Hello. I have this problem with my speaker that when I play sound on higher levels, the sound becomes saturated. Is it anything battery-related, because everything is fine when I connect charger. So my question is that should I replace battery? Also worth mentioning that one speaker element had hole at some point of it’s life, but I fixed it.
