My iPhone won't turn on - WTF?

Let’s be realistic… iPhone and iPad haven’t fallen from the skies… but indeed were created at «Job’s garage». It means Apple products are not ideal as they might look. All Apple products may glitch or crash as the rest of gadgets. If you got to the point when your iPhone won’t turn ON, read this article to the very end. Let’s figure out all possible causes and find the right solution. Don’t panic, relax and keep reading… We are going to fix it together!

If iPhone was dropped from a balcony or washed with a pair of jeans, I doubt this article will be a big help. Such a serious damage may have destroyed your gadget. So you’d better stop guessing «Why my iPhone won’t turn on?» and take it to Apple Care services or repair center for final verdict.

Obviously there should be a reason if an iPhone stopped working… but it’s not possible to give a single solution for every possible cause. It all depends on symptoms coming from your device. In this article we are going to cover most common of them.

iPhone won’t turn on… I see black screen only!

I personally never came across such problem, but many other users had their iPhones stuck in “switched off” condition. At the same time it looks like the phone doesn’t respond to physical buttons. Whatever buttons you press, iPhone screen stays black. Usually this problem is caused by fully drained iPhone’s battery or crashed operating system (iOS). In a very rare case the firmware may get corrupted or internal components fail, but we’ll talk about this a bit later. To sort out your iPhone, try to do the following steps.

STEP 0 If you used your iPhone in really cold weather (we talk about temperatures below zero), then most likely this is the reason why the iPhone doesn’t turn on. You had to know that Li-Ion batteries are not “friendly” with cold weather… especially Apple phones. To resolve this step, warm up the iPhone in your hands up to the room temperature. Avoid placing the device on heating radiators… You’ll get it cooked.

STEP 1 Connect the iPhone to a charger and leave it charging for at least 15 minutes. If the problem was in a drained battery, the iPhone will turn on automatically after battery gets enough charge. If not, proceed to STEP 2.

STEP 2 This is the main STEP in this tutorial, thus it will require some of your attention. The implementation depends of the model of your iPhone.

iPhone 4S/6S: Press and hold HOME + POWER buttons for 15 seconds
iPhone 7: Press and hold POWER and - volume buttons for 15 seconds
iPhone 8/X: Press and quickly release + volume, press and quickly release - volume, then press and hold SIDE button (ex. POWER button) for 15 seconds.

If you did everything correct, you should see Apple logo on the screen. Sometimes it takes longer than 20 seconds so be patient. When Apple logo appears, release buttons and wait for iOS to boot up.

STEP 3 If holding both buttons doesn’t help, try to toggle the silent switch few times. Then go back to Step 2. No-one can really tell why, but it did really help to many users.

If none of the above helped to turn on your iPhone, the problem might be with one of the following:

  • iPhone internal components failed
  • charger or USB cable failed

It’s time to find another charger and give it a try. I’m not making fuss with all these chargers and cables. Recently I scrapped an Apple’s original USB cable, that wouldn’t charge my iPhone for more than 60%. It’s normal for the cable to get damaged due to intense usage. As we all know, Apple never made their cables any durable or robust…

If you really care about your iPhone, I highly recommend to USE ONLY ORIGINAL APPLE CHARGERS. I can say from my own experience that cheap Chinese chargers are easy to melt and even catch a fire. It concerns all kind of chargers (220V, 110V and 24V).

App crash…

It’s rare but still possible to find an iOS app that stopped responding or just hangs. In this case it may help to force that App out of the device’s memory. To do so double press the HOME button to see all running apps, then swipe up in front of the app that hanged. The problematic application will be removed from the memory and then you can try to restart it again.
Frozen iOS application

This kind of problem usually occurs on older devices (such as iPhone 4S or iPad 3), and may be caused by CPU overload or running out of RAM.

iPhone wouldn’t respond to any buttons

Few times I’ve had my iPhone 4S not responding to any physical buttons. iPhone would have a frozen screen with an image of last used app. If you find your device in same condition, just do a Hard Reset (don’t know how? – read here). If you have no time to read, then press and hold HOME + POWER buttons for at least 15 seconds until iPhone reboots. If you have iPhone 7, then press and hold POWER + "-" Volume

Permanent iPhone boot loop

Another “popular” problem is when iPhone is stuck in endless Boot Loop. In other words, your iPhone tries to boot up, but in the middle of the process it crashes and starts booting up over and over again… Usually you would see an Apple logo on the screen for some time, then black screen, then logo again… and so on. Most common cause of the problem is failed iOS update/restore or crashed Jailbraking process. In most cases this problem can be sorted by restoring an iPhone in RECOVERY MODE. To do so follow these steps:

STEP 1 Start iTunes on the computer and plug in the USB cable (don’t connect iPhone to USB cable yet).

STEP 2 Turn OFF the iPhone by holding HOME + POWER buttons until the screen goes black.

STEP 3 Press and hold HOME button, then connect USB cable to iPhone.

STEP 4 Keep holding HOME button until you see “Connect to iTunes” screen on your iPhone (iTunes logo with a cable connector).

STEP 5 The message window will pop up in iTunes. Press Check button.
Connect iPhone to iTunes

STEP 6 Now you can either Restore or Update your iPhone. Since you’re having problems with the firmware, you MUST ONLY PRESS RESTORE button.

What if none of the above worked?

If nothing of the above worked for you, there is one more thing to try – recover the iPhone in DFU (Device Firmware Update) mode. Follow the link for a step-by-step guide. It’s not complicated as it might sound.

What? Still having problems with your iPhone or iPad? Then I would suggest you to visit an Apple Care specialist or at least some Phone Repair shop (only if Apple Care is not available in your region).
