How much battery life in Samsung Galaxy S4 and is there a T-mobile lollipop upgrade?

[Daniel Bennion]

I am getting a Samsung galaxy s4 and I was wondering, how much battery life do you get in one? like in hours of heavy usage and standby?

and while I'm at it, it is a T-mobile s4 and it says it will come as android jellybean, and I was wondering, I know T-mobile has a kKtKat upgrade, but is there a lollipop upgrade? If not I can take my phone to Best Buy and have them upgrade it, but I was wondering if there is one?

Hi, did you end up getting the s4? how are you liking it?

Yes I got my s4. I love it. I just got one question. How do I make it show notification previews on the lock screen? It is a kitkat currently. It does show text messages and emails on the lock screen. but I want it to show everything else. (Kindle notifications, google hangouts stuff, etc) so how do I do that?
