How to Fix Slow Charging on Android

Step by step

1. 1 min

   Verify the integrity of the charging port

   Power off the device completely. Use a bright light to inspect the USB-C port for lint, dust, or metallic debris that may obstruct the connection pins. If debris is present, use a non-conductive plastic toothpick to gently dislodge the material, then clear it with a brief burst of compressed air.

   Note: Avoid using metal objects to prevent short-circuiting the charging pins.

   Test the power adapter and cable

   Connect the device to a different high-wattage wall adapter and a known-working USB-IF certified cable. If charging speed increases, the original power accessory is faulty or lacks the required power delivery (PD) profile. Avoid charging via USB ports on computers or hubs, as these deliver significantly lower current.

   Monitor power consumption via Battery settings

   Navigate to Settings > Battery > Battery usage to identify applications consuming excessive background power. High background activity during a charging session forces the OS to throttle input current to manage heat. Force stop or uninstall apps showing anomalous power draw.

   Note: A device running intense processes while plugged in will always charge at a reduced rate.

   Disable Adaptive Charging features

   Access Settings > Battery > Charging optimization. Temporarily toggle off Adaptive Charging or Optimized Battery Charging to test if the OS is intentionally capping the charge rate based on usage patterns. Some devices throttle current to prevent heat buildup when the battery temperature exceeds 40°C.

   Clear the system cache partition

   Power off the phone and boot into Recovery Mode by holding Power and Volume Down simultaneously. Select Wipe Cache Partition using the volume keys and confirm with the Power button. This removes temporary system files that may interfere with battery management firmware.

   Note: This process does not delete your personal data.

   Check for pending firmware updates

   Navigate to Settings > System > Software update to ensure the device is running the latest OS build. Firmware patches often contain critical power management profiles that resolve slow-charging bugs or hardware communication errors. Install all available updates and restart the device.
