Windows 10 Destroyed my Battery Life

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?

Welcome to tenForums!

To investigate your battery usage please have a look at the following tutorial and work through the steps:

Then you should also run the power efficiency report:

Looking through these reports will help you identify at what times in the day the battery was drained the most, hopefully you can relate it to what you were doing. You may also find there are a number of settings you can tweak to improve battery performance based on the analysis.
