Actually that is not quite correct. See:

Hi.
I don’t have data about that.
But, Hibernation mode consumes less than deep sleep. See this table:

You can also take a look at the datasheet to compare power comsumption of different sleep modes:https://www.espressif.com/sites/default/files/documentation/esp32_datasheet_en.pdf
However, take into account that the values you’ll find are for the bare chip. When using a development board you’ll always have higher power consumption.

Thanks!
If the board is put to hibernation mode, can it be woken up by timer ?

Hi.
I don’t think so.
In hibernation mode, RTC is off.
