If your iPhone 17e is completely black and won't respond, the first thing to try is a force restart. It's the quickest way to clear a temporary software hang. Press and quickly release the Volume Up button, then press and quickly release the Volume Down button. Finally, press and hold the Side button. Keep holding it until you see the Apple logo appear on the screen, then you can let go.
This process is a bit different from older iPhones, so don't worry if it feels new. It forces the device to reboot without affecting your data.
Check Your Charger and Cable
Your phone might simply have a dead battery. Since the iPhone 17e uses a USB-C port, grab a known-good USB-C to USB-C cable and a compatible power adapter. Plug it into a wall outlet and check that the cable and adapter are firmly connected.
If it won't turn on, let it charge for one hour before trying again. The 17e supports fast charging with a 20W or higher adapter and a USB-C cable. While it charges, look for the charging symbol, a small battery icon, to appear on the screen. If you see nothing, try a different cable or power adapter.
Also, if you're using a MagSafe charger, make sure it's properly aligned on the back of the phone. The 17e supports both MagSafe and the newer Qi2 standard. Remove any thick or metal cases, as they can interfere with the magnetic connection or wireless charging coils.
Inspect the Charging Port
Take a close look at the USB-C port on the bottom of your iPhone 17e. Shine a light inside and check for any packed-in lint, dust, or debris. This is a common issue that can prevent the cable from seating fully and making a connection.
If you see anything, you can very carefully try to remove it. Use a dry, soft-bristled brush. Avoid using anything metal like a paperclip, as you could easily damage the delicate pins inside the port.
Try a Different Power Source
Sometimes the problem isn't your phone, but the outlet or charging gear. Plug your cable and charger into a different wall socket. If you can, try a completely different charging setup, a friend's USB-C charger, for example.
This helps rule out a faulty power adapter or a problematic cable. Check the cable and adapter for damage, including broken connectors or bent prongs, and stop using any damaged accessories. A compatible 20W or higher adapter can fast-charge the 17e.
Connect to a Computer
If the screen stays black, connect your iPhone 17e using a USB-C cable that supports data and charging, then open the Finder on a Mac or the Apple Devices app or iTunes on a Windows PC. Listen for a connection sound from the computer or watch for any detection prompts.
If the computer doesn't recognize the phone, try another USB cable that supports data and charging, another USB port, or another computer. On a Mac, click Allow if an 'Allow accessory to connect?' alert appears. If the computer offers Update or Restore, follow the recovery mode steps below.
Warm Up the Device
If you've been in a very cold environment, the cold can temporarily affect battery performance. Bring your iPhone 17e inside to room temperature and let it sit for a while before trying to charge or turn it on again.
Don't use external heat sources like a hairdryer or heater, as excessive heat can permanently damage the battery. Just let it warm up naturally. The A19 chip in the 17e can run warm during heavy use, but it shouldn't get excessively hot just sitting idle.
Perform a Recovery Mode Restore
If the force restart did nothing, recovery mode may help, including when a computer doesn't recognize the phone. Try Update first; Restore will erase all data on the phone, so it's a last resort before seeking service.
First, update your Mac or install the latest Apple Devices app on your Windows PC. Connect the phone with a USB cable, then open the Finder on your Mac or the Apple Devices app on your PC. Press and quickly release the volume up button, then press and quickly release the volume down button. Hold the side button until the 'Connect to computer' screen appears, even after the Apple logo appears.
On your computer, you'll be given the option to Update or Restore. Choose Update to reinstall iOS without erasing your data. If that fails, you may need to choose Restore, which reinstalls iOS and erases everything. Before restoring, check whether you have an existing iCloud or computer backup to recover your data afterward.
Consider Software Issues
If your iPhone turns on again, back it up and check Settings > General > Software Update for the latest version of iOS. If an update is available, connect to power and Wi-Fi, then tap Download and Install.
If you're still using recovery mode and the software download takes more than 15 minutes, the phone may leave the 'Connect to computer' screen. Let the download finish, then repeat the recovery mode button sequence above. If the phone still won't turn on or recovery mode cannot update or restore it, arrange service.
