In my experience it strongly depends on the organizers. The latest pro-palestine rally i attended was organized by some leftist organizations in coalition with local palestinians and that rally worked out very well. Some conspiracy nuts with signs how Jews rule the world were told to fuck off by some Antifa guys and everything else went very well. Also no national flags besides palestinian ones were allowed, i appreciated that a lot.

I mean, I use a fairphone (with removable battery) and in a normal day it can go a whole day without going below 20%. And even if I don’t comsider ot too much of a hassle bringing an external battery for recharge with me when I know I’m gonna use it a lot or will not have time to recharge during the night.
