I did a hard reset after the latest 8.1 update and my battery life is amazing. I haven't charged my Lumia 928 since 9pm last Sunday night and I still have 30% remaining. I have all notifications on with banners, apps running in back ground and used it heavily.
With the easy reset and restore including your start screen, so easy and was a breath of fresh air for my phone.
