Hello Luca,

this is a weird one. unfortunately, xiaomi likes to come up with non-standard things. and they introduces an additional property for a battery[0] in their downstream driver. I tried to apply a patch that is super minimal in terms of LOC.

right now this is just 1 patch not splitted into several different pieces because I wanted to hear your opinion on other potential ways to handle this particular quirk.

PS I also added you to my fork, so you should be able to force-push to branches in my repo
PPS w/o this patch the battery behaves super weird and gnome-mobile just freezes/stucks

Hi, could you please send your patch upstream to the mailing lists? I would like to know what the maintainers will say about this approach or if they have an alternative proposal.
