man "YMMV" def applies here cuz I can push almost a day in half to two if used light to moderately but like some above posters I turn most things off of auto-sync set to manual and also lower my brightness/timeout/and use wifi as much as possible. I mostly use the web couple hours a day (YAY for the bigger screen as I have to use it for thechive sometimes

), snd a few txts a day maybe just as many phone calls, angry birds or games here or there.
For a smaller battery I think it still outperforms my old Captivate as it would sometimes die before leaving for work but I can see the Inspire battery as a problem for those "heavier" users.
