In this comprehensive guide, we will unravel the reasons behind this perplexing issue and provide detailed solutions to ensure your iPhone charges efficiently, maintaining its battery health over time.

Understanding the Paradox: Decreasing Battery While Charging

The Significance of Battery Health

As of 2024, with billions of smartphones in use globally, understanding and maintaining battery health has become crucial. Apple, like other smartphone manufacturers, continually strives to enhance battery technology to meet the increasing demands of modern users.

The Conundrum of Decreasing Battery While Charging

Experiencing a decline in battery percentage while the iPhone is plugged in can be attributed to various factors. This paradoxical situation not only disrupts the user experience but also raises concerns about the long-term health of the device's battery.

Reasons Behind Decreasing Battery While Charging

Background Processes and Apps

   - Example Scenario: Numerous background processes and apps running concurrently can lead to increased power consumption.

   - Solution: Identify and close unnecessary background apps by double-clicking the home button (for iPhones with a home button) or using gestures (for iPhones without a home button).

Faulty Charging Cable or Adapter

   - Example Scenario: Damaged charging cables or adapters may not provide a stable power supply, leading to erratic charging behavior.

   - Solution: Use Apple-certified charging cables and adapters. Replace damaged cables or adapters promptly.

Software Glitches or Bugs

   - Example Scenario: Software issues, glitches, or bugs can interfere with the charging process.

   - Solution: Keep iOS updated to the latest version. Perform a soft reset by restarting the iPhone to resolve temporary software issues.

Overheating During Charging

   - Example Scenario: Excessive heat generated during charging can cause the iPhone to limit charging or even discharge the battery.

   - Solution: Ensure proper ventilation during charging. Remove the iPhone case if it retains heat. Avoid charging in direct sunlight.

Battery Health Degradation

   - Example Scenario: Over time, batteries naturally degrade, leading to decreased charging capacity.

   - Solution: Monitor battery health in "Settings" > "Battery" > "Battery Health." Consider replacing the battery if it falls below 80%.

Background App Refresh

   - Example Scenario: Apps refreshing content in the background can contribute to increased power consumption.

   - Solution: Disable unnecessary background app refresh in "Settings" > "General" > "Background App Refresh."

Detailed Solutions to Fix Decreasing Battery While Charging

1. Optimize Background Processes:

 a. Close Background Apps: Double-click the home button (for iPhones with a home button) or use gestures (for iPhones without a home button) to view and close background apps.

 b. Background App Refresh Settings: Disable background app refresh for non-essential apps in "Settings" > "General" > "Background App Refresh."

2. Ensure Quality Charging Accessories

a. Use Certified Cables and Adapters: Use only Apple-certified charging cables and adapters to ensure a stable and efficient charging experience.

 b. Inspect and Replace Damaged Accessories: Regularly inspect charging cables and adapters for damage. Replace any damaged accessories promptly.

3. Software Maintenance

 a. Keep iOS Updated: Ensure your iPhone is running the latest iOS version. Check for updates in "Settings" > "General" > "Software Update."

 b. Soft Reset: Perform a soft reset by restarting your iPhone. For iPhones with a home button, press and hold the power button until the slider appears. For iPhones without a home button, press and hold the side button and either volume button until the slider appears.

4. Manage Heat During Charging

a. Ensure Proper Ventilation: Charge your iPhone in a well-ventilated area to prevent overheating. Avoid charging on soft surfaces that can trap heat.

 b. Remove iPhone Case: If your iPhone gets hot during charging, remove the case to allow better heat dissipation.

5. Monitor and Maintain Battery Health

 a. Check Battery Health: Regularly check your battery health in "Settings" > "Battery" > "Battery Health." Consider replacing the battery if it falls below 80%.

b. Battery Replacement: If your iPhone's battery health is significantly degraded, consider replacing the battery through Apple or an authorized service provider.

6. Fine-Tune Background App Refresh

 a. Disable Unnecessary Refresh: Turn off background app refresh for apps that don't require real-time updates in "Settings" > "General" > "Background App Refresh."

Advanced Troubleshooting Step

1. Reset All Settings: In "Settings" > "General" > "Reset," choose "Reset All Settings" to revert system settings to default. Note: This won't delete data but will reset preferences.

2. Factory Reset and Restore: As a last resort, perform a factory reset in "Settings" > "General" > "Reset" > "Erase All Content and Settings." Restore your iPhone from a backup afterward.

3. Contact Apple Support: If the issue persists, reach out to Apple Support or visit an Apple Store for further assistance.


Mastering the charge on your iPhone involves a holistic approach, addressing specific scenarios and implementing detailed solutions. By understanding the reasons behind decreasing battery while charging and applying these nuanced fixes, you can ensure an efficient and reliable charging experience for your iPhone. Stay empowered, keep your device optimized, and navigate the evolving landscape of smartphone technology with confidence.
