To ensure transparency and accuracy in our estimations, our software adopts a worst-case scenario approach in two key ways. Firstly, in our calculations, we deliberately degrade the battery capacity indicated by the manufacturer. This ensures that the estimated battery life is not based on the assumption of a full battery, providing a more conservative and realistic projection. Furthermore, we factor in the maximum allowed duration for each GPS position in our battery life calculator, even though this scenario is unlikely to occur in real-world usage. By intentionally under promising and overdelivering, we prioritize customer satisfaction and guarantee that users will not encounter disappointments such as unexpectedly shortened battery life after setup.
