Battery Heating Up and Draining Quickly

I have had this problem too. My first blackberry heated up, drained the battery. Took it to the service center, they exchanged the battery and said it is all fixed. The next day, dead cell. It would not take a charge. They exchanged cells with me, updated it, sent me on my way. I was happy, until now. It is doing the samething... Charged it over night, unplugged when it was fully charged, went to work. Got my cell out to check for messages and it was dead. Took it home at lunch to try charger. It wouldn't take a charge. Changed battery and it lit up. Left the cell to charge. It had a full battery when I got home. Unplugged it, checked my messages, sent a few messages, and checked facebook. It started to feel warmer than usual. Great here we go again! Sure enough, by morning it was dead. I have ran out of batteries and paitence with this type of cell! I have had this problem too.
