I, like many others, had Windows 10 installed automatically when I wasn't home. I'm not necessarily opposed to this except that it has OBLITERATED my battery life. As an ultrabook user, I primarily own my Lenovo T431s because it can last me days at a time, or at least one day of heavy usage (8+ hours). However, I noticed that since Windows 10 was introduced my usage time is not nearly the same. Just listening to music will result in 1-2 hours at best, even with dim settings. I have to count the minutes every time I take my laptop off the charger.
I've read that MS is working on optimizing performance, but this is beyond optimization -- something must be actively draining the machine. Any thoughts?
