What should be nominal deep sleep current consumption with touch pin enabled

[mega128]

Hi,

I am using ESP32-S3-WROOM-1 module on a minimal custom circuit board with 3v direct connection to a lithium battery.
With one touch pin enabled, the deep sleep measured is around 100uA. Is that normal? What else should I do minimize power consumption further?

Basically, I want it to monitor touch pin while in deep sleep with lowest possible power consumption notwithstanding clock speed etc.

Thanks,
Jay

This certainly sounds like a reasonable value for the current going through a 50K internal pullup resistor (100uA @ 3V3 => 33K Ohms). Have you tried reducing the sensor voltage (https://docs.espressif.com/projects/esp ... asurements)?
