Query: great phone but terrible battery charge

I just wanted a simple cell phone without all the fancy things. This Samsung phone would have been perfect. Small size, cute, sturdy, etc. But, the battery charge was unpredictable. It would stay charged for only 12-36 hrs, even though I talked on it for about 15-20 mins total. My previous Samsung phone did not have this problem. Verizon replaced the battery, but there was no improvement. Since quite a number of people have made this complaint, I wonder if there is a bad batch of Samsung U340 phones. After a month, I eventually switched over to a different brand.
