# Settings for battery and heavy mail use

To save battery, set Background sync to Auto-sync, poll less often such as every 6 hours, poll only 1st Class folders, keep fewer messages and turn on Quiet Time. For a busy mailbox, keep Background sync on Always, push the Inbox, poll every 15 minutes and keep more messages.

## How to settings for battery and heavy mail use

1. Pick the column below that matches your need.
2. Open **Settings** and apply each setting in **Network** and **Fetching mail**.
3. Check after a day that mail still arrives when you expect it.
