📋 Difficulty & Time
🔧 Diagnose & Fix Charging Issues: Step by Step
Step 1: Try a Different Cable AND Adapter
Cables fail more often than ports. Borrow a known-good cable from a friend, or grab a spare. Use a different wall adapter too — counterfeit chargers are a common silent killer.
Step 2: Inspect the Charging Port with a Flashlight
Hold the device under a bright light and look directly into the port. You're looking for:
- Gray pocket lint compressed against the back wall (most common)
- Bent or recessed pins (drop damage)
- Green corrosion on the contacts (liquid damage)
- Stuck-on residue from sticky drinks
Step 3: Clean the Port with a Plastic Pick
Power the device OFF first — this prevents short-circuits while you work. Then:
- Insert a plastic precision pick at a slight downward angle
- Work toward the back wall, then drag forward to pull lint OUT (never push deeper)
- Repeat from different angles — port lint is layered
- NEVER use metal — paperclips, needles, or pins will short the contacts
Step 4: Brush + Compressed Air
After picking visible debris, sweep the port with a soft anti-static brush, then short bursts (1 sec) of compressed air from 6 inches away. Keep the can upright to avoid propellant spray.
Step 5: Try Wireless Charging
If the device supports MagSafe/Qi: try wireless charging. If wireless works but wired doesn't, the port is dead — you need replacement (see escalation below). If wireless ALSO doesn't work, the issue is likely the battery or charging IC.
Step 6: Force Restart
Sometimes iOS/iPadOS gets stuck in a charging-block state. Force restart resets the power management chip:
- iPhone 8 and later: press Vol Up, then Vol Down, then hold Side until Apple logo
- iPad with no Home button: same as iPhone 8+
- iPad with Home button: hold Top + Home until Apple logo
⚠️ Common Mistakes to Avoid
- Pushing lint deeper instead of pulling it out
- Using metal tools (instant short risk)
- Skipping the cable test — cables fail more than ports
- Cleaning while the device is powered on
🏥 When to Call a Pro
If the port has bent pins, visible corrosion, or the contacts feel loose, you need a replacement (Apple: $129, third-party: $79–$99, AppleCare+: $99). Skip DIY for this — bent contacts can damage the logic board.
Fixes to Try
1 Force Close and Reopen the App
- Swipe up from bottom and pause (or double-click Home button)
- Find the crashing app
- Swipe up on it to close
- Open the app again
2 Update the App
Developers fix bugs in app updates:
- Open App Store
- Tap your profile icon at top right
- Scroll down to see pending updates
- Tap Update next to the crashing app (or Update All)
3 Restart Your iPhone
Clears memory and stops stuck processes:
- Hold Side + Volume Down
- Slide to power off
- Wait 30 seconds
- Turn back on
4 Free Up Storage
Low storage causes crashes:
- Go to Settings → General → iPhone Storage
- Target at least 2-5GB free space
- Delete unused apps, photos, or clear cache
See our full guide: Free Up iPhone Storage
5 Update iOS
iOS updates fix system bugs that cause app crashes:
- Go to Settings → General → Software Update
- Install any available updates
6 Delete and Reinstall the App
Fresh install fixes corrupted app files:
- Long-press the app icon
- Tap Remove App → Delete App
- Go to App Store and reinstall it
- Sign back in if needed
7 Check App Compatibility
Old apps may not work on new iOS:
- Check app's App Store page for iOS requirements
- If app hasn't been updated in years, it may be abandoned
- Look for alternative apps that are actively maintained
8 Reset All Settings
If multiple apps crash (doesn't erase data):
- Go to Settings → General → Transfer or Reset iPhone
- Tap Reset → Reset All Settings
If All Apps Are Crashing
When every app crashes, the problem is usually iOS itself:
- Make sure iOS is fully updated
- Try a full restart (not just sleep/wake)
- As last resort: backup and restore via computer
Prevent Future Crashes
- Keep apps updated (enable automatic updates)
- Keep iOS updated
- Maintain at least 2-5GB free storage
- Restart iPhone weekly
- Delete apps you don't use
Apps Still Crashing?
If apps continue to crash after trying all fixes, there may be a deeper software issue.
