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.
Replaced mine 6mo ago following this guide
Go head and replace both while you're at it.
2pcs ZeniPower Z55H Battery (0.29Wh) and a tube of E-8000 multipurpose adhesive should cost about $25 on ebay.
Here's a decent video tutorial as well.
Legend.
Eh, right place at the right time. Pay it forward.
