Hi guys. So I got the 8.1 update last night and I like some of the changes. But I noticed today that my battery life was horrible. I had my phone e plugged in, in my car since I was using GPS. So it was 100% at around 3pm and at 10:20pm I was at 19% before plugging my phone in and I didn't do much at all with my phone today. A little bit of web browsing but that's it really. I've had much more intensive days with much better battery life. Did they change something with 8.1 that I have to tweak settings to save on battery life?
