why is my battery going so quick? Phone hot as well

[AC Question]

Samsung Galaxy 2
Got a new battery but it gets hot and does not keep it charge longer than 1 Hour

Is it a good-quality one? Was the phone behaving in the same way with the previous battery?

Sounds like a short or high-current drain somewhere in the device. Phones can get a bit too warm to be comfortable in a bare hand, but barely. "Hot" usually means "something's wrong".
