Hello, I've recently purchased a vaio duo 13. I used powercfg in cmd to estimate battery wear and it found it was 0%. I closed sim detection,I turned off bluetooth,I set the sound at 20% and the brightness at ~20%. I also set the tablet to silent mode ( no fan) in order to increase battery life. I have opened the following programs: firefox (or chrome),skype and onenote (or matlab instead of one note). I get around 7 hours of constant battery life. Is there any way to escape the 7 hours limit and achieve 10 hours of constant use?I think I have to do something really simple ( or perhaps I don't).Do I have to turn off wifi and not use internet to achieve close to 10 hours? Thanks for a lot your time. Edit: I am mostly using the tablet in laptop mode with the keyboard exposed.I also deactivated the backlight option because I thought the light was draining the battery fast.
