Ember uses advanced temperature control technology to create an environment where a hot drink (coffee/tea) is able to come to a resting temperature, decided by the user, between 120˚F - 145˚F. Once liquid reaches the user's determined temperature, Ember will work to keep it at that resting temperature until the battery drains.
If a user pours in a drink hotter than their desired temperature, Ember's battery won’t be strained until their drink reaches the desired temperature. When the liquid reaches desired temp, the batteries in the Ember mug will then engage to keep the liquid stable at that temperature. This is an optimal situation to allow for prolonged battery life.
However, if a user pours in a drink cooler than their set desired temperature, the Ember’s battery will be required to engage instantly and will begin working overtime to heat the liquid. While your Ember has the power and capability to complete this task, the battery will diminish significantly faster using this method.
