Reason for posting this question - my laptop battery died and it turns out the bios gets reset every time I turn it on now.
Made me think of the old phones I have which cannot be repurposed without getting new batteries…
I guess mandating replaceable batteries is enough but IMHO it should go further
I did not know about battery idle mode, thanks. Would those phones work with the battery removed somehow? Possibly not.
I found a hack online for one phone with a removable battery, involving soldering a capacitor or something. Will test when I have time
