Sony said that it is reinstituting one of its signature features back to the Xperia line. The Stamina mode is a battery saving feature that Sony promised will be soon rolled out to devices that are running the Marshmallow operating system. The company has confirmed the news but did not provide a specific timeline as to when exactly it plans to release the feature.

The Stamina mode feature will be rolled out to a handful of Sony smartphone. So far, Sony has only the Xperia Z5, Xperia Z4 and Xperia Z3+ support the feature. Sony added that support for Xperia Z2, Xperia Z3 and Xperia Z3 Compact will arrive this April, according to Android Community.

With the Stamina mode turned on, Sony claims that its devices can run for two-days straight on a single charge. The mode is able to save precious battery life by stopping all unauthorized background applications. However, the feature was dropped when Sony upgraded its devices to Android Marshmallow, a move that shocked most of its users.

Reports claim that the reason why Stamina mode was dropped is because of Google Doze, a feature that comes integrated with Android Marshmallow. While both Doze and Stamina offers the same kind of function, the latter is deemed more effective based on user reactions when it was dropped.

In a statement posted on the official Xperia Blog, Sony wrote, "Great news. One of the most requested features is coming back to your Xperia running Marshmallow. Stamina mode. We don't have a release schedule yet, but the feature will be definitely available for members of the Xperia Beta Program in the near future."

The full coverage of the feature is still a mystery. However, some tech experts said that the Sony Stamina should be able to work hand in hand with Google Doze in order to increase battery life. On the other hand, some are quite skeptical whether Stamina will work since Google have always made it clear that it will not allow OEMs to interfere with the battery saving features of the Android operating system.
