Other good sources: oom-priority tag wiki (unfortunately, we've got no "oom killer" tag – you know, the process coming to action when the system is "Out Of Memory"). And "available" is relative: RAM used by caches becomes available when flushing them, and RAM used by apps after killing them ;) | |

| Aug 14, 2017 at 12:15 | comment | added | Izzy | "Free RAM is always important": On Linux systems (and also on Android), it's rather free RAM is wasted RAM – which is why RAM not claimed by apps/processes is used e.g. for file-system caching, to speed up things (if later some process needs more RAM, those caches are what's dropped first). Thus, "Your phone should never have its RAM full" is not quite correct either, as "full" RAM often means efficient use. For details, see Are there guidelines on how much free RAM a phone should have? – and of course our ram tag-wiki :) | |
