Battery life with no streaming?

My aids are 8.5 years old. Thinking about getting MFI aids. I currently have 312 batteries. I would stay with this battery size. They currently last 7 days. I would not stream music or TV. I get maybe one phone call per day, but would still appreciate the convenience of hearing the call direct from my hearing aids. Under this scenario, how long would 312 batteries last with MFI aids?

It depends on

  • your hearing loss. (Amount of gain needed.)
  • how many hours per day you wear them.

I wear them 15-16 hours each day.

Newer (more powerful processor) aids will reduce battery life. Think 4-5 days.
