My current 3g I have had since November, it was a replacement so im assuming its a refurb. Over the past week or so my battery has been draining rather quickly, where ill put it in my pocket and a couple hours later check it and i've lost half on the indicator. I haven't changed any settings and ive actually killed off bluetooth and it still drains quickly. Before I call up and get an appointment, will Apple replace the battery of my phone since im still under warranty? Has anyone else experienced this or went through this with Apple??
