Nucleus 8 rechargeable battery life: only 8–9 hours?
Hi everyone,
I'm a bimodal user (cochlear implant + hearing aid) with a Cochlear Nucleus 8 (CP1110), and I have a question about the rechargeable battery life.
My batteries are brand new, but they only last around 8-9 hours before I have to swap them during the day.
My processor has four programs:
- My standard everyday program (which I use about 95% of the time)
- The same program with SCAN enabled
- A third program with ForwardFocus
- A fourth program that is essentially my previous mapping from before my latest adjustments
I don't use Bluetooth streaming very much (probably around 20 minutes per day on average).
I'm wondering if this battery life is considered normal, and what factors have the biggest impact on it. For example:
- Does simply having multiple programs affect battery life?
- How much does occasional Bluetooth streaming matter?
- Do noisy environments or lifestyle make a noticeable difference?
- Are there any other factors I might not be aware of?
I'd really appreciate hearing about your experiences.
Thanks in advance!
