Consider disabling BT

[mhschmall]

This project doesnt use BT for anything, why not turn it off? Just slip btStop() in the setup() section after ui_init(). Disabling the BT radio decreases power draw and I use this in practically all my esp32 projects.

well that really good to know.... I kind of just imagined it wouldn't come on if I didn't call it. That's huge haha. I am adding it now, I will let you know how it goes!

Its my understanding that its all turned on and ready to go in case you want to use it. In the low power game, its all about turning things off. The other aspect is that power consumption == heat, and these boards get toasty under load.

Yes! just had to switch glues as the screen fell off my test unit with the factory glue after running a 4 hours under load! Excited to see the power performance with Bluetooth off.
