Roughly speaking, GSM in power safe mode consumes 1.5mA. In active mode, current consumption may vary from 50-200mAh. There are also 2A spikes.
Additionally, MCU, LED and accelerometer should consume less than 5-10mAh.
Thus, we have nearly 10mAh consumption most of the time (not including active and high current modes). With 1000mAh battery, gTrack should work nearly 100 hours (4 days).
Actually we have only 2-3 days.
Need to investigate what draws most of the current and how to decrease consumption.
