How do I calculate battery life of Arduino and XBee project? Here's my information:
- Battery's voltage: 3.6, capacity: 780 mAH
- Current draw of Arduino + XBee when sleeping = 28,5 mA
- Current draw of Arduino + XBee when wake up + transmitting data = 66,6 mA
- I have sleep cycle 7.5 seconds, so every 7.5 seconds will wake and polling data for 100 milliseconds
How can I predict my battery's life?
