PPCGeeks - Data Staying on with palringo?

Ok first off, iv hard reset 20+ times, cause im lame and i love redoing my phone... finaly got it how i want it, BUT the battery dies way faster than it ever did because the data seems to stay connected ALL day... like no joke, it will say its been connected for 9+ hours... Im pretty sure when i used palringo before it didnt keep the data connection open, but it would keep my online, but then again that doesnt seem to make sense as i type it, because if it has no net connection how did it notify me of messages... hmmm, anyone have any input on data connections staying on...
