Phonak Audeo P70 13T with UP receivers: right side died yesterday, almost exactly 7 days after starting my trial with them. The left died a day later. That’s with moderate streaming (a few hours per day). I was actually surprised the difference between left and right was as small as it was. I expected it’d be bigger considering the right side handles the bluetooth connection.
Previous aids were Phonak Bolero V50 SP with integrated receivers. Those lasted closer to 10-11 days I think. More than a week but definitely not two.
Both with size 13 batteries.
