You press the power button, and nothing happens. No logo, no vibration, no light. It is a stomach-dropping moment, especially if everything on that phone is not backed up.
The good news is that a phone that won’t turn on is often not dead. In many cases the battery is simply drained far below what the charger can wake up instantly, or the software has crashed in a way a restart can clear. This guide walks through why your phone won’t turn on, what to check first, and nine fixes in the order that makes the most sense to try them.
First, Work Out What “Won’t Turn On” Actually Means
Before you try anything, spend one minute checking for signs of life. The answer changes what you should do next.
- Does it vibrate or make a sound when you press the power button or plug it in? If yes, the phone is probably running, and the display is the problem. Read our guide on a black phone screen instead.
- Does it show a logo and then restart in a loop? That points to a software or update problem, not a dead battery.
- Is it warm, or does a charging light come on? That suggests power is reaching the phone.
- Absolutely nothing, even after charging? Continue with the fixes below.
Why Won’t My Phone Turn On? The Most Common Causes
A deeply drained battery. A phone left at 0% for a long time can need a while on the charger before it shows any sign of life. This situation catches people out because they plug it in, see nothing for a minute, and assume it is broken.
A software crash or failed update can also be a reason for this. Frayed cables, weak adapters, and ports clogged with pocket lint are a very common reason a phone looks dead when it just is not charging.

A software crash or a failed update can also cause the phone to appear dead. If the operating system freezes during startup or an update gets interrupted, the phone can hang before it ever lights the screen.
Overheating. Many phones shut down to protect themselves when they get too hot, and some will refuse to power on again until they cool.
Physical or liquid damage. A drop can loosen internal connectors, and moisture can corrode the board or short the battery.
An aging battery. Batteries wear out. An old one may show a charge level and then cut out suddenly, or fail to deliver enough power to boot.
9 Fixes When Your Phone Won’t Turn On
1. Charge it for at least 30 minutes.
Plug the phone into a wall outlet using the original or a known-good cable and adapter. Then wait. Leave it for 15 to 30 minutes before pressing anything, and give it up to an hour if the battery is fully drained. Some phones show a low-battery image first, and some show nothing until they have enough charge to start.
If you can, try a different outlet and a different cable. Computers and power banks can supply too little power for a drained phone, so use a wall adapter for this test.
2. Check and clean the charging port
Shine a flashlight into the port. Compacted lint is surprisingly common, especially for phones carried in pockets. Power the phone off if it is on, then gently clear debris with a wooden or plastic toothpick. Avoid metal pins, which can damage the contacts, and never use liquids or compressed air at close range.
3. Force restart the phone.
A force restart cuts power to the system rather than asking the software to shut down, so it works even when the phone is frozen or half-crashed.
- iPhone 8 and later: press and release Volume Up, press and release Volume Down, then hold the side button until the Apple logo appears.
- iPhone 7: Hold the volume down and the side button together until the logo appears.
- iPhone 6s and earlier: hold the Home button and the top or side button together.
- Android: hold the power button for 20 to 30 seconds. On many Samsung phones, hold the volume down and the side key together for about seven seconds.
If the phone is charging while you do this, keep it plugged in.
4. Remove the case and disconnect accessories.
Take off the case, unplug anything attached, and remove the SIM tray only if you are comfortable doing so. A thick case can trap heat, and a faulty accessory can sometimes interfere with startup. If your phone has a removable battery, take it out for about a minute and put it back in.
5. Let the phone cool down or warm up.
If the phone was in a hot car, in direct sun, or under heavy use, let it sit in a cool, shaded place for a while before charging. Very cold weather has the opposite effect: a battery that is too cold may not deliver power properly until it returns to room temperature.

6. Check for water damage.
Look for moisture in the charging port and SIM tray. If you suspect the phone got wet, do not plug it in. Charging a wet phone can cause permanent damage. Dry the outside, leave it in open air, and avoid the old rice trick, since Apple specifically advises against it. If it stays dead, a repair shop is the right next step.
7. Try recovery mode or a computer connection.
If the phone shows signs of life but will not finish booting, the software may need repair.
- iPhone: Connect it to a Mac or PC (Finder or the Apple Devices app on Windows) and follow Apple’s steps for recovery mode on your specific model. Choose Update first, because it tries to reinstall iOS without erasing your data.
- Android: many phones can boot into a recovery menu using a button combination such as Volume Up plus Power, though the exact keys differ by brand. From there you may find options like wiping the cache partition (on models that still offer it) or, as a last resort, a factory reset.
A factory reset erases the phone, so treat it as a final option.
8. Look for a swollen battery
If the back panel is bulging, the screen is lifting, or the phone looks slightly puffed up, the battery may be swelling. Stop charging it and do not try to press it flat. A swollen battery is a safety issue, and it should be handled by a qualified repair service.
9. Get a professional diagnosis
If none of this works, the cause is probably hardware: a dead battery, a damaged charging port, a failed power button, or a motherboard fault. An authorized service center can test the battery and board, and they will usually tell you whether a repair makes sense compared with the phone’s value. Ask about data recovery before agreeing to anything that wipes the device.
What to Do If You Need Your Data
If the phone will not turn on and you were never backing up, say so clearly at the repair counter. Technicians can sometimes recover data even when the phone is not worth repairing. Do not keep trying random fixes that could make recovery harder, such as factory resets.
How to Stop This Happening Again
- Avoid letting the battery sit at 0% for long periods.
- Use certified cables and chargers from the manufacturer or a reputable brand.
- Keep the charging port clean.
- Install system updates while the phone has plenty of charge, and do not interrupt them.
- Turn on automatic cloud backup so a dead phone never means lost photos and files.
Conclusion
When your phone won’t turn on, work from the cheapest, safest fix to the most drastic: charge it properly, clean the port, force restart, and only then move on to recovery tools or a repair shop. Most of the time the problem is power delivery or a software hang rather than a truly dead phone. If it is still unresponsive after these steps, stop experimenting and get it looked at, particularly if there is any sign of water damage or a swollen battery.
