If the issue is caused by a hardware problem, it may worsen over time and lead to permanent damage to your device and data loss.

Why is your iPhone screen black but still on

Some common hardware issues that can cause the iPhone's black screen of death issue include problems with the display, the battery, or the power button. If you dropped or somehow got your iPhone wet, it could cause hardware damage that leads to a black screen.If you suspect that the black screen issue is caused by a software problem, you can try some basic troubleshooting steps such as force restarting your iPhone, charging your phone, or updating your iOS. However, if you think that a hardware problem causes the issue, it may require professional repair or replacement of the affected component.

Problem: Low-battery iPhone

A simple issue that is easy to resolve is if the black screen in your iPhone is due to a low battery. In this case, follow these easy tips:

Solution 1: Charge your iPhone

Connect your iPhone to a charger and let it charge for at least 30 minutes. If your iPhone's battery is completely drained, it may take some time to accumulate enough power to display the charging screen. You should see a lightning bolt in or beside the battery icon at the top right of the iPhone's lock screen. If there is no lightning bolt in sight, it's not charging. In this case, it can be a hardware issue.

Solution 2: Check your charging cable and adapter

Make sure your charging cable and USB adapter are in good condition and functioning properly. Check for signs of damage, like breakage or bent prongs. If you're using a third-party accessory, check that it's Apple-certified. Test different cables, adapters, and outlets to make sure the problem is indeed with your iPhone.

Solution 3: Try a different power source

If you're charging your iPhone from a computer's USB port, make sure the computer is fully awake (not in sleep or hibernation mode). Also try a different USB port, in case the USB port you were using has failed. Don't try charging from a USB port built into a keyboard or USB hub — connect it directly to a USB port on the computer itself.

Solution 7: Try DFU restore with iTunes

DFU (Device Firmware Update) restore is a deeper restore mode than the recovery mode on your iPhone. It reloads the software and firmware of your device and can help fix software and app issues (especially in the case of iOS Jailbreak).Connect your iPhone to your computer using a USB cable, then press and hold both the Home button and the Lock button (on iPhone 6s and below, iPhone SE, and iPod touch) or the Volume Down button (on iPhone 7 and 7 Plus) at the same time for 8 seconds.After that, release the Lock button (on iPhone 6s and below, iPhone SE, and iPod touch) or the Volume Down button (on iPhone 7 and 7 Plus) but continue holding the Home button for another 5 seconds.If your iPhone screen remains black, it means that you have successfully entered DFU mode. iTunes will detect your iPhone in DFU mode and prompt you to restore it.Click on the "Restore iPhone" button in iTunes to start the DFU restore process. Wait for the restore process to complete. This may take several minutes.Once the restore process is complete, set up your iPhone as new or restore from a backup.
