Phone charging very slowly

4.5

The phone takes 5+ hours to reach a full charge, or barely gains percentage while in use.

Symptoms
  • "Slow charging" notification
  • Heat while charging
  • Battery drain > Charge rate

Step-by-Step Fix

1

Use Original Charger

Switch to a high-wattage (20W+) PD or QC charger.

2

Clean Charging Port

Remove lint that might be preventing a solid connection.

3

Turn Off Screen

Charging is much faster when the device is not being used.

When to See a Technician

Charging from a computer USB port is limited to 0.5A, which is very slow for modern phones.
