Part 1. Common Cases of iPhone Won't Turn On

Before diving into specific fixes, it's important to understand the various scenarios in which your iPhone might fail to turn on. Identifying the exact situation can help you narrow down the potential causes and determine the appropriate troubleshooting steps. In this section, we'll explore some common cases where an iPhone won't power up.

Case 1. iPhone Won't Turn On or Charge

When your iPhone refuses to turn on and doesn't charge, it can leave you feeling stuck. Despite plugging it into a power source, the device remains unresponsive, not showing any signs of charging or powering up. This situation is common, and it may occur unexpectedly. It usually occur when the charging accessories are broken.

Case 2. iPhone Died and Won't Turn On

If your iPhone suddenly dies and won't turn on, even after attempting to charge it, it's time to fix it. The device appears completely unresponsive often after external damage or some virus attack. If this is the case, no matter how much time you wait, the iPhone refuses to show any sign of life unless you take some measures.

Case 3. iPhone Won't Turn On after Update

Many users report their iPhone won't turn on after an update, either an iOS upgrade or a minor system patch. While updates are typically designed to improve the phone's performance, they can sometimes cause bugs that prevent the device from turning on. This issue might be due to incomplete installation, software corruption, or even incompatibility with apps.

Case 4. iPhone Won't Turn On after Dying

It's not uncommon for iPhones to refuse to turn on immediately after the battery has completely died. This can be especially true if the battery has been drained to 0% and hasn't had a chance to recharge. In some instances, the device may need extra time to boot up after being connected to a charger. This case can also sometimes indicate a battery health issue or software malfunction.

Case 5. New or Old iPhone Won't Turn On

Whether your iPhone is brand new or an older model, a failure to turn on can happen sometimes. A new iPhone may experience issues due to manufacturing defects, faulty parts, or incorrect initial setups. For older devices, wear and tear can lead to power failures, with issues like battery degradation or internal component failures being the most common culprits. In both cases, timely fixes are essential.

Part 2. Why Won't My iPhone Turn On?

If your iPhone won't turn on, it could be due to an external or internal reason. Common external causes include a faulty battery or damaged charging cables. Besides, physical damage from drops or water exposure can also prevent the phone from powering up, as can overheating. Internally, software or system issues might be to blame. In the following section, we'll present several fixes to help get your iPhone up and running again.

Part 3. What to Do If iPhone Won't Turn On [External]

When your iPhone refuses to turn on, the first step is to check for any external issues that may be preventing it from powering up. These issues are often easier to resolve and could be the result of something as simple as a faulty charger or a dirty charging port. Here are some external fixes you can try.

Method 1. Wait and Reboot iPhone

Sometimes, the issue could be as simple as a temporary software glitch that's preventing the iPhone from starting up. In such cases, waiting for a few minutes and then attempting a reboot can help resolve the issue. Try to restart the device using the necessary button combinations and see if it powers up.

Method 2. Charge the iPhone

If your iPhone won't turn on, the first thing you should check is whether it's running out of power. Plug it into a charger and wait for a few minutes. If the device doesn't show the Apple sign after charging or your iPhone won't start due to charging for a long time, you can switch to the next method.

Method 3. Alter the Charger

A malfunctioning charger or cable may be the main reason behind your iPhone's failure to charge. Swap out the charging cable and adapter to see if this resolves the issue. If you have a spare charger or are using an uncertified third-party charger, try using an Apple-certified one to ensure compatibility.

Method 4. Tidy Up Charging Port

Over time, dust, lint, and other debris can accumulate inside the charging port, preventing a proper connection. Use a soft brush, compressed air, or a toothpick to gently clean out the charging port and remove any blockages. After cleaning, you can try plugging in the charger one more time.

Method 5. Check External Damage

Check the exterior of your iPhone for any signs of physical damage. A cracked screen, bent body, or water exposure can cause the phone to become unresponsive. If you notice any obvious external issues, it may be time to have your device do an internal fix listed in the next part.
