You're not wrong, but I have no noticeable issues with my QC35 or AirPods after 2 years. the battery life on the QC35 is simply astounding. I once wore them on a transatlantic flight including lounge stays. Got to my destination after 16+ hours of them being on the entire time, save 60mins during a nap. Some noise cancelling, lots of podcasts and music... Battery was at 60% still.
