Based on the current HW design and configuration (processor, display, GPS, battery) the battery life theoretical limit is close to 24 hrs.
The power optimization is based on 'dynamic frequency control'. If high performance is needed for calculations and graphics the processor runs up to 500 MHz. When only data recording and minimal visual updates are needed the processor runs as low as 5 MHz. For idle time between receptions of GPS data and sensor data the processor can be put in to a sleep mode where only the real time clock is running at a modest 32KHz.
We will enhance the power optimization schemes over time through our SW updates. There is no need for any hardware updates, therefore the current Leikr watches should be able to reach the target battery
The Leikr watch has now a battery life of approximately 5 hours.
