Why Is My Phone Charging Slowly? 12 Reasons & Easy Fixes

Slow charging is one of the most common problems smartphone users face. Whether you’re using an Android or an iPhone, a device that takes too long to charge can be frustrating and can affect your daily routine. In this article, we explain why is my phone charging slowly, the possible causes, and the best solutions to fix it fast.

Why Is My Phone Charging Slowly Due to a Faulty Charging Cable

A damaged, low-quality, or frayed cable often reduces power flow. Even small internal wire breaks can slow down charging drastically.

Fix:

• Use a certified cable (Apple MFi-certified or high-quality USB-C cable)
  
• Avoid very cheap third-party cables
  
• Replace your cable every 4–6 months if heavily used

Weak Power Adapter

Your charger might not support fast charging. If your adapter outputs only 5W or 10W, it will charge slowly.

Fix:

• Check if your phone supports fast charging (18W, 25W, 30W, etc.)
  
• Use an original or compatible fast charger
  

Why Is My Phone Charging Slowly From a Low-Powered USB Port

Charging through:

• laptops
  
• PC USB ports
  
• power banks
  
• car chargers
  may give low power output.
  

Fix:
Plug directly into a wall charger for maximum speed.

Dust in the Charging Port

Dust, lint, or debris inside the charging port can block the connection.

Fix:

• Blow compressed air gently
  
• Use a wooden toothpick to clean (never metal)
  
• Do not use water
  

Why Is My Phone Charging Slowly Due to Background Apps

Apps running in the background drain the battery while it’s charging.

Fix:

• Close unnecessary apps
  
• Turn on Battery Saver
  
• Restart your phone
  

Battery Health Issues

Old batteries charge slower and discharge faster.

Fix:

• Check battery health (Android settings / iPhone Battery Health)
  
• Replace the battery if below 75–80% health
  

Why Is My Phone Charging Slowly When Your Phone Is Overheating

High temperature reduces charging speed to protect the battery.

Fix:

• Remove the phone case while charging
  
• Avoid gaming or using GPS during charging
  
• Charge in a cool, ventilated place
  

Software Bug

Software glitches or outdated OS versions may affect charging speed.

Fix:

• Restart the phone
  
• Update your device
  
• Clear system cache (Android)
  

Slow Wireless Charging

Wireless chargers are inherently slower than wired fast chargers.

Fix:

• Switch to wired charging when possible
  
• Use at least a 15W+ wireless charger
  

Fast Charging Being Disabled

Some phones have “Fast Charging” toggles in settings.

Fix:
Android:
Settings → Battery → More Battery Settings → Enable Fast Charging
iPhone:
Fast charging is automatic — use a 20W+ charger.

Why Is My Phone Charging Slowly Due to Using the Phone While Charging

Gaming, streaming, or heavy usage during charging slows down the process.

Fix:
Avoid using your phone for heavy tasks until it reaches at least 50%.

Poor-Quality Power Source

Old extension boards or weak power sockets may reduce power output.

Fix:
Try another socket or a direct wall outlet.

How to Fix Slow Charging Quickly (Step-by-Step Guide)

Step 1: Try a different cable

This solves the issue in 60% of cases.

Step 2: Clean the charging port

A small piece of lint can block charging pins.

Step 3: Check your charger wattage

If your phone supports 25W but your charger is 10W, it will definitely charge slowly.

Step 4: Turn on Airplane mode

This boosts charging speed instantly.

Step 5: Stop using your phone while charging

Reduces power consumption and speeds up charging.

When Should You Replace Your Charger or Battery?

Replace your charging accessories if:

• Cable gets hot
  
• Phone charges only at certain angles
  
• Adapter overheats or buzzes
  
• Battery drains unusually fast
