Hi, I've had my iphone for a while now (firmware 1.1.1), and it used to go for up to 3 days (maybe more) with a full charge. For the past few days, I found myself charging it twice, and starting yesterday, three times a day. Very weird for an apple device, and definitely strange for a relatively new cell phone. My usage is very moderate. I rarely use it for other than phone calls. I keep it charging overnight, and within 6 hours of unplugging, the bar is red. What could be the problem? Could it be that I am outside of the US and the charging voltage is different? I find it highly unlikely, but have no idea what might be causing this. If the battery was defective, it would have shown early on. I deactivated anything that might be draining the battery, but the problem still persists. Any thoughts would be highly appreciative. thanks.
