When an iPhone won’t turn on, charge it, force restart, then use recovery or DFU mode before booking hardware service.
You pressed the Side button and nothing. No Apple logo, just a black screen. The good news: most no-power moments trace back to a drained battery, a frozen process, or a cable issue. Work through the steps below from quickest to deepest. Each step builds on the last, so you won’t waste time or risk data needlessly.
These steps are safe for recent models, including USB-C phones. Follow the order below to avoid data loss and to separate simple power issues from hardware faults.
Fast Triage: What To Try When An iPhone Does Not Power On
Start here. These actions fix the majority of cases, especially after a full drain or a minor crash.
| Symptom | Likely Cause | Next Step |
|---|---|---|
| Screen stays black | Battery at 0% or system hang | Charge 60 minutes, then force restart |
| Low battery icon appears then vanishes | Weak charger or bad cable | Use an MFi cable and a 20W+ adapter |
| Apple logo loops | Update failed or corrupted system | Enter recovery mode and update |
| Liquid detected alert | Moisture in port or cable | Unplug and allow to dry before charging |
| No charge, port wobbles | Debris or damaged connector | Inspect, gently clear lint, try wireless |
Step 1: Give It A Real, Uninterrupted Charge
Connect to a known-good wall adapter, not a laptop. Use an Apple-certified cable. Leave the phone on the charger for a full hour. If the battery was deeply discharged, the screen may stay blank for several minutes before the logo appears.
If you see the red battery icon and then it flashes off, the power source may be too weak. Swap in a 20W or higher USB-C adapter, or a different cable. For devices with wireless charging, place the phone on a Qi or MagSafe pad to rule out a port fault. If charging still fails, see Apple’s guidance on devices that won’t charge and try a second cable and brick.
Step 2: Force A Restart
A force restart kicks the boot process without erasing data. Button combos vary by model. Try the sequence for your device; hold the final button until the logo appears. Apple documents these sequences in the iPhone User Guide and the no-power article. You can also skim Apple’s no-power steps if you want a quick checklist straight from the source.
Force Restart For Face ID Models
Press and quickly release Volume Up, then Volume Down, then press and hold the Side button until the Apple logo appears. Keep holding even if the screen goes dark first.
Force Restart For iPhone 7 And 7 Plus
Press and hold Side and Volume Down together until the logo shows.
Force Restart For iPhone 6s, SE (1st Gen), And Earlier
Press and hold Home and the Side/Top button together until the logo shows.
Step 3: Update Or Restore With A Computer (Recovery Mode)
If the phone still won’t boot, connect it to a Mac or Windows PC and open Finder, the Apple Devices app, or iTunes depending on your system. With the phone connected, enter recovery mode using the button steps for your model. When the computer shows the prompt, choose Update first to reinstall iOS without wiping data. If the update fails, repeat and choose Restore, which erases and reinstalls the system. Apple’s page on using recovery mode with a computer explains the prompts and timing.
This path helps when the device is stuck on the Apple logo, in a loop, or not recognized properly. Keep the cable connected and avoid bumping the buttons during the process.
How To Enter Recovery Mode
- Face ID models and iPhone 8 series: Press and quickly release Volume Up, then Volume Down, then hold the Side button. Keep holding when you see the logo. Release when the computer symbol appears.
- iPhone 7/7 Plus: Hold Side and Volume Down together. Release when the computer symbol appears.
- iPhone 6s, SE (1st gen), and earlier: Hold Home and Side/Top together until the computer symbol appears.
Use a direct USB port on the computer, not a hub. On a Mac with macOS Catalina or later, use Finder. On a Windows PC, install the Apple Devices app or iTunes. If the download takes longer than 15 minutes, the phone may exit recovery; repeat the steps and start again.
Step 4: Try DFU Only When Recovery Fails
Device Firmware Update (DFU) goes deeper than recovery by reloading low-level firmware along with iOS. It’s a last resort for stubborn software faults or failed updates. Timing is precise. If you prefer not to attempt it, an authorized technician can perform it safely.
General outline for Face ID models: connect the phone to the computer, then press Volume Up, press Volume Down, hold Side for 10 seconds, then hold Volume Down while still holding Side for 5 seconds, then release Side and keep holding Volume Down for about 10 seconds more. The screen stays black; the computer should detect a device in recovery. Restore in Finder or iTunes. If you see the Apple logo, the timing was off—start again or fall back to recovery mode.
Hardware Checks That Save You A Trip
Before booking repair, rule out these quick fixes.
- Inspect the port: Shine a light. If you see fluff, coax it out with a wooden toothpick. Avoid metal tools that can bend pins.
- Test another outlet: A failing power strip can mimic a dead phone.
- Check cable and brick: Borrow known-good parts. Look for frayed insulation or bent pins.
- Try wireless charging: If it charges on a pad but not by cable, the port likely needs service.
- Look for impact signs: A sharp drop can dislodge connectors inside, leading to no-boot behavior.
Liquid And Moisture: Do The Right Thing
If you saw a liquid detection alert or the phone recently got wet, stop charging immediately. Tap the device gently with the connector facing down to let moisture drain, then leave it in a dry area with airflow. Skip rice; particles can enter the port. Don’t use heat or compressed air. Try charging again after at least 30 minutes, and longer if the alert returns.
Black Screen Yet It Rings Or Vibrates
Calls come in and the phone buzzes, but the display stays dark. That points to a display or backlight issue instead of a dead system. Shine a light at an angle to check for a faint image. If you can trigger haptic feedback or hear sounds, back up with a computer, then book display service. A cracked panel or loose display connector can block the boot visuals even when the phone is alive under the glass.
Troubleshooting Timeline You Can Follow
Minute 0–5: Try a known-good charger and cable. Leave it connected. If nothing shows, do the force restart combo once.
Minute 5–60: Let it sit on a wall charger. No tinkering. Many phones revive after enough current flows to wake the battery controller.
Hour 1–2: Attempt a second force restart. If you see the logo and it boots, back up at once. If it loops, move to recovery mode.
Hour 2–3: Connect to a computer, enter recovery, and choose Update. If it fails, repeat and choose Restore.
After 3 hours: If recovery fails or the phone won’t be detected, consider DFU or schedule service. Bring notes on what you tried.
Model-By-Model Button Combos (Quick Reference)
| iPhone Models | Force Restart Combo | Notes |
|---|---|---|
| iPhone 8 and later, all Face ID models | Vol Up → Vol Down → hold Side | Hold Side past black screen |
| iPhone 7 / 7 Plus | Hold Side + Vol Down | Keep holding until logo |
| iPhone 6s, SE (1st gen), earlier | Hold Home + Side/Top | Release at logo |
Data Safety And Backups
If the device starts after an update, back up at once. Use iCloud Backup or connect to a computer for an encrypted Finder/iTunes backup. Encrypted backups include Health and Keychain data. If you must restore, having a recent backup turns a stressful day into a minor speed bump. For long-term health, keep an eye on battery capacity in Settings > Battery > Battery Health & Charging.
Smart Prevention For Next Time
Two habits prevent most emergency mornings: keep automatic updates on, and avoid running the battery to zero. Replace aging batteries once capacity dips and random shutdowns arrive. Use certified chargers. Store a spare cable in your bag or car. When accessories look worn, retire them before they cause intermittent charging. Keep a small power bank handy for travel.
Spare Parts And Service Choices
When a repair is needed, choose an authorized provider. Genuine batteries and ports match the phone’s power profile and thermal limits. Some aftermarket parts fit, yet they can bring lower capacity, poor calibration, or loose connectors that trigger repeat shutdowns. If a fresh battery doesn’t help, ask the shop to check the charge port, the power management circuits, and the display backlight line. Clear notes on symptoms and the steps you tried will speed up diagnostics and keep costs lower.
Final Checks Before Booking Repair
Run through this list so you hand a technician a clear picture:
- Note when the issue started and what was happening right before it.
- List any drops, repairs, or screen replacements.
- Say which steps you tried in order and what each did.
- Bring the charger and cable you used for testing.
- If possible, bring a recent backup or your iCloud login details.
