Building energy consumption models based on smartphone user’s usage patterns

WeTrace: A privacy-preserving tracing approach

“…Therefore, it is one of the key aspects of COVID-19 tracing apps. As the energy consumption depends on the device and users' usage characteristics [42], it is not a trivial task to precisely determine always energy consumption. However, BLE was specifically designed for lower power consumption, allowing beacon devices advertising their presence every 100 ms using a 1,000 mAh battery to last for up to 4.5 months [43].…”
