iPhone Won't Turn On? 6 Steps to Try Before You Panic
A dead-looking iPhone is usually not dead. Work through these six steps in order, from a force restart to spotting a black screen or swollen battery, before assuming the worst.
Few things are more stressful than pressing the side button and getting nothing back. No Apple logo, no vibration, just a black screen.
The reassuring part: an iPhone that won't turn on is usually not dead. In our Glendale repair shop, most phones that arrive "completely dead" are back on within minutes, and the majority of the rest are fixable the same day. Work through these steps in order before you assume the worst.
Step 1: Force Restart Your iPhone
An iPhone that looks off may actually be frozen with the screen dark. A force restart clears that state without erasing anything.
iPhone 8 and every model since (including iPhone 17 and iPhone Air):
- Press and quickly release the Volume Up button.
- Press and quickly release the Volume Down button.
- Press and hold the Side button. Keep holding through the black screen, even for 20 to 30 seconds, until the Apple logo appears.
iPhone 7 and 7 Plus: hold Volume Down and the Side button together until the logo appears.
iPhone 6s and earlier: hold the Home button and the Side (or Top) button together.
The most common mistake is letting go too early. Hold the last button longer than feels reasonable.
Step 2: Charge It for 30 Minutes, Then Try Again
A battery that has drained to zero will not show the charging screen right away. The phone needs a few minutes of trickle charge before it can even light the display.
- Use a wall adapter, not a laptop port or car charger.
- Use a cable you know works on another device.
- Leave it plugged in for at least 30 minutes without touching it.
- Then try the force restart from Step 1 while it is still plugged in.
If the phone charges but keeps dying within hours, the battery is likely worn out. Our post on iPhone battery replacement cost explains what to expect.
Step 3: Rule Out the Charging Port and Cable
An iPhone that won't turn on or charge often has a charging problem, not a power problem. Look into the port with a flashlight. If you see packed lint, clear it with a wooden toothpick. Our guide on how to clean an iPhone charging port walks through it safely.
If you have a MagSafe or wireless charger, try that. If the phone wakes up on wireless but not on cable, the port is the culprit and a charging port repair will fix it.
Step 4: Check Whether the Phone Is On but the Screen Is Black
Sometimes the iPhone is running perfectly and only the display has failed. Try these tests:
- Call it from another phone. Does it ring or vibrate?
- Toggle the mute switch or Action button. Do you feel the haptic click?
- Ask Siri. Hold the Side button and say something. Does it respond?
- Plug it into a computer. Does Finder or iTunes detect a device?
If the answer to any of these is yes, the phone is alive and you have a screen problem. That is a straightforward screen repair, and your data is safe.
Step 5: Look for Physical Causes
Three physical problems account for most truly dead iPhones we see:
Liquid Damage
Even a phone that "was fine after it dried" can fail days later as corrosion spreads. If the phone has been near water recently, do not keep trying to charge it. Charging a wet board accelerates the damage. Read our water damage first-aid guide and bring it in for liquid damage service as soon as you can.
A Swollen Battery
If the screen is lifting away from the frame on one side, or the phone no longer sits flat, the battery has swollen. Stop charging it immediately and get it replaced. A swollen lithium battery is a safety issue, not just a performance one.
Drop Damage
A hard drop can unseat internal connectors or crack a solder joint even when the glass looks fine. If the phone died right after a fall, it needs to be opened and inspected.
Step 6: Stuck on the Apple Logo or a Boot Loop
If the Apple logo appears and then the phone restarts, freezes, or goes dark again, you have a software or storage issue rather than a dead phone. This often happens after a failed iOS update or when storage is completely full.
Connect the phone to a Mac or PC and use recovery mode to Update (not Restore). Update reinstalls iOS while keeping your data. Only choose Restore if you have a backup, because it erases the phone.
If the update fails repeatedly, or the phone is not recognized by the computer at all, the problem is usually hardware underneath the software and it is time for a professional look.
When to Bring It to a Repair Shop
Come see us if any of these apply:
- The force restart and 30-minute charge did nothing.
- The phone was recently wet, dropped, or is swollen.
- It is stuck in a boot loop and recovery mode does not help.
- It gets warm while plugged in but never turns on.
- You have photos or data on the phone that are not backed up.
That last one matters. Many "dead" iPhones can be brought back long enough to pull your data even if you decide not to repair them. Do not let anyone talk you into a restore or a replacement before your photos are safe.
What We Do When Your iPhone Won't Turn On
At Pro iPhone Repair we start with a free diagnostic. We test the battery under load, check the charging circuit, inspect the board for liquid damage under magnification, and confirm whether the display is the only failure. Then we tell you exactly what is wrong and what it costs before any work begins.
Battery, charging port, and screen failures are typically fixed the same day. Liquid damage is treated with a professional cleaning and dehydration service before we recommend anything else.
Book a free diagnostic in Glendale or walk in. Bring your charger if you can, so we can rule it in or out on the spot.
