Riddle me this Batman, So I'm on my 4th iPhone now. Started with the 3G and had them all except the 3GS. The one constant has been I'm lucky to get a full day of use of the battery with out having to top off at some point through out the day. So yesterday, after normal usage I notice about 7pm I'm still at about 65%. That's weird I thought and thought maybe the meter was "stuck". But it wasn't. It slowly dropped the rest of the evening. So at bedtime I decided to leave it unplugged all night. Over night it dropped about 10-15 ticks. I'm now on the second full day of usage and still at 11%. Nothing changed that I'm aware of and my usage is pretty consistant from day to day. A call or two, texting, FB, twitter, a pic or two, etc. I'll be interested to see what happens tomorrow after charging it back up overnight.
