If your iPhone 17 stopped charging after installing the iOS 14.3 update, you are not alone. Many users have reported that their devices suddenly refuse to charge or charge very slowly after updating. This can be caused by software glitches, accessory compatibility issues, or even battery management conflicts.
Before assuming it’s a hardware problem, try the fixes below to get your iPhone charging normally again.
Why Your iPhone 17 Might Not Be Charging After the Update
- Temporary software bug from the iOS 14.3 update.
- Lightning cable or charger not working properly.
- Dirt or debris blocking the charging port.
- Optimized Battery Charging delaying full charge.
- Overheating preventing the device from charging.
Check Your Charger and Cable.
The most common cause of charging failure is a faulty or incompatible accessory. iOS updates sometimes tighten safety standards for chargers and cables.
- Try charging your iPhone with the original Apple charger and Lightning cable.
- If that fails, test with another certified Apple or MFi (Made for iPhone) accessory.
If your device starts charging, the issue is likely the old cable or adapter.
Clean the Charging Port.
Lint, dust, and small debris can block the Lightning port, preventing a solid connection between the charger and your phone.
- Turn off your iPhone, and then inspect the charging port under good lighting.
- Use a soft, dry brush or a non-metallic toothpick to gently remove any visible debris.
Avoid blowing into the port or using liquids, as moisture can cause further issues.
Restart Your iPhone.
After an update, system files may temporarily conflict, affecting charging recognition. Restarting clears those temporary glitches.
- Press and hold either volume key and the side key.
- When the power slider appears, drag it to turn off the device. Wait 30 seconds, then hold the side key again to turn it back on.
Once restarted, connect your charger and see if it begins charging normally.
Disable Optimized Battery Charging.
iOS includes a feature called Optimized Battery Charging that pauses charging past 80 percent to reduce battery wear. Sometimes it may interfere with normal charging after an update.
- Open Settings, and then tap Battery.
- Tap Battery Health & Charging, and then toggle off Optimized Battery Charging.
Plug your device in again to see if charging resumes as expected.
Check for a New Update or Patch.
Apple often releases small updates or patches to fix post-update issues like this. Installing the latest version can help.
- Open Settings, and then tap General.
- Tap Software Update, and then select Download and Install if an update is available.
After updating, restart your iPhone before charging again.
Force Restart if iPhone is Completely Unresponsive.
If your iPhone does not respond at all when plugged in, a force restart can help. It refreshes system functions without erasing any data.
- Quickly press and release the Volume Up key, then the Volume Down key.
- Press and hold the Side key until the Apple logo appears.
Reconnect your charger afterward and wait a few minutes to see if it starts charging.
If none of these steps fix the issue, the problem might be with your charging hardware. In that case, contact Apple Support or visit an authorized service provider for assistance.
Your iPhone 17 should charge smoothly again once the software stabilizes and accessories are verified to be compatible with iOS 14.3.
FAQs
Why did my iPhone stop charging after updating to iOS 14.3?
It is usually caused by minor software bugs or accessory compatibility issues introduced during the update process.
Will turning off Optimized Battery Charging harm my phone?
No. It simply allows your iPhone to charge fully without pausing at 80 percent. You can turn it back on anytime.
Should I use third-party chargers?
Only if they are Apple-certified (MFi). Non-certified chargers can cause charging failures or damage the port over time.
