Dave Bird's Tech Note 097 compares ESP32 boards on deep sleep current and is cited when choosing a board for battery power or bypassing its regulator.
Pointed to for measured ESP32 sleep currents, especially the finding that dev boards draw far more than bare modules, which matters for battery projects.
Andreas Spiess works through powering an ESP8266 from a battery, covering the calculations involved, oscilloscope traces and adding a capacitor across the supply pins.
A generally well-regarded LED strip tutorial for newcomers, also valued for showing how to measure real power draw with a multimeter.
