what to do when iPhone won’t turn on is the central topic of this article, and the following content explains the key points, practical uses, and decisions around it.
A dead, unresponsive iPhone can disrupt every part of your daily life, from work deadlines to personal connections, leaving you scrambling for solutions. If you’re stuck with a device that won’t power up, knowing what to do when iPhone won’t turn on is the first step to resolving the issue quickly, avoiding unnecessary repair costs, and getting back to using your phone as normal.
Basic First Steps to Rule Out Minor Glitches
Before diving into complex troubleshooting, start with the simplest checks that often fix unresponsive iPhones. Many power-on issues stem from temporary software freezes, drained batteries, or minor connection issues that don’t require professional intervention. For example, iPhones often display a black screen when the battery is fully depleted, even if it appears dead, so ruling out a drained battery is critical before moving to other steps. It’s also a good idea to check if your iPhone’s screen is cracked, as a broken display can sometimes prevent the device from detecting button presses, making it appear unresponsive even when it’s receiving power. If your device’s screen stays black for more than a minute after plugging in, it’s likely still not charging properly, which means you’ll need to dig deeper into charging-related fixes.
Charging-Related Issues That Prevent iPhones From Turning On
According to Apple’s 2023 Global Repair Trend Report, nearly 60% of iPhone power-off failures are linked to faulty charging accessories or power sources. Common issues here include non-certified cables, damaged adapters, or dead wall outlets that don’t deliver enough power to a fully depleted device. Addressing these issues is often as simple as swapping out a cable or testing a different outlet, and it can save you from wasting time on more advanced fixes.
Inspect Your Charging Cable and Adapter
Frayed, bent, or cheap third-party charging cables are one of the most common causes of charging failures. Apple requires all MFi (Made for iPhone) certified accessories to meet strict safety and performance standards, ensuring they deliver consistent power to your device. Non-certified cables often have internal wiring that breaks easily with frequent use, leading to intermittent charging or no power at all. Check your cable for visible damage, or borrow an MFi-certified cable from a friend to test if your device starts charging.
Test a Different Power Source
Even a good cable won’t work if the power source is faulty. Wall outlets can die or have loose connections, while some computer USB ports only deliver 2.5W of power – less than the 5W required to charge a dead iPhone. If you’ve been charging your phone from a USB port, try plugging it into a wall outlet with a compatible Apple adapter. You can also test the outlet by plugging in another device, like a lamp, to confirm it’s working.
Force Restart Your iPhone to Fix Software Freezes
A frozen or corrupted software process can make your iPhone appear dead, even if the battery is fine. Force restarting your device clears temporary glitches that prevent it from powering on, and it’s a step that works for nearly all models. The method for force restarting varies by iPhone model, so it’s important to follow the correct steps for your device to avoid any issues. Below is a clear, step-by-step guide for all current iPhone generations:
- For iPhone 8, iPhone SE (2nd generation or later), and all newer models (including iPhone 15, iPhone 14 series): Quickly press and release the Volume Up button, then quickly press and release the Volume Down button, then press and hold the Side button until you see the Apple logo appear on the screen.
- For iPhone 7 and iPhone 7 Plus: Press and hold both the Side button and Volume Down button for at least 10 seconds, until the Apple logo displays.
- For iPhone 6s or older models, including the first-generation iPhone SE: Press and hold both the Home button and Top (or Side) button for at least 10 seconds, until the Apple logo appears.
If your iPhone turns on after a force restart, avoid installing any pending iOS updates immediately, as updates can sometimes cause temporary power issues. Wait a day to install updates, and ensure you’re connected to a stable power source during the process to prevent interruptions.
Advanced Hardware Checks for Persistent Power Issues
If none of the above steps work, the issue may be hardware-related, rather than a software or charging problem. Common hardware issues include water damage, a faulty internal battery, or a broken power button. These require careful inspection to diagnose, and some can be addressed without professional help if you’re comfortable with basic disassembly (though we recommend professional repair for most users to avoid further damage).
Check for Liquid Damage
iPhones are water-resistant, but not waterproof, and exposure to liquid (even small spills, high humidity, or submersion) can trigger internal sensors that disable the power function to prevent short circuits. To check for liquid damage, locate the Liquid Contact Indicator (LCI) in the SIM tray slot: for most iPhones, it’s a small white dot that turns red when exposed to liquid. If the LCI is red, do not attempt to charge or power on your device, as this can cause permanent damage. Instead, place the iPhone in a sealed bag of uncooked rice for 24 to 48 hours to absorb excess moisture, then try charging it again to see if the device turns on.
When to Seek Professional Repair for an iPhone That Won’t Turn On
If you’ve tried all the above steps and your iPhone still won’t turn on, the issue is likely a major hardware problem that requires professional repair. Common issues here include a faulty logic board (the device’s internal motherboard), a broken power button, or a swollen battery – a rare but serious issue that can cause the screen to bulge and pose safety risks. Apple’s official support is the most reliable option for warranty-covered devices, and repairs are often free for defects in materials or workmanship. For out-of-warranty devices, third-party repair services may offer lower prices, but always ensure they use genuine Apple parts to avoid compatibility issues that can shorten your device’s lifespan or cause further damage.
When you’re dealing with an unresponsive iPhone, the key is to start simple: check your charging accessories, force a restart, and rule out minor issues before moving to more complex checks. Knowing what to do when iPhone won’t turn on saves you time, avoids unnecessary costs, and helps you get your device back to working order quickly. For persistent issues, professional repair is always a safe bet to prevent further damage to your phone and ensure it functions as intended.
