6700 battery life question

[dancccp]

Okay so I recently bought a used 6700. The guy gave me two batteries, the original ut starcomm and another one he said he bought off ebay. Its been my second or third day using the phone, got pretty well aquainted with the phone thanks to this forum. Although the battery life is horrible, for example I could charge the phone over night but it will only last me 3 or 4 hours ON STANDBY. So i tested with both batteries and the battery life turned out to be reletivly the same. I decided to go to a cell store and bought a battery there, turned out to be some 3rd party ebay type battery, the battery life on it is also horrible.

So my question is, what your average battery life? I ordered the oem extended batrery yesterday and hope i can get some beter results. What is the batery life with a new oem batery.

thanks
