Is there any known memory leak in Gingerbread 2.3.3 fixed by occasional reboot? Related to battery usage?
I upgraded to a 2.3.4 ROM.  I no longer have the battery drain issue, or the lag issue.  The question is whether or not it was the specific ROM or the 2.3.3 OS, but based on multiple links, here and here, I believe it is a 2.3.3 issue fixed in 2.3.4.
