I also have to admit that first couple of days battery life was meh (maybe because I was playing with it all the time) but after almost a week, the battery life has improved a lot and very happy with it overall.
I've read that Samsung phones "learn" from your usage patterns over the first week or so, and then adjust accordingly, which then improves battery life after that first week. Sounds a little iffy, but maybe there's something in it.
