ESP32 has lower power consumption than ESP8266. Its current consumption is 10 micro ampere in deep sleep.
For further info regarding the low power modes of ESP32, you can see the following articles: https://www.theengineeringprojects.com/ ... modes.html

I bought two ESP32 WROOM Devkit v1 to experiment with the "big brother" of ESP8266 but unfortunately the power consumption during deep sleep is even greater than with ESP8266 (about 11 mA vs 9 mA).
I tried also to take the power LED off from the ESP32 but consumption decreased by just 2 mA then at the same level of the "little" brother.
Probably the solution is to go with a raw module (as btidey wrote)...
