Had the same with xm4 and managed to get the one earbud replaced. Guess what, the other earbud soon developed the same issue. It's a known problem with xm4Has anyone experienced a battery drain issue with the XM5s? It might be too soon for it to appear. I bought the XM4s in July 2021, and earlier this year noticed that he left bud's battery drains very fast. It's gotten to the point where the left bud will run out of battery in about 1 hour of listening time, while the right bud will still have 80% battery. I'm trying to get Sony to replace it, but since it's out of warranty, I doubt I'll be successful. I'm considering getting the XM5s as replacements, but I'm wary about another battery issue. (I've seen some articles where Sony claims to have fixed the battery problem with the XM5, but no one seems convinced.)

I read somewhere the theory that first xm4s were supplied with a different battery then the latest ones and thus the charging caused that battery to overheat and degrade faster, but also read that some people who had this problem opened their buds and found there the newer battery, so it's a bit contradicting.
So overall personally I got xm5 with an expectation of 1 year of proper service.
