A phone that stays black after charging is either not getting usable power, deeply discharged, frozen, stuck during startup, or running with a blank display. Start with the power checks, then use the exact button reset or recovery path for your device.
Here are the fixes that apply to current iPhone, Android, Samsung Galaxy, Motorola, and Pixel phones.
Give the battery a real charging window
Use this first when the phone has been dead for a while, shows a black screen, or flashes a low-battery symbol before going dark. A deeply discharged phone needs time on a working charger before the power button brings it back.
For iPhone, plug it in and charge for one hour. If the low-charge battery appears, check the iPhone hardware and keep charging for 30 minutes or until it starts.
For Samsung Galaxy, connect the phone to a wall outlet with a Samsung-certified charger and cable. Wait at least 30 minutes, then press and hold the Power button.
For Motorola, use the supplied charger and make sure the cable fits snugly in the phone and charger. Charge for about 15 to 20 minutes, and skip computer USB charging here because Motorola says that charges much more slowly.
Check the charger cable outlet and port
The charging setup is the first thing to rule out when the phone still looks dead. Try charging another device with the same power adapter and cable.
Make sure the cable is firmly connected to the adapter and the phone. Then try a different cable or power adapter.
Look inside the charging port for dust or lint. On a Samsung Galaxy, power the device off when possible, inspect the port with a flashlight, and gently blow out debris without using sharp objects.
Check the phone for cracks, swelling, or signs of water exposure. If you see damage, stop and move to service.
Force restart the phone
Once the phone has charged, use the restart command that matches your device.
- 1.iPhone with Face ID: press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the Apple logo appears.
- 2.Android: hold the Power button for 5 to 7 seconds.
- 3.Samsung Galaxy: press and hold the Side key and Volume Down together for more than 7 seconds until the Samsung logo appears.
- 4.Motorola: press and hold the Power key for 10 seconds. If it does not restart, keep it connected to a wall charger and try again.
If a Samsung Galaxy opens Maintenance Boot Mode, use Volume Up and Volume Down to select Normal Boot, then press the Side key.
Find out if the screen is the problem
The most common display clue is simple: the phone rings, vibrates, or makes sounds while the screen stays black.
For Android, press and hold the Power button for about 35 seconds, then wait about 2 minutes. Call the phone from another phone, or use Find Hub to ring it.
In Find Hub, sign in on another Android phone, tablet, or browser, choose the device, and select Play sound. The phone rings at full volume for 5 minutes when it has power, a network connection, Google Account sign-in, Find Hub turned on, and Google Play visibility.
For Samsung Galaxy, plug the charger into a wall outlet and watch for the charging indicator. If the screen stays dark, check whether the phone makes sounds, rings, or vibrates during calls or notifications.
If the phone rings or vibrates but the screen stays blank, treat it as a display failure and contact a local authorized repair center.
Try computer charging on Android
Use a computer USB or USB-C port when wall charging gives no response and the cable works. The computer must be on and connected to power.
Connect the phone to the computer and wait about 10 to 15 minutes. Disconnect the cable from the phone, then reconnect it within 10 seconds.
If a battery icon appears within one minute, charge for at least 30 minutes. Press and hold Power until the phone restarts, then tap Restart when the option appears.
If no battery icon or restart option appears, repeat the charger, cable, outlet, and port checks before using software recovery.
Use Android button recovery while plugged in
Use this when an Android phone reacts to button presses or shows a red light, flashing red light, Android robot, or Start screen while plugged in. Button behavior varies by manufacturer, so follow the screen your phone shows.
With the phone plugged in, press and hold Volume Down and Power together for at least 20 seconds. If you see a red light, charge for at least 30 minutes, then press and hold Power for a few seconds and tap Restart.
If you see an Android robot and Start with an arrow, press Volume Down until Power off appears, then press Power to select it. Charge for at least 30 minutes, then press and hold Power or tap Restart.
Pixel owners with Pixel 4a or later, including Fold, can connect the phone to a computer and open Google’s Pixel Update and Software Repair tool. Follow the on-screen instructions to manually update software to the latest version without a factory reset in supported cases, or reset the phone to the most recent Android version.
Use iPhone recovery mode when startup is stuck
Use recovery mode when the iPhone connects to a computer or reaches a startup or recovery screen.
- 1.Connect the iPhone to a computer and open Finder on Mac or the Apple Devices app on Windows.
- 2.For iPhone 8 or later, including iPhone SE 2nd generation and later, press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the Connect to computer screen appears.
- 3.Find the iPhone on the computer.
- 4.Choose Update when the Update or Restore options appear.
- 5.Choose Restore only if Update does not fix startup, because Restore erases data and reinstalls iOS.
If the computer download takes more than 15 minutes and the iPhone exits recovery mode, let the download finish, then repeat the recovery-mode steps. Windows users who do not have Apple Devices should get it from Apple’s official Windows download page.
Run Samsung emergency recovery after a failed update
Samsung Smart Switch emergency recovery is for Galaxy phones recognized by Smart Switch after a failed software update or an emergency recovery screen. It is not a general fix for a phone that is totally dead.
Unplug the phone from the computer and close Smart Switch. Restart Smart Switch, open MORE, choose Emergency Software Recovery and Initialization, select the device listed for emergency recovery, read the information, and select OK.
When emergency recovery fails on the original computer, use the recovery code on another computer. On the first computer, open MORE, choose Emergency Software Recovery and Initialization, and write down the emergency recovery code; on the other computer, choose Emergency recovery using the recovery code, enter the code, read the information, and select OK.
If Smart Switch does not recognize the phone or the phone still will not power on, stop using emergency recovery and contact Samsung Support or visit a Samsung Service Center.
Skip outdated fixes and get service
The most common mistake is following old repair advice for a modern sealed phone.
Do not remove a Samsung battery unless the device has a removable battery. Do not use Samsung Kies for modern Galaxy recovery; Samsung’s current path is Smart Switch. Do not open a current Motorola phone to remove or replace the battery.
If an iPhone still will not turn on after force restart and charging, use Apple’s service flow. If a Samsung Galaxy still will not power on after charging checks, port checks, damage checks, and forced restart, contact Samsung Support or visit a Samsung Service Center.
If this fails on a work or school phone, contact your organization’s IT support. Managed devices have recovery requirements handled by the organization.
