I've been runnnng GrapheneOS with charge capped at 80%. Phone has not emulated thermite.
I haven't found any discussion about the battery issues at GrapheneOS yet.
I have kinda bad battery issues on graphene and have been having it even on my old pixel 5 (currently on pixel 8a).
Could it be because I use google play services? Maybe I'll get a huge decrease in battery consumption if I cut this off. But I do need it for maps and stuff
Meaning you charge till 80% full, or at 80% max charging speed? just curious.
80% full. It drastically helps extend battery life
Yep. It's the capacity.
Anyone can cap the charging speed by using a garbage $2 700mA charger from 2008.
Is this done manually , or there’s a system thing for it ?
In GrapheneOS, Settings -> Battery -> Charging Optimization.
Many phones support it. My old mid range Samsung galaxy phone from 2020 had it, as does my Pixel 9a.
