In the lower-left corner, there is a flexible antenna for NFC communication, and at the bottom is the PCBA module.
A large amount of gray thermal paste covers the heat-generating core components.
The yellow FPC flexible antenna is marked with “24*14_8V11.”
The wireless charging coil is denser and thinner than conventional coils and is connected to the PCBA via a flexible ribbon cable.
Yellow insulating tape is used along the edge of the battery cell to secure the thermistor.
The battery tabs are solidly soldered to the PCB and insulated with high-temperature tape.
Remove the PCB, charging coil, and NFC antenna.
Remove the battery cell.
