Google has launched version 3.0 of its Gmail app for iOS devices, bringing with it the ability to update users' inboxes in the background. However, some users have reported performance and battery issues since updating the application.
The update also supports multiple sign-ons, meaning once users have logged into one Google app on their Apple device, they are logged into all of them.
While the update does not bring about any major visual changes to the app, the ability to refresh email in the background is a key addition that has been present in the Gmail app for Android for several years.
The ability to sign in to multiple Gmail services at once is also a feature that has been available for Android for a long time, because users are required to have a Google account to perform many of Android's key functions such as downloading apps.
In order to use background email updates, users will have to turn it on via the app's settings as well as enabling notifications. Only users with devices running iOS 7 will be able to use the background update function.
Google software engineer Melissa Dominguez explained on the Google Official Enterprise Blog: "The app now fully supports background app refresh, which means your Gmail messages will be pre-fetched and synced so they're right there when you open the app – no more annoying pauses while you wait for your inbox to refresh."
Notably, the app's rating among users in the Apple's App Store has dropped, falling from four stars to three. Complaints from users include sluggish performance and increased battery drain as a result of the background refresh function.
"This update included background app refreshing and it killed my battery life very quickly," said one user.
The update comes less than a month after Google released its long-awaited Google Apps Admin app for iOS, much to the delight of system administrators.
