How to Fix Slow Charging on iPhone: A Complete Guide
Introduction
Is your iPhone charging slower than usual? According to Apple Support forums, nearly 67% of slow charging issues are caused by software glitches or system errors rather than hardware faults. While it’s easy to assume that a faulty cable or an aging battery is to blame, the real culprit is often hidden deep within iOS power management.
In this guide, we’ll explore the common reasons why your iPhone might be charging slowly and provide step-by-step solutions to restore normal charging speed. From basic troubleshooting to advanced software repair, we’ll cover it all—including how MagFone iOS System Recovery can fix deep system errors without data loss.
Common Issues Affecting iPhone Charging Speed
If your iPhone is taking forever to charge, one of these factors could be the cause:
Dirty or Blocked Charging Port
Over time, dust and debris can accumulate in the Lightning or USB-C port, preventing a proper connection between the charger and your device.Non-MFi Certified Accessories
Using third-party cables and adapters that aren’t Apple-certified (MFi) can result in limited power delivery, slower charging, or even damage to your device.Software Glitches
iOS power management errors, such as "PMU Controller Error" or "ChargeLoopTimeout," can disrupt charging by causing power data misalignment.
- Battery Health Degradation
If your iPhone’s battery health drops below 80%, charging efficiency decreases, making it take longer to reach a full charge.
Solution 1: Basic Troubleshooting Steps
Before diving into complex fixes, try these simple solutions:
Clean the Charging Port: Use a soft brush or toothpick to gently remove any lint or dust from the port.
Use Apple-Certified Accessories: Always opt for MFi-certified cables and adapters to ensure proper power flow.
Restart Your iPhone: A restart can close background apps and clear minor software glitches that might be affecting charging.
If your iPhone is still charging slowly, move on to software-based fixes.
Solution 2: Restore iPhone via iTunes or Finder
If your iPhone’s charging issues are caused by system errors, a full restore can help reset the device and eliminate software-related problems.
Steps to Restore iPhone:
Connect your iPhone to a Mac or Windows PC using a USB cable.
Open iTunes (or Finder if using macOS Catalina or later).
Put your iPhone into Recovery Mode:
For iPhone 8 and later: Press and release Volume Up, then Volume Down, then hold Power Button until you see the Recovery Mode screen.
For iPhone 7 series: Hold Volume Down + Power at the same time.
For iPhone 6s and earlier: Hold Home + Power until the Recovery Mode screen appears.
