I recently moved from Bernafon Zerena to Oticon Real and I notice the battery wear down looks interesting.
Left one is Bernafon Zerena. Right one is Oticon Real.
Bernafon battery. This is fully depleted after 4-5 days use.
Oticon battery. Also fully depleted after 5 days use.
Oticon Real barely scratch the battery surface! Bernafon Zerena looks like its try to grind and destroy battery. Is this normal?
I don’t have issue. Just battery looks different and it catch my eye.
