Hearing Aid Battery Life Calculator
Estimate battery duration from your hearing aid's stated runtime, daily use and an adjustable streaming assumption.
Your day. Your battery estimate.
Model selection labels your estimate only. The numbers below are editable examples, not specifications for the selected model. Use its manual or your own observed runtime.
Starkey Genesis AI RIC RT
1.7 days of use
23.2 estimated wearing hours. Rechargeable aids should normally be charged daily; this is not a recommendation to skip charging.
Formula: runtime ÷ (daily wear + streaming hours × extra drain). No manufacturer drain rate is assumed. Temperature, receiver power, battery age and wireless features change actual runtime.
Frequently asked
Can this diagnose hearing loss?
No. Uncalibrated devices, headphones and listening environments affect what you hear. An audiologist can measure hearing thresholds and investigate symptoms.
What if my hearing changed suddenly?
Sudden hearing loss needs urgent medical assessment. Do not wait for an online result. New one-sided symptoms, dizziness, pain or drainage also need medical advice.
