Okay... sooo... the replacement phone is screwy. It kills batteries, and fast. On receipt I put in a spare battery (I had two spare batteries already to extend usability) that was known to be good and charged. It immediately showed less than full, and drained very quickly.

Today I found that even when SWITCHED OFF, the phone drains a full or nearly full battery to almost empty in an hour or two, and seems (I think, it was in my pocket so I need to confirm) to get pretty hot in the process.

When switched on it drains fast, and when connected to USB it sometimes gives the "using more power than receiving via USB" warning too.

This is really starting to drag on!

Is there a known cause for this kind of battery issue or is it as odd as it seems? My thinking is that I have to send the phone back AGAIN and seek repair/replacement.

edit: although it's "new", it was not brand-new-in-a-brand-new-box. This could be because they only replace as many things as you sent in (phone and battery) or maybe it was on a shelf. It did have all the plastic film of a new one - over the touch screen and over the camera lens inside the back cover... so...

Any advice appreciated, again... *sigh*
