battery life using deep sleep

Hi,
I have been working on a similar project using the esp32 w/mqtt and deep sleep mode. I also am using the capacitive moisture sensors that utilize the 555 timer circuits, and a lm35 temp sensor. I also use a voltage divider to monitor the battery level. I sleep for 15 minutes, then wake up, connect to wifi, take the readings and send the mqtt messages to the three topics then go back to sleep. My Raspberry Pi is running the mqtt server along with home assistant and nodered. All of it works perfectly except for the battery life. I was testing it using AA batteries and I can not get decent battery life. It will basically die in about 3 to 4 days. I was wondering what kind of battery life is your project getting? I also should mention that I am using the hiletgo ESP-Wroom esp 32 board. JUst the board itself in sleep mode seems to be using around 12ma which does not seem right to be in deep sleep.
