To answer my own question. I found when compiling my project there was an option to slow to 1/2 cpu speed and more. Normal is 160mhz {wifi) there was another option 80mhz (wifi). Under normal speed 160 it used 36ma but when recompiled to 80mhz it now uses 27-28 ma. I don’t need the faster speed and saves about 27% power on the battery.
You will find this option tools > CPU frequency.
I noticed there was an option to lower flash memory from 80mhz to 40mhz but it did not have any affect on power.
Hope this helps someone.
