    My original iPhone over the past few weeks has been draining it's battery randomly. It usually does it overnight, but it will have normal battery usage for a few days, then one morning i'll wake up and it will have used 50% and will be off. I turn it on to find the red bar for battery, and have to immediately charge it. I then start receiving texts and missed calls. Anyone know of a solution to this?

    My brother's 2G seemed to get back to being OK after he restored and upgraded firmware.
