I just wonder, how does Otti Arc calculate battery lifetime (in years, months, days,…) in Battery Life Estimator tool? I’ve looked for tutorials on Google, found some equations, formulas,… but some current & time parameters caused different lifetime output than what Otti calculated!
Hi and welcome to the forum.
Otii Battery life estimator tool calculates the time by dividing the capacity with the average current consumption.
The average current consumption is calculated by
Otii Battery life estimator do not take into consideration, for example, battery self discharge or available battery capacity for your use case.
The available battery capacity for your use case can be found out using Otii Battery toolbox.
