Sony WF-1000XM6 FCC Teardown
Here is the assembly from the Sony Engineer interview, which shows both sides.
- This is the board to board connector for the SiP
- Possible battery contacts
- This could suggest a non-soldered battery (unconfirmed)
Battery
That is all the photos from the main internal photo file. Before we look at the wireless module, the reference guide in the FCC filing does provide one detail on the battery. The same information can be found in the Sony Latin America reference manual as well.
The battery model inside the earbuds is “Z55FA”. While no brand is provided, the reference guide from EU support does provide the information about what batteries the WF-1000XM6 is using. I do not remember seeing this information in past reference guides. Guess it is a new EU law, as the WF-1000XM5 reference guide also has battery manufacturer information.
Back to the earbuds, the 4 battery suppliers are:
- Springpower
- Highpower/TH
- VDL
- ZeniPower/ZP
It is pretty obvious that model Z55FA is from ZeniPower, as their previous batteries also use the Z prefix, like Z55FH. This means the new WF-1000XM6 has received a new battery model, 3.85V, but unknown capacity (see update below). The Taiwanese certification is not available yet, but once it appears, we should get the battery capacity information.
