@jlcrawf I had thought about leaving my normal phone, a Pixel 6, here at home when I go on vacation, but the battery seems to go quickly, it's slow and runs at like 5fps especially when scrolling or trying to play a video, and it doesn't support RCS so I'd be unavailable to a few people for the week (and that's not what I want to do).
For regular usage, there's no native Duolingo app, for instance, and the web UI is uncomfortable to use on it. There's no mobile banking, so it would all have to be done by web too. And both Epiphany and Firefox are a pain in the ass to try to use on such a small screen, with touch; scrolling and videos are the biggest pain points here, but Firefox being weird with its popups is also a big contributor.
It doesn't take a lot to make it warm up, either. Using any browser for more than ten minutes does the trick; the LED starts blinking a few minutes after that. And of course that's necessary to do anything at all with it; half of the apps that are supposed to work with it don't, often because of popups that stretch off screen or don't close correctly.
Mostly my complaints boil down to hardware and software mismatch (you're trying to run desktop software on mobile hardware; that's never worked well) and lack of app or feature availability.
