Sony WF-1000XM3 Battery Replacement

Thanks for the guide! Just replaced the batteries in mine - oddly, the original batteries were “Zenipower Z55”.

Glad I didn't have to throw them out and buy another set (lookin’ at you, Apple and Samsung!)

No idea how you were so smooth with opening the case, took me ten minutes going around in circles for each bud lol

This worked like a charm ? One thing I noticed however: I don’t know if it’s a design chance with later revisions, but when I popped my cover open, the touchscreen and microphone assembly were firmly attached to the cover. Thus, the cover did not separate from the board, like shown in the video. Meaning that if I hadn’t been careful with the plastic picks, I could have accidentally sliced the ribbon cable connecting the touchscreen/mic assembly to the board! Keep that in mind and be careful! Even though these have a difficulty level of “easy”, they are DEFINITELY not meant to be opened and/or repaired!

Thanks reallyhelpful video

but Just becarful when putting the metal thing on the battery because you can short circuit the battery (produce heat and may explode), I think it is safer to first put back the metal thing back in the case then put back the battery (cannot short circuit that way)

It looks like the original battery was the A2 and Varta is now providing the A3 and A4 references: https://www.varta-ag.com/en/industry/pro...

I am thinking to look for the A4 since it may provide additional capacity

CP1254 A3 : 66 mAh

CP1254 A4 : 77 mAh

Very good tutorial!

But I couldn't find any A3, I think they are not sold anymore (at least in France), I managed to find some A4 with a bigger capacity on conrad.fr (ref. CP1254 A4) for 18euro each and it works perfectly well :D
