Abstract
A method for estimating a remaining battery life of a non-rechargeable battery of an Internet of Things (IoT) device. The method includes determining an amount of battery capacity used by the IoT device while the IoT device was operating in an active mode, an amount of battery capacity used by the IoT device while the IoT device was operating in a sleep mode, and an amount of self-discharge of the non-rechargeable battery while the IoT was deployed based on temperatures of environments in which the IoT device was located. The method further includes determining an estimated remaining battery life of the non-rechargeable battery based on an initial capacity of the non-rechargeable battery, the amounts of battery capacity used by the IoT device while the IoT device was operating in the active mode and the sleep mode, and the amount of self-discharge of the non-rechargeable battery while the IT was deployed.
