iPhone Won’t Turn On? Here Is How to Fix It
A black screen that will not respond is scary, especially when your photos and messages feel like they are trapped inside. Take a breath first. Most of the time, an iPhone won’t turn on because of a drained battery or a small software hiccup, not a broken phone.
This guide walks through the fixes in the order you should try them, starting with the one that takes ten seconds and ending with the point where it makes sense to call Apple. No tech background needed; just follow along step by step, and you will likely have a working phone again before you finish reading.
Why Your iPhone Won’t Turn On
Before jumping into fixes, it helps to know the usual causes behind an iPhone won’t turn on situation. A dead battery is the most common reason by far, especially if the phone was already low before it went dark. A frozen app or system glitch can also make the screen look off even though the phone is technically still on underneath. Less often, a damaged charging cable or port stops power from reaching the battery at all, which looks identical to a dead phone from the outside.
The First Thing to Try: Force Restart
A force restart is the fastest fix when an iPhone won’t turn on because of a frozen app or a stuck process, and it does not touch any of your photos or files. The steps depend on your model.
iPhone 8 and newer (Face ID or side-button models):
- Press and quickly release Volume Up.
- Press and quickly release Volume Down.
- Hold the side button until the Apple logo appears, which can take ten seconds or more.
iPhone 7 and 7 Plus: Hold the side button and Volume Down together until the Apple logo shows up.
iPhone 6s and earlier: Hold the Home button and the side button together until the Apple logo appears.
If you use a force restart often or want the full breakdown for every model, our dedicated guide to restarting an iPhone covers that in more depth. Here, the short version above is usually all it takes.
If Force Restart Does Not Work: Charge It
If nothing happens after a force restart, your iPhone won’t turn on simply because the battery has nothing left to give.
- Use the original cable if you still have it, or a certified replacement.
- Plug it into a wall adapter, not a laptop, since wall power charges faster.
- Leave it alone for a full hour without checking it every five minutes.
- Look for a battery icon or charging animation. It can take ten minutes or longer to appear on a badly drained battery.
- Try turning it on again once the hour is up.
Seeing nothing at all for the first few minutes is normal. Resist the urge to unplug and replug repeatedly, since that can interrupt the slow trickle charge a very dead battery needs to wake back up.
Check the Cable, Adapter, and Outlet
If charging is not doing anything after an hour, the reason your iPhone won’t turn on might be your equipment rather than the phone itself.
- Try a different cable, since bent or frayed cables fail internally without showing visible damage.
- Try a different wall adapter, since these die more often than people expect.
- Try a different outlet, in case the one you are using has no power at all.
Swapping one part at a time tells you exactly where the problem is instead of guessing.
Still Stuck? Try Recovery Mode
If your iPhone won’t turn on after a force restart and a full charge, recovery mode is the next step up. It uses a computer to reinstall the software without erasing your data in most cases.
- Connect your iPhone to a Mac or PC with a cable.
- Open Finder on a Mac, or iTunes on a PC.
- Force restart your iPhone using the steps above, but keep holding the final button until you see the recovery mode screen instead of letting go at the Apple logo.
- When your computer detects the phone, you will see an option to Restore or Update. Choose Update first, since this tries to reinstall the software without wiping your data.
- Let the process finish, then check if your phone turns on normally.
If Update does not work and you are given no other option, Restore is the last resort. It does erase the phone, so only use it if you have a backup or have exhausted every other option first.
What to Check Before You Panic
- Charging port debris. Pocket lint and dust build up more than people realize. Look inside with a flashlight and clean it gently with a dry toothbrush or a wooden toothpick, never anything metal.
- A different cable you know works. Borrowing one from a friend rules out your cable as the culprit in seconds.
- Signs of heat or damage. A charging block that feels hot, a cracked screen, or a bent port point toward a hardware issue rather than something you can fix with software steps.
When to Get Professional Help
Some situations are worth taking straight to an Apple Store or an authorized repair shop instead of troubleshooting further at home:
- The phone still will not turn on after trying everything above.
- The screen shows a red, blue, or otherwise strange colored screen instead of staying black.
- The phone gets unusually hot while charging or just sitting idle.
- There is visible screen damage or a cracked back.
- The phone was recently exposed to water or heavy moisture.
- The charging port looks bent, pushed in, or physically damaged.
Apple’s technicians can run diagnostics that check the battery and internal components directly, which is not something you can do from home. If liquid got inside, do not keep trying to charge it, since that can cause more damage. Get it looked at as soon as you can instead.
Could an Old Battery Be the Real Reason?
Sometimes an iPhone won’t turn on because the battery has quietly aged out, not because of any single event. Batteries lose capacity over time, and once health drops low enough, a phone can shut off unexpectedly and struggle to power back on even with a full charge.
If your phone has been slow to charge or dying faster than it used to for weeks before this happened, that pattern points toward battery wear rather than a one-time glitch. You can check this later once your phone is working again by going to Settings, Battery, Battery Health and Charging, and looking at the maximum capacity percentage.
Preventing This From Happening Again
A little bit of routine keeps an iPhone from turning on the scare from happening in the first place. Charge your phone before it drops below 20 percent instead of letting it run all the way to zero on a regular basis, since deep discharges add up over time and wear the battery faster.
Stick with a certified cable and adapter rather than the cheapest option you can find, and give your charging port an occasional gentle clean if you carry your phone in a pocket full of lint or sand. None of this takes more than a minute here and there, and it is far less hassle than staring at a black screen again.
Final Thoughts
Most of the time, an iPhone won’t turn on because of a dead battery or a stuck process, and both of those are fixable without any special tools. Start with a force restart, move to charging it for a full hour if that does not help, then work through the cable and recovery mode steps before assuming the worst. Keeping your phone above 20 percent charge day to day is a simple habit that helps you avoid landing back here again.
Frequently Asked Questions
How long should I charge my iPhone before trying to turn it on again?
Give it a full hour on a wall charger before checking. A completely drained battery sometimes needs that long before it shows any sign of life.
Will a force restart delete my photos or data?
No. A force restart only restarts the software. Your photos, messages, and everything else stay exactly where they are.
Why is my iPhone showing a red battery icon?
That means the battery is critically low and needs more charging time before the phone can turn on normally. Give it another 30 minutes and check again.
Can a bad charging cable really stop my iPhone completely?
Yes. A damaged cable can look fine on the outside while failing to deliver any power at all. Swapping in a different cable is one of the fastest ways to rule this out.
What if my iPhone feels hot while charging?
A little warmth is normal. If it feels genuinely hot, unplug it right away and let it cool down before trying again, then have the battery checked at an Apple Store if it keeps happening.
