This battery life info came from the Oticon Rep who attended my appt. I actually said 80? Answer: no 50 - 60 depending on streaming. 3 1/2 - 4 days. That is what I get now with my OPN1 and P100 receivers. He said it would be the same. Maybe his answer to me was tailored to my loss and usage. Maybe other people with less hearing loss will get 80 hrs.
FWIW – I have never gotten the Hours of Battery Life any manufacturer, including Oticon, claims. Bluetooth, streaming, power receivers, hearing loss, all contribute to lower battery life.
