Mail App Push or Fetch

[madrich]

What is the best Maill App setting to conserve the battery, Push, Fetch, or both?

For battery, Fetch will be give a little more battery. But I don't think you will notice that much. I can see the app "Amphetamine" has used more processor time than Mail. And I have Push iCloud on my MacBook Air.
