Yeah, what I meant is, it'd be useful to know the aver= age amount of time that the app was holding connections open for.

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 (=3D resumed state).
