Some of us have been there before: everything seems to be going fine when your iPhone randomly turns off itself, or your iPhone won’t turn on. And it won’t wake up either. In most cases, this is a battery charge issue. (Your iPhone won’t switch on even if there’s 5% battery remaining). But it could also be due to other problems.
We’ve tried to list them out here. Since this is a vague and ambiguous problem, troubleshooting an iPhone not turning on after randomly switching off can take a lot of trial and error. Be sure to hit us up if your iPhone goes kaput, and you need to wake it up.
iPhone Randomly Turns Itself Off: Tips to Fix This Issue
Tip #1. Force Restart your iPhone
A hard reset or force restart can fix a lot of issues on your iPhone. Normally, this method comes to your rescue when your iPhone shuts down on its own, or keeps crashing, or does not charge. Sometimes, the iPhone battery drains quickly, especially after a software update. To solve all these problems, you can force restart your device.
With iPhone 7, Apple changed the method to restart the device. If you have iPhone 6s or earlier models, you can press and hold the sleep/wake button and home button simultaneously to force a restart.
For iPhone 7 and 7 Plus, follow this method to reboot your device. If you own iPhone 8/8 Plus, iPhone X, and later devices, rebooting the device follows another method in the absence of a home button.
Tip #2. Connect to the Wall Charger & Wait
The first thing you’ll need to try out is connecting the iPhone to a wall-charger. It might not necessarily be a battery issue, but this is the first thing to try.
After you connect, don’t expect the iPhone to boot up instantly. You might have to wait for about 5-10 minutes. In some rare cases, it might take up to 20 minutes for the iPhone to boot.
If The iPhone boots up after a while, check the battery icon. If it’s in the red zone, we’re just talking about a battery-issue. Still not (if the battery is above 20%, green), some software issues might have caused the iPhone to shut down abruptly. If the iPhone does not fire up, try pressing the home+sleep/wake button while the iPhone is connected to the wall charger. There is no logic behind this except that the combination usually kicks the iPhone into recovery mode.
If this worked, you should see a “connect to iTunes” screen, which shows a lightning cable and the iTunes icon. When this happens, connect your iPhone to iTunes and proceed to make a recovery/restore. (yes, data is at the risk of being lost unless you’ve backed up before).
Tip #3. Put Your iPhone into DFU Mode
Device Firmware Update (DFU) helps you upgrade your iPhone to the preferred iOS version. Note that DFU mode is different from Recovery Mode, which only installs the latest available iOS version on your iOS device.
Apart from software updates, DFU mode can resolve many adamant issues, which cannot be troubleshot by traditional restore or Recovery Mode. Check this complete guide on how to put your iPhone into DFU mode.
Tip #4. Update Apple Software
There are many instances when the software update has fixed a lot of issues. Random shut-down of your iPhone may have caused by a pending software update. You can check for the iOS update on your device and then download & install Apple’s latest software.
If you have enabled automatic software updates, you are not supposed to hit the trigger every time Apple releases an update.
Before you update your device, you need to take a backup of your iPhone to iTunes.
Tip #5. Check Battery Usage
Frequent battery drains can also shut down your iPhone randomly. This normally happens after a software update, or some apps behave weirdly on the device. In any situation, you can run a check of battery usage on your iPhone. This gives you an understanding of which apps consume more battery on your phone.
Tip #6. iPhone Battery Replacement Program
After checking the battery usage on your iPhone, you must have taken some measures to improve your device’s battery life. However, when your iPhone battery does not improve, you need to go for a battery replacement program. Visit the Apple Support page for battery and power repair, and start a battery replacement.
#4. Check for Physical Damage (Screen, Sleep Button, Home Button, Liquid, etc.)
Physical damage might also cause a random, abrupt switch-off.
Check the Power Button: is it pressed or damaged in some way? If the power button is damaged, it could be causing a circuit issue within the iPhone that could switch it off randomly (and prevent it from switching on)
Liquid damage: in case of your iPhone coming into direct contact with a liquid (most likely, water), the screen circuits might be affected. That might prevent the screen from turning on or displaying anything. Check for indications in the liquid contact indicator.
If there’s liquid-based damage, the warranty won’t cover it, but there’s only one way to get the problem fixed: Apple service center.
When all your attempts fail to yield any result, you should contact Apple as a last resort. Fix an Apple Genius Bar appointment and get tech support.
That’s all, friends!
A sudden shut-down of iPhones is a serious issue, especially while using your device for purchasing an app or any other products/services. I hope this troubleshooting guide can solve the issue.
