iPhone 7 Plus Charging Slowly After iOS 11 Update? Here’s How to Fix It

If your iPhone 7 Plus is charging painfully slow after updating to iOS 11, you’re not alone. Many users have reported sluggish charging behavior post-update — and while some of these issues stem from faulty cables or power sources, others are caused by software glitches. Here’s how to troubleshoot and fix your iPhone 7 Plus if it suddenly stopped charging efficiently.


🔌 Step 1: Check Your Charging Hardware First

Before diving into software fixes, rule out the basics:

✅ Inspect the Cable and Adapter

  • Look for bent pins, fraying, or burn marks
  • Use Apple-certified accessories only
  • Try a different charging cable and wall adapter

✅ Avoid Charging from USB Ports

  • USB ports on laptops or hubs offer limited power and can slow charging
  • Plug directly into a wall socket using the proper adapter

✅ Clean the Charging Port

  • Use a flashlight to check for lint or dust
  • Gently clean with a dry toothbrush or anti-static brush

⚙️ Step 2: Restart or Force Restart Your iPhone

Sometimes a minor software glitch slows down the charge response.

✅ Soft Reset:

  • Hold the Power (Side) button
  • Slide to power off
  • Wait 30 seconds, then power back on

✅ Force Restart:

  • Hold the Volume Down + Power buttons together for 10 seconds
  • Release when the Apple logo appears

After the restart, plug your iPhone back in and check the charging response.


📲 Step 3: Check for Software Updates

Apple may release a follow-up patch to fix post-update bugs.

  • Go to Settings > General > Software Update
  • If an update is available, install it
  • Make sure your iPhone is charged or connected to a power source during the update

🔧 Step 4: Reset All Settings

This resets your iPhone settings without erasing data — great for fixing glitches that occurred after updates.

  • Go to Settings > General > Transfer or Reset iPhone > Reset
  • Tap Reset All Settings
  • Enter your passcode and confirm

Then plug in your iPhone and observe if it charges faster.


💡 Step 5: Give It Time to Charge

If your battery was completely drained, your iPhone might take a few minutes before showing signs of life. Let it sit plugged in for at least 30 minutes before assuming it’s not charging.


💻 Step 6: Restore iOS via iTunes (Optional)

If the issue persists and began right after updating to iOS 11, consider a clean restore:

  1. Backup your iPhone using iTunes or iCloud
  2. Open iTunes on your computer
  3. Connect your iPhone via Lightning cable
  4. Select your iPhone > click Restore iPhone
  5. Follow the on-screen instructions to reinstall iOS

You can also use Recovery Mode or DFU Mode for deeper-level restores if needed.


🧪 Still Charging Slowly?

If none of these fixes work:

  • Test another power outlet or try charging from a friend’s Apple charger
  • If the phone charges normally with different equipment, you’ve isolated the problem
  • If the issue continues, your iPhone may have a battery or logic board issue — contact Apple Support or visit a Genius Bar
