Will keeping GPRS EDGE connection constantly on drain battery?

[paranormalenigma]

Hi,
I'm running Crossbow Reloaded 1.5 ROM on a G3 8125. I use T-Mobile (USA) 's GPRS data with Windows Live, however I have noticed that when Windows Live is set on the homescreen my Wizard attempts to stay connected to GPRS constantly. If i disable it from Comm manager, it simply reconnects automatically in a few seconds. Now, I have no problem with GPRS being on constantly, but I just wanted to know if it would have a significant effect on battery drain?

I know Wi-Fi does for sure, but wasn't too sure about GPRS. My question is, if I kept GPRS on 24/7 would my battery die faster? The majority of the time the connection is connected but idle, I only need it to check mail every few hours. Also, I walk around a lot from place to place. Would this cause my GPRS to disconnect/search /reconnect constantly, as with wifi (cause this would drain the battery really fast). Thanks.

I've never really tried looking at battery drain between having it on all the time and not, but before I put the fix into Crossbow Reloaded 1.5, it would disconnect and not be on all the time. I really have not noticed a difference in battery life between the two versions, so my gut is that GPRS does not drain the battery (definetly not like keeping WiFi on). I leave Bluetooth active 24 hours a day and don't notice extra battery drain with that either. YMMV.
