A case for lease-based, utilitarian resource management on mobile devices

If an app is making good, legitimate use of the resource then the lease will be transparently extended. If an app has been using resources efficiently, the lease manager increases the lease term, reverting back to the 5-second lease on any sign of misbehaviour. Testing with apps that legitimately make heavy use of resources (RunKeeper, Spotify, and Haven), LeaseOS renews leases without any interruption, whereas under the pure throttling scheme all three apps experienced some disruption.
