Sony WF-1000XM6 iFixit Teardown

Next slide the bottom off the case.

Removing the bottom we can see the wireless charging coil on the bottom. Like in the WF-1000XM5, the charging coil is soldered to the PCB.

The battery holder is held on with clips around the edge (red arrows).

The lower section of the battery compartment is screwed into the main body with 2 screws. Removing this cover reveals the main case PCB. The PCB is attached with 1 screw located beside the USB-C port.

The main PCB is connected to a smaller secondary PCB via a ribbon cable.

The secondary PCB is held in place with 3 screws, the PCB is labelled as CASE SUB.

The major reveal in the iFixit teardown is that Sony has decided to solder the battery connections to the PCB. In the WF-1000XM5 and WF-1000XM4, Sony used a JST connector for the battery, meaning replacing the battery would be very quick and easy for any user.

This change to a soldered connection is puzzling, as Sony has been using a JST connection on almost all of their new models, like WF-C710N, WH-1000XM6 and the new LinkBuds Clip. Would love to hear the explanation and reason for this change from Sony. iFixit states there is enough room for a JST connection, so even more puzzling.

Here are the battery details, matching what I posted in the FCC teardown update. The battery in this unit is from Springpower.
