With the discharge of iOS 13, Apple launched a brand new characteristic referred to as “push” for the Mail app when used with Gmail accounts. This characteristic permits customers to obtain near-instant notifications for brand new emails, even when the Mail app is closed or within the background.
Previous to iOS 13, Gmail customers on iOS units needed to depend on the Mail app’s “fetch” system to verify for brand new emails. This method would periodically verify for brand new mail at set intervals, equivalent to each 15 or half-hour. In consequence, there could possibly be a delay of a number of minutes earlier than customers have been notified of latest emails.
