Bangle.js power-saving feature proposal

It could be, but in some ways an app is easier - it's easy for people to find by searching rather than being buried deep in settings. If you want to try it out for now, just install the Custom Boot Code app and paste this in:

(buzz => {
  Bangle.buzz = (a,b) => (Bangle.dbg().pollInterval < 500) ? buzz(a,b) : Promise.resolve();
})(Bangle.buzz);
