I have Oticon More 2 hearing aids which I purchased in April of 2021. In the last two months or so, I have noticed that one hearing aid loses its charge faster than the other. After an overnight charge, one hearing aid lasts for at least sixteen hours while the other is nearly depleted after about fourteen hours. I have no choice but to give this hearing aid a short charge in order for it to last till the end of my day. I wonder if the battery is failing on this hearing aid, or is there another explanation?
