Ever since I installed SBSettings and put in the numerical value of my battery life, I've been hesitant to use any apps or surf the web on it. I could surf the web for maybe five minutes and I can see as much as ten percent of my battery dropped. 5-6 comes back afterwards, but that seems like a huge fall regardless. Same thing for any apps. It' strange. Is it supposed to be this way? Or is my iTouch faulty with its battery?
