They become active when the user installs and inactive when they are uninstalled. Inbetween, they are not limited in runtime. That said, the current programming is that when receiving a block, it stays connected for at least ~2 more minutes. This generally allows the chain to catch up while at the same time avoiding endless battery drain because something gets stuck. Upon sending or receiving of a transaction, it stays connected for at least ~8 more minutes, because it is likely the wallet will see more activity. Additionally, on the send and request coins screens and the network monitor it stays connected for as long as the screen is on and the app in the foreground (= resumed state).
