This is my first smartphone and have only had it for a few days. From the beginning I turned off locations, wifi, sync etc.. anything I would not normally use. Battery life was ehhh. Today, I turned off the 4G (very spotty where I am anyhow) and right now after a little over 10 hours unplugged I have 44% battery left.
I am a light user but before this I think I was getting around 12 hours or so out of a full battery.
Just wanted to share with you all.
