Reapeating the same question:
Why ESP-32 consumes 120 mA average? It should consume 80 mA as per documentation. I have checked several development boards, all consume more than promised. All ESP-32 are quite warm.

Re: The reception performance of WiFi?
I guess you use ESP-WROOM-32 module. Try ESP-WROVER-32 module with an external antenna.
I've got an impression that ESP-WROOM-32 modules have problems with antenna matching.

Re: Bad usb cable horror - please add warning to docs & getting & started
ESP-32 consumes a lot of current while transmitting. I saw spikes of 0.7A with duration of 0.5 ms. If you have USB cable with resistance of about 2 Ohm, then those spikes might cause reset. Use a 1000 uF capacitor across +3.3V rail. After that it should work with any USB cable. I saw those 0.7A spik...

Re: ESP-WROOM-32 specifications
There are several sketches named WiFiScan: for WiFi shield, for ESP8266 and for ESP32. I should upload the sketch for ESP32.after uploading sketch in serial monitor I see ascii character ??

ESP-WROOM-32 specifications
Hi, When I compare ESP-WROOM-32 datasheet with ESP-WROOM-02 datasheet, the specs looks almost identical: average current consumption 80 mA, sensitivity -91dBm @ 11 Mbps. But when I test real modules, their performance differs drastically. Running Arduino WiFiScan sketch on ESP-WROOM-32 and on ESP-12...

Re: ESP32 Power consumption considerations
Hi, Using an oscilloscope I have measured current consumption of DOIT ESP32 DevKit with ESP-WROOM-32 module running Arduino WiFiScan demo sketch. While executing WiFi.scanNetworks() function very first time, module consumes average current of 0.5A for 10 ms with four peaks of approx. 0.7A during tha...
