I plugged in an old iPhone SE into the Lightning port on a nice speaker and locked the screen to Spotify -- with auto-brightness it worked fantastically.

Until it also turned into a spicy pillow after about a year and a half.

Really wish there were some kind of system preference to run off wired power only and just not charge/discharge the battery at all.

Some older iPhones can be powered by a $30 "battery simulator" used by repair shops, https://youtube.com/watch?v=jTtGwKS7S0c &

I've tried but I don't get the spicy pillow reference. Did it catch fire? Or the screen die?

I believe it's a reference to the look of a failed LiPo battery: it puffs up and looks like a pillow, but if you puncture it fire spews forth.

Reddit first came up with the phrase "spicy pillow" to describe that combination.
