XIAO ESP32C3 - Power consumption decrease?

Hi,
is it possible to decrease the speed (CPU clock) of the ESP32C3?
The reason is that it draws 80mA from the LiION battery and quite hot.
I use BLE, but I suppose it shouldn’t eat that much CPU power (on the other side a JDY-23 works with 1mA)
Thanks Szabolcs
