TTGO LoRa v1.0 high deep sleep current consumption #28

Dear TTGO-Team,

I have purchased the v1.0 TTGO ESP32 & SX1276 version here: https://www.banggood.com/2Pcs-LILYGO-TTGO-ESP32-SX1276-LoRa-868MHz-bluetooth-WI-FI-Lora-Internet-Antenna-Development-Board-p-1295045.html?cur_warehouse=CN&rmmds=search

The deep sleep current consumption is 12mA when powered over battery and 14mA when powering the 3.3V rail with a benchtop supply.

I'm quite sure I've done nothing wrong.

Can you recommend how to lower the power consumption? Are there new boards with better efficiency? Best and thank you!

Same problem here.. I bought 2 boards. Current consumption in deep sleep mode is 11-12mA.
