What if my phone died and won't turn on or charge?
If you've tried charging your phone and it won't turn on, there may be dust and dirt clogging the charging port or a problem with the USB or lightning cable. Check out our guide for how to clean your phone's charging port if you need more help.
3. Enable Safe Mode
Using Safe Mode for your Android will disable third-party apps that may be causing an issue for your device and—if all goes well—allow it to turn on. For iPhone users, skip to step four.
How to enter Safe Mode on your Android:
Press and hold the Power button.
When your phone begins to boot up, press and hold the Volume down button until you see “Safe Mode” appear on your screen.
To exit Safe Mode, restart your device.
4. Check for damage
Sometimes cracks, breaks, and corrosion on your phone aren't visible right away. Try shining a light on the screen and removing your phone case to check for any physical damage. You can also try calling your device to see if it vibrates or rings. Water damage? Here are 8 ways to dry your phone fast.
5. Perform a factory reset
When your Android or iPhone won't power on, restoring your device to its factory settings may be your only option. But this should be a last resort, after you've tried everything else, because it erases nearly all the data on your device.
If you can't perform a factory reset on your iPhone because of a frozen or black screen, connect it to a computer and use a program like Finder® or iTunes® to enter Recovery Mode. For Samsung Galaxy® S8, newer models, and other devices, you can factory reset your Android phone by following our guide.
