Battery Duration*

Nuance Audio Plus

At original capacity, when fully charged, Nuance Audio Plus features a high-efficiency battery with up to 10+ hours of continuous use. However, battery life depends on how you use your glasses, particularly your Audio Preset, Audio Mode, volume level, and listening environment. Here are some examples:

• In quiet environments (below 50 dB) with Frontal audio mode, Preset A, low volume and around 30 minutes of calls, battery life can reach up to 10 hours and 36 minutes.

• Under typical conditions with moderate background noise (50–65 dB), mixed audio mode, Preset B, medium volume and about an hour of calls, expect around 10 hours and 15 minutes. 

• In noisy settings (above 65 dB) with All-around audio mode, Preset C, higher volume and 90 minutes of calls, battery life is approximately 9 hours and 38 minutes. Presets designed for more demanding listening environments, such as Preset C, require more processing power and therefore use more battery.


Nuance Audio Glasses

At original capacity, when fully charged, Nuance Audio Glasses feature a high-efficiency battery with up to 8 hours of continuous use. However, battery life depends on how you use your glasses, particularly your Audio Preset, volume level, and listening environment. Here are some examples:

• Up to 8 hours in quieter environments (below 50 dB), with lower volume, Preset A and Frontal audio mode.

• 7–8 hours in environments with moderate background noise (50–65 dB) using mixed audio settings.

• 5.5–7 hours in noisy conditions above 65 dB with high volume (4-5/5), Preset C and All-around audio mode.
