First i want to ask a question about the original battery that comes with the phone. So the first week or so i had this phone the battery life seemed decent, however over the last couple days my phone has been dying VERY fast, after charging 100%, not even using the phone at all, and with the mobile network disabled, over just 1 hour the phone died anywhere from 15-20% in battery left. That is way to much especially with 3/4g off and juice defender running. I have installed a bunch of games and apps since i got the phone so would that cause the battery to die that fast even if they cant access the network since the network is off? Secondly, i was looking at the extended batteries and was wondering and guess the answer is no?. But I will not be able to use my current cover that i have on my phone(body glove) am i correct?
