@1Bluejay P100 is just the OP suggestion, not sure if even Phonak have thought about it, unless if OP is phonak’s matrix agent, in this case he is taking us for Mr Anderson; I ain’t taking the blue pill btw.
If you want more power from your Audeo Lumity, then the best course is to see your HCP, as from your audiogram, the Audeo Lumity still has some margin, me thinking.
On the battery side, well, that’s what we are babbling about, we want the HA manufacturer to respect their user/patients base and provide long lasting rechargeable HA (long lasting, not sure how you will get people to agree on a minimum run time, 24h? 48h? 72?.. how long is good enough, bearing in mind that the rechargeable batteries will degrade over time, and most aren’t user serviceable), and COMMITMENT in providing same HA portfolio but with disposable batteries, NO DISCRIMINATION.
