iPhone Won’t Power On or Charge? What to Do First
If your iPhone won't power on or charge, start by connecting it to a known-good cable, power adapter, and outlet, then leave it charging for up to one hour before trying again. If nothing changes, force restart it, inspect the charging setup and port, check for liquid or extreme temperature, and then determine whether the problem is the display, software, battery, charging hardware, or another internal component. Avepower recommends service if the phone still does not turn on after these steps.
Why Won’t My iPhone Power On or Charge?
An iPhone that appears completely dead may have a discharged battery, frozen software, a faulty cable or power source, a blocked or damaged charging port, temperature-related charging protection, liquid exposure, a failed display, a worn battery, or another hardware fault.
| What You See | More Likely Cause | What to Do First | When to Escalate |
|---|---|---|---|
| Completely black, no sound or vibration | Deeply discharged battery, charging problem or hardware fault | Known-good charger for up to 1 hour | Still no response after charger and restart tests |
| Low-battery icon appears | Battery is very low but phone is receiving power | Continue charging | Icon never progresses after testing charger/cable |
| Phone rings or vibrates but screen stays black | Display or display connection issue | Force restart and test computer recognition | Screen remains black while phone clearly operates |
| Apple logo appears repeatedly | Startup/software problem | Force restart, then Recovery Mode if needed | Update cannot complete |
| Charging symbol appears but battery does not rise | Weak/faulty power source, temperature, battery or charging issue | Change cable, adapter and outlet | Same result with known-good equipment |
| Liquid-detection alert appears | Moisture in connector/cable/accessory | Disconnect wired charging and let it dry | Alert continues after everything is fully dry |
| Computer recognizes the phone but screen is black | Display/software issue more likely than total power failure | Back up data if possible | Display remains unusable |
| No response from wired or compatible wireless charging | Battery, charging circuit or internal hardware | Force restart and service diagnosis | After known-good charging test |
iPhone Won’t Power On or Charge? 8 Fixes to Try
1. Charge the iPhone With a Known-Good Power Source for Up to One Hour
A completely discharged battery may not produce an immediate response when you connect a charger. Avepower recommends charging an iPhone that will not turn on for one hour, then trying again rather than assuming the battery or phone has failed after only a few minutes.
Use a controlled test:
-
Connect the phone to a wall outlet that you know works.
-
Use a known-good charging cable.
-
Use a compatible, undamaged power adapter.
-
Make sure every connection is firmly seated.
-
Leave the phone connected for up to one hour.
-
Try turning it on again.
Advises checking the cable and USB adapter for damage and trying a different outlet if necessary. Do not continue using accessories with broken insulation, damaged connectors, or bent prongs.
How Long Can the Screen Stay Black After the Battery Dies?
A deeply discharged iPhone does not necessarily show a charging screen immediately. iPhone user guide says an extremely low battery can leave the display blank briefly before the low-battery image appears, and a very low device may need additional charging time before it is usable.
For troubleshooting purposes, use Apple's one-hour charging test rather than deciding that the phone is defective after 10 or 15 minutes.
2. Force Restart the iPhone
A force restart can recover an iPhone whose software has frozen while the display remains black. In that situation, the phone can look completely powered off even though the underlying problem is an unresponsive operating state.
For current iPhones with Face ID and other supported newer models:
Press and quickly release Volume Up → press and quickly release Volume Down → press and hold the Side button until the Apple logo appears.
For iPhone 7 and 7 Plus, hold the Side button + Volume Down until the Apple logo appears.
For iPhone 6s and earlier, hold the Home button + Side/Top button until the Apple logo appears.
A force restart is different from restoring the phone. You are not selecting an erase or factory-reset operation.
3. Test the Cable, Adapter and Outlet Separately
If the iPhone still does not charge, isolate each part of the charging path instead of replacing the battery immediately. A failed cable, adapter or outlet can drain a phone to zero and make a healthy device appear completely dead.
Change one variable at a time:
| Test | What It Helps Identify |
|---|---|
| Same phone + different cable | Cable or connector problem |
| Same cable + different adapter | Power-adapter problem |
| Same setup + different outlet | Outlet problem |
| Known-good charger + same phone | Phone-side charging problem |
| Same charger + another compatible device | Whether the charger actually supplies power |
If several known-good combinations fail only with the affected iPhone, the probability shifts toward a phone-side problem such as the port, battery or internal charging hardware.
4. Check the Charging Port—But Do Not Damage It While Cleaning
Debris can prevent a charging connector from seating correctly, but aggressive cleaning can turn a simple connection problem into physical port damage. Apple advises removing debris from the charging port as part of its charging troubleshooting process.
First inspect the connector with good lighting.
If the plug cannot seat normally or visible debris is packed inside, avoid:
-
metal tools;
-
liquids or cleaning chemicals;
-
forcing the connector;
-
aggressive scraping.
If debris cannot be removed safely without inserting tools deep into the connector, professional cleaning is preferable to damaging the contacts.
5. Check for Liquid Before You Keep Plugging the Cable In
If the iPhone reports liquid in the USB-C or Lightning connector, disconnect the charging cable rather than repeatedly overriding the warning. Charging while connector pins are wet can cause corrosion or permanent connector damage.
Avepower recommends leaving the device in a dry area with airflow and trying again after at least 30 minutes. If the warning returns, moisture may still remain; complete drying can take up to 24 hours.
Do not:
-
use a hair dryer or other external heat source;
-
use compressed air;
-
insert cotton swabs, paper towels or other foreign objects into the port;
-
put the iPhone in rice.
6. Rule Out Temperature-Based Charging Protection
An iPhone can temporarily slow or stop charging when it becomes too hot or too cold. This is a protection feature rather than proof that the charger or battery has failed.
Charging is designed for ambient temperatures around 0°C to 35°C (32°F to 95°F). When the phone is outside an appropriate temperature range, iOS may display “Charging On Hold” and resume automatically after the device returns to a normal temperature.
If temperature is the problem:
Move the phone indoors or out of direct sunlight, disconnect it if it is unusually hot, and let it return to normal temperature naturally.
Do not try to accelerate the process with a refrigerator, freezer, heater, or hair dryer.
7. Check Whether the Phone Is Actually On but the Display Has Failed
If the iPhone rings, vibrates, produces notification sounds, connects to a computer, or otherwise responds while the display remains black, the problem is less likely to be a completely dead battery.
A failed or disconnected display can make a working phone look as though it has no power.
If a Mac or PC detects the iPhone while the screen stays black, prioritize your data:
Back up the device immediately if the computer allows you to do so.
Then arrange display or hardware diagnosis rather than repeatedly attempting battery fixes.
8. Use Recovery Mode Only After Basic Charging and Restart Tests Fail
Recovery Mode is appropriate when the phone reaches an Apple logo or startup screen but cannot boot normally, or when a computer reports that the device needs recovery.
If your computer offers both options:
Try Update first if available.
An Update attempts to reinstall the current system software while preserving data.
Restore erases the iPhone and reinstalls iOS.
How Can You Tell Whether the Charger or the iPhone Is the Problem?
The most reliable home test is to cross-check the phone with more than one known-good power source and cross-check the charger with another compatible device. If multiple working chargers fail only with one iPhone, the likelihood of a phone-side fault increases.
A useful troubleshooting sequence is:
Outlet → adapter → cable → connector → temperature/liquid → software → battery/internal hardware
This avoids paying for a battery or charging-port repair when the actual problem is a $10 cable—or replacing chargers when the phone's display is the failed component.
Can a Power Bank Help if an iPhone Won’t Charge?
A compatible power bank can provide a useful second power source when you are testing whether a wall adapter or outlet is responsible, but it cannot repair a damaged charging port, failed battery or internal hardware. The same cable and connector compatibility rules still apply.
For example, the Avepower K188 5000mAh Mini Power Bank can serve as a compact backup power source when your phone battery is low and a wall outlet is unavailable. It includes a built-in USB-C connector and an integrated 8-Pin charging cable, with both outputs rated at 5V/2A. Its 5000mAh capacity is best suited to emergency top-ups and short-term backup rather than repeated full charges.

For an explanation of capacity, watts, connectors and how portable charging works, see Avepower's What Is a Power Bank? guide.
If you are choosing portable backup power after resolving the phone problem, compare Avepower's Mini Power Bank collection by connector type, capacity and output rather than assuming a larger mAh rating automatically produces faster charging.
When Should You Stop Troubleshooting and Get the iPhone Serviced?
Stop home troubleshooting when the device remains completely unresponsive after a one-hour known-good charging test and correct force restart, when it has significant liquid or impact damage, when the charging connector is physically damaged, or when Recovery Mode cannot update the device.
Other strong service indicators include:
-
the device becomes abnormally hot during charging;
-
it repeatedly shuts down immediately after starting;
-
it is recognized by a computer but the screen never works;
-
Recovery Mode fails repeatedly;
-
buttons required for Recovery Mode are damaged;
-
several known-good charging sources produce no response.
How to Reduce the Chance of This Happening Again
The best prevention is not a special charging trick; it is avoiding repeated situations that make diagnosis difficult. Use undamaged charging equipment, keep connectors dry, avoid extreme temperatures, maintain current backups, and keep access to a reliable secondary power source when you depend heavily on your phone away from outlets.
A portable charger is useful for preventing an ordinary depleted battery from becoming an emergency, but it is not a substitute for repairing a battery, port or internal circuit that is already failing.
Conclusion
If your iPhone won't power on or charge, do not assume immediately that the battery has failed. Start with a known-good charger for up to one hour, perform the correct force restart, isolate the cable, adapter and outlet, inspect the charging port, and rule out liquid and temperature protection.
If the phone vibrates or a computer detects it while the screen remains black, investigate the display. If it reaches the Apple logo but cannot start, use Recovery Mode and try Update before Restore. If there is still no response after the basic tests, professional hardware diagnosis is the safer next step.
Avepower provides portable charging products for users who need backup USB power away from wall outlets. When choosing a power bank, match the connector, individual port output and required capacity to the devices you actually charge rather than choosing by mAh alone. Compare Avepower portable chargers
FAQ
Why won't my iPhone turn on even though it is plugged in?
A deeply discharged battery may need time before the phone responds, while a faulty cable, adapter, charging port, frozen operating system, failed display, or internal hardware fault can produce the same symptom. Apple recommends using a known-good charging setup for up to one hour and then trying a force restart.
How long should I charge a completely dead iPhone before trying to turn it on?
Use up to one hour as the main troubleshooting window. An extremely low battery may initially leave the screen blank, so no immediate charging image does not prove that the phone or battery has failed.
Why is my iPhone screen black but the phone still vibrates?
If it vibrates, rings, or is detected by a computer, the phone may already be powered on, and the problem may involve the display rather than the battery. Try a force restart and back up the device if your computer recognizes it before arranging repair.
Can I use wireless charging if the charging port is not working?
Yes, if your iPhone model supports compatible wireless charging and there is no problem with the back of the device. Wireless charging can also be used while a wet wired connector dries, but the back of the phone must be dry first.
Will Recovery Mode erase my iPhone?
Entering Recovery Mode itself does not erase the device. When a computer offers Update or Restore, try Update first if appropriate. Choosing Restore reinstalls iOS and erases the device.
Can a bad battery make an iPhone stop charging and turning on?
Yes. A degraded or failed battery can eventually prevent normal startup or charging, but you should first rule out the charger, cable, outlet, connector, temperature, and software because they can create similar symptoms. Battery diagnosis is more reliable after those simpler causes have been eliminated.
When should I take an iPhone to Apple or a repair provider?
Seek service if the phone remains unresponsive after a known-good one-hour charging test and correct force restart, has physical or liquid damage, becomes abnormally hot, has a damaged port, or cannot complete Recovery Mode troubleshooting.
