If you get them fixed have both batteries replaced at once and make sure they are the same rating

It's a pretty well known issue with the WF-1000XM4.
Unfortunately it took some time to be discovered and it's probably too soon in the WF-1000XM5s product lifespan olto know if it's a widespread issue or not. That's kind of an unfortunate byproduct of the rapid release cycle of BT headphones. The XM5 was probably mostly designed by the time the XM4 issues were discovered.
Ive not heard of any abnormal battery issues with the WH series
It started when Sony went from Varta to Chinese suppliers for true wireless batteries.
I also suspect the truth is true wireless earphones are "too small to be reliable" in current technology, that's why you see far fewer issues with overhead headphones. These products are not on a fast release cycle - the WFXM4 was on the market for two whole years, as were things like Jabra's Elite series.
To small to be reliable is probably true to an extent. But ive had Samsung buds for years with no issues. Some brands seem to have more problems than others.
2 years is a fast release cycle in my mind, and battery issues did not become widespread until a year or so after the product was launched. That was my point. And by that point they probably already knew what they were doing with the XM5 to the point it may be difficult to change.
