imx6 RTC Current consumption

Hi    

 

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?

 

Thanks

Peter
