I think it costs electricity to flip bits, but unless things are moving, there’s not much going on. If the app isn’t actively being used, I was wondewring why it couldn’t just get frozen in carbonite and dumped into storage until the user needed it again.
Comment on Why doesn't Android save app memory into storage instead of killing the process in RAM?

Indeed, RAM is a memory latch by use of a capacitor. And on an interval it replenishes the charge of this capacitor . Thus when there is no power it will lose all its data.
These days it is possible (and Android has/does this) to just write old programs from RAM memory to the SSD, this is a slow process back and forth. But it saves RAM space and power.
