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:
- Backup your iPhone using iTunes or iCloud
- Open iTunes on your computer
- Connect your iPhone via Lightning cable
- Select your iPhone > click Restore iPhone
- 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
