pavlikai, I have free about 600 as a rule, but a bunch of processes are hanging in cache: Yandex Disc, browser, toys Cooked, WhatsApp, something else worst constantly, but it does not start, but simply unfolds, not spending a bunch of time and energy on Running while it is simply hanging there, the battery is not spent on them, so the volume of free RAM with 2 gigami on board nothing more than paranoia :)
shavilko, With an angelic language, you are certainly tagged :) In general, it is very problematic on this device with a working Internet work, and the more often you spend the programs from memory, the more charge you spend, because Android is designed in such a way that keeps the program in memory as times to save charge. Of course, there are programs referring to the charge on an ongoing basis and you can only kill them, and the rest will still start back for 10 minutes and wait for the RAM and will spend part of the charging.
