According to @Ricciolo1, a well-known leakster, Sony plans to update its Xperia Z5 lineup to Android 6.0 Marshmallow in January with older models to receive the same treatment shortly after.
Marshmallow offers a bunch of improvements, optimizations and features that’d be welcome on any smartphone. Battery life improvements and performance boosts are the most noticeable changes to the software.
Whether or not Sony will decide to update the Xperia Z this time around is unknown but it sure would be awesome to see Marshmallow running on a phone from early 2013.
