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.
