Embr Wave is designed to give about 15-50 sessions of warming/cooling on a full charge.
The actual battery life will depend on a range of factors including things like the environmental conditions, intensity of warming/cooling sessions, and frequency of usage.
We’ve calculated a rough estimate of the battery consumption based on selected duration, wave sensation, and temperature settings to help you better understand how much power you may be using for each session. Generally speaking, stronger temperature levels and longer session durations will consume more power.
Here’s an approximate guide to the number of sessions you can expect to run on a full battery charge:
Low battery consumption: 30 sessions or more
Medium battery consumption: 10-30 sessions
High battery consumption: 10 sessions or fewer
You can view the battery consumption of your current session in the app:
Tapping the (?) will give you a reminder of what High, Medium, and Low mean!
Li-ion batteries can also see their capacity go down by 50% in very cold weather (you might have noticed this with your smartphone, too). Embr Wave is designed to operate in moderate environments. If you're using your device in very cold or very hot environments, that's okay, but it does mean it's probably using more power and depleting the battery faster.
While your Embr Wave is charging, it will pulse green until fully charged, which takes about 1.5 hours. Once your Embr Wave has fully charged, the light bar will shine solid green.
