Something that seems to have been overlooked by me and most users of IoT devices with capacitive touch screens - sleeping the touch controller when the MCU goes to sleep 🤪. Your ESP32 + (xxx display) may mysteriously use an extra 2mA or so when you put it to sleep. I added preliminary support to my bb_captouch library to allow you to easily sleep and wake the touch controller to save power. If any of you can provide some feedback or testing, I would appreciate it:
