To simplify the calculation, we can:

Combine built-in sensor and E1 sampling energy together to 870ms@2ma

Combine two RX windows together.
There is a power consumption tool for easy analyze. And below is the analyze result.
Ignore the 11 year, because the battery has a max 2% discharge per year.
