You do know that phones don't come with charged batteries correct? They come with maybe a 20% charge, possibly less, possibly more. Did you think to try and charge the phone at all before sending it back? And there is a battery issue with the new 6.5 update, but it's only related to Bluetooth sitting idle/unpaired as far as I know. You also still haven't said how much you use your phone either as that could be another factor in why you're getting bad/worse battery life.
