My battery is behaving very strange after updating to 2.1. So far since updating 2.1 this is what has happened: 1st time - I charged to 100% left it on standby overnight, all apps completely closed. I didn't use it until the next evening when I tried to turn it on it didn't respond. So I held down the power button and it gave me the no battery icon. I checked usage and it was way up around with the standby time, which I thought was strange because I definitely hadn't used it for that long. I didn't bother to screenshot it; I just dismissed it as a freak thing and I did a full charge (thus a cycle which should calibrate battery indicator). 2nd time - I used the iPhone the evening after I did the full cycle, and when I went to bed it had about half a charge and 2h. 21m. usage (see 1st pic). I wake up but I didn't use it until a slightly after 4:00 PM. So again I try to turn it on but it won't respond, I hold down the power button and once again I see the no battery icon. I plug the iPhone in the charger and immediately after it turned on I took a screenshot of the Usage stats (see 2nd pic) and as you can see it has 18h. 35m. of usage. So I'm thinking something is running in the background, but I don't know what, I even did a hard reset after my full cycle to try and eliminate any background apps (or whatever it may be). I know people are having cases of background processes running down their battery, but this has happened twice in a row, with a hard reset in between and a full cycle to make sure my indicator was accurate. Tips, suggestions, conclusions? What do you think? snverhallen PS. If your wondering why in the 2nd pic I have no Carrier that is because I was trying to import SIM contacts from another SIM that doesn't work here hence no Carrier name.
