[Android: ] Best way of conserving battery?

I find that Syncthing on Android ends up using much more power than any of my other apps. What is the best way of optimising the lowest power use of Syncthing on Android?

I’m using Powernap, and I have Greenify available, as well as Tasker. I don’t mind if the synchronisation is only every few hours or whatever. Advice?

You could use Tasker to run the app only at certain times (wiki link). Or just set it to sync only when charging.
