Question:

 Why does my Galaxy S20 FE stop charging before it's full?

Answer:

 When wirelessly or plugged in charging, your phone might heat up. This can slow down charge speed or stop charging temporarily. It's like when we're hot, we drink less water. This happens to protect your phone from overheating and is normal. Let it cool down and try charging again.

Terms:

Charging - Giving power to the phone

Overheating - Getting too hot

Ambient air temperature - Room temperature around us
