sometimes, you may see a message that says "iPhone needs to cool down before you can use it."
To turn your iPhone back on, cool it down by placing it in a cool, dry place away from direct sunlight. Never try to cool your iPhone immediately by placing it in the freezer or next to an air conditioner. This can cause condensation and damage your device.
2. Charge iPhone
This may seem like the most obvious option when your iPhone won’t turn on. But to be safe, it’s best to rule out overheating as the cause before attempting to charge your iPhone. In this case, the simple reason your iPhone won’t turn on is that the battery is completely drained.
You may see the Insert Lightning Cable/USB-C icon appear when you try to turn it on. When you plug it in, the icon will disappear. The red battery icon remains while the iPhone is charging.
In some cases, if you haven’t used your iPhone for a long time, the icon may not even appear because the battery has completely drained during storage. Fortunately, this doesn’t necessarily mean that your iPhone is damaged or unusable.
Simply connect your iPhone to the charger and wait 15 to 30 minutes. If your device is still working, you will eventually see a charging indicator appear on the screen. Once your device is charging and has enough power, your iPhone will turn on automatically.
3. Check the Lightning or USB-C cable
When the cable is faulty, the iPhone won't charge. So if the Insert Lightning Cable/USB-C icon remains even after you plug it in and try to charge it, the iPhone won't turn on no matter how long you wait.
You can try different cables of the same type if you are having charging issues. Don't overlook the charger as they tend to get damaged too.
Make sure you use a safe, high-quality charging cable that's not frayed or damaged, and check that you have the correct cable and charger for your iPhone.
4. Force restart iPhone
If your iPhone won't turn on because it's stuck in a boot loop, displaying the Apple logo, or completing an iOS upgrade, one solution is to force restart your iPhone. The exact process varies depending on your iPhone model, so follow our guide on how to force restart your iPhone . In the rare case that you can't turn off your iPhone, a force restart can help.
5. Restore iPhone using computer
If none of the above solutions work, it’s time to try the Apple Devices app (on Windows) or Finder (on macOS). Plug your iPhone into your PC or Mac. If it recognizes the USB connection, now would be a good time to back up your iPhone.
Once the backup is complete, see if there is an update available for your iPhone by tapping Check for Update . If you are running the latest version of iOS, tap Restore iPhone to reinstall it. You will be able to restore the backup you made after the process is complete.
If your computer doesn't recognize the connection, it's time to put your iPhone into Recovery mode . Once you've done that, Finder or Apple Devices will recognize your iPhone and let you tap Restore iPhone to reinstall iOS, but you'll lose anything you haven't backed up.
6. Replace iPhone battery
Sometimes, it can take hours for an iPhone to turn back on. It depends on how long the iPhone battery has been drained. However, if the iPhone is an older device that has been sitting in a drawer for a long time, the problem could be that the battery is completely dead.
This can happen if the above solutions do not solve your iPhone not turning on problem. Therefore, it is recommended to replace the iPhone battery, which is a relatively easy fix in the overall iPhone problems.
You can pay Apple to do it, but if you have AppleCare+, you may be able to get it replaced for free. You can also get the battery replaced for less at a reputable service center.
However, keep in mind that it may not just be a battery issue. If the cause is something more serious, your efforts will likely be for naught.
7. iPhone Repair
If your iPhone won't turn on and has signs like a flickering screen or a cracked screen, it may be damaged. Causes of damage include dropping it, getting it wet, or leaving it exposed to extreme temperatures for a long period of time.
The extent of the damage will determine the cost of repairing your iPhone. Unfortunately, an iPhone that won't turn on is often due to something other than a broken screen. For example, water and static electricity can cause serious damage that often requires a replacement. If this is the case, take your iPhone to Apple or a third-party service provider for repair options.
Good repair centers will usually tell you if repairs are possible if your iPhone won't turn on. They can also give you an estimate of the cost before doing the work.
Before you spend too much money on repairs, consider the cost of a replacement device plus the money you could make from selling your old iPhone. If you can't sell it because it's damaged, you can donate it to a nonprofit to recycle for fundraising purposes!
Many different issues can cause your iPhone to become unresponsive or even not turn on. The good news is that you can fix most of these problems without having to take your phone to a repair center.
