I'm usually not a conspiracy theorist guy, but really makes me wonder if this is planned to get users of old models to upgrade. and the SE has A9 chip, which is same chip as the '6' line. Now I realize the 5s is old tech, but so what, this shouldn't happen.

This behavior is happening on a 5s and a a new SE. Scrambling to try to downgrade back to 11.4 or 11.3.x but worried I might brick it. By the time I arrived at destination, using GPS/Maps had drained battery to 15% IN THIRTY MINUTES. Drive took maybe 30 minutes, did not have it plugged in, started at 95%. Once time in the car, I had to use Maps to get somewhere.

I had no battery issues with 11.4, after upgrading to 11.4.1, my battery will drain from 100% to below 30% over the course of 4 hours doing nothing but sitting on the desk, no phone calls, no browsing. For some it has for me the OPPOSITE HAS HAPPENED. Many folks reported severe battery drain with 11.4, which the new release 11.4.1 was supposed to address.
