Unfortunately I have excessive battery drain in the left earbud of my Sony WF XM4 set. I really like these earbuds and I am going to at least try to fix them. Has anyone here done any thing like this before?
It makes sense, honestly, that the left runs down faster than the right, I use just the left at work all day everyday and only use the right at home maybe once a week. The left lasts 2.5 hours, the right lasts six or more.
I had these and had the same battery problem. I ordered some replacement batteries and replaced the one that was having issues. They were great again for a while. Then the other one started having issues. Then I accidentally damaged the ribbon cable while taking that one apart. Now they're junk. I'm still pissed about it. It would have been so easy for them to make replacing the batteries easy.
Unfortunately they make obscene money selling these, and allowing the user to replace the batteries easily does not equal selling more sets. Your average user would likely just purchase a new set.
