10 Disable or Limit Email Fetch Frequency
When you add email accounts to the Mail app, you can adjust how often your device checks for new emails. To save battery, you’d be better off adjusting the settings such that new emails are fetched less frequently (e.g. every half an hour). If you don’t require this feature at all, you can disable it completely.
- Go to Settings.
- Tap Accounts & Passwords.
- Tap Fetch New Data.
- Here you can lengthen the fetch frequency, or disable it altogether by turning off the toggle next to Push.
