New battery problem, huge drainning.

First of all, hello everybody. I'm new to the forum, but around 3 years in apple products.

I have one 3gs, ios 5.1.1, push activated with SAM, bb 5.13.04. Was working fine, last week i replaced battery. It was working fine for a day, two. After that , its a disaster, barrely handles 6 hours in standby. I guess, i will try restore. but there is another problem. Ireb is constantly crashig on win7, 32bit. I tried newest .netframework, reverting to 2.0. Same thing, crashing and debug. Anybody has any idea?

The install of the New battery is your Problem area...i would look to see if you have a defective battery and start again...

The batteries on these phones are known to drain quickly. The problem is that there are so many more things to do on your phone these days.
