Now you have to desolder the sensor connection and both the connections to the red led at the top.

The white plastic pins left and right to the led connections can easily melt!

Then desolder the connections to the charging coil.

Be careful not to touch nearby electronic components, as they could get damaged!

And keep the soldering time short and remove the soldering iron as soon as the solder has become liquid, so there is no overheating risk!
