After upgrading their iPhones to iOS 17/18, many users are eager to update their systems to experience the new features. However, a number of users have found that their iPhones cannot charge properly after the upgrade, which can be quite frustrating. This article will analyze the reasons why the iPhone won't charge after iOS 17/18 update and provide various effective solutions to help you resolve the issue as quickly as possible.

Part 1. Why iPhone Won't Charge After iOS 17/18 Update?

The reasons why an iPhone may fail to charge after an iOS 17/18 update could include the following:

• Charging cable or adapter issues: Non-original or damaged charging equipment may cause charging failures.
• Dust or damage in the charging port: Dust or foreign objects blocking the charging port can disrupt the flow of electricity.
• Declining battery health: Aging or damaged batteries can directly impact charging performance.
• System malfunctions or software issues: Errors during the system upgrade process may lead to widespread charging problems.

Part 2. How to Fix iPhone Won't Charge After iOS 17/18 Update

After identifying the possible causes, here are the specific steps to help you resolve the charging issue on your iPhone after the iOS 17/18 update.

Fix 1. Check the Charging Cable and Adapter

Prioritize using the official Apple charger for charging, and ensure that the charging cable and adapter are not damaged or excessively worn. Non-official or damaged charging equipment may lead to insufficient current, preventing the device from charging.

Fix 2. Clean the Charging Port of the iPhone

One common cause of charging problems is a dirty or blocked charging port. Over time, dust, lint, or debris can build up in the port, hindering a proper connection with the charging cable. Use a soft-bristle brush to gently clean out dust and debris from the charging port. Be careful not to damage the metal contacts inside the port during the process.

Fix 3. Try Using a Different Power Source

Sometimes, unstable current from the power outlet or USB port can also affect charging. Try plugging into a different outlet or switching to another USB port on your computer to see if it resolves the charging issue.

Fix 4. Check the Health of the iPhone Battery

A decline in battery health can directly affect your iPhone's charging ability. After upgrading to iOS 17/18, the battery's workload may increase, so it's advisable to regularly check the battery status and replace aging batteries promptly.

Here are the steps:

Step 1. Go to "Settings" > "Battery" > "Battery Health".

Step 2. Check the maximum capacity of the battery, ensuring it's above 80%.

Step 3. If the battery capacity is too low, it's recommended to visit an Apple Authorized Service Provider for a battery replacement.

Fix 5. Disable Optimized Battery Charging

Optimized Battery Charging is a feature introduced by Apple in iOS 13 and later. When activated, your iPhone will pause charging at 80%. To charge your iPhone to 100%, follow these steps to disable this feature:

Step 1. Go to "Settings" > "Battery" > "Battery Health & Charging".

Step 2. Turn off "Optimized Battery Charging" if you want to fully charge your iPhone.

Fix 6. Force Restart the iPhone

Force restarting your iPhone can clear system caches and resolve certain temporary software issues, potentially restoring charging functionality.

To force restart your iPhone, follow the steps below:

iPhone 8 and later:

• Quickly press and release the "Volume Up" button.
• Quickly press and release the "Volume Down" button.
• Press and hold the "Side" button until the Apple logo appears.

iPhone 7 / 7 Plus:

• Press and hold the "Volume Down" button and the "Power" button simultaneously.
• Keep holding until the Apple logo appears.

iPhone 6s and earlier:

• Press and hold the "Power" button and the "Home" button simultaneously.
• Continue holding until the Apple logo appears.

Fix 7. Reset the iPhone Settings

iOS 18 updates may introduce new system settings that can cause certain functions to behave abnormally. Resetting your iPhone settings can restore the default configuration and resolve charging issues.

Here is how to do it:

Step 1. Go to "Settings" > "General" > "Transfer or Reset iPhone" > "Reset" > "Reset All Settings".

Step 2. Enter your password and confirm the reset.

Step 3. After the reset is complete, reconnect the iPhone to the charger for testing.

Fix 8. Update iOS

After an iOS upgrade, Apple usually releases minor updates to fix bugs. If your iPhone is not charging, it might be due to a system bug, so it's recommended to check for updates to the latest version.

To update your iPhone, follow the steps below:

Step 1. Go to "Settings" > "General" > "Software Update". (iPhone software update failed?)

Step 2. Check for any new system updates and follow the prompts to install.

Step 3. After the update is complete, reconnect the charger to see if it works.

Fix 9. Restore iPhone Using iTunes

If the above methods are ineffective, you can use iTunes to restore your iPhone to factory settings. This will erase all data, so be sure to back up your iPhone before proceeding.

Here's how it works:

Step 1. Connect your iPhone to your computer and open iTunes.

Step 2. Click the device icon and select "Restore iPhone".

Step 3. Follow the on-screen prompts to complete the restore process.
