Yes it does (for sensible). But anyway, are you telling (confirming? to us) that anyone can boot (up to the title of this thread) Librem 5 Evergreen without inserted and healthy (charged over 0%) BPP-L503 battery? If so that would be nice feature to count on, when necessary, like here in this thread.
@irvinewade, I guess you don’t mind to
sudo poweroff your Linux phone (that isn’t called PinePhone), take battery out, connect it to original power supply (charger that provides 0.45A, might be the case, only to it) and let it boot PureOS (Mobian, pmOS, SMXO), if this (without battery inserted/connected) works for you. And sorry if I’m reading your post wrongly, but still your post was somehow inspirational to me, thanks therefore!
Yet, this is (still is) important note from @libwood (that I liked and didn’t comment):
Further, as @amosbatto already recommended here, within this thread, those eight steps are very basic (to boot) requirements indeed, I have no doubt. @coconutcream, after following those eight steps, please, by using original Librem 5 power supply, press with your finger and hold power on button continuously for around 10 seconds (few more seconds might be better, red LED light stays constantly on, as charging current will change/decrease few %, irrelevant how much here, as I’m not an expert, but probably related to battery charging stage/status like almost empty or almost full, necessary electric current to charge it will vary anyhow) as just briefly pressing power button for as many as 50 times won’t wake up your Linux smartphone, I guess. Release it (same power button) for around one second and press power button briefly (twice, three times might be necessary as well) again, you should get green LED light at first, meaning your Librem 5 should boot now, I hope (if original battery still usable). Anyway please let me know if you tried this approach (as I just made this guide up for you, nothing serious from my side, just based on my intention to help, unofficially help).
