Battery sizing using SNVS_LP

Document Number: AN4509 Rev. 0, 09/2012 "i.MX 6Dual/6Quad Power Consumption Measurement" App Note states "The power consumption of SNVS is comparatively negligible except in Deep Sleep Mode” and doesn’t go into any more details


“Negligible” is a fuzzy word for something that is always on when coin cell is attached (SNVS_LP.) 


There must be some current which will help to size the battery as how long the need to have backup.


Are there any characterization results?


Thanks, in advance,
