What is mail days to sync on my iphone

"Mail Days to Sync" is a setting on your iPhone that controls how often your email account synchronizes with your iPhone. Here's what it does:

When you set a specific number of "Mail Days to Sync" on your iPhone, it determines how many days' worth of email messages are downloaded from your email account to your iPhone. This setting helps manage your email storage on your iPhone and can also improve performance by reducing the amount of data that needs to be synced.

Here's how it works:

To change the "Mail Days to Sync" setting on your iPhone:

  1. Go to Settings > Mail, Contacts, Calendars.
  2. Tap on your email account.
  3. Scroll down to the "Account" section.
  4. Tap on "Mail Days to Sync".
  5. Choose the number of days you want to sync (e.g., 3, 7, or 14).

Keep in mind that this setting only applies to the email account you're currently viewing. If you have multiple email accounts set up on your iPhone, you'll need to adjust the "Mail Days to Sync" setting for each account separately.
