I have noticed a problem...I think it's a problem... I use my phone a lot. Almost all day. I had the stock battery with juice defender and screen turned down extremely low and I was pligged into outlet. Phone would not stay charged. So I ordered a 3500 battery to help me with this problem. My question is...If I am plugged into the wall shouldn't that keep the phone going? I have had phone die on me quite a few times now.
