Replying to @josecastillo

this is something I discovered when feeding different input voltages to the Open Book with a Nordic power profiler. I was surprised to find that at 3 volts I was drawing less power than I was at 3.7 volts. Dug up the data sheet, and I found my answer why. https://www.richtek.com/assets/product_file/RT6150A=RT6150B/DS6150AB-05.pdf
