Try pulling the bat and see how much after a fresh boot, then uninstall some apps to see if one has a major memory leak.
But if you made God cry, then your on your own.
Since installing .151 (maybe 3 weeks ago), my mem hasn't dropped below 30, usually stays around 35 to 40, and I never pull my battery. That's the actual .151...not some hybrid version of it.
Maybe you should try downloading .151. Also if you go to the link in my signature the last link in the original post helps too. If you need further assistance PM me.
