I am considering using the RTC in the i.mx6 but have two concerns about the battery life.
1. The data sheet mentions the current consumption from VDD_SNVS could be 250uA.
I have also read the minimum battery voltage is 2.8V so from a 3.3V, 5.5mAH rechargeable battery this would not last very long.
Is this correct?
2. In our application the power could be removed before placing the imx into a low power state - could this result in even higher current draw from the battery.
Could this be the case?
