How long can I expect my battery to last?

The Ember Mug² has an expected battery life of 90 min without the charging coaster at a target temperature of 57°C.

Please note, battery life for the Ember Mug² can vary dramatically depending on a few factors such as pour temperature (we recommend at least 74°C for best results), ambient temperature, desired temperature, and if there are any additions to your beverage.
