I don't have LTE in my area yet, so I'm just on AT&T 4G. I've done better than this, but this is typical for me, partly because of work though. I can't have a cell at work, so it sat 12 hours idle. Still, that's 26 hours being active, about 2-3 hours screen time. I'm not a heavy phone user, so I can stretch the battery a bit more than some. I think the longest I've gone was 1d 18h, somewhere around there.
