I upgraded to 2.1 a few days ago, and installed Spare Parts app because it worked well for me with 1.5. However my battery was draining like crazy, (I think I'm one of the few unlucky ones whose battery life went down, not up, after the upgrade) so I decided to check spare parts. When I clicked on "Network usage" the battery gobbler was found to be something called "0" (bar almost entirely full). When I clicked on it, it force closed on me and have continued to do so. This elusive "0" never made an appearance during my 1.5 days so I suspect that to be the cause of my battery drain. Does anybody know what's going on?
