Startup and WiFi connection are more fast in ESP8266 than ESP32-C3

[agi63_ita]

Hi all,
I'm working with ESP32-C3 with uart AT-commands mode. I use it to connect at WiFi AP as a client.
If I have WiFi network configured, and AUTOCONN enabled, when power-up modem sequence is:

boot --> "ready"

and than URC:

WIFI CONNECT
WIFI GOT IP

Problem is the delay from "ready" to WIFI CONNECT:

in the ESP8266 about 1s
in the ESP32-C3 about 3s

What could be the problem?
I noticed that (in the ESP8266) going from version 2.1.0.0 to 2.2.1.0 the same thing happens!
My device is battery powered and and more time WiFi ON means more consumption!

A big thank you to anyone who can help me, otherwise I will continue to use ESP8266.

bye
Andrea
