Why do my hearing aid batteries drain faster than expected?

Last updated on Nov 06, 2025

Several factors can cause faster battery drain: streaming audio via Bluetooth (which significantly increases power consumption), using advanced features like noise reduction or directional microphones, extreme temperatures, high humidity, poor battery contact due to corrosion, or batteries that are old or improperly stored. Weak cell phone signals can also drain batteries faster if your hearing aids are trying to maintain Bluetooth connection. Keep spare batteries handy and consider switching to power-saving modes when extended battery life is needed.
