Power Consumption Example:

300mA battery= 300 000uA

300000uH/1,4uA=214285 Hours/24 hours= 8928 Days Stand By Mode

300000uH/590uh=508 Hours/24 hours=21 Days if Device Running all the time.

Real Time Example: Average Standby 90% day, Running mode 10%, SMS Sent once per week

about 90 days in one Full charge with 300mAh Battery.
