By this time yesterday my phone was at half battery, it makes no sense. I did use the supplied charger last night rather than using the one I had from my original iPhone but I'm sure they are identical.
I looked at the two and they looked identical so I am using my old one, would be interested if it makes any difference.
Mine must be on it's third charge now - seems to be holding up better, was out of the office yesterday so a whole days use yesterday out and about so mailing and texting, using the lap timer plus a few call and it is down to 3/4s today which is better than it has been.
