Battery life remains a critical constraint for continuous stress monitoring in real-life settings, as the wearable devices used for physiological data acquisition typically operate for only a few hours on a single charge. Addressing power consumption is therefore essential for enabling all-day monitoring outside controlled laboratory conditions.

The battery life of smartwatches and fitness trackers vary greatly depending on the features and functionality available on-board the wearable. The Apple Watch Series 5, which is more of a lifestyle and fitness tracker, can run for a period of up to 18 hours whereas the Fitbit Charge 3 fitness tracker can go for up to 7 days on a single charge. Continuous activity and heart rate monitoring speed up the depletion of the battery of most wearables. Gathering and processing of simultaneous sensor data can further increase the power consumption of the devices.
