Power consumption within connection

That will depend on the connection interval and advertising interval, and all the other settings you can configure. I am not surprised that for shorter intervals that staying in a connection use less energy, but for longer intervals then advertising use less energy.

But what value of connection interval I have to set. When I will connect once, I will not disconnect a long time (maybe 30 days)... It looks like that advertising mode consume more power than connection mode. Is it true ?

There is a detailed online power profiler for nRF52-series:

(direct link: https://devzone.nordicsemi.com/nordic/power/w/opp/2/online-power-profiler-for-ble)

We don't have any similar for the nRF51-series, but I expect the numbers to be about 50-100% higher on average. I could find someone have tried to make something for the nRF51-series here on their own:
