https://community.sony.dk/t5/pcs-accessories/vaio-duo-13-battery-drain-on-wifi/m-p/1454876#M132688 <P>I have a Vaio Duo 13 (SVD1322C5E) for about 3 weeks with windows 8.1 preinstalled. I am having problems with battery drain in sleep mode and exessive battery usasge with Wifi on. For example, when I put the Duo 13 into ariplane mode before sleeping I get 1% loss in 6 hours. When in sleep mode and Wifi on I can lose between 2-4% an hour. This is not good when it is supposed to lose only 5% in 16hours with connected standby.</P><P>&nbsp;</P><P>Again, I get significantly more battery drain when working with the Wifi on. For example, in ariplane mode I would get 11 to 12 hours (using photoshop and Artrage). With same type of activity with Wifi on I &nbsp;only get 6-7 hours.</P><P>&nbsp;</P><P>What might be causing this?</P><P>&nbsp;</P> Sat, 14 Dec 2013 18:36:38 GMT iacton 2013-12-14T18:36:38Z https://community.sony.dk/t5/pcs-accessories/vaio-duo-13-battery-drain-on-wifi/m-p/1454876#M132688 <P>I have a Vaio Duo 13 (SVD1322C5E) for about 3 weeks with windows 8.1 preinstalled.
