Sony WF-1000XM6 FCC Teardown

Update

We have battery capacity information from the Taiwanese certification, plus some other details on the Qi coil suppliers.

1. Left/Right earphones
   • Brand/Model: ZeniPower – Z55FA
     • Specification: DC 3.85V, 95mAh
2. Charging case
   • Brand/Model: VDL – 532145PM4
     • Specification: DC 3.85V, 560mAh
   • Springpower – 532145
     • Specifications: DC 3.85V, 560mAh
   • Highpower – 532145
     • Specifications: DC 3.85V, 560mAh

The charging case from the certification shows 5V, 800mA, so it should charge max, 4W. We know the wireless antenna in the earbuds is made by Goertek Inc, so nothing new. but the Qi coil details are new.

Antennas:

1. Left earphone: Monopole Antenna, Brand/Model: Goertek Inc. / ANTENNA L, Antenna Gain: -3.18 dBi
2. Right earphone: Monopole Antenna, Brand/Model: Goertek Inc. / ANTENNA R, Antenna Gain: -2.54 dBi
3. Charging case: Qi Coil Antenna
   1. Brand/Model: TDK Taiwan Corporation / 10237661
   2. Brand/Model: Luxshare Precision Industry Co., Ltd. / 10253641

For comparison, the WF-1000Xm5 earbuds battery was Zenipower Z55FH, 3.85V, 95mAh, so identical but a different battery model. The internal case battery was 3.85V, 500mAh, so smaller capacity.

End of update

Searching for this new battery on Google yields zero results.

Finally, we have one more photo, the SiP.

The SiP is GSBR-005. I hypothesized Sony would move to a new SiP in this post, specifically GSBR-005, and it looks like I was correct. The only information provided, is the version 3-2 of the SiP, and the Bluetooth chip inside, MT2833.

This means the photo from the promo video was misleading.
