Motorola KRZR K1m

I have had my KRZR for just over a year (1 week out of warranty). The problem I have is battery life. My old battery was getting 6 hours of life even if I wasn't using the phone and yes I have always let it run completely down and then charged it fully. One of the things I started to notice is the phone would say fully charged after being plugged in for about 20-30 minutes (car and 2 different wall chargers.)

I bought a new battery and I am having the exact same problems as I had before. Is this a phone issue? Anyone ahve any ideas on how to fix it? 6 hours of standby doesn't work and having 30 minutes of total talk time before having to be recharged sucks.

Thanks again.
