The battery life of the Ellie Smart Pill Box varies by user, depending on usage and environmental factors.
Most notably, the more alarms scheduled over a given period of time, the shorter the battery life of the Ellie will be. This is because when an alarm triggers, the Ellie is brought into a higher energy state, in order to power the lights and sounds that compose an alarm.
These processes require significantly more power than the base, low-energy state of Ellie; therefore, if having a longer battery life is a high priority for you, try to schedule your alarms in a way that will maximize the amount of time Ellie is running in its efficient, low-energy state.
Here's an example use case to give some perspective, allowing you to better gauge what the battery life might look like in the context of your own, unique use case:
One user has three alarms scheduled every day, and they experience a battery life of about a week.
In practice, here are a couple ways that you could adjust your Ellie usage to extend its battery life:
Whenever possible, schedule doses of different medications at the same time, combining them into a single alarm. This will result in fewer total alarms, and effectively reduce the number of times the Ellie has to enter a high-energy state, as well as the amount of time spent in that inefficient mode.
Make an effort to respond to alarms and disable them as quickly as possible, to further extend the battery life of your pillbox. If you can cut down the length of your alarms, and keep it out of the high-energy state as much as possible. Also, find ways to make it easier for you to respond to alarms quickly, like always keeping the pillbox near you at all times.
Another thing you could do would be to set separate alarms on your phone, a couple minutes before the alarms on the pillbox, which would allow you to anticipate your alarms going off and would give you a couple minutes to get ready to disable the alarm as quickly as possible.
