about minimal power usage

[tuanlinh9x]

Hi, I have a few questions about how to minimalize the power usage of the ESP32

Right now I'm using ESP32 for BLE application. The ESP will advertise for about 200ms then go to deep sleep for 10 seconds. I managed to put the ESP to deep sleep with minimal power usage but when I wake up from the deep sleep, I found out that it requires at least 30ms to boot(I disabled logging and ROM log) then init the "NVS" and "BLE" takes a total of 400ms where BLE init takes 100ms. Is there anyway I can reduce those 3 number:
- boot time
- NVS init
- BLE init

Thank you
