It will limit the background activity of apps when your phone is not in use.</P> <P>You can find this in Settings &gt; Battery &gt; 3 dots &gt; Battery Optimisation.&nbsp;</P> <P>The battery drain is likely due to the updates you were performing.</P> Thu, 15 Sep 2016 04:01:36 GMT https://community.sony.rs/t5/xperia-archive/app-optimization/m-p/3496245#M542517 CameronT 2016-09-15T04:01:36Z
