Experiencing a black screen when you try to power on your phone can be incredibly frustrating. It can happen after charging, after a drop, or seemingly out of nowhere. Before you panic, know that there are several reasons why your phone might not be turning on, and many of them can be resolved with simple troubleshooting steps. This guide will walk you through a series of actions you can take to diagnose and potentially fix the issue, helping you understand “why won’t my phone turn on” and get it working again.
Preliminary Checks: Ensuring Basic Functionality
Before diving into more complex solutions, it’s crucial to rule out the simplest causes. These initial checks will help you confirm basic functionalities and identify if the problem is easily solvable.
Check the Power Button
The most fundamental step is to ensure you are properly attempting to power on your device. Sometimes, a simple mispress or a slightly unresponsive button can be the culprit.
- Press and Hold: Firmly press and hold the power button for a more extended period than you normally would – around 20-30 seconds. This prolonged press can sometimes bypass minor software glitches that are preventing a normal startup.
- Listen for Feedback: While holding the power button, listen closely for any subtle sounds or vibrations from your phone. A faint vibration or a very quiet startup sound could indicate that your phone is indeed trying to turn on, even if the screen remains black.
Verify Your Charger and Cable
Charging issues are a common reason why a phone might fail to power on. A faulty charger or cable can prevent your phone from receiving the necessary power to operate.
- Inspect for Damage: Carefully examine your charging cable and adapter for any visible signs of damage. Look for frayed wires, bent connectors, or cracks in the adapter casing. Damage to these components can disrupt the flow of electricity.
- Try a Different Charger and Cable: If possible, test your phone with a different charger and cable that you know are working correctly. This will help you isolate whether the problem lies with your original charging equipment.
- Ensure Proper Connection: Make sure the charging cable is securely plugged into both your phone and the power adapter, and that the adapter is firmly plugged into the power outlet. A loose connection can interrupt charging.
Test a Different Power Outlet
Sometimes, the issue isn’t with your phone or charger, but with the power outlet itself. A malfunctioning outlet won’t provide power to your charger, preventing your phone from charging.
- Try Multiple Outlets: Plug your charger into several different power outlets in your home or office. This will help you rule out a problem with a specific outlet.
- Test the Outlet with Another Device: To confirm if an outlet is working, plug in another electronic device, such as a lamp or another phone charger. If the other device also doesn’t receive power, then the outlet may be faulty.
Basic Troubleshooting Steps: Addressing Common Causes
Once you’ve ruled out basic power and connection issues, you can move on to more in-depth troubleshooting steps. These actions target common software and hardware problems that can prevent your phone from turning on.
Perform a Force Restart
A force restart is a powerful first step in troubleshooting “why won’t my phone turn on”. It’s similar to rebooting your computer and can often resolve software glitches that are causing your phone to be unresponsive. The method for force restarting varies slightly depending on your phone model:
-
For iPhones:
- iPhone 8 and later: Press and quickly release the Volume Up button, then press and quickly release the Volume Down button, then press and hold the Side button until you see the Apple logo.
- iPhone 7 and iPhone 7 Plus: Press and hold both the Side button and the Volume Down button until you see the Apple logo.
- iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Home button and the Top (or Side) button until you see the Apple logo.
-
For Android Phones: The most common method is to press and hold the Power button and the Volume Down button simultaneously for about 10-15 seconds. However, the specific button combination can vary by manufacturer. Consult your phone’s manual or the manufacturer’s website for the correct method for your specific model.

Check for Physical Damage
Physical damage is a significant concern when your phone won’t turn on. Drops, impacts, or exposure to liquids can cause internal damage that prevents the phone from powering up.
- Visual Inspection: Thoroughly inspect your phone for any signs of physical damage. Look for cracks on the screen or body, dents, or any other visible deformities. Pay close attention to areas around ports and buttons.
- Liquid Damage Indicators: Many phones have liquid damage indicators (usually small stickers that change color when exposed to moisture). Check your phone’s manual to find the location of these indicators and inspect them for signs of liquid exposure.
- Recent Incidents: Think back to any recent incidents that might have caused physical damage, such as dropping your phone, spilling liquid on it, or exposing it to extreme temperatures. These incidents could be directly related to the power-on issue.
Carefully Inspect the Display
Sometimes, the issue isn’t that your phone won’t turn on, but rather that the display is not functioning correctly. The screen might be black, but the phone itself could be operating in the background.
- Dark Room Test: Take your phone into a completely dark room and try turning it on. Look very closely at the screen for any faint backlight or very dim images. This can be an indication that the display is receiving power but is extremely dim or malfunctioning.
- Shine a Flashlight: In a dimly lit room, shine a flashlight at an angle onto your phone’s screen while attempting to turn it on. Look for faint outlines of icons, text, or other screen elements. If you can see faint images, it suggests the display is the primary problem, not the phone’s power.
- Notification Sounds or Vibrations: Try calling your phone from another device or sending it a message. Listen for notification sounds or feel for vibrations. If your phone is responding to notifications, it’s likely powered on, and the problem is related to the display.
Rule Out Overheating
Overheating can sometimes prevent a phone from turning on, especially if it has been exposed to direct sunlight, a hot car, or prolonged charging. Phones have thermal safeguards that can shut them down to prevent damage from excessive heat.
- Check for Warmth: Feel your phone to see if it feels unusually warm or hot. Overheating can be caused by excessive use, charging in a hot environment, or even a malfunctioning battery.
- Let it Cool Down: If your phone feels warm, allow it to cool down to room temperature before attempting to power it on again. Place it in a cool, shaded area away from direct sunlight or heat sources.
- Avoid Extreme Temperatures: In the future, avoid leaving your phone in direct sunlight or hot environments, especially during charging. This can help prevent overheating issues.
Address Potential Battery Drain
If your phone’s battery has been completely drained, it might not turn on immediately even when plugged into a charger. A deeply discharged battery needs a certain amount of charge before the phone can power on.
- Charge for an Extended Period: Connect your phone to a working charger and let it charge for at least 15-30 minutes, or even longer. A completely depleted battery may require a longer charging period before showing any signs of life.
- Observe for Charging Indicators: While charging, look for any charging indicators on the screen (even if it’s still black) or a charging light on your phone. These indicators can confirm that your phone is receiving power and charging.
- Try Different Charging Setups: If your phone still doesn’t show signs of charging, try different combinations of chargers, cables, and outlets to rule out any issues with your charging setup.
Advanced Troubleshooting: Exploring Deeper Issues
If the basic troubleshooting steps haven’t resolved the “why won’t my phone turn on” issue, it’s time to consider more advanced solutions. These steps address potential software or hardware problems that require more technical intervention.
