iPhone won't Turn On? Here's Everything You Need to Know
You press the power button. Nothing happens. You hold it longer. Still, your iPhone screen is completely black, and your stomach sinks. Whether your phone just died out of nowhere or took a tumble off the counter, a dead iPhone is one of the most stressful tech problems you can face.
But the good news is that it can be fixed. Most of the time, an iPhone that won't turn on can be fixed without buying a new phone. We will walk you through every possible reason your iPhone won't power on and exactly what to do about it, from easy DIY steps to knowing when it's time to bring it in for professional repair, and if you choose National City Phones, how we will help you in the meantime.
Why Won't My iPhone Turn On? The Most Common Causes
If your phone appears completely dead, it can be frustrating. Before trying random fixes, let's identify the cause and where to go. Just stop and, before jumping into fixes, understand what's actually going wrong. There are six main reasons an iPhone refuses to turn on:
How to Fix an iPhone That Won't Turn On
Work through these steps in order. Start with the simplest fixes first.
1. Charge Your iPhone (For at Least 30–60 Minutes)
This sounds obvious, but it's the fix that works most often. If your iPhone battery is deeply discharged, plugging it in briefly won't wake it up immediately. The battery needs time to accumulate enough charge to boot.
What to do:
- 1. Plug your iPhone into a wall charger (not a computer USB port). Wall outlets provide more power.
- 2. Use a known-good cable and charging brick.
- 3. Leave it alone for at least 30 minutes, ideally 60.
- 4. Don't try to turn it on repeatedly during this time.
- 5. After 30–60 minutes, look for the low-battery charging icon or try pressing the side button.
If you see a red battery icon: Your iPhone is charging, but too low to turn on. Keep charging for another 30 minutes before pressing anything.
Force Restart Your iPhone
A force restart clears the device's RAM, kills any frozen processes, and reboots the system, all without erasing your data. This is the #1 fix for software-related black screens and frozen iPhones.
For iPhone 8, X, XS, XR, 11, 12, 13, 14, 15, 16, 17 (Face ID models):
- 1. Quickly press and release the Volume Up button.
- 2. Quickly press and release the Volume Down button.
- 3. Press and hold the Side button until the Apple logo appears (can take 10–20 seconds).
For iPhone 7 and iPhone 7 Plus:
- 1. Press and hold Volume Down + Side button at the same time.
- 2. Hold until the Apple logo appears.
For iPhone 6s, SE (1st gen), and older:
- 1. Press and hold Home button + Top/Side button simultaneously
- 2. Hold until the Apple logo appears
Check Your Charging Equipment
If charging for an hour didn't help at all, the problem may not be the battery; it may be your charger.
- 1. Try a different cable (cables fray internally even when they look fine).
- 2. Try a different charging brick.
- 3. Try plugging into a different wall outlet
- 4. Inspect your iPhone's charging port for lint, dust, or debris. A toothpick or compressed air can clear blockages.
- 5. If you have wireless charging, try that as an alternative.
Try Recovery Mode
If your iPhone still does not turn on after you charge it and do a force restart, it may need Recovery Mode. This way, you can use iTunes or Finder on your computer to put the iOS on your iPhone.
What you need to do this: you need a Mac with Finder or a Windows PC with iTunes and the cable that came with your iPhone.
Steps:
- 1. Open Finder if you have a Mac, or iTunes if you have a Windows PC on your computer.
- 2. Use the cable to connect your iPhone to the computer.
- 3. Do the force restart on your iPhone, but keep holding the side or power button until you see the Recovery Mode screen it looks like a cable and a laptop.
- 4. On your computer, choose Update in Finder or iTunes. This will put the iOS back on your iPhone without erasing anything.
- 5. Wait for it to finish. This can take around fifteen to twenty minutes.
If the update does not work, you can choose Restore. This will erase everything on your iPhone. Only do this if you have a backup or if you have no other choice.
Inspect for Physical Damage
At this point, if none of the software steps worked, the problem is likely hardware-related. Examine your iPhone carefully:
-
1. Is the iPhone screen broken or cracked?
A broken screen can look like the iPhone is not working when it is on. You might still hear notifications or feel vibration. -
2. Did you drop the iPhone recently?
Even if you do not see any cracks, the inside parts can still get loose. -
3. Was it exposed to water?
We need to check the Liquid Contact Indicator, which is a small white or red dot inside the SIM card tray slot. If the dot is red or pink, then the iPhone has been damaged by water. -
4. Is the iPhone very hot or making some noise?
This could mean there is a problem with internal parts.
iPhone Black Screen But Still On: What It Means
One of the most confusing situations is when your iPhone looks like it's off but it's actually still on. You might notice some weird things happening.
- 1. You get notification sounds or vibrations when a message arrives.
- 2. Siri responds when you say "Hey Siri".
- 3. Your phone rings when you call it from another number.
- 4. The screen flickers or shows a faint image at an angle.
This means your iPhone is on. The screen isn't working. That's different from when your phone won't turn on at all.
Usually, the problem is one of these:
-
The backlight on your screen is broken.
This often happens when you drop your phone. The backlight chip on the logic board fails. -
Disconnected display cable
The cable that connects the screen to the logic board is loose. A hard drop can cause this to happen. -
Damaged LCD or OLED panel
The LCD or OLED panel might be cracked inside even if it looks fine outside. It might have just failed. -
Power isn't reaching the display components properly.
This could mean there is a problem with internal parts.- 1. In cases where you need either a screen replacement or a logic board-level repair. Both of these fixes require a technician.
iPhone Won't Turn On After a Drop:
What You Should Do
Dropping an iPhone is one of the leading causes of power failures. Here's what happens internally when your phone hits the ground hard:
- 1. Soldered components on the logic board can crack or separate.
- 2. Ribbon cables connecting the display, battery, or charging port can detach.
- 3. The battery connector can loosen.
- 4. The screen and its backlight components can fail.
- 5. In severe drops, the logic board itself can bend or fracture.
Immediate steps after dropping your iPhone:
- 1. Don't panic and don't keep pressing buttons.
- 2. Look for any sign of life. Does it vibrate? Do you hear sounds?
- 3. Try the force restart sequence.
- 4. Charge it for 30 minutes.
- 5. If still nothing, bring it in for a diagnostic.
A trained technician can open the device and inspect for loose connectors, damaged components, or logic board issues.
iPhone Power Issues: When Is It the Logic Board?
The logic board, which is also known as the motherboard, is the complicated part inside your iPhone. It is in charge of getting power to all the parts, processing information, running your apps and making sure all the hardware works together. When the logic board has problems, it can cause issues or make your iPhone completely dead. In Nationali City, we are known for the best iPhone motherboard repair. We have all the tools and techniques that definitely help us to restore phones effectively.
Signs Your Logic Board May Be Failing
- 1. Your iPhone will not turn on even when you charge it, restart it and try to use recovery mode.
- 2. Shows the Apple logo, then turns off again and again.
- 3. The screen is completely black but your iPhone still vibrates or rings.
- 4. Your iPhone turns off sometimes even when the battery is full.
- 5. The Wi-Fi, Bluetooth or cellular service will not work because these parts are connected to the iPhone logic board.
- 6. The Face ID or Touch ID stops working suddenly and you do not know why.
- 7. Your iPhone gets very hot even when you are not using apps that need a lot of power.
- 8. Charging only works with some cables or it takes a long time to charge even with good cables.
- 9. The camera, speaker or microphone stops working even if you did not drop your iPhone.
Common Causes of Logic Board Failure
- 1. Physical drops.
- 2. Liquid damage.
- 3. Overheating.
- 4. Manufacturing defects.
- 5. Normal wear and aging .
Logic Board Repair:
What It Costs and What to Expect
Logic board repairs are not something you can do at home.
- 1. It requires tools, like micro-soldering equipment and oscilloscopes.
- 2. Need for hands-on experience.
If you try to fix a logic board without the tools, you risk causing more damage. This can make the repair more expensive. It is best to leave logic board repairs to the experts. At National City Phones, we have technicians who have the tools and knowledge to perform all minor to complex repairs with care and precision.
Typical repair costs vary widely:
| Repair Type | Estimated Cost |
|---|---|
| Component-level repair (single chip/IC) | $100 – $250+ |
| Water damage board cleaning & repair | $150 – $400+ |
| No-power issue (power IC replacement) | $150 – $350 |
| Full logic board replacement | $300 – $600+ |
The wide range in pricing reflects the complexity of the specific damage and the model of the iPhone. Newer models (iPhone 8 through 16 series or 17) have more tightly integrated boards, which makes repairs more labor-intensive.
When to Stop DIYing and Bring It to a Professional
There are clear signs that home troubleshooting has reached its limit:
- 1. You've charged it for 60 minutes with multiple cables.
- 2. Force restart does nothing, not even a brief flash of the Apple logo.
- 3. The phone was dropped and has visible damage to buttons or the case.
- 4. There are signs of water damage (red LCI, corrosion on the charging port).
- 5. Recovery Mode either doesn't work or the phone disconnects mid-restore.
- 6. The screen is black, but the phone is clearly still on (sounds/vibrations).
At this point, continuing to push buttons and plug into random chargers isn't going to help and could make things worse. What you need is a trained technician with diagnostic tools who can identify the actual root cause.
