Moore's Law has not been improving batteries, which is the real problem. Mobile P2P nodes need to be awake most/all the time, which is a real battery killer. Modern devices have improved battery life by being asleep almost all the time.

Depends on what those p2p nodes are doing. We do p2p on mobile but it's to allow the mobile device to act as a client to access an IoT device, not to force the mobile device to act as a CDN node. Spotify was doing the latter, which is more problematic.

Moore's Law eventually will matter, since faster and more efficient chips equal the ability to do more with lower power consumption. Batteries aren't getting better fast enough, but power consumption per fixed unit of compute is falling like a rock. As a result "effective battery life" for a given fixed workload is subject to Moore's Law.
