I don't have a TP but I can tell you what I've used with my Pre. I have my hotmail set to check for new messages every 10 mins and yahoo and gmail every hour. I have used my Pre all day with several phone calls and browsing the web without having to charge it on a number of occasions, especially on weekends. Of course I do turn off bluetooth when I don't need it. There are times though that I will watch a DVD or listen to Pandora and of course that will drain the battery much quicker.
