OLED runtime test in progress. It's definitely going to have a shorter runtime than the eInk display did. Currently at 3.84v after 23.75 hours. The eInk run took 38.6 hours to drop from 4.2v to 3.84v. If the ratios hold this means 51.68 hours to stop of serial data and 49.8 hours to stop of meaningful battery voltage readings. We will see how accurate that prediction is.
