Was that for the Wireless Stick or the CubeCell?  
The CubeCell [HTCC-AB01 should be able to get (much) lower](https://www.thethingsnetwork.org/forum/t/heltec-cubecell-part-1/30684/93) than 40 uA.

If you don’t need WiFi and Bluetooth you should be able to clock the ESP32 even lower, down to 10 MHz. See: [ESP32 power consumption at different CPU speeds](https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-3/18436/298)
